...adopting an impressive array of advanced technologies invented both in Detroit and very far from it. Instead of an internal-combustion engine, for example, the Hy-wire is powered by fuel cells like those used in the orbiting space station. Power is generated by an electrochemical reaction of hydrogen and oxygen that yields as its by-product only heat and H2O. No smelly exhaust, no smog, no greenhouse gases...
Instead of a rearview mirror, there's a camera that projects an image of the road you have traveled, along with such driving data as speed and hydrogen-fuel levels. Because the car is fully programmable, drivers can set their performance preferences. (Brakes: soft or hard? Engine: sporty or fuel conserving...
...heart of the Hy-wire, however, is the aluminum, skateboard-like chassis that runs the length of the vehicle. Nestled within it are the fuel cells, an electric motor, tanks of compressed hydrogen and all the electronics. Because the fiber-glass body is basically a shell, different models can be swapped like cell-phone covers. So you could in theory drive a sports car on the weekends and change it into a minivan to haul the kids to school...
...talk, Schor advocated the sustainable alternatives to materialist culture described in her new book Sustainable Planet: Solutions for the Twenty-first Century. These included, among other things, parking the gas-guzzling SUV in the garage and retreating in one’s electric car (or, her favorite, the hydrogen operated $100,000 BMW 750 class) to a safer place of simplicity and community—a place where one spends less than $100 on holiday celebrations, uses green cleaning products, eats organic foods and celebrates a generally happy and fulfilled life. As Schor’s personal bumper sticker reads...
...What W?thrich did in the early 1980s was to find a way to analyze the signal from something dramatically smaller. It involves a lot of mathematics - measuring the distances between hundreds of pairs of hydrogen atoms in a given molecule and then combining all of the distances to yield a three-dimensional diagram of the molecule?s shape. That lets biologists understand disease and drug proteins in a whole new way; it was W?thrich?s technique, for example that led to an understanding of the detailed structure of prions, which are involved in Mad Cow disease. It has also been...
