    An Endangered Human Species

    By Posted on 4.25.2008 5 Comments

    If we don't get our act together in time and we push this planet past its limits, to the point where things get disaster-movie bad, at the very least we can take solace in the fact that we've been there once before. According to new research out of Stanford University, the human species was on the brink of extinction 70,000 years ago due to an extended drought. It shrunk the human population to a number perhaps as low as 2,000.

    I found that there was an eruption a long time ago that killed off the humans until only 10,000 or 1,000 were left. Toba Supervolcano.

    The Ultimate Paper Airplane

    Japan's space agency gave it the OK. A famous astronaut says he'd get involved. They even tested a prototype in a wind tunnel. Still, it does sound nearly too off-the-wall to be true: Japanese scientists have teamed up with origami experts to design a paper airplane that could withstand re-entry and make its way from space back to Earth.

    The Greening of Hydrogen Fuel Cells

    By Posted on 3.28.2008 3 Comments

    One of the technologies being touted as the next great thing for our cars is the hydrogen fuel cell. If youve heard anything about them, its that there are no harmful emissions, the only by-product is pure water, straight from your tailpipe. Of course, thats only part of the story. While it is true that your exhaust will be clean, thats only because hydrogen in a cell is not a source of energy the way gasoline naturally is—its a carrier, like a battery. The energy to be stored in the cell has to come from somewhere else. Right now, the sources are the same as theyve always been, relying heavily on fossil fuels. The emissions are simply moved from your exhaust to a power plant. But what if the hydrogen could be produced with alternative energy sources?
