    Re: Beneficial environmental/economic ideas

    I've always wondered why they didn't hook up an alternator directly to a turbo 'nStuff... won't help at idle, but what about at cruise?

    @Fluff's compressor question, yes, they can be very efficient. The Honda idea is pretty straight-forward too and provides a relevant comparison. A typical internal combustion engine struggles to hit 40% efficienty. Compressors typically exceed that by far, even when you factor in a motor running in the 90% range. Compressors naturally generate a lot of heat, so unless there is heat recovery going on there you'll take a hit similar to a gas engine.

    FWIW, I think I've settled on a heat source for the new house. 'Ol Al Gore should be proud as it's almost carbon neutral. It's a wood gasification boiler from HS Tarm. Total efficiency is in the 80% range and aside from the juice to blow air and circulate fluid for radiant heating, and a bit of gas for the chainsaw, it's practically free heat if you've got a wood source.

    Now if burying coils for geothermal wasn't so stinking expensive, I might have gone that way and had my cooling done, too.

    I've always thought it would be great to collect rainwater in a roof tank to flush toilets with. Using drinking water to do the same thing is very inneficient. Water is really heavy to move around and then you've got to treat and pump it for miles.

    On the Market: a Whole Rain Forest
    Friday, Mar. 28, 2008 By BRYAN WALSH


    AFP/Getty

    How much is a rain forest worth? Until recently the answer was: virtually nothing. A tropical rain forest provides habitat for untold species of animals and varieties of plants; modulates the climate and helps bring precipitation to land thousands of miles away; sequesters billions upon billions of the greenhouse gas carbon dioxide. But the only market value a forest had were the trees within it, cut down. "Forests fall for a simple reason," says Andrew Mitchell, a conservationist and the founder of the London-based Global Canopy Programme, an umbrella group of forest organizations. "They are worth more dead than alive...

    "It's a bold bet"

    No kidding. I can see the day we'll be getting a bill from some European company for oxygen produced by a South American rain forest.

    Air is no longer free.

    Just like spaceballs where air comes from a can, lol.

    A world where air is taxed and rationed ic likely to happen if things continue the way they are.

    Humanity needs to learn how to be sustainable to ensure its survivability long into the future.

    Algae: 'The ultimate in renewable energy'


    Plant physiologist Glen Kertz believes algae can some day be competitive as a source for biofuel.

    ANTHONY, Texas (CNN) -- Texas may be best known for "Big Oil." But the oil that could some day make a dent in the country's use of fossil fuels is small. Microscopic, in fact: algae. Literally and figuratively, this is green fuel.

    "Algae is the ultimate in renewable energy," Glen Kertz, president and CEO of Valcent Products, told CNN while conducting a tour of his algae greenhouse on the outskirts of El Paso...

    Phil McKenna at NewScientist.com news service describes a nanotechnology advance that turns radiation directly into electricity, leading us to wonder if it thus simultaneously provides a use for nuclear waste. This nanotech application appears to be in the early stages of development, so aside from questions of just how efficient and how expensive it would be, one wonders how resistant this nanomaterial would be to radiation damage. From “Nanomaterial turns radiation directly into electricity“:
