Hi,
My first thought is great idea
if it works, or is it another
free electricity con, I certainly hope it's not silent you won't hear it until you've been squashed quite flat.
If it has to be stripped of all luxuries for weight it seems it will be somewhat slow,will make you feel like you're in a Sinclair C5, dangerous for it's driver, still pulling away after the lights have gone red and the others gone green and there you are, stuck in the middle.
Max.
