Subject: Electric aeroplane concept described
Date: Thu, 21 Jun 2007 12:19:28 +0100

The use of the stick rather than the carrot to get cryonicists to 
concentrate near a facility has frequently relied on argument about 
governmental interference with the freedom for people to move about their 
planet. Terrorism is one reason this is happening, but worries about the 
environment is another.

describes an aircraft that uses liquid hydrogen to run a fuel cell that 
provides electricity to a superconducting engine that is also kept cold by 
the liquid hydrogen. (I am not sure but doubt that superconducting motors 
generate heat that has to be removed, rather they just need to be kept 
cold.)

Liquid hydrogen is hardly a safe fuel, but the concept does illustrate that 
solutions are being considered and that one is likely to appear before 
everyone is grounded.
