"We The People" Have The Ingenuity & The Resources

Wed, 15 Oct 2008 06:26:35 GMT

clipper's remarks: WE HAVE THE POWER. Today, America is under assault from key oil producing states - some of which are radical regimes whose energy prices and policies are systematically undermining our economy, our national security, and the American way of life. We pay a hefty ransom - two billion dollars every day - to the likes of Saudi Arabia, Iran, and Venezuela, among other foreign powers. Americans are sick and tired of our broken energy policy.

WE HAVE THE POWER highlights America's need to adopt our World War II mentality of "Do it all, Do it now" by tapping into all of our abundant energy resources. We owe it to future generations to explore the vast amount of oil and gas in the Outer Continental Shelf, Alaska's Arctic National Wildlife Refuge (ANWR), as well as our other vital energy resources including Hydroelectric Power, Wind Power, Oil Shale, Natural Gas, Gas Hydrates, Hydrogen, BioFuels, Solar Power, Clean Coal and Nuclear Power.

How To Build a House from Straw Bale and Mud

Warning! If you do not want to live in a straw bale house with a living roof and solar panels to power your satellite internet connectivity, DO NOT watch the video over the fold!

Because when you see this video of Nick Moser's straw bale house project, you will not be able to resist making your own natural house. The gorgeous timber framing which sets a spiral patterned layout inspires the craftsperson in you.

In addition to holding out through Hurricane Ike, straw bale homes have received good reviews with respect to withstanding fires. The natural materials result in excellent heating and cooling properties. And the do-it-yourself aspect means you will have a home tailored to your concept of cool house design.

clipper's remarks: when a big ship is raised a few feet by the ocean swell, think how much energy it takes to lift several thousand tonnes.. Now think of that same ship alongside a quay, and a lever extracting that same energy as it lowers the ship back down before the next swell.. Cmon you engineers!

Japanese Man to “Hang 10″ in Pacific Journey with Wave-Powered Boat

How does he do it? With a wave-powered boat. Wave power has been discussed quite a bit recently, with a lot of applications including traditional grid energy generation. However, Kenichi is taking things to the next level by powering his ocean going vehicle with the very thing it bobs atop.

As you can see in the photo (click for larger view), the boat is powered by two fins that raise and lower with the tide, which drive the propellers. On board energy is provided by solar panels and the boat is primarily made out of recycled aluminum.

By sailing from Japan to Hawai’i, Kenichi and his Suntory Mermaid II hope to set a Guinness World Record for the longest distance traveled in this type of wave-powered ocean goer. To be sure, this boat doesn’t go very fast (it’s got about half of the speed potential of a diesel powered craft), but this type of innovation is certainly interesting to see.

Which Clean Fuel Will Drive Your Future Car?

Mon, 13 Oct 2008 08:07:52 GMT

clipped by: jimmy123
clipper's remarks: The ideal clean fuel for future cars will be affordable, easily available, and will produce zero CO2 emissions into the environment. So why not pick a clean fuel and develop it to the nth degree? Sounds simple enough. Unfortunately, it’s as complicated as a Chinese puzzle. We need fossil fuels to produce the clean fuel that allows us to use an alternative fueled future car. There are clean fuels like electricity with zero CO2 emissions, but the majority of electricity is produced at power plants that use fossil fuels.

In the pageant of competing clean fuel, synthetic fuels come in last place. Although only slightly better than fossil fuels, they may work as a transition fuel since they can be blended with gas or diesel to produce lower levels of pollutants. With gas pipelines already in the ground, another transition fuel is natural gas. Both natural gas and Liquid Petroleum Gas (LPG) produce fewer emissions and are clean-burning fuels that don’t threaten soils or ground or surface water. Biogas is another semi-clean fuel that can be blended with hydrogen to create fewer emissions. Ultra-low Sulfur Diesel (ULSD) can be blended with biodiesel to reduce emissions, but burning 100% biodiesel may release excess nitrogen oxides, and fossil fuels are used in the production process.

Now, in a staid Bay Area office park, a converted hard-drive factory with a shiny new façade has begun churning out unconventional solar tubes that could change the economics of solar power.

The highly-automated factory belongs to Solyndra, a three-year-old company that has received $600 million in venture capital and $1.2 billion in orders for its new modules, which look like curtain rods. Those big investors are betting the company's unique product will soon blanket commercial buildings across the world.

