charging overnight is not sufficient? also, the bus company could just swap the batteries

There's a big flaw in this: most urban buses are on the road continuously!  When do they get recharged???  Do they have to swap out a ton or so of batteries every few hours?

@kris oh, one more thing.

Generally speaking, busses are considered as greener than other cars, because many busses already run on natural gas.

@kris, actually, i think that's coming, according to the following WSJ article.

http://online.wsj.com/article/PR-CO-20130627-911454.html

The Los Angeles County Metropolitan Transportation Authority (Metro) Board of Directors approved a contract with BYD Motors for the manufacture and delivery of up to 25 new all-electric buses as part of a $30 million clean air bus technology pilot project.


The contract went to China's BYD.

@mogulman52, thanks for posting the link to the study. Very helpful. Yes, EV may not be for everyone, but it can be well justified for some users.

Electrics Can Do Well For Some

I looked at this in detail several years ago.  I compared several types of small vehicles including gas, hybrids, pure electric and the volt.  The question was payback.  The Leaf did quite well especially for owners who had access to free charging at work.  It is certainly not for everyone but some can do very well with it.  CNG has lower fuel costs but limited fueling options plus it carries at least a 6K price premium.

Correct.  As a general rule, the energy used will be the cheapest available.  Most alternative energy forms have only niche market acceptance because fossil fuels are still overall cheaper.

And how green electric cars are is a good question.  See http://spectrum.ieee.org/energy/renewables/unclean-at-any-speed for an analysis.

As Ed Begley Jr said in Who killed the electric car? (2006): "Electric cars aren't for everybody.  They can only satisfy the driving needs of 90% of Americans."

No, because it's a niche market item.

An electric car makes a lot of sense for short distance, stop and go driving, in a place like NYC where I live.  Beyond that, the equation changes.  Electric cars don't have the distance capabilities gasoline engines have, the charging infrastructure doesn't exist, and you can refill a gas tank a lot faster than you can recharge an electric car's batteries.  If I were someone like Zipcar, I  might consider getting some to rent, but I'm dubious about how many locals might buy one.

And while I expect the technology to improve, I don't ever expect to see an electric 18 wheeler.

I know one guy who owns a Volt, and I'll have to ask him about his reasons and experience.  He's a tech. so I suppose the geek factor was a major reason.

Another question for him will be the impact of charging on his electric bill.

The one thing no one talks about is that a 100% EV uses more fossil fuel than a normal gas powered vehicle. It takes energy to charge your EV up and more than likely that comes from a coal powered electric plant.

The ony reason Honda, GM and FORD et Al. are pushing EVs are because of laws. They are literally giving them away on CA because there is a state law that X% of a company's cars have to be zero emission or they cannot sell regular cars in CA. The EV is not ready for prime time. It is being forced on the public by laws that are impossible to follow except by selling EVs below cost.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
