Wave Energy Project

The U.S. Department of Energy has accepted 92 teams from industry and academia to compete in its Wave Energy Prize program that seeks to encourage the development of wave energy conversion devices.

The program, which was introduced in April by the DOE Office of Energy Efficiency and Renewable Energy during the National Hydropower Association’s Annual Conference in Washington, D.C., is a design-build-test competition that supports the department’s goal of making marine hydrokinetic generation more competitive with traditional forms of production.

Teams will be competing for a total prize purse that totals more than $2 million.

“We’re extremely pleased with both the quantity of teams and the diversity of participants reflecting broad expertise from so many established companies in the ocean energy space, universities, and newcomers to the industry,” said Julie Zona, Wave Energy Prize administrator.

Since registration for the program closed June 30, teams are working on the first requirement for the prize — a technical submission describing their concepts, which is due later this month. A panel will then select up to 20 of the top teams by mid-August, with those groups invited to build a 1/50th scale model for small-tank testing.

Nuclear Power Is Dangerous – I do not think I can say that often enough

Posted on by

From Three Mile Island, to Chernobyl, to Fukushima, nuclear power has soaked up trillions of $$$ and awarded planet Earth with poisonous outputs  and death and destruction. The proponents point to the trillions of kilowatts generated without carbon emissions. The bottom line is what to we do to shut them down? Safely. The answer is – there is none. So we are in jeopardy for thousands of years.

No One Knows What to Do With Fukushima’s Endless Tanks of Radioactive Water

Posted By Eliza Strickland on Jun 09, 2015

This is what passes for good news from Fukushima Daiichi,  the Japanese nuclear power plant devastated by meltdowns and explosions after a cataclysmic earthquake and tsunami in 2011: By the end of last month, workers had succeeded in filtering most of the 620,000 tons of toxic water stored at the site, removing almost all of the radioactive materials.

After numerous false starts and technical glitches, most of the stored water has been run through filtration systems to remove dangerous strontium-90, as well as many other radionuclides. TEPCO, the Japanese utility that operates the power plant, trumpeted the achievement: “This is a significant milestone for improving the environment for our surrounding communities and for our workers,” said Naohiro Masuda, TEPCO’s chief decommissioning officer, in a press release.

But it’s not quite so easy to bounce back from a nuclear disaster of this scale. For one thing, don’t take TEPCO’s statement too literally: No one is living in the “surrounding communities”—they’re far too contaminated for human habitation. Furthermore, the filtered water is still full of tritium, a radioactive version of hydrogen. (When two neutrons are added to the element, it becomes unstable, prone to emitting electrons.) Tritium bonds with oxygen just like normal hydrogen does, to produce radioactive “tritiated water.” It’s impractical—or at least extremely difficult and expensive—to separate tritiated water from normal water.

Tesla Puts Out A New Battery – The world goes apeshit

Why is Elon Musk worshiped so? He blows a rocket landing and everyone says it “Was nicely played”. In the passed week or so, his companies have both launched a space capsule about a mile in the air and brought it back to the ground my parachute. This was done 50 years ago by NASA. And announce a new battery for the residential housing market which is anything but new. He is a carny shill if ever I saw one. I shall continue this rant over at myspace/dougnicodemus  if anyone is interested.

Will Tesla’s Battery for Homes Change the Energy Market?

Tesla did not reveal the price of its larger batteries for businesses and utilities, but it will sell residential models for $3,000—$3,500

May 4, 2015 |By Davide Castelvecchi and Nature magazine | Véalo en español

Tesla Motors, the electric-car maker based in Palo Alto, California, has announced that it will sell versions of its battery packs directly to consumers to help to power their homes, as well as to businesses that run larger facilities, and utility companies.

At a press conference in Los Angeles on April 30, the company’s charismatic founder Elon Musk said that the firm’s lithium-ion batteries would enable economies to move to low-carbon energy sources. Solar energy sources are erratic—but by storing their energy and then releasing it when required, batteries could solve that problem, he said.

Many other companies also sell stationary battery storage for buildings and for power grids—but analysts say that the technology is still too expensive for widespread use. Here, Nature explores whether Tesla’s announcement might change the game.

Rethinking extinction

by

The idea that we are edging up to a mass extinction is not just wrong – it’s a recipe for panic and paralysis

The way the public hears about conservation issues is nearly always in the mode of ‘[Beloved Animal] Threatened With Extinction’. That makes for electrifying headlines, but it misdirects concern. The loss of whole species is not the leading problem in conservation. The leading problem is the decline in wild animal populations, sometimes to a radical degree, often diminishing the health of whole ecosystems.

