The Slow Local Food People Are Pretty Cool – I have been hanging out with the Lawn to Food Types lately

It’s Jam Band Friday – http://www.youtube.com/watch?v=GCPSh47gHz8&feature=related

While I have understood for like 40 years that “scarcity” was the real environmental issue and that “over population” was its cause, many people are just waking up to that. On the energy front, an example would be that for the last 100 years we should have been rationing oil and using it for only the things that it was absolutely necessary for. Guess what? Gasoline and Plastics are two that would not be remotely near the top of the absolutely necessary list. Plastic bags would be ludicrous. Similarly, food should have been planted everywhere. I mean everywhere, yards, parks, ditches. Over the last 100 years good land should have been totally devoted to food and bad land left alone. We did not do that. In fact we did the exact opposite. If 100 years ago every couple could have produced no more that 2 kids….THINK about what our world would be like…Anyway the peak oil people and a lot of environmentalists are suddenly realizing that Thomas Robert Malthus was right:

http://en.wikipedia.org/wiki/Thomas_Malthus

We (homosapien) have suffered die backs before. People like to ignore the fact that Malthus had already been RIGHT when he wrote his first pamphlet. Populations of Humans, and our close cousins Neanderthal, Erectis and Hablis have fluctuated radically in the last several million years. This to the extent that the cousins are extinct. No one has ever considered that we just got lucky on that one or even worse yet that we only made it because we could hang on. That is, when our numbers get small we cooperate and stave off the end by any means necessary. These episodes are called “bottle necks” in the populations sciences and they are frightening to contemplate. Just as an example sometime roughly 50,000 years ago there may have been as few as 5,000 humans on this planet in an area the size of New York State in eastern South Africa. Humbling isn’t it? Why did we go from a population of several hundred thousand spread all over the Mediteranian and the Middle east…maybe even extending to the west coast of India…BACK to our home in Africa? Was it war, volcanic eruptions, changes in climate, famine or even disease? Who knows but this planet can not sustain 9 billion people. It just can’t. So maybe the reason I have taken up with the agricultural types is that old marijuana saying, Food will get you through times of no money better than money will get you through times of no food.

Urban farms the wave of future?

Published Friday June 26th, 2009

Permit granted for experimental farm in Moncton neighbourhood

A5

It’s always risky to count your chickens before they’re hatched, but it looks like a go for a plan to raise egg-producing hens in a suburban Moncton neighbourhood.

The Greater Moncton District Planning Commission has granted a local group a one-year temporary permit to run an urban experimental farm. The project, sponsored by Post Carbon Greater Moncton, will involve the keeping of up to four hens within the city boundaries. The group hatched the plan as a response to concerns that rising oil prices will one day force people to return to being more involved in their food production.

Is having your own hens laying eggs all it’s cracked up to be? Will the quiet hamlet (or is that omelette?) of Sunny Acres West (or is that Sunny Side Up Acres?) ever be the same? What’s the best way to run a hen-house without running off half-cocked?

That’s what the folks of the local post carbon group hope to find out through a careful study. This is not simply a “let the chicks fall where they may” approach to the issue of farm animals and humans co-existing in an urban setting, but rather something that will be carefully monitored.

And bad puns aside — the “eggspectations” of the headline is Post Carbon spokesman Michel Desjardins’ own contribution to this article, lest anyone think we’re making fun — the purpose is serious. Desjardins said yesterday the pilot project is a step towards more self-sufficiency and food security in the region. “We think food security and self-sufficiency will be a huge issue in the future.”

Projected food, energy demands seen to outpace production

MADISON — With the caloric needs of the planet expected to soar by 50 percent in the next 40 years, planning and investment in global agriculture will become critically important, according a new report released today (June 25).

The report, produced by Deutsche Bank, one of the world’s leading global investment banks, in collaboration with the University of Wisconsin-Madison’s Nelson Institute for Environmental Studies, provides a framework for investing in sustainable agriculture against a backdrop of massive population growth and escalating demands for food, fiber and fuel.

“We are at a crossroads in terms of our investments in agriculture and what we will need to do to feed the world population by 2050,” says David Zaks, a co-author of the report and a researcher at the Nelson Institute’s Center for Sustainability and the Global Environment.

