Hydropower In A Small Beautiful Package – New Development

Beautiful power generation is the theme of this meditation. This grows out of a comment by a friend. We were talking about wind farms and all the silly criticism of them, the worst of which is that they are ugly. I said I found them elegant and he said he found them beautiful. Thus the theme. Here is a post about small hydro. The article includes a build up about large hydrodams and the negative impact on the environment as well as data about Germany where these dams were developed. I have only included the info about the new type dam itself but please feel free to read the rest.

Small Is Beautiful in Hydroelectric Power Plant Design: Invention Could Enable Renewable Power Generation at Thousands of Unused Sites

ScienceDaily (Oct. 20, 2010)

dot dot dot as they say…

A solution to all of these problems has now been demonstrated, in the small-scale hydroelectric power plant developed as a model by a team headed by Prof. Peter Rutschmann and Dipl.-Ing. Albert Sepp at the Oskar von Miller-Institut, the TUM research institution for hydraulic and water resources engineering. Their approach incurs very little impact on the landscape. Only a small transformer station is visible on the banks of the river. In place of a large power station building on the riverside, a shaft dug into the riverbed in front of the dam conceals most of the power generation system. The water flows into a box-shaped construction, drives the turbine, and is guided back into the river underneath the dam. This solution has become practical due to the fact that several manufacturers have developed generators that are capable of underwater operation — thereby dispensing with the need for a riverbank power house.

The TUM researchers still had additional problems to solve: how to prevent undesirable vortex formation where water suddenly flows downward; and how to best protect the fish. Rutschmann and Sepp solved two problems with a single solution — by providing a gate in the dam above the power plant shaft. In this way, enough water flows through to enable fish to pass. At the same time, the flow inhibits vortex formation that would reduce the plant’s efficiency and increase wear and tear on the turbine.

The core of the concept is not optimizing efficiency, however, but optimizing cost: Standardized pre-fabricated modules should make it possible to order a “power plant kit” just like ordering from a catalog. “We assume that the costs are between 30 and 50 percent lower by comparison with a bay-type hydropower plant,” Peter Rutschmann says. The shaft power plant is capable of operating economically given a low “head” of water of only one to two meters, while a bay-type power plant requires at least twice this head of water. Series production could offer an additional advantage: In the case of wider bodies of water, several shafts could be dug next to each other — also at different points in time, as determined by demand and available financing.

A Solar Farm That Is Beautiful – How not to waste energy

I am going to be posting things I LIKE this week. It is my summer fun. This is a great site. Please RSS.

Behold the Gorgeous Solar Farms of Le

Mées, France

  • May 27, 2011 • 12:10 pm PDT

The energy company Efinity opened two new solar-power farms in Le Mées in north-central France this month. They’re huge. Together they occupy 89 acres, generating enough electricity for 9,000 families. They were also designed with the landscape in mind. The panels were installed without concrete foundations, which means when their 20-year lifespan is over and they’re removed, there will be healthy land left behind, and grasses are being planted so sheep can graze among them.

But what’s most remarkable about these solar farms is that they’re really aesthetically pleasing. Set on the rolling hills, they look like some sort of Frank Gehry installation. Carbon aside, they’re just much nicer to look at than a coal plant.

Wasted Energy – Very cool blog

I started a meditation on wasted energy last Friday by looking at all the energy we waste by “flaring” natural gas at drilling rigs. We burn more than we use. Then I got distracted by the Corps of Engineers opening the Morganza  Spillway which is a huge environmental deal. So I come back to the meditation today. I googled up the issue and this site popped up. It’s a pretty cool blog. They haven’t posted since April so I am hoping I am not hyping a dead blog.

The Palest Green

Posted by wastedenergy on April 6, 2011

Now that enough time has passed to witness what is really happening in Fukushima, I am ready to pass judgment. I notice a lot of other commentators offered their two cents up immediately, as if they could tell the full scale of the disaster from the first few hours. Not me, though. I knew something strange was afoot the instant it happened, but it’s important to keep in mind that one must always do the necessary homework before making ultimate determinations of value. Now that time has come.

The most common argument I see supposed “environmentalists” making in favor of “nuclear power” (which is a misnomer since it is actually a drain on energy over the long run) is that it is “better than coal.” “It’s carbon neutral,” they say, as if to suggest that were the only criterion that mattered, and also as if to ignore the full energy-consumptive effects of the nuclear fuel cycle from mining to ultimate disposal (it’s supposed to get disposed ultimately, right?). But the path to “clean” nuclear energy is laid with many other booby traps, and it takes an eye open to truth and closed to propaganda to catch them all.

In nature, the color yellow often means “Don’t touch me, I will hurt you.”