Viewing every conservation issue through the lens of extinction threat is simplistic and usually irrelevant. Worse, it introduces an emotional charge that makes the problem seem cosmic and overwhelming rather than local and solvable. It’s as if the entire field of human medicine were treated solely as a matter of death prevention. Every session with a doctor would begin: ‘Well, you’re dying. Let’s see if we can do anything to slow that down a little.’

Medicine is about health. So is conservation. And as with medicine, the trends for conservation in this century are looking bright. We are re-enriching some ecosystems we once depleted and slowing the depletion of others. Before I explain how we are doing that, let me spell out how exaggerated the focus on extinction has become and how it distorts the public perception of conservation.

Many now assume that we are in the midst of a human-caused ‘Sixth Mass Extinction’ to rival the one that killed off the dinosaurs 66 million years ago. But we’re not. The five historic mass extinctions eliminated 70 per cent or more of all species in a relatively short time. That is not going on now. ‘If all currently threatened species were to go extinct in a few centuries and that rate continued,’ began a recent Nature magazine introduction to a survey of wildlife losses, ‘the sixth mass extinction could come in a couple of centuries or a few millennia.’

Exelon-backed bill seeks $2 more a month for nuclear plants

By Ray Long

Chicago Tribune
Critics of Exelon-backed legislation question why firm deserves consumer help.

Electricity users would have to dip into their pockets a little more to help cover costs of Exelon’s nuclear power plants under legislation unveiled Thursday that the influential corporation maintained would save jobs and keep service steady and reliable.

Exelon is backing the proposal because it could prop up what the company says are three money-losing nuclear plants that produce relatively clean energy compared with other sources of power.

Opponents question whether Exelon would get an unnecessary bailout when a trio of its other nuclear plants are in the black, and supporters of a separate bill prefer a broader approach that would build up renewable resources.

Where the state ends up on the issue will play out in the months ahead as the spring session unfolds, with companies like Exelon wielding clout at the Capitol through campaign contributions to lawmakers.

The Exelon legislation comes out of a joint report rolled out last month by multiple state agencies charged with examining the impact of closing nuclear plants and potential ways to keep them open.

Going To Mars – Why it will never happen

Posted on by

So see if you can follow me on this. Some people see “space travel” as a way to get off this planet. But why would you want to do that? It is a perfectly good planet. I think it is because everyone knows deep down that the way we are treating this planet may ultimately cause its demise. That is why I am ultimately an environmentalist; because I do not believe we can get off this planet. So we humans better change our ways. Why do I believe there will be no space travel for humans. The radiation levels of outer space are too great, the distances too far, and the physical demands too great. Thus I believe in saving energy and creating green energy because I believe it is the only way for our planet to survive. Yet people dream.

Breakthrough in energy harvesting could power life on Mars

Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to research pioneered at Northumbria University, Newcastle.  The technique, which has been proven for the first time by researchers at Northumbria, has been published in the prestigious journal Nature Communications.

The research proposes a new kind of engine for producing energy based on the Leidenfrost effect – a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point. This effect is commonly seen in the way water appears to skitter across the surface of a hot pan, but it also applies to solid carbon dioxide, commonly known as dry ice. Blocks of dry ice are able to levitate above hot surfaces protected by a barrier of evaporated gas vapour. Northumbria’s research proposes using the vapour created by this effect to power an engine. This is the first time the Leidenfrost effect has been adapted as a way of harvesting energy.

The technique has exciting implications for working in extreme and alien environments, such as , where it could be used to make long-term exploration and colonisation sustainable by using naturally occurring solid as a resource rather than a waste product. If this could be realized, then future missions to Mars, such as those in the news recently, may not need to be ‘one-way’ after all.

Kitchen

August 5, 2012

There are a variety of ways to improve the energy efficiency of your kitchen, starting with the way you use your appliances to home sealing and replacing your light fixtures.

Floor Vents/Radiators

  • Ensure vent connections and registers are well sealed at floors, walls and ceilings, which are all common areas for disconnected ducts and leakage.
  • Make sure all floor vents and air registers are clear of furniture, allowing air to flow freely.
  • Install heat resistant reflectors between radiators and walls to reflect heat back into the room instead of onto walls.