By 2050, world population is expected to exceed 9 billion people, up from 6.5 billion today. Already, according to the report, a gap is emerging between agricultural production and demand, and the disconnect is expected to be amplified by climate change, increasing demand for biofuels, and a growing scarcity of water.

“There will come a point in time when we will have difficulties feeding world population,” says Zaks, a graduate student whose research focuses on the patterns, trends and processes of global agriculture.

Although unchecked population growth will put severe strains on global agriculture, demand can be met by a combination of expanding agriculture to now marginal or unused land, substituting new types of crops, and technology, the report’s authors conclude. “The solution is only going to come about by changing the way we use land, changing the things that we grow and changing the way that we grow them,” Zaks explains.

The report notes that agricultural research and technological development in the United States and Europe have increased notably in the last decade, but those advances have not translated into increased production on a global scale. Subsistence farmers in developing nations, in particular, have benefited little from such developments and investments in those agricultural sectors have been marginal, at best.

Deep Geothermal Energy – From the winds of the Jetstream to the Bowels of the earth

Deep in Bedrock, Clean Energy and Quake Fears

Published: June 23, 2009

BASEL, Switzerland — Markus O. Häring, a former oilman, was a hero in this city of medieval cathedrals and intense environmental passion three years ago, all because he had drilled a hole three miles deep near the corner of Neuhaus Street and Shafer Lane.

An earthquake halted Markus O. Häring’s geothermal project in Basel, Switzerland.

A blog about energy, the environment and the bottom line.

Share your thoughts.

He was prospecting for a vast source of clean, renewable energy that seemed straight out of a Jules Verne novel: the heat simmering within the earth’s bedrock.

All seemed to be going well — until Dec. 8, 2006, when the project set off an earthquake, shaking and damaging buildings and terrifying many in a city that, as every schoolchild here learns, had been devastated exactly 650 years before by a quake that sent two steeples of the Münster Cathedral tumbling into the Rhine.

Hastily shut down, Mr. Häring’s project was soon forgotten by nearly everyone outside Switzerland. As early as this week, though, an American start-up company, AltaRock Energy, will begin using nearly the same method to drill deep into ground laced with fault lines in an area two hours’ drive north of San Francisco.

Residents of the region, which straddles Lake and Sonoma Counties, have already been protesting swarms of smaller earthquakes set off by a less geologically invasive set of energy projects there. AltaRock officials said that they chose the spot in part because the history of mostly small quakes reassured them that the risks were limited.

Like the effort in Basel, the new project will tap geothermal energy by fracturing hard rock more than two miles deep to extract its heat. AltaRock, founded by Susan Petty, a veteran geothermal researcher, has secured more than $36 million from the Energy Department, several large venture-capital firms, including Kleiner Perkins Caufield & Byers, and Google. AltaRock maintains that it will steer clear of large faults and that it can operate safely.

But in a report on seismic impact that AltaRock was required to file, the company failed to mention that the Basel program was shut down because of the earthquake it caused. AltaRock claimed it was uncertain that the project had caused the quake, even though Swiss government seismologists and officials on the Basel project agreed that it did. Nor did AltaRock mention the thousands of smaller earthquakes induced by the Basel project that continued for months after it shut down.

The California project is the first of dozens that could be operating in the United States in the next several years, driven by a push to cut emissions of heat-trapping gases and the Obama administration’s support for renewable energy.

Reported today, Australia opens the second round of the Geothermal Drilling Program with “The Minister for Resources and Energy, Martin Ferguson AM MP inviting geothermal companies to submit applications for funding under Round 2 of the A$50 million (US$39.8 million) Geothermal Drilling Program, which opened today.

Round 2 funding will provide grants of up to A$7 million (US$5.6 million) on a matching-funding basis to support the drilling of deep geothermal wells and help finance geothermal proof-of-concept projects.
Geothermal energy producers pump water below ground (sometimes as deep as 5 kilometers (3.1 miles)), where it is heated by ‘hot rocks’. The heat energy is then used to generate electricity.

