A small, lightweight EV is quite practical with present technology. but the expectations of the average potential buyer of same are not practical at all. Detroit and others are caught in that dilemna, trying to achieve the impossible, that is, to create an EV that perfectly supplants present day cars. Can't be done now. We could compromise on cost, range, weight, luxury, performance, size, etc., but compromise is not in the spoiled public's vocabulary.

Until the general public gets the real picture, the WHOLE picture, I don't see the EV hitting mainstream. So, as usual, we will have garage tinkerers like myself leading the way, if/when EVs make any impression. All manufacturers can do is mass produce what is demanded on a scale large enough to cost-justify tooling up. The car companies are all hurting for money now, so they don't have cash to throw at a non-starter like EVs for the general public.

Maybe Government Motors will decree EVs for everyone, and sink a boatload of my great grandkids cash into this?

$this->bbcode_second_pass_quote('patience', 'A') small, lightweight EV is quite practical with present technology. but the expectations of the average potential buyer of same are not practical at all. Detroit and others are caught in that dilemna, trying to achieve the impossible, that is, to create an EV that perfectly supplants present day cars. Can't be done now.

On the contrary, the automakers could address the issue of aerodynamics, and there would be no compromise. The only problem is, they want to sell a car with a 0.30 Cd, then a 0.28, then a 0.25, and so on and so forth drag coefficient before selling a car with a 0.16 drag coefficient. Planned obsolescence has got to be done away with for this to work, and GM and their ilk are not going to let that model go.

80 mpg midsize cars with no compromises were possible more than 10 years ago and with addressing aerodynamics, a midsize EV car that reliably can obtain 100+ miles range on the highway using a 1,000 lb pack of lead acid batteries is certainly doable. High school students and hobbyists have already built EVs with 120-140 mile ranges using lead acid golf cart batteries, and they don't have the best possible drag coefficient that a ground-up car could have nor the resources of the major automakers.

Then there's the large-format NiMH battery; it has longevity measurable in decades, twice the energy density of lead acid, and in volume, would be comparable in per kWh cost to Li Ion. The Toyota RAV4 EV, using a 26 kWh pack, could go more than 100 miles per charge on the highway; the RAV4 EVs in Southern California Edison's fleet have collectively driven millions of miles with these batteries, with some vehicles having more than 150,000 miles on the odometer with the original battery pack and with the same range and performance the vehicles had when they were new. This chemistry allowed the Solectria Sunrise midsize sedan to go 373 miles per charge in the 1997 Tour De Sol using batteries with half the density of today's Li Ion; James Worden, the designer, claimed $20k in mass production for the Sunrise, but the major automakers refused to touch it.

Viable, long range EVs, are so 15 years ago...

$this->bbcode_second_pass_quote('', 'U')ntil the general public gets the real picture, the WHOLE picture, I don't see the EV hitting mainstream.


If the general public would buy a Ford Focus or a Toyota Corolla, then I see little reason why they would reject a Solectria Sunrise or perhaps an electrified version of GM's Precept. With streamlining, the range of an EV on the highway is effectively doubled, per unit of battery weight, over a normal car without the consumer making any sacrifices to get it. The current cars on the market have all the same styling cues a streamlined car would have, but without actually having the streamlining done to them... even the second generation Toyota Prius had a drag coefficient about matching the 1921 Rumpler Tropfenwagen and the Cd of a 2007 Prius is still 30% higher than that of the 1935 Tatra T77a.

The auto industry is embarassingly behind the times, and it is intentional on their part.

Streamlining our auto fleet could give us a 35-40 mpg highway V8 Chevrolet Camaro, or a 50 mpg highway V6 Toyota Camry, with no other changes.

$this->bbcode_second_pass_quote('', 'M')aybe Government Motors will decree EVs for everyone, and sink a boatload of my great grandkids cash into this?


Doubtful; they're still wasting PR effort on the Volt, which IMO, was a very bad idea from the start. PHEVs need a battery that lasts thousands of cycles to be viable, due to their short range. Current Li Ion batteries last about 500 cycles, which would be viable for a 250 mile range EV, but not viable for a 40 mile range PHEV.

The technology to make a Li Ion battery last 3,000+ cycles is *very* expensive even in volume(take a look at the prices of the Li Ion batteries used in DeWatt power tools), while a 500 cycle battery would be affordable to middle class new car buyers if the car is produced in volume.

It seems to me the Volt is part of a greenwashing campaign to take critiscism off of GM. The engineers were given such narrow constraints to design the car with(netting a drag coefficient similar to a Prius, which is about matched by a 1921 Rumpler...). Cars are supposed to be designed by the engineers, not the accountants and PR groupies, and even after its death, GM still hasn't learned this.

