My little error was that somehow my calculations for rolling resistance factored in velocity - Crr x m x g x v.
It should have been Crr x m x g.
The result is that I only need half the batteries for my electric trike then I thought.:thumbsup:

"Crr x m x g" sounds like the noise you'd make when you realised there was an error!

So, only three and a half thousand AAs then? ;)

Five thousand, eight hundred rechargable AA cells.;)

It will mean I can get the range of 70 miles at 70mph using 23 x 100Ah lithium cells instead of 23 x 200Ah lithium cells with the saving in weight and space as well as money.

Night Train, are you feeling better this week?



It is a very blustery day here today. I was thinking aloud :blush: in the garden about half an hour ago, asking myself (and some particular plants that have multiplied and look a bit crowded) if some of them would like to be in the front garden, with more sun. It was almost as if they were replying, because the wind caught them and they seemed to be nodding their heads as if to say "No!". :blush: :wacko: :unsure:

Your incorrect calculations remind me of the time I crashed the computer system for the whole of the south West of England for a government dept. :blush: :sad: Might tell you about that later. I am going to do some more gardening talk to some more plants. ;)

Do they talk back, Speicher?
They would if they could get a word in.

To go with tea there should always be cake.
