recharging electric cars

I am not an engineer or an electronic specialist but I wonder why we cannot use the air pressure in front of the car through a duct in the bonnet to drive an alternator to produce electricity to re charge the battery while we drive. This would need to know the ammount of energy used to decide the capacity of the alternator and it's production of energy.

NZ EV Production Model

I think a standardized EV model, based on a 750kg platform featuring a basic design car with standard options can be organically grown here in New Zealand and sold worldwide for $25,000 or less. The car would have a 100km range and a top speed of 100kmph. We have the technology and expertise to make it happen right now. Agree or disagree?

$35000 for a volt in the us should make it $41000 her, not $85000.More incentive such as a $5000 minimum trade in on a lease to buy deal would be a good start.

Getting the cost of EVs down

Right now the cost of new electric vehicles in NZ is too high. Seems to me the best options for lowering the price are:

1. Do as Renault have done in Europe and unbundle the battery from the capital cost of the vehicle, with the motorist paying a monthly lease cost for the battery. This would shave somewhere around $15K off the capital cost.
2. A council that wants to own the "EV leadership" space in NZ offering a subsidy... more »

Government's role in accelerating EV uptake

Without the NZ government stepping up to bat with far more substantial incentives than the exemption from Road User Charges, EV uptake in NZ will continue at a snail's pace. Meanwhile, we will continue to spend billions of dollars importing fossil fuels, when vehicles could have been fueled with surplus overnight electricity, most of which comes from renewable sources. Agree or disagree?