As I see things today, the quest for nuclear power, hailed as tomorrow’s energy source by those so obsessed with technocracy that they blind themselves to the big picture, represents better than almost any other story our civilization’s descent into madness. We have become truly power-obsessed, seeking cheap thrills today and tossing tomorrow to the winds. Let our children handle the nuclear waste, we keep saying. Well, the children have arrived, and they are ready to take the reins of power now, and we still aren’t any closer to figuring out what to do with this stuff, which keeps piling up in spent fuel pools vulnerable to release into the environment from earthquakes, volcanoes, meteor strikes, acts of sabotage, and all the other hazards that are a natural part of life on Planet Earth. So what makes today’s nuclear scientists so certain that tomorrow we will finally come up with the magic solution that will allow us to seal this stuff forever behind closed doors, especially if we continue to create even more? It’s time to stop kicking the can ever further down the road and face up to the reality we’ve created for ourselves.

Nuclear fission and radiation are natural parts of our existence. Decaying radioactive isotopes are what power the Earth’s geothermal heat, much like nuclear fusion powers radiation from the Sun. We tell ourselves there cannot be a hazard here since it is always around in one form or another. But we overdo it sometimes, and just as with oil depletion, we trick ourselves into thinking what we are doing is perfectly natural by suggesting “there’s always going to be some, so it can’t be so bad.” That is, once again, the continuum fallacy. We presume that just because we cannot draw a clear line between one phenomenon and its much larger version, that there must be no difference at all. The disaster at Fukushima, which has caused radiation levels to spike to millions of times background levels, has proven conclusively that there are real clear and ever-present dangers associated with even the most carefully operated nuclear power reactors, and the silver lining in the event is that it has brought these as well as the dangers associated with the back end of the nuclear cycle into the forefront of discussion and back into clear view. Such a perspective is necessary if we are to take an objective look at the advantages and drawbacks of our different energy options, something many players with vested political and economic interests are not particularly keen on seeing.

Evolutionary lessons for wind farm efficiency

Wednesday, 4 May 2011

Evolution is providing the inspiration for University of Adelaide computer science research to find the best placement of turbines to increase wind farm productivity.

Senior Lecturer Dr Frank Neumann, from the School of Computer Science, is using a “selection of the fittest” step-by-step approach called “evolutionary algorithms” to optimise wind turbine placement. This takes into account wake effects, the minimum amount of land needed, wind factors and the complex aerodynamics of wind turbines.

“Renewable energy is playing an increasing role in the supply of energy worldwide and will help mitigate climate change,” says Dr Neumann. “To further increase the productivity of wind farms, we need to exploit methods that help to optimise their performance.”

Dr Neumann says the question of exactly where wind turbines should be placed to gain maximum efficiency is highly complex. “An evolutionary algorithm is a mathematical process where potential solutions keep being improved a step at a time until the optimum is reached,” he says.

“You can think of it like parents producing a number of offspring, each with differing characteristics,” he says. “As with evolution, each population or `set of solutions’ from a new generation should get better. These solutions can be evaluated in parallel to speed up the computation.”

Other biology-inspired algorithms to solve complex problems are based on ant colonies.

“Ant colony optimisation” uses the principle of ants finding the shortest way to a source of food from their nest.

“You can observe them in nature, they do it very efficiently communicating between each other using pheromone trails,” says Dr Neumann. “After a certain amount of time, they will have found the best route to the food – problem solved. We can also solve human problems using the same principles through computer algorithms.”

Dr Neumann has come to the University of Adelaide this year from Germany where he worked at the Max Planck Institute. He is working on wind turbine placement optimisation in collaboration with researchers at the Massachusetts Institute of Technology.

“Current approaches to solving this placement optimisation can only deal with a small number of turbines,” Dr Neumann says. “We have demonstrated an accurate and efficient algorithm for as many as 1000 turbines.”

The researchers are now looking to fine-tune the algorithms even further using different models of wake effect and complex aerodynamic factors.

The Illinois Stewardship Alliance Needs Your Help

I hardly ever do this. Raise money for another organization. But these people are so cool and so important, I say Open Your Wallets People.

ISA logo
Greetings!
I am writing to you today to make a serious plea for your financial support for Illinois Stewardship Alliance (ISA). ISA is the only statewide advocacy organization dedicated to advancing local food systems in Illinois and we can’t do it without your help now.

ISA is a small non-profit: we employ 2 full time and 2 part-time staff yet we are doing so much to support local food systems from Springfield to Washington DC.  Current initiatives include:

·         The recent formation of the Illinois Local Food and Farm Grassroots Policy Advisory Committee to provide a forum for local food producers, local food/sustainable agriculture organizations and citizens to discuss how policies impact Illinois’ local food systems and how to address them.