Toecutter, you've got to stop looking at aerodynamics as a panacea every time the EV debate comes up. The Cd of a prius or next-gen insight is nothing to be ashamed of. The Precept, Loremo, 1970s Citroens, Aptera, First-gen Insight, EV1, they all have some combination of long fishtail fastbacks, only 2-seat capacity, or fender skirts. Aerodynamics at that level starts to really impact aesthetics and alienate customers. Maybe taste will take a backseat to economy when gas is 2-3X what it is today and companies like Aptera will reap the rewards, but vehicles like the first gen Insight tanked in the marketplace due to factors like these. Not only that, but in stop and go driving or low speed driving, aerodynamics doesn't do squat. Batteries are the key to EVs more than aerodynamics. Look at the range of the Tesla which doesn't even have that great aerodynamics, or the Rav4EV that ran on now old-tech NiMH. If we actually get batteries to come down in price or up the energy capacity then aerodynamics is no longer make or break.

GM hasn't been unduly influenced by engineering at least since the mid 1970's, that I personally experienced. The Board is made up of all money people, and it is a top-down organization. If an employee does not think so, they will be quickly enlightened. Read John DeLorean's old book, "On a Clear Day You Can See General Motors, for insight into how and when the accountants took over the boardroom from the car people. Been going downhill since then, but as I posted elsewhere, it took them about 30 years to squander all the money they had and all they could borrow. No sympathy for them on my part.

Yeah, planned obsolescence is the business model, along with selling all the BS accessories that the market will bear, and do it by attacking the self esteem of the customer, like they do with toothpaste and other toiletries, clothes, on and on. See Vance Packard's old book, "The Status Seekers", about marketing to blue collar people.

Personally, I want to drive something that has better survivability than a "Smartcar", and don't relish the idea of being in a crash with several gallons of sulfuric acid, either. I'll take my bike, before that, the least crashworthy of all.

$this->bbcode_second_pass_quote('Novus', 'D')etroit could only save itself if they can make a fuel efficient auto's or electric cars that don't cost $50,000+.


Even if Detroit had cheap, fuel-efficient cars people wouldn't buy them right now. People have stopped buying the hybrids now that oil is cheap again. Check out the actual numbers........sales of the Prius have collapsed worse then the sales of other kinds of cars.

If GM and Chrysler (and their government overlords) have any brains, they'll put together line-ups of cars that go from small to SUV-size, to maximize sales and profits. As oil prices go higher, people will shift voluntarily to the smaller cars.

Exactly right.....and its going to get worse. The next generation of GM cars will be 100% funded by the government......that means those cars will be designed by the auto geniuses in the Obama administration and Congress.

Detroit: Bike Among the Ruins

Unread postby Ache » Mon 06 Jul 2009, 20:47:20

NYTimes
$this->bbcode_second_pass_quote('', 'O')ne night a little over a year ago, crossing Woodward Avenue, I crashed my bicycle. As I flew head over heels across Detroit’s main boulevard, I thought, well, in any other town, I’d be hitting a car right about now. But this being the Motor City, the street was deserted, completely motor-free.

While bike enthusiasts in most urban areas continue to have to fight for their place on the streets, Detroit has the potential to become a new bicycle utopia. It’s a town just waiting to be taken. With well less than half its peak population, and free of anything resembling a hill, the city and its miles and miles of streets lie open and empty, beckoning. And lately, whether it’s because of the economy or the price of gas or just because it’s a nice thing to do, there are a lot more bikers out riding.

Stirling engine solar dish farms seek to restart Detroit

Unread postby Graeme » Tue 14 Jul 2009, 21:45:28

Stirling engine solar dish farms also seek to restart Detroit

$this->bbcode_second_pass_quote('', 'T')he solar power industry could help put Detroit back to work, according to Sandia National Laboratories and their commercial collaborators who plan to break ground next year on the first commercial Stirling engine-based solar energy collectors. The automotive supply chain can be used to make the collectors.

"Our engines and mirrors are being manufactured and assembled in the United States by what is essentially the existing automotive supply chain," said Sean Gallagher, a vice president at Tessera Solar and Stirling Energy Systems. "This is something that Detroit knows how to do very well. When we get into volume production, this emerging industry will be put our automobile workers back to work."

Tessera Solar (Houston) is constructing two pilot solar dish farms using collectors manufactured by Stirling Energy Systems (SES, Scottsdale, Calif.). The first is a 1,600-megawatt facility for the San Diego California Gas and Electric Utility scheduled to go online in 2010. The second is a Southern California Edison project for a 1,000-megawatt facility in the Mojave Desert to be launched in 2012.

Its a great idea, only it's somehting that should have been started like 15 years ago. The future is not one where we use a lot less energy, not the same or more from alternative sources.

I think inventions like this will probably provide some energy to places but it will be very localized whereas the majority of places will do without.

Looks like Detroit took a turn for the worse after GM and Chrysler went bankrupt. No water, or electricity, entire blocks bulldozed, barbwire roadblocks, private military, and mini dictatorships. Sounds like the Gaza strip in Palestine. How long before the people decide life is not worth living and take take up suicide bombing like they did in Gaza.
