Electric 3 wheeler

I remember reading about a fella that took a Geriatric 3 wheel bicycle and up graded it to a 10 speed trike...
he inherited from his grandmother that had recently passed away, and it went to a good home indeed!
... he got the bright idea of putting an electric motor on it to assist him, sense he could not get a licenses to drive a car, it sounded like a good addition...
he wound up putting 3 or 4 car batteries in the rack behind the rider and a small but powerful electric motor using friction drive on the rear tire... simple but very effective
I saw this guy riding around in Reno when we lived there and he indeed went everywhere on it
... I clocked him at 40 to 45mph one time... on a busy street, McCarron blvd.
now most of the Reno basin is fairly flat and I don't recall seeing him out of town... but in order to go where he went he had to have at least a 4 hr capacity of constant run time...
.... that's not shabby for any electric vehicle !
I have seen sense that time cars made by MIT and UCLA that are almost the same thing and the reports are very good indeed... although they changed the wheels to be 2 in front and one in the rear... the idea of light and 3 wheels was prominant throughout the design.
these cars had fiberglass bodies that looked really cool and even had some solar cells on them.... not many but a few dozen.... now they have barn door size 3 wheelers that boast hundreds of solar cells, but they have no capasity to carry on without the sun...
this guys bicycle did... and for that he deserves a honorable mention....because in my mind he out did the fancy ones at MIT and UCLA or where ever they were.... with a fraction of the money they used....
So to me its obvious that it doesn't have to be super HIGH tech.... just getting the right components and not listening to the nay-sayers is the only important part!
