Hi all,

A pal of mine is hosting one of the TT Zero teams for this year's
competition. This is a race for the newish category of zero-emission
electric bikes. They're developing very rapidly currently and are at
present capable of putting out 160bhp for 37.75 miles (one lap) at least
(on a good day anyway). Some online calculator I've tried states this is
equal to about 120kW but that seems like an awful lot to me and surely
cannot be right. I was just wondering what sort of electric bill he can
expect (after they've gone home, obviously). They made several overnight
charge-ups during testing and he said his breakers were repeatedly
tripping out. Anyone care to do the maths? You'll have to allow for
efficiency as well, of course, since the 160bhp is the power OUT. I'll
pass on the result when I see him again tomorrow (assuming it's not too
horrible, that is, as he has a heart condition).

cheers, cd.
