POPSVaTech, D.O.E, Russians, collaborators study rare microorganism that produces hydrogenby
pitim Yesterday 9:15 PM So we finally found a clean energy solution ? guess not - no2liberals writes "I’m all for new sources of energy, but one has to look at the downside. The only emission from hydrogen as a fuel is water vapor, which happens to be the single greatest greenhouse gas. Do we really want vehicles and power plants spewing more of the gas that traps 80% of all radiant heat within the first thirty feet of atmosphere?"

POPSPolluter appeasement But unrestricted greenhouse gas emissions are by far the greatest preventable threat to Americans' LLPH. Yet the government spends virtually nothing to fight global warming -- certainly no significant amount of new money has been allocated for this major threat (the Clinton administration tried, but the Gingrich Congress reversed that effort, reducing or zeroing out every program aimed at climate mitigation or even adaptation). Indeed, most conservatives, including John McCain, oppose even continuing existing incentives for carbon-mitigating strategies like solar and wind power. Conservatives in Congress seem likely to strongly oppose any major effort at a legislative solution (see "Anti-science conservatives must be stopped").

POPSInternal World Bank Study: Biofuel Caused Food Crisis The news comes at a critical point in the world's negotiations on biofuels policy. Leaders of the G8 industrialised countries meet next week in Hokkaido, Japan, where they will discuss the food crisis and come under intense lobbying from campaigners calling for a moratorium on the use of plant-derived fuels. It will also put pressure on the British government, which is due to release its own report on the impact of biofuels, the Gallagher Report. The Guardian has previously reported that the British study will state that plant fuels have played a "significant" part in pushing up food prices to record levels. Although it was expected last week, the report has still not been released. The leaked World Bank study disputes that: "Rapid income growth in developing countries has not led to large increases in global grain consumption and was not a major factor responsible for the large price increases."

POPSA Giant Solar Tower Could Power the Future On a sunny day, the air at the top of the tower would be 70 degrees Fahrenheit (20 degrees Celsius), whereas the air in the greenhouse could reach 160 degrees Fahrenheit (70 degrees Celsius). As this hot air escapes up the tower at 34 mph (15 meters per second), it spins 32 turbines that generate up to 200 megawatts of electricity. Even with all this power, the solar tower is less than one tenth as efficient as solar cells in converting the sun's energy into electricity. The advantage for a solar tower is that its materials are much less expensive.

POPSFlatscreen TVs Poison The Environment? It's worth noting that LCDs also consume far less power than old-style cathode ray tubes, so over the lifetime of a television, the environmental impact of an LCD screen might be net positive.

POPSPentagon to EPA: You and What Army? Refuse to clean up If it were a private polluter and not the Pentagon, the EPA would most likely go to court to force compliance, but an executive branch policy prevents federal agencies from suing one another. Other agencies, including NASA and the Department of Energy, have complied with the EPA’s Superfund cleanup orders without protest. This is the second time in a week that it’s been revealed that the EPA’s authority has been ignored by others in the government. The New York Times reported last Wednesday that, when the EPA sent an e-mail to the White House concluding that greenhouse gasses can be regulated by the Clean Air Act, the White House simply refused to open it, successfully getting the EPA to backtrack.
