GM to produce hydrogen cars

General Motors is planning to produce and sell a lot of hybrid cars - in which the burning gas recharges an electric motor. Today, however, GM also signed a $88 million deal with the Department of Energy to build 40 hydrogen fuel cell vehicles and to improve the technology. Shell Hydrogen LLC will provide them with five Hydrogen gas stations across the U.S.
Note that the hydrogen motors are based on this fascinating chemical reaction:
  • 2 H_2 + O_2 -> 2 H_2 O
An amazing feature of this reaction is that it does not involve carbon - the element that has recently been identified by the "progressives" as the ultimate source of evil (such as the so-called global warming as well as life itself). The hydrogen fuel cells have been used by the astronauts from the very beginnings of the space program in the 1960s, and the barriers that have always prevented this technology from spreading to the car industry and elsewhere were always economical in character. It is about 4 times as expensive to produce hydrogen. My friend George has a rather informative description of the situation at the web page of his house:



I can imagine that it will become cheap to produce hydrogen and this clean technology will dominate in 10 years or so. Nevertheless, it is still easier for me to imagine that these projects will remain a fancy and overly expensive demonstration of the hypothetical possibilities - and further progress will be based on conventional motors that produce CO_2.
