Here's and interesting question for you all. Most of you would have heard of the Sinclair C5 electric car. Until this week I owned and ran www.c5alive.co.uk (now sadly moved on because of emmigration plans), anyhow I digress. The legalities of using it in the UK is that it is a 3 wheeled electric tricycle that has a 12v deep discharge battery (12v 36amp/hr) running a 250w 12v motor. Maximum legal speed is 15mph and it has pedals should the battery run flat. One of my customers has simply replaced the battery for a 12v petrol powered generator (in the boot compartment of the machine) So... the generator is producing the required 12v in place of the battery but it is not connected in any direct fashion (ie gearbox etc) Do you think this is arguably legal as a electric vehicle for the above road use ? (I guess you could substitute fuel cell/nuclear power/steam turbine/ wind turbine or any other electricity generating mechanism in place of the petrol generator for arguments sake, but being petrol powered makes it comparatively intreguing) Its of no great importance but an interesting conversation.
