A sea of green

Blazecock Pileon — Tue, 14 Jul 2009 02:33:49 -0800

"Algae is the ultimate biological system using sunlight to capture and convert carbon dioxide into fuel... I came up with a notion to trick algae into pumping more [fuel] out." Craig Venter's Synthetic Genomics partners with ExxonMobil in a $600M project to harvest biofuels from genetically engineered algae. "We have modest goals of replacing the whole petrochemical industry." [previously] "Over the next 20 years, synthetic genomics is going to become the standard for making anything. The chemical industry will depend on it. Hopefully, a large part of the energy industry will depend on it. We really need to find an alternative to taking carbon out of the ground, burning it, and putting it into the atmosphere. That is the single biggest contribution I could make."

Ten new wind turbine designs. Curious, grotesque, sculptural, beautiful, utilitarian.

"Do you live here?"

you just lost the game — Tue, 25 Nov 2008 07:20:52 -0800

Offshore wind farm stirs up a tempest. Lines are being drawn in the battle over a proposed windmill development to be built in Lake Ontario two kilometres out from the Scarborough Bluffs? Is this just another case of NIMBYism? Or are wind farms unreliable, dangerous to migratory birds, and a source of health problems for people who live near them?

Don't be Carbon-emitting?

HE Amb. T. S. L. DuVal — Wed, 01 Oct 2008 20:36:30 -0800

Google, an internet search company, announced a US$ 4.4 trillion proposal for reducing U.S. dependence on fossil fuels by 2030. Google CEO Eric Schmidt, chided political leadership in the U.S. and the rest of the world for not showing initiative on the issue. Google's philanthropic arm, Google.org has already made significant investments in alternative energy solutions (previously) that will naturally tie in to this plan.Google stock has bounded on the news, but is their plan the way to go?

UFO or Solar Car?

mrgrimm — Wed, 10 Sep 2008 10:09:49 -0800

Marcelo da Luz has been attracting a lot of attention with his snazzy solar car. He's hoping to set a new world record by driving the car from Buffalo, NY, to Inuvik, Northwest Territories.

What is the solar potential of your roof

willnot — Thu, 14 Aug 2008 07:22:05 -0800

Have you ever thought about putting solar panels on your roof? Would you like to know how much power you can generate and what it would cost. RoofRay is a fun site that will calculate it for you and then let you know how much it would cost and how many years you'd need to recoup your investment. You enter an address into a version of Google Maps, and then draw where you want to put the array on your preferably southern facing roof.

In Lester R. Brown's new book Plan B 3.0: Mobilizing to Save Civilization (2008, full-text)) - an update to Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble (2006, full-text) - he calls for a war-time mobilization (ch.13) to save global civilization (already showing Early Signs of Decline (ch.6)) from Deteriorating Oil and Food Security (ch.2), Rising Temperatures and Rising Seas (ch.3), Emerging Water Shortages (ch.4), and Natural Systems Under Stress (ch.5)

How Africa's desert sun can bring Europe power

stbalbach — Thu, 13 Dec 2007 06:31:04 -0800

How Africa's desert sun can bring Europe power. A £5bn solar power demonstration project called Desertec is being developed by Trans-Mediterranean Renewable Energy Cooperation (TREC) that would send solar energy northward from African deserts. The goal is in 30 years to provide a significant fraction of Europe's electricity needs.

The Shipyard

treepour — Tue, 15 May 2007 10:06:18 -0800

Founded in Berkeley by artist Jim Mason, The Shipyard, a collaborative industrial arts space constructed from recycled shipping containers, has hosted numerous large-scale projects and events including a Survival Research Labs show, Power Tool Drag Races, gassification experiments and workshops, and various large-scale Burning Man projects such as 2005's Clockworks. Short documentary here (quicktime). However, relations with the city of Berkeley have been consistently tense. Recently, the city shut off the Shipyard's power, to which the Shipyard responded by going off grid. On May 8, Berkeley issued 3-day vacate and abate notice, with which the Shipyard is attempting to comply (auto-playing video).

Note to self: Invest in Algae

tehloki — Wed, 29 Nov 2006 00:25:57 -0800

Petroleum from Pond Scum: Dr. Isaac Berzin, founder of GreenFuel Technologies, is working on a prototype that uses algae to convert power plant emissions into biofuels. Good news: It would only take a bioreactor twice the size of new Jersey to supply the entire US with its petroleum needs.

