I've not contributed much to this thread other than declaring a preference for alcohol fuels and castor based lubes (both renewable sources)

I am generally in favour of electric powered vehicles and did some research in the early '90s for heavy truck systems.

I do feel that they are cashing in on the hype, prestige and euphoria of the TT, for the wrong reasons.

With hind sight, maybe it would have been far better to have arranged for races (could have been several rounds) to be squeezed in and held at one or more of the major short circuits where there would be no road closures, big crowds, normal TV coverage and, best of all, "several" laps could be achieved per race, to really sort out the competition. If the On-board Power Systems allowed it, there could be endurance races with pit stops to see who could change over to fresh battery packs the quickest.

However, since we have inherited a new TT event, I sincerely hope that it does not fail to the embarassment of the manufacturers, organisers and , above all, our riders who have to carry it all through.
