I agree, Rob. The idea is sensible. I think pure EVs will find a niche, but it won't be at the low end of the market. And it won't be a big niche. Consumer Reports said last week that the Tesla Model S might be the best car they've EVER seen, but it cost $90,000.
The article from this link makes a ton of sense, Chuck. The hybrid car delivers the features needed by average car owners -- practicality, affordability. EVs are far from that. I find it at bit odd that automakers are investing so heavily in EV development.
The article that I read was a description of Edisons development of the battery package for use in our submarines, which I guess he sold the idea to our navy, although I think that they stuck with lead-acid for a while.
Your link lead to another interesting blog,which included comments about the compressed air powered car, and questions about why that has not been developed more. I can explain exactly why, which is that those very high air pressures are very dangerous and no company with any sense at all would put a system with 20,000PSI air, or even just 5000PSI air anyplace where regular people could get at it. And it would certainly take that kind of pressures to store enough energy to drive a car very far. Tata may be able to sell that product in India, but in the USA the tort lawyers would devour them in just a few minutes.
If it continued on the way it's been, Rob, I think EV battery funding would cloud the development of IC engines. Lately, though, I'm hearing more automakers talking about internal combustion engines when it comes to meeting to 2025 CAFE mandate. See the link below:
I wish I could give you a definitive answer to your question, William K, but I can't. I can say, however, that for the past 25-30 years, nickel-iron and lead-acid were pretty equal in terms of specific energy, with both being around 30-50 Wh/kg, depending on the year you looked at them. I started writing articles about electric cars in the late 1980s, and Chrysler was sold on the idea of nickel-iron at that time, but they later backed off. Here's a link to a New York Times article on Edison's battery from November, 1911:
I just re-read an article about the battery that Thomas Edison invented and adapted for use in submarines over a hundred years ago. That is the nickel-iron alkaline battery. I have not done any research on it, but the claimed benefits for submarine applications certainly make it out to be a much better choice for that application. So I am wondering if the power density is that much less than the lead-acid chemistry, or is it a more expensive chemistry that never made it to be a commercial success? Or is there some other reason that I am not aware of?
Good point, theboz808. Incentives for alternative-fuel engines or electric power could cloud the development of a clean-burning internal combustion engine. The automakers are working at it anyway. There are some very efficient IC engines coming out of Ford.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
