GM has been touting the Volt as it's triumphant entry into green transportation, but 2011 is a long way off and the big three aren't doing so hot and neither is the Volt, it would seem. Meanwhile, Dean Kamen shows off a working Hybrid Electric/Stirling Engine car based off the TH!NK, a car Ford canceled over a half decade ago (and shipped to Norway where they still live on). The full Frontline Documentary, Heat, which is about the current state of energy policy, implementation, and the climate (which is not good!) is online and well worth watching.

So is Who Killed the Electric Car, which you can view in full online apparently.

And a full Stirling Engine writeup (ignore the section on Stirling's curse, it is wikipedia after all) Previously: Stirling Engines in Space!

The Volt is Vapor right now. As things stand, GM is very unlikely to be around in 2011 to release it.

Karmen's car looks interesting, other than the fact that it uses lithium batteries, which means it will rapidly fail in real world conditions -- lithium batteries hate heat, cold and impact. Guess what you get in a car?

The thing that "amuses" me is that Ford is perfectly able to make small and efficient cars that get rave reviews (the Ford Mondeo changed the face of British motoring) and they *refuse* to sell them in the US.

So, well, they deserve to lose. And they're losing. $7.7 *billion* cash disappeared last quarter from F. The rule going into a recession is that you have to hoard cash and spend it frugally to get through the downturn. GM and F are burning it like mad.

There's no easy way to rebuild the auto industry in the United State. But step one is "Allow GM, Ford, and Chrysler to die."

Don't blame union employees for trying to preserve healthcare for themselves whenever possible. We might all have universal already if it weren't for automakers fighting against it in the first place.

That, and the insane crappiness of their non-truck products, fighting against CAFE, and their underhanded role in destroying LA's original public transportation system is all the reason I need to watch them go down without a tear, as I drive away in my nice dependable Toyota.

It's been about 35 years since the energy crisis of the '70s, when the Japanese first turned up and started taking market share like it belonged to them -- which in every meaningful sense, it did. GM and Ford have spent all 35 of those years screaming for the waaahmbulance on the one hand and manipulating government on the other, but the one thing they absolutely would not do is build something that wasn't a huge wallowing shitmobile with a third of the useful life of a Honda. In the real world of business, nobody gets a 35-year reprieve when they blow it. But they did, and they squandered it. Fuck them.

A government bailout would be a hugely inefficient form of welfare, since you'd be propping up a corporation that's spent a third of a century proving it doesn't want to do anything but fail as an indirect and massively expensive way of writing all those paychecks. It'd be cheaper just to hire the laid-off workers to rebuild bridges. Bring on the New, New Deal, and if the CEOs want some, let them learn to pour concrete.

Their business seems to be:
Step 1) Get government bailout.

But I'm not exactly sure why we should bail them out. The auto industry isn't really all that important for the economy, and the current market caps of GM and ford are tiny. What we ought to do is bail out the employees. You could let the companies go bankrupt and put the employees to work doing something else.

I saw a hilarious T.V. add the other day. A dealership was offering 50 shares of GM with any new car purchase. At today's prices, that's about $250 worth.

We could give each GM employee $83,000 cash and it would still cost the government less then bailing out those companies. A more sensible approach would be to hire them to work on infrastructure projects or investing in new companies that could buy off the old assets from F and GM at bargain basement prices.

Actually Quality (Job #1) has gotten pretty good at ford recently (have you driven a ford... lately?). But seriously, despite the fact that it lines up with their 1980s slogans, fords quality has gotten pretty good lately.

One thing you have to keep in mind is that Ford and GM have huge healthcare costs that overseas competitors don't. Something like 1/3rd of the cost of a GM car goes to healthcare costs. Our lack of universal healthcare is a huge drag on the economy.

Oddly enough, that's exactly how Henry Ford ran his business.

If Ford, et al, were to slash wages by half then the majority of Ford's current line up would be 2/3rds the annual wage of their workers and Ford would be selling even fewer cars.

That's assuming failure == death, which seems doubtful on some level. Their manufacturing capabilities probably have some kind of value floor. Under normal circumstances, I'd bet that pieces of GM would get sold off to businesses or investors that's be interested in rebooting the auto business. Obviously these days aren't normal circumstances, though.

The Volt part makes me sad. I drank the Volt kool-aid as soon as it was shown as a concept vehicle. But I just got done watching the Frontline video. Focusing on cap and trade just for a moment (the video was about climate change, after all), proponents claim that new "green jobs" will boost the economy, while opponents claim that higher energy costs will hurt the economy. The problem, it seems, is the lag time. It'll take upwards of 10 years of building new infrastructure to do something like the Pickens Plan, and if caps on carbon emissions are in effect, dirty energy will get pretty expensive until clean energy can pick up the slack.

Other solutions to this problem are welcome, but here's one proposal from the Frontline site that stuck out. The government's all about stimulus checks these days. After the regulatory and oversight costs of the cap and trade system have been taken out, give the rest back (spread evenly) to the taxpayers! Those people who are hurt the most by higher energy costs will end up benefiting the most from these CO2 rebate checks.

