An interesting story in the London Sunday Times speculates about the effect of Internet shopping and resulting shopping delivery requirements.
I'm not sure I agree with the thesis that Internet shopping is pushing up carbon emissions, there are so many offsetting factors to consider. But I was impressed with the Smith Edison electric vans featured in the story. With a 3500 pound payload, 150 mile range, and 50 m.p.h. top speed, these vehicles could handle a large percentage of the local delivery duties in most countries.
