Heavy-Duty Electric Vehicles

A reader writes in:

A lot of acceptable solutions for electric passenger cars (light duty vehicles) were already proposed and I agree that are very viable. Unfortunately for heavy vehicles (interurban buses and trucks) are not so many.

I see this changing quickly, driven in part by government mandates. There are 70,000 diesel container movers operating in the Los Angeles/Long Beach harbor, and the state of California is getting extremely tough on diesel emissions. In response, companies that offer heavy-duty EVs like Balqon are springing up. My consulting company, EV World Associates, happens to have dealings with them. I love their design; 140 kWh battery packs line the sides.
