[hpv] 2 wheel drive Delta.

>Gentlemen:
In the development of the StormyWeather  velomobile the delta configuration
proved to be the simplest to execute.
Attempts were executed in driving the  left rear wheel, the right  rear wheel
and a complicated freewheel differential on an owner completed Stormy.
One was completed with a FWD  geared hub. Two Stormy velos were built with
delailler FWD and later converted to  RWD left wheel.
      The most recent builds  drive the left rear wheel.
Every solution is some sort of compromise.
   I admit that the differential addresses a theoretical problem that doesn't
really come up on a practical delta.
   The other solution to this perceived problem is to put two wheels infront.
This is referred to as a backward trike or tadpole. The popularity of this
design I struggle to comprehend.
    This opinion is age related.   Not as old as John Tetz , but close.