Range

  • Use the right sized pots with stove burners; for example, a 6? pot on an 8? burner wastes over 40% of the heat generated.
  • Cover pots and pans when cooking to keep heat in.
  • Learn more:
    • Save up to $36 annually on electric ranges or $18 on gas by simply using the right sized pots on burners.
    • Cook more efficiently and keep your kitchen cooler by covering pots and pans.
    • Keep gas range burners clean to ensure maximum efficiency.

Range Hood

  • Install ENERGY STAR certified range hoods to control moisture and remove cooking odors.
  • Learn more:
    • On average, ENERGY STAR certified ventilation fans use 60% less energy than standard models.
    • Save more than $60 in electricity costs over the life of a fan by replacing it with an ENERGY STAR certified one.
    • By using high performance motors and improved blade design, ENERGY STAR certified fans are quieter, perform better and are longer lasting than standard models.
    • Look for ENERGY STAR certified range hoods at home improvement and hardware stores, or ask for them from your HVAC or electrical contractor.

When I Was Growing Up The Hot Things Were Compact Flourescents

Posted on by

Now the hottest things in the energy conservation world  or at least in the lighting world are LED lights. They come in all shapes and sizes. In fact I have one that I use as a flashlight, but it was intended to be a safety head light for my bicycle. It has been amazingly helpful. This is a complex subject so it will take me a few weeks to get it all posted. But here is a start.

http://en.wikipedia.org/wiki/Light-emitting_diode

Light-emitting diode

From Wikipedia, the free encyclopedia

 

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated.[6] When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.[7]

Appearing as practical electronic components in 1962,[8] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks.

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, and camera flashes. However, LEDs powerful enough for room lighting are still relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology.

Blankenship Pleads Not Guilty to Charges Linked to Massey Mine Explosion

By Jef Feeley and Margaret Cronin Fisk | November 21, 2014

Former Massey Energy chief Donald Blankenship pleaded not guilty to charges linked to the West Virginia mine explosion that killed 29 workers in the worst U.S. coal industry disaster in almost 40 years.

The former executive, 64, once a powerful figure in the coal industry and state politics, wore a gray business as he stood with four lawyers in federal court in Beckley, West Virginia, and said, “Not guilty.”

Blankenship is accused of hampering regulators’ safety inspections of the Upper Big Branch mine in Raleigh County where the explosion occurred in April 2010.

The judge set a trial for Jan. 26. About 50 spectators were in the courtroom.

If the former chief executive officer is convicted of the four charges, he faces a maximum penalty of 31 years in prison, according to prosecutors.

Blankenship is accused of setting hyper-aggressive coal- production quotas and instructing subordinates to ignore basic safety measures, such as controlling explosive coal dust and providing proper ventilation in the mines

But had I read this article before dealing with the problem in my basement I would have known to go straight for the water sources and not messed around with the other stuff I put outside on the porch or on the compost pile. But getting rid of that stuff did not hurt. I mean pancake mix that is two years old. Plant dubris that is months old and could act as food for the midges. So the energy saved in this case is MINE and that is important too.

BIOLOGY AND CONTROL OF NON-BITING AQUATIC MIDGES

By: Charles Apperson, Michael Waldvogel and Stephen Bambara, Extension Entomology
Insect Note – ENT/rsc-15
Non-biting midge flies or chironomids commonly occur in inland and coastal natural and man-made bodies of water. These midges are commonly known as “blind mosquitoes” because they are mosquito-like but do not bite. Midges are also called “fuzzy bills” because of the male’s bushy antennae. These aquatic insects are tolerant of a wide range of environmental conditions. Chironomid midges are found in swift moving streams, deep slow moving rivers, stagnant ditches, and in lakes and ponds that are rich in decomposing organic matter. The presence of certain chironomid midges is often used as an indicator of water quality.Bodies of water in urban and suburban areas are subjected to intensive human use through residential, recreational and agricultural activities. Through runoff, these ponds and lakes often become exceedingly rich in nutrients. Consequently, the variety of organisms in such habitats is usually low with just a few pollution tolerant species developing large populations. Some species of chironomid midges that are tolerant of low dissolved oxygen conditions often are a major component of the bottom invertebrate organisms of urban and suburban lakes, ponds and storm water retention ponds.
BENEFICIAL ASPECTS
Most species of chironomid midges are highly desirable organisms in aquatic habitats. Midges are an important food source for fish and predatory aquatic insects. Larvae “clean” the aquatic environment by consuming and recycling organic debris
