[QUOTE="Abeness"] All I said was it's being tried, jim. The RAND Corporation thought in 1954 that home computers of 2004 would fit within a single room. I don't have the source of the picture/caption I have (probably from something like Popular Science), but the sucker is complete with a large steering wheel (yes, a steering wheel), lots of analog gauges covering a whole wall (yes, gauges!), and a maybe 18" teletype tractor feed printer. It's also got a large TV mounted high on a wall. With the Fortran language, it was expected to be easy to use. Hah hah. Point is that we don't get anywhere unless we try stuff, however far-fetched and unworkable it may seem to some. Fact is that Honda is trying the fuel cell in consumer vehicles. Whether it will ultimately be safe enough for mass use, I dunno, but they're trying it with hydrogen and I'll be interested to see where it goes. I don't think that the project would have gotten as far as it has if the safety issues were insurmountable.[/QUOTE] /please/ read sci.materials abe. pretty please?