Ferguson said: “Geoscience Australia estimates that if just one per cent of Australia’s geothermal energy was extracted it would equate to 26,000 times Australia’s total annual energy consumption. “Geothermal energy is a renewable energy source with enormous potential in Australia; however, the Government recognizes technical development costs are high.

“The Australian Government is pleased to be able to support drilling at the first stage of development as part of its A$4.5 billion (US$3.5 billion) Clean Energy Initiative.

“Geothermal energy is important because it has the capacity to produce baseload power, diversify Australia’s energy supply and increase our energy security.

“The Australian Government has set a target for 20 per cent of Australia’s electricity generation to come from renewable sources by 2020; a policy which will likely require an additional 45,000 gigawatt-hours of electricity generation from renewable sources.

There Is Enough Wind Power To Generate The Electricity To Power The Entire World

A very hairy paper from three Harvard Grad students purports to show that especially the USA, Canada and China have all the wind power that we need to generate all the electricity we currently need. The rest of the world does too but not within it’s own confines. In other words some areas like say the Tibetan Uplands have way more than they need and maybe landlocked Germany does not. So they would have to trade but the net wind power to generate the electricity exists according to:

Abstract

The potential of wind power as a global source of electricity is assessed by using winds derived through assimilation of data from a variety of meteorological sources. The analysis indicates that a network of land-based 2.5-megawatt (MW) turbines restricted to nonforested, ice-free, nonurban areas operating at as little as 20% of their rated capacity could supply >40 times current worldwide consumption of electricity, >5 times total global use of energy in all forms. Resources in the contiguous United States, specifically in the central plain states, could accommodate as much as 16 times total current demand for electricity in the United States. Estimates are given also for quantities of electricity that could be obtained by using a network of 3.6-MW turbines deployed in ocean waters with depths <200 m within 50 nautical miles (92.6 km) of closest coastlines.

Wind could power the entire world
Jeremy Hance
mongabay.com
June 22, 2009

Wind power may be the key to a clean energy revolution: a new study in the Proceedings of the National Academy of Science finds that wind power could provide for the entire world’s current and future energy needs.

To estimate the earth’s capacity for wind power, the researchers first sectioned the globe into areas of approximately 3,300 square kilometers (1,274 square miles) and surveyed local wind speeds every six hours. They imagined 2.5 megawatt turbines crisscrossing the terrestrial globe, excluding “areas classified as forested, areas occupied by permanent snow or ice, areas covered by water, and areas identified as either developed or urban,” according to the paper. They also included the possibility of 3.6 megawatt offshore wind turbines, but restricted them to 50 nautical miles off the coast and to oceans depths less than 200 meters.

Using this criteria the researchers found that wind energy could not only supply all of the world’s energy requirements, but it could provide over forty times the world’s current electrical consumption and over five times the global use of total energy needs.

Turning to the world’s two largest carbon emitters, China and the United States, the researchers found that wind power has the potential to easily supply both nations.


Windmill for pumping water in Kenya

Wind turbines for power generation in Maui.

“Large-scale development of wind power in China could allow for close to an 18-fold increase in electricity supply relative to consumption reported for 2005,” the researchers write. “The bulk of this wind power, 89%, could be derived from onshore installations. The potential for wind power in the U.S. is even greater, 23 times larger than current electricity consumption, the bulk of which, 84%, could be supplied onshore.”

Expanding their view to the top ten carbon emitters, the researchers found that Russia, Canada, and the United States (in this order) had the greatest capacity for wind power. However, they note that much of the area available for wind power in Russia and Canada is far from any cities, making their construction costly. In addition, the authors note that the public may oppose wind turbines in particular areas, especially remote, ecologically sensitive regions. Still, they conclude that “despite these limitations, it is clear that wind power could make a significant contribution to the demand for electricity” in most high carbon emitting countries.

From Infinity And Beyond – Electricity from kites…yes yes Kites

After an extended meditation like I just concluded on the Federal Energy Tax Credits (please click 2008 elections, international environmental groups and religion categories for more examples),  I am always at a loss for where to go next. I find it useful to just blow it out! So from Live Science and Yahoo I bring you some of the most implausible energy thoughts ever encountered by man:

Powerful Ideas: Miles-High Kites Could Generate Electricity

Editor’s Note: This occasional series looks at powerful ideas — some existing, some futuristic — for fueling and electrifying modern life.

