RE:VWI've been a BLDP shareholder for a while and can only say that their technology is at present only appropriate for use in an urban area and more specifically for busses. The reason their technology has never made it is the refueling problem. In an urban area, the bus simply drops by one of several refueling stations and in a matter of minutes is back running its route. They can't take it on the road, because there's no fuel stations. Not so with our product. Hope that answeres your question.