·         The Campaign for Cottage Food supports aspiring local food entrepreneurs by permitting home processing for low-risk foods like jams, jellies and baked goods.

·         Buy Fresh Buy Local Central Illinois – We are gearing up for our fourth year of spreading the “Buy Fresh Buy Local” message and expanding to cover 34 counties in central Illinois. The campaign connects local food producers with restaurants, retailers, consumers and others looking for local food to encourage support of local farmers and increase the economic viability of small farms.

·         Local Flavors, our successful farm-to-restaurant series is going statewide!  This August we plan to hold events across the state, from barbecue joints to white table cloth restaurants, helping to build relationships between farmers and buyers.

·         ISA was thrilled to announce the first round of18 Golden Beet Awards to recognize the innovative activities bringing local foods to Illinois communities and raise awareness about the important work happening in schools, at farmers markets and .

·         The Springfield Area Local Food Task Force conducted an economic impact study and we are spreading the word about how we can boost our local economy ($100 million in new farm income if residents from Sangamon and surrounding counties purchased just 15% of their food from local farmers).  The Task Force formed a sub-committee who is organizing a Farm-to-School Summit to be held in Springfield in the fall of 2011.

ISA staff is also providing leadership and ensuring grassroots representation on the Illinois Local Food, Farms and Jobs Council, Illinois Farm to School Network Advisory Committee, Illinois Sustainable Agriculture and Research Education Professional Development Program Advisory Committee and more.

We have set a short-term fundraising goal of $17,500 to address to maintain operations until additional funding comes through.  We currently have raised $7,280 of that total and are seeking $5,000 in sponsorships. We have several strategies for reaching our goal and part of that is asking for your help.  We need to raise $5,220 from direct donations and memberships from people like you; people who care about where their food comes from and want to support Illinois small farms and local foods.

Solar Plane Will Make First European Flight – Actually land at a real airport

While the Solar Impulse has flown around the world it has never landed at a major airport or filed a real flight plan. This is too cool for words. I know this is not an Earth Day thing but it should be.

Solar Impulse on stand-by from Monday

author: Bernard Schopfer

2011-04-28

In these last few weeks the entire Solar Impulse team has been busy doing “test flights” in the Payerne area, to test the satellite communication systems developed by Swisscom, and also the air traffic integration procedures. The support received from the aviation authorities in the overflight and destination countries has been extremely positive and constructive.

For the European solar flight campaign the Solar Impulse team, sponsored by the European Commission, has chosen Brussels as the 1st international destination. The airplane will be shown in the European capital from 23 to 29 May 2011 and will then attempt to reach Paris-Le Bourget, where it is expected as a “Special Guest” at the 49th International Paris Air Show.

“These tests have been extremely successful”, says an elated Bertrand Piccard. “Now, here we are in the definitive phase: it’s no longer a question of tests, but the real thing. And the next flights will not be made in the “familiar cocoon” of Payerne aerodrome, but in the whole of Europe…” Rather like a sailing ship that has undergone coastal trials, and is now set to cross its first ocean!

“We will be in stand-by mode from Monday”, explains André Borschberg, who will pilot the HB-SIA between Payerne and Brussels. “And we definitely mean to take the first opportunity that comes along, since we can never be sure of the weather conditions and whether they will allow us to do this flight on a particular date. With Solar Impulse we are confined to what we can do with the technology at the present time, and safety is our number one priority.”

Earth Day 2011 – Here is the first post

I am probably going to post Earth Day stuff for the next week. I see it as a way to hook up with old friends like today’s Shawna Coronado or new friends unknown.

http://www.chicagonow.com/blogs/gardening-nude/2011/04/green-tip-6-earth-day-is-every-day-just-ask-my-plastic-bag-thong-underwear-oak-tree-art.html

Green Tip #6-Earth Day Is Every Day, Just Ask My Plastic Bag Thong Underwear Oak Tree Art

Plastic Bag Thong.jpg

Earth Day should be every day. Just ask my oak tree which currently has a plastic bag hanging in it 28 feet up that remarkably resembles a pair of thong underwear. No kidding.

Why are we celebrating the earth just one day of the year? It has given us everything we have, wear, and eat – yep, even thong underwear. Without the earth humanity would not exist. With the earth we exist. Pure and simple.

Stop messing around people – pick up your trash so it does not get caught in a tree for some bird to get tangled in. Recycle your glass, plastic, and paper, so we save our natural resources. Make a difference every day, not just on Earth Day – it is the right thing to do.

Now. Who’s going to climb 28 feet up to help me get the thong out of the tree? Volunteers?