The sky might literally be the limit for wind power — rotors spinning miles high could help supply electricity worldwide.

“There is a huge amount of energy available in high-altitude winds,” said researcher Ken Caldeira at the Carnegie Institution’s Department of Global Ecology in Stanford, Calif. “These winds blow much more strongly and steadily than near-surface winds, but you need to go get up miles to get a big advantage. Ideally, you would like to be up near the jet streams, around 30,000 feet.”

All told, if wind turbines miles above the planet were tethered to 10 percent of the world’s land, there is enough energy in these jet stream winds to meet world demand 100 times over, researchers said.

Jet streams are meandering belts of fast winds at altitudes between 20,000 and 50,000 feet. They shift seasonally, but are otherwise persistent features in the atmosphere. Jet stream winds are generally steadier and 10 times faster than wind near the ground, making them a potentially vast and dependable source of energy.

But how to capture the wind so high?

Kites and tethers

A number of technological schemes have been proposed to harvest energy from these high-altitude winds, including tethered, kite-like wind turbines lofted miles high. Up to 40 megawatts of electricity could be generated by current designs and transmitted to the ground via tether.

Using 28 years of weather data, the researchers developed the first-ever global survey of high-altitude wind energy.

“We found the highest wind power densities over Japan and eastern China, the eastern coast of the United States, southern Australia, and north eastern Africa,” said researcher Cristina Archer, an atmospheric scientist at California State University in Chico.

Abstract: The objectives of this study are to combine historical observations and state-of-the-art numerical models (MM5/CALMET system) to map the spatial distribution of wind resources in high resolution, and to help foster a deeper understanding of the wind power potential over southern China (Guangdong). Hourly wind fields were simulated for three entire years (2004-2006). It found that almost 70% of the time, the wind speed along the coast of Guangdong is over 5 m/s, which is deemed a baseline magnitude for typical wind turbines. Spatial plots of the wind speed and power and their variations over Guangdong Province for the three years are also presented.

For the SEX part of it…Generating energy from the jet stream …well it is awful high up there (40-50 miles), really really cold (100 degrees below zero) and really close to the cosmic rays…and it has been around for awhile. I mean looking up is to dream right?

KINETIC ENERGY CREATES ELECTRICITY

Posted by admin | Green News | Wednesday 21 January 2009 2:43 pm

 

 

Dutch astronaut Dr Wubbo Ockels has successfully demonstrated i Netherlands his new energy concept. He has flown a high-flying energy kite, creating kinetic energy from huge radio-controlled highflying kites. He has designed ‘ladder-mills’ to store the kinetic energy and convert it into electricity.
Three such ladder-mills provide enough electricity to power one city. The experiment was carried out along the northern coastline of The Netherlands where there’s usually more than enough wind to raise the gigantic kites into.The radio- controlled, high-flying kites can create some 10,5kw electricity each, Dr Ockels told a local radio station.High-altitude kites could be used to generate clean energy at a cost comparable with that of fossil fuel generation , researchers claim.The “Ladder-Mill” is a chain of controllable wing-like kites attached to a looped cable stretching more than five miles into the sky.Strong high altitude winds acting on the “kitewings” produce as upward force on one side of the loop and a downward force on the other, causing it to rotate.The slowly turning cable drives a power generator in the Ladder-Mill base station.Although the concept sounds far fetched, its developers at Delft Technical University in the Netherlands hope to build a working model in the next four years.

They claim one Ladder-Mill could generate 100 megawatts of electricity, compared with only a few megawatts from a conventional wind turbine.

Winds at 30,000ft are 20 times more powerful than at sea level.

Professor Ockels, an ex-astronaut and head of the European Space Agency’s education office, told The Engineer magazine: “Above a certain altitude there is a massive amount of wind power.

