Natural gas from water crystals

Ice that burns could be a green fossil fuel - environment - 26 March 2009 - New Scientist

Natural gas locked up in water crystals could be a source of enormous amounts of energy – and if a new technology delivers what scientists are claiming, then it could even be emissions-free too.

To the naked eye, clathrate hydrate looks like regular ice. However, while it is made up partly of water, the water molecules are organised into "cages", which trap individual molecules of methane inside them.

Compared to other fossil fuels, methane – also known as natural gas – releases less carbon dioxide per unit of energy generated. Nevertheless, burning it still releases carbon dioxide and thus drives climate change.

However, according to research presented this week at the national meeting of the American Chemical Society, a new method of extracting the methane could effectively make it a carbon-neutral fossil fuel.

Wind Generator for $100 to $150 dollars

/dev/thekevdog - My Homemade Wind Generator

Lately I've been spending a great deal of time working on ways to generate my own electricity. It isn't a necessity for me yet, but someday being electrically self-sufficient could really come in handy. My interest started a while back when I stumbled upon a how-to article on building wind generators from treadmill motors and PVC pipe. It sounded easy enough, so I decided to try and design my own. This particular design can be built for $100-$150 if you are thrifty and can regularly generate 50-250 watts (considerably cheaper than a solar panel of similar power output). Here's how I built it for those of you who are interested...
