Zeuspaul; At first glance it looks good, but the batteries are costly and with driving every day that tekes 30-70% out and then recharges in three years you have 1000 charge/discharge cycles. This is near the limit of many battery types, and beyond some more exotic ones(like silver cells, 100 C/D cycles max) The battery for your vehicle would exceed the car weight, and is just on the edge for flat terrain in a temperate climate where no heating/air conditioning is needed. To push the Lexuses out of driveways you need to match their price performance ratio(or outlaw them, or run out of oil(never)). Hybrids, fuel cells and flywheels stand a good chance of taking 20-30% of the market over the next 20-30 years. It will be harder in San Francisco and Anchorage where hills and weather exert extra loads on the system. Cars can be better insulated to need less heat/cooling in the body and the transparent areas, and tighter fitted to avoid air loss so body heat is retained(watch the window fogging). Note your simple charging station will need to have enough KW HR capacity to recharge you and all the hundreds of others beside you in the 3-8 hour time you leave it there. The sum of these will be quite a bit, same for home. 30HP is 20KW(+,-) at 100% efficiency, so each hour drive will need 20 KW HR plus inefficiencies to replace it. However it is doable, and at say 20 cents per KW HR would cost $4 a day to recharge, and another $1.50 at home for your off peak charger to do it at night. I see fuel cells and flywheels winning here. The fly wheels are very good and getting better. look here and search for flywheels, amazingly good. Best for bigger vehicles, but they have small ones for wheelchairs.llnl.gov The Lawrence Livermore National Lab Bill