Row, row, row your car.

HumanCar (note: 6.7mb WMV) row, row, row your car... but it's telling that they show it going downhill, but not up. And will you need 3 friends whenever you need to run to the store? More videos, and information here.

Big-oil's competition?

Nquire — Thu, 20 Jul 2006 13:52:27 -0800

Newsfilter: Spanish firm claims it can make oil from plankton. A Spanish company (Bio Fuel Systems) claimed on Thursday to have developed a method of breeding plankton and turning the marine plants into oil, providing a potentially inexhaustible source of clean fuel.

Water Power

zardoz — Tue, 16 May 2006 19:17:15 -0800

Water Power (embedded video). Inventor creates a hydrogen-powered vehicle that can run completely on water, or rather HHO. This is perhaps nothing new (or is it?), but fasinating nonetheless. Warning: annoying local news reportage.

Pragmatism vs. Ideology

"End of Oil" rebuts Reagan hagiography ? Amidst the din that is the lengthy US media coverage on Ronald Reagan's demise, the BBC reports on the growing acceptance (with oil industry attendance at a recent ASPO conference in Berlin) of the Hubbert Curve Theory which predicts we are now close to or at the peak of World Oil production. (also see Metafilter,October 2002).

Now, the wayback machine : the year is 1980 and the new President, Ronald Reagan, has ordered a solar hot water system, installed by President Carter, torn off the White House roof. Reagan will preceed to gut federal alternative energy subsidies and federal R&D spending on alternative energy technologies to, instead, spend many billions subsidizing oil, coal, and gas production.... Over the next 23 years, the US lost it's role as the World leader in efficiency and alternative energy technologies.

Got power?

ElvisJesus — Mon, 28 Jul 2003 09:29:11 -0800

An alternative means towards alternative energy? Duke Energy in NC is offering its customers an opportunity to vote for alternative energy sources with their wallets starting today. While you are not really buying the Green Power directly, you are in effect subsidizing it. Is this a creative way to Go Green, or just another feel good gesture?

Volkswagon Successfully Tests Its First Hydrogen Fuel Car.

Keyser Soze — Tue, 04 Feb 2003 03:41:04 -0800

Volkswagon Successfully Tests Its First Hydrogen Fuel Car. "The Volkswagen Bora HY.POWER prototype, which does not use a reformer, obtains its energy from on-board hydrogen to create a hydrogen fuel cell-fuel cells generate electricity through a chemical reaction between hydrogen and oxygen. Fuel cells that use hydrogen offer zero emissions and fuel cells that use gas with reformers offer near-zero emissions" Is this the future we were promised? Either way, Drivers Wanted.

Michigan: Land of Alternative energy? "DTE Energy [Detroit Edison] said Monday it has a deal to build and test a hydrogen system capable of generating more than 15,000 kilowatt-hours of electricity. The $3-million test project, funded by DTE and the U.S. Department of Energy, is to be operational in 2005. " Wayne State University is also jumping on the bandwagon. What, if anything, is your town doing (or claiming it will do)?

Drive on air. A new engine design that not only runs on air, but cleans it too.

donkeysuck — Wed, 03 Oct 2001 13:20:47 -0800

Representative Ron Paul: 'It is clear that protecting certain oil interests and our presence in the Persian Gulf help drive the holy war.' This is his speech to the House of Representatives after 9.11 blaming(in part) U.S. foreign policy for the tragedy. Does anyone have any insight into members of the body politic who are pushing for research into environmentally sound alternatives to oil? The U.S. takes pride in being the best at everything, why not be the best at saving our planet and eliminating our blood-ties with OPEC?

holgate — Tue, 03 Apr 2001 20:28:53 -0800

Wind power vs. hot air? Shamelessly purloined from ms. nut: wind farms in the Mojave are being left idle because the power utilities won't upgrade the distribution lines. Instead, they buy in power from neighbouring grids, at inflated prices, with the state and the consumer underwriting the cost. (more inside thread)

Flying Windmills and Whirlygigs. As the windy month comes to a close, these two stories seem appropriate. Two men on opposite sides of the globe, each a bit of a cross between Edison and Quixote.