Instead of the standard panels mounted on racks that have dominated solar for the last 20 years, Solyndra's cylindrical solar modules collect sunlight more efficiently across a broader range of angles and catch light reflected off the roof itself. The solar cells also contain no silicon, which has been a costly component of most solar systems.

SkyFuel heats up solar thermal power race

Even with the teetering economy, solar companies are bullish that tapping free energy from the sun is a solid financial move.

SkyFuel, a company spun out of the National Renewable Energy Laboratory (NREL), on Friday is hosting an event to unveil its solar power plant system: a parabolic trough made from reflective plastic. Colorado Gov. Bill Rittner will speak at the event, held at SkyFuel's research center in Arvada, Colo.

Located in a country that relies heavily on coal power to support a population nearing 1.5 billion, CSET’s sustainable attributes are are vigorous as its environmental curriculum. The building is powered by a large array of photovoltaic cells and geothermal energy (which cools and heats the five story floor slabs). Any additional energy collected is stored in batteries that can provide up to two week’s worth of electricity for sunless days.

CSET’s double-glass skin reduces solar radiation, and the large rooftop opening creates natural ventilation while allowing daylight to illuminate the interior spaces. The building also makes extensive use of locally sourced materials in its construction and boasts an onsite rain and gray-water recycling center.

Huge Solar Thermal Power Plant
The Army will be joining with an unnamed private sector partner to build a 500 MW solar thermal power plant at Fort Irwin, California. The plant will supply both power to the public electric grid as well as the base itself. The Army is touting the project as providing greater energy security in the event of a disruption to the power supply at large.

Other Green Efforts
The solar thermal power plant is the obvious big news, but three other green projects were announced concurrently:

The Army is pursuing the purchase of 4,000 small Neighborhood Electric Vehicles to replace gasoline-powered vehicles traditionally used by maintenance and operations staff for use on its posts

Six Army posts have been selected as sites for biomass to fuel demonstrations

The Army will enter into a pilot energy savings performance contract with the private sector

US researchers have found a way to make efficient silicon-based solar cells that are flexible enough to be rolled around a pencil and transparent enough to be used to tint windows on buildings or cars.

The finding, published in the journal Nature Materials, offers a new way to process conventional silicon by slicing the brittle wafers into ultrathin bits and carefully transferring them onto a flexible surface.

"We can make it thin enough that we can put it on plastic to make a rollable system. You can make it grey in the form of a film that could be added to architectural glass," says Professor John Rogers of the University of Illinois at Urbana-Champaign, who led the research.

"It opens up spaces on the fronts of buildings as opportunities for solar energy."

Solar cells, which convert solar energy into electricity, are in high demand because of higher oil prices and concerns over climate change.

Rogers says his technology uses conventional single crystal silicon.

The hottest tech job in America: Wildlife biologist

The hottest tech job in America

Giant solar plants are being built where dozens of protected species live. That’s good news for wildlife biologists.

(Fortune Magazine) — It looks like a scene from an old episode of The X-Files: As a red-tailed hawk circles overhead and a wild pronghorn sheep grazes in the distance, a dozen people in dark sunglasses move methodically through a vast field of golden barley, eyes fixed to the ground, GPS devices in hand. They’re searching for bodies.

In this case, however, the bodies belong to the endangered blunt-nosed leopard lizard, and the crew moving through the knee-high grain are wildlife biologists hired by Ausra, a Silicon Valley startup that’s building a solar power plant for utility PG&E on this square mile of central California ranchland.

Google plans 4.4-trillion-dollar green energy plan

San Francisco - Web giant Google unveiled a new national energy plan for the US Wednesday that it said would largely wean the country of fossil fuels by 2030.

The 4.4-trillion-dollar plan was developed by Google's philanthropic arm Google.org, which predicted that the county would reap net savings of 1 trillion dollars over the idea's 22-year term.

The plan called "Clean Energy 2030" was unveiled in an online posting by Jeffery Greenblatt, Google.org's climate and energy- technology manager. It is based on halting the generation of electricity from coal and oil by 2030 and instead relying on power from wind, nuclear and geothermal sources.

It also entails cutting oil use for cars by 40 per cent. It calls for heavy investments in transmission capacity for wind and solar power in the Great Plains and desert Southwest to help cut 88 per cent of fossil fuel use and 95 per cent of carbon-dioxide emissions by 2030.
