I had the same reservation about the "eco" possibilities. And these comments are close to what actually seemed to motivate the guy: he was told by a mechanic doing a routine check that his battery only had 200 cranking amps left and would not start the car in winter. He says he did not want to buy another battery just for that purpose and that got him started on this...
Mazda is using capacitors like this to charge from regen braking really quickly (as they can) and then shut off the alt and trickle the charge into the system (or something like that). Seems to benefit their cars about 2 or 3 mpg.