The kite is used to do certain things; one kite or many kites are applied to achieve certain purposes, objectives, or tasks, that is: applications. Humans have applied the kite to bring perceived benefits during peace and war alike. New applications for the kite continue to be found. Only some innovative applications appear in national patents; others are communicated in newspapers, magazines, books, and internet pages. Air kites, water kites, bi-media kites, fluid kites, gas kites, kytoons, paravanes, soil kites, solid kites, and plasma kites have niche applications that are furthering the interests of humans. Non-human-made kites have applications; some spiders make use of kiting.

There is growing demand for energy across the globe. Demand for electricity is forecast to double from 2002 to 2025. Yet the existing supplies may not cope with this demand, and significant investment is needed in new generation systems that also meet higher efficiency and environmental standards.

Ceramic Fuel Cells Limited (CFCL) is providing solutions.

CFCL is a world leader in developing solid oxide fuel cell (SOFC) technology to provide reliable, energy efficient, high quality, and low-emission electricity from widely available natural gas and renewable fuels. CFCL is developing SOFC products for small-scale on-site micro combined heat and power (m-CHP) and distributed generation units that co-generate electricity and heat for domestic use

Then there are microturbines:

http://www.energy.ca.gov/distgen/equipment/microturbines/microturbines.html

Microturbines are small combustion turbines that produce between 25 kW and 500 kW of power. Microturbines were derived from turbocharger technologies found in large trucks or the turbines in aircraft auxiliary power units (APUs). Most microturbines are single-stage, radial flow devices with high rotating speeds of 90,000 to 120,000 revolutions per minute. However, a few manufacturers have developed alternative systems with multiple stages and/or lower rotation speeds.

Microturbines are nearing commercial status. Capstone, for example, has delivered over 2,400 microturbines to customers (2003). However, many of the microturbine installations are still undergoing field tests or are part of large-scale demonstrations.

  • Unrecuperated (or simple cycle) microturbines, which have lower efficiencies, but also lower capital costs.

While some early product introductions have featured unrecuperated designs, the bulk of developers’ efforts are focused on recuperated systems. The recuperator recovers heat from the exhaust gas in order to boost the temperature of the air stream supplied to the combustor. Further exhaust heat recovery can be used in a cogeneration configuration. The figure below illustrates a recuperated microturbine system.

Vertical-Axis Wind Turbines: The Future of Micro Wind? [w/video]

Published on June 20th, 2008

34 Comments

Posted in business, wind energy

 Walking the floor of WINDPOWER 2008, the annual conference and trade show for the wind energy industry, one couldn’t help but be transfixed by all of the different types of turbines – at least I couldn’t. The wind turbine has become the iconic of clean, renewable energy. But the classic three-bladed horizontal axis wind turbine, with its gracefully swooping blades, has become the symbol of not only renewable energy, but also of environmental consciousness and ecological possibility.

Despite the ubiquity of the three-bladed turbine, the oft-overlooked vertical-axes turbines are making quite a splash in the world of wind energy, especially in small and micro-applications. So what’s all the fuss about? Vertical-axis turbines apparently do not suffer from some of the same problems that plague small wind applications in urban settings including, aesthetic concerns, space requirements and sound levels

Fed Credits For Solar Water Heaters – Once it is paid for it is free for life

Or at least for the life of the equipment. (it’s jam band friday – http://www.youtube.com/watch?v=fhNrqc6yvTU)

I mean this is the ultimate irony in the utility world. Heating water with anything other than the sun which is free is a crime. I mean think about it. Why? First the Tax Credit

Not there silly here:

No pools or hot tubs dam nit…we can’t have everything being free. So these things come in all shapes and sizes:

Solar Water Heaters

Solar water heaters—also called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free.

How They Work

Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don’t.

Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

Three types of solar collectors are used for residential applications:

  • Flat-plate collector

    Glazed flat-plate collectors are insulated, weatherproofed boxes that contain a dark absorber plate under one or more glass or plastic (polymer) covers. Unglazed flat-plate collectors—typically used for solar pool heating—have a dark absorber plate, made of metal or polymer, without a cover or enclosure.

  • Integral collector-storage systems

    Also known as ICS or batch systems, they feature one or more black tanks or tubes in an insulated, glazed box. Cold water first passes through the solar collector, which preheats the water. The water then continues on to the conventional backup water heater, providing a reliable source of hot water. They should be installed only in mild-freeze climates because the outdoor pipes could freeze in severe, cold weather.

