Well, everyone in the bio-diesel world has been anxiously awaiting the release to the public of these diesel motorcycles (PDF) developed by HDT for the US military. The word was that they would be available for purchase by civilians sometime early this year, but their site does not yet have purchase information. The engineering (some say it was subcontracted to a Japanese company) of the thing clearly shows that Rudolph Diesel was right about his concept and with a little effort (leave it to the military to subsidize the research) we all could be powering ourselves efficiently with renewable and more secure source of energy.
100 mpg on an indestructable all-terrain vehicle that can be dropped in by parachute and run on nonvolatile fuel you can make yourself…what more could you ask for in 2006?
