Re: Why the series hybrid is far superior to the parallel hybrid.
A series hybrid really needs about 5 kWh to allow a decent plug-in range, thus ruling ultracaps out.
More to the point, the new generation of lithium-ion can be cycled thousands of times from 0 to 100% and back in 5 minutes with massive power outputs (eg A123, Altairnano). These were previously the advantages of the ultracapacitor, so it's difficult to see where the advantage of the ultracapacitor now lies and how it can compete on cost or weight with the far superior new LiIon.