One commentator in the program mentioned that investment in wind and solar has stalled because government tax incentives for development in these technologies looks like an EKG chart. Meanwhile, venture capitalists continue to poor money into alternative energy. As soon as cap and trade becomes a reality, business can forecast how much more expensive dirty energy is going to be in the future, and how much more profitable alternative energy is going to be. New businesses, fueled by venture capital, will figure out which energy solutions look the best for themselves. You don't necessarily need congress deciding where the revenue from the CO2 cap and trade should go, deciding which alternative energy research gets funding and which ones don't.

Err, maybe not. I just think getting a CO2 rebate check would be cool.

As things stand, GM is very unlikely to be around in 2011 to release it.

That's what I was thinking four months ago... but really, GM and Ford will most likely be bailed out and/or partially nationalized. How can the U.S. admit that the entire Domestic Auto Industry has failed?

It'll be interesting to see what happens to Chrysler. I was really incredulous when Cerberus took it private-- seemed like a horrible investment at the time and it seems even worse now.

And Chrysler already received a massive bailout back in 1979, which in addition to the invention of the mini-van, propped up the company for 29 years. How many years will the next round of bailouts buy? At what point does the American Taxpayer get tired of propping up a failed business model?

Ford and GM have huge healthcare costs that overseas competitors don't. Something like 1/3rd of the cost of a GM car goes to healthcare costs.

If GM and Ford and Chrysler are not bailed out, they will declare bankrupcy, rendering all current union contracts null and void. Goodbye health care costs!

The thing that "amuses" me is that Ford is perfectly able to make small and efficient cars that get rave reviews (the Ford Mondeo changed the face of British motoring) and they *refuse* to sell them in the US.

Ford is retooling some of their North American plants to produce the "euro" Focus and Fiesta in 2010. There are also plans to bring the Kuga and C-Max here. Hopefully it's not too late.

They did make them available. Nobody really wanted them in the US. And they do offer a fairly equivalent (and cheaper) car even now.

Um, not really. The American Ford Contour and Focus you linked to are only visually similar to the European versions. Totally different designs, in fact. I came very close to purchasing a Focus hatch (no longer sold) a few years ago, but found the design to be totally lacking. Bottom line is either American market research sucks, or American tastes suck. I'm hoping for the former.

And Chrysler already received a massive bailout back in 1979, which in addition to the invention of the mini-van, propped up the company for 29 years. How many years will the next round of bailouts buy? At what point does the American Taxpayer get tired of propping up a failed business model?

The bailout you speak of was a loan. It was repaid to the government early and with interest.

Look, American car companies built gas guzzlers for two reasons: While there was cheap gas they could sell a shitload of them, and there was much more profit built in than they could realize with economy cars. They did so because American corporations in general have traditionally been rewarded when they bring short-term returns to shareholders. That's what really has to change to foster long-term, innovative thinking.

GM has spent hundred of millions of dollars on the Volt - and will certainly spend over a billion by the time it hits showrooms. It's one of the few programs that is not being cut in their current crisis, because it's their highest-priority program. To call if Vaporware is simply uninformed.

No, I call it Vaporware because I seriously doubt the car will see the light of day, and if it does, it'll almost certainly be an entire generation behind cars from Toyota and Honda, who don't have to attempt to reboot the entire company just to get one small car out that doesn't suck.

Futhermore, it'll feel like a cheap, plasticly car, because that's all GM does anymore. This is the company that actually decided to build a real sports sedan in the European model -- the Cadillac CTS-V. The damn thing worked. Went like hell -- like many US cars do, and turned, which many US cars don't. Actually was competitive with things like the Audi S4 and the BMW M5. Cost, oh, upwards of $60K.

Ever been in one? Cheap plastic interior. The seats are nice, that's about it. But the fit and finish in a $60K car -- bearing the luxury mark of the company -- was crap.

That's why US car companies are failing. I understand cheap finishes in cheap compact cars, because the whole point of the damn car is "cheap." But I am continually bemused by the way US cars in the $35K range look and feel cheaper inside than a $16K Honda Civic.

And so on. While I'm clubbing them, let's hear for the Quad 4 engine. Lord of smoke, eater of timing chains, but the vibration would provide a nice massage.

Oh, and the Northstar! Actually, a pretty damn fine powerplant, but it really, really, really didn't like to run slow. You really needed to get it and wind it up on a regular basis, or it would start burning oil. So, where do they put the damn thing? In the big Cadillacs. Nice.

The *only* way GM survives is if we bail it out. I'm not willing to bet several tens of billions of dollars that GM can make the Volt, esp since I don't have bet a dime on Honda trying to build a better version.

The first three cars I owned were GM. I thought they were good cars. I wondered just why everyone kept on about foreign cars. I then got a high-mileage Civic as a rental, and, lo, I was enlightened.

Most of the work for the car is already done. I suspect it will be released even if they go bankrupt in the process, either if the current management stays on or the government takes over.

How is the volt different than the prius?

The volt has a 40 mile range on battery power, while the Prius has like 4. So, even if you could plug in a Prius to recharge it every day, you wouldn't get very far without gas, so you'd still have to use some. For most Americans, a volt will be able to get them off gas entirely.