  • Evacuated-tube solar collectors

    They feature parallel rows of transparent glass tubes. Each tube contains a glass outer tube and metal absorber tube attached to a fin. The fin’s coating absorbs solar energy but inhibits radiative heat loss. These collectors are used more frequently for U.S. commercial applications.

There are two types of active solar water heating systems:

  • Direct circulation systems

    Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.

  • Indirect circulation systems

    Pumps circulate a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.

In this day and age everybody should know what a geothermal heat pump is, but if not:

http://en.wikipedia.org/wiki/Geothermal_heat_pump

A geothermal heat pump (GHP) system is a central heating and/or air conditioning system that actively pumps heat to or from the shallow ground. It uses the earth as either a source of heat in the winter, or as a coolant in the summer. This design takes advantage of moderate temperatures in the shallow ground to boost efficiency and reduce operational costs. It may be combined with solar heating to form a geosolar system with even greater efficiency.

Geothermal heat pumps are also known by a variety of other names, including geoexchange, earth-coupled, earth energy, ground-source or water-source heat pump. The engineering and scientific community tend to prefer the terms “geoexchange” or “ground-source heat pumps” because very little of the heat originates from true geological sources.[1] Instead, these pumps draw energy from shallow ground heated by the sun in the summer. Genuine geothermal energy from the core of Earth is available only in places where volcanic activity comes close to the surface, and can usually be extracted without the help of a heat pump.

:}

Anyway the first one on the list is my favorite becaused the closed loop is the most flexible. You can run the piping horizontal to the ground if there are mining issues. Or you can go straight down like a well.

I used to be fascinated by Open  Loop systems because they seem so natural. Essentially if you are near a lake or a deep pond you vent your waste heat there. But now I see them as potential environmental disruptors but again this about tax credits. They don’t really care about the environment.

As you can see they all have open loop options because a heat exchanger doesn’t care where it puts it’s heat.

The final version is pretty exotic. I guess they are appropriate if you are in an extreme environment:

http://www.renovation-headquarters.com/heating-geothermal.htm

Direct Expansion (DX): A geothermal heat pump system in which the refrigerant is circulated in pipes buried in the ground, rather than using a heat transfer fluid, such as water or antifreeze solution in a separate closed loop, and fluid to refrigerant heat exchanger. A DX system includes all of the equipment both inside and outside the house. DX systems may be single or multi-speed.

 http://www.alibaba.com/product/earthenergysolutions-11290116-10854411/Geothermal_Heat_Pump_Waterless_Direct_Expansion.html

or

http://www.geothermix.com/english/product/direct1.html

Direct Expansion “DX” Units

A direct earth coupled heat pump or “DX” heat pump is one that has its refrigerant evaporator / condenser in direct thermal contact with the earth from which heat is either extracted from during the heating mode or introduced to during the cooling mode of operation.

The general refrigeration cycle of our DX machine is similar in nature to a conventional water-to-air or water-to-water heat pump in that there exist a compressor, expansion device, reversing valve, and refrigerant-to-air heat exchanger. Conventional technology concerned with heat pumps relies upon the transfer of heat from the ground by means of a secondary heat exchanger system and working fluid, e.g., water, which is pumped to the geothermal unit located in the heated structure. The conventional heat pump has it’s own internal primary heat exchanger which extracts heat (heating mode) or rejects heat (cooling mode) from this water, which is then pumped back to the earth to be reheated.

DX systems similarily use a ground coil system, however, the working fluid is a refrigerant and the copper groundloop is the primary heat exchanger. Such geothermal heat exchange is an efficient and effective way of achieving heat exchange in heating and air conditioning systems, and especially heat pump type systems. Since the ground temperature is relatively constant at 48 °F at a depth below the frost line, the available heat is constant.

DX Heat Cycle (Gif 11K)

The elimination of the secondary earth heat exchanger (typically plastic in nature) and its associated working fluid reduces the temperature difference required between the ground and the evaporating refrigerant yielding a higher suction pressure than a conventional system under similar circumstances and thus a higher efficiency.

I like the closed loop the best:
