The lure of extracting hydrogen from water in a somewhat real-time fashion in sufficient quantities to power an automobile has so far been a complete dead-end pursuit. One of the biggest problems is that it takes more energy to release the hydrogen from its water-tight bonds than is actually returned by the resulting hydrogen.

Green pavement? What's so exciting about that? If I wanted to test out some green pavement, all I'd need to do is make a run to the local Home Depot, pick up a can of green paint and dump it outside my driveway, right? Well, that's not exactly what we're talking about here, of course. But just what is "green pavement" anyway?

We recently heard that, according to one group of researchers at Environmental Science & Technology magazine, corn ethanol has a water cost of 50 gallons per mile. Now, a team working from the University of Twente in the Netherlands has calculated the water cost of ethanol and other biofuels and to make bioelectricity. The results are not pretty. The researchers looked at 13 crops
We've had our share of posts on on-board hydrogen-generating engines over the past few years, and I'm sure there will be many more. The truth is that water engine hype will always need to confront reality from time to time. When it does, the results are not pretty. Coast To Coast AM wasn't fooled, neither was Sebastian Blanco
Many politicians and others have promoted nuclear power as a means of addressing climate change since reactors emit no greenhouse gases or noxious pollutants. Setting aside for the moment the issue of what do with radioactive waste (by no means a trivial issue) there are other issues with nuclear power that will prevent it from being a panacea.
We've already seen corn prices on the rise as demand rises thanks to more of the grain being diverted to ethanol production. As the population of both the United States and the planet continues to rise, the demand for fresh water goes up with it. Unfortunately ethanol production and climate change are both taking an ever larger gulp of the available supply. The recent mild winters in the great lakes region have led to less ice cover and greater evaporation from the Great Lakes. The lakes contain
Voller Energy, a developer and manufacturer of portable fuel-cell systems, has announced that they have successfully assembled and demonstrated the operation of a complete and totally self-contained prototype fuel-cell system which can be run on compressed natural gas (CNG/LPG) or propane. Voller plans to commercialize their 1kW class auxiliary power units (APUs), which includ