The volt also has a much smaller engine that only recharges the batteries.

The idea of the Volt is right on track, I agree. But I don't really trust an American automaker to get it right. That may be unfair, and I want to love American-made cars. I was raised in Dayton, OH, a huge GM town. But the American car companies have done a pretty good job of pissing away their reputations. And now that so many foreign-company cars are actually built in the US, it seems to make less difference. If they can prove themselves over time, as the Prius has done (that's what I drive), I might be interested in a second- or third-generation Volt. But color me skeptical.

I just watched Who Killed the Electric Car? yesterday, so I'm inclined to say that GM can go suck an egg for all I care.

One thing that film glosses over is that the initial, pilot EV-1 that the film centers on was a major money-loser for GM; they had already eaten the massive capitalization and production costs as a loss leader, with the expectation of making it up in the future, when the regulatory and tax climate changed and suddenly their plans for it didn't work anymore. As far as not letting the leaseholders (who weren't paying anything remotely resembling its cost) keep it, GM was going to have to eat more costs in servicing them under the lease, in particular replacing the battery.

Honda is trying something similar with their new HFC car -- they're leasing it to selected people for $600/mo, but in fact each one cost about a million to make.

This is not to let GM off the hook -- if they hadn't been taking a government welfare approach and stayed on it, making the Volt would be a piece of cake for them now. But the film isn't entirely forthright about this detail.

First of all three years for the roll out of a totally new platform using new techonlogy is _extremely_ aggressive. Most platform restylings take three years. Second GM has been working on the Volt for much longer. Thank god otherwise it would be a disaster.

wfrgms writes "Where were these fuckers 10, 15, or 20 years ago? Thanks for shoving all those SUVs down our throats for years."

Every major automaker sells a small car. For example every three PT cruisers sold allowed Chrysler to sell a 1 ton truck. Wide swaths of Americans won't buy those cars and many who will won't buy American because of bad experiences 30 years ago. The massive profit on SUVs kept profits flowing. Why do you think Toyota, Honda and Nissan all brought out full size trucks? And Porsche for crying out loud. Who the smeg buys a Porsche truck?!?

(large-scale electricity generation and electric drive together are so much more efficient that there's probably even a CO2 benefit when the electrons come from coal plants, and certainly when you're talking natural gas/nuclear).

You can't be serious!

What efficiency numbers are you using? Gas turbine efficiency is what, less than 60%? Transmission is about 92% efficient, maybe. The coulometric efficiency of Li-ion batteries is said to be an unbelievable 99.9%, but even then the power supply and charger circuitry will drop the charging efficiency to something closer to 90%. And, Li-ion batteries have a very limited lifetime. Efficiency of a really good electric motor and drive train is maybe 70%. So that's 35% efficiency.. just about the same as a car engine, isn't it?

From Plutor's hydraulic hybrids link:

Lately, the EPA has been focusing on hydraulic hybrid delivery trucks, but Kargul says the lab has also built and tested smaller vehicles, too, including one based on a Ford Taurus. Speaking at the recent IFPE Show, Kargul says this 3,800 lb diesel-powered hybrid vehicle chalked up a gas mileage of 85 mpg.

Seriously, why aren't we looking more into these? If this isn't all hype, and they were indeed able to make a Ford Taurus get 85 mpg with no batteries to worry about disposing of later, that seems like a huge win. What is keeping them from racing this into production?

Because this:

That’s not the case in cities, though, where start-stop driving and lower power requirements force engines to run at less efficient conditions. Here, hydraulic hybrids offer a bigger fuel economy edge. Achten makes a similar point. “For the first time, hydraulic hybrids allow better fuel consumption in the city than on the highway.

and this:

the potential to leverage their high-power-density energy storage capabilities for short-term bursts of power that far outstrip the engine’s nominal power. How much power? O’Brien says Hybra Drive’s Hummer H1 conversion uses a 190 hp diesel engine yet can offer short bursts of power up to 600 hp.

make me think I want this in a car right now.
posted by quin at 10:02 AM on November 10, 2008


Fact is, if people wanted to take energy efficiency seriously, the first measure would be to drop highway speed limits like they did in the 70s, and enforce them. It takes 40% more gas to to complete a given trip at 65mph than it takes at 55mph. Speed limits would have as large an impact as any other measure under discussion.

Re hydraulic hybrids..

City garbage trucks spend fully half their time breaking. Delivery trucks probably a little less, but still a huge percentage. Buses spend a lot of time breaking too, but I'd guess it comes down in the 10-20% range. In passenger cars it is far less than for a bus, so I just don't think regenerative breaking comes out as that useful on a car.

Of course if regenerative breaking comes as an almost free bonus, you're still going to do it, as you see on hybrid cars now.

If hydraulic hybrids offer an attractive performance enhancing feature then there might be a business case, which could change things. On the other hand, if you think about the 70% efficiency of that hydraulic battery, unless you intentionally pump the battery, it will normally be empty. Inflated marketing claims don't always make a business case, and giving Hummer drivers bonus horse power at an efficiency price (by pumping the battery artificially) isn't going to make for more efficient transportation.
