Each has something obvious wrong with it.
[/QUOTE]
Untrue. Each has engineering challenges or is currently cost prohibitive when compared to cheap oil. Some are not quite ready for full scale production, some still need heavy research and development. Some have greater or lesser impacts. But afaik there are no show stoppers with any of the alternative techs currently being explored…not even bio-fuels. It’s all about trade-offs of course…but any of the top alternatives COULD replace oil in time, given a wide enough acceptance.
For that matter we could simply stay with oil and develop more fuel efficient cars, develop new reserves (such as tar sands or shale oils), and just live with the consequences of global warming. I think if it comes down to a choice between taking our chances with global warming and the collapse of our society/civilization…I’m guessing we’ll pick door number 1. Obviously YMMV since you seem to see a collapse.

An automobile has a range-before-refueling of at least 200 miles – no sedan-sized electric car yet has anywhere near a 100-mile range-before-recharging and it might be flatly impossible to get past that barrier.
[/QUOTE]
Well, the Tesla does something like 200-230 miles on a charge IIRC. True, it’s not a ‘sedan-sized electric car’…but it’s also targeting the sports car market. There is a lot of development going on toward all electric cars. However, even if they can’t solve the problems of more charge in a lighter battery there are always hybrids. Hydrogen or Methane spring to mind as potential technologies to couple with battery for a hybrid vehicle.
[QUOTE=BrainGlutton]
That alone would make the all-electric car an inadequate replacement for ICE, to say nothing of the fact that recharging a battery takes time.
[/QUOTE]
Maybe so…and maybe no. As I said, there is a lot of development going on in battery technology and it’s hard to say what will or won’t be possible. It’s one of the reasons I don’t want to see the government pour a lot of money at any one technology as we don’t KNOW what will be the optimal solution in the end. I think it’s a pretty good bet though that something will come along to supersede the ICE and burning hydrocarbons.

Hydrogen only works if you have a cheap way to make it in quantity, which would require a lot more nuke plants, good luck with that.
[/QUOTE]
Making hydrogen in quantity isn’t all that hard, and as for cheap…it’s as cheap as whatever we are using for energy. The main drawback to hydrogen I think is it’s corrosive nature and creating a hydrogen infrastructure. Again though, there are no real show stoppers to going to hydrogen…just engineering and logistics. Personally I think hydrogen is definitely in the running for a replacement technology, especially coupled with nuclear power. Or perhaps we’ll use methane instead as there are vast reserves of that world wide (MUCH greater reserves of methane than oil ever had).

Solar-powered cars are still no more than go-karts and probably will never be more.
[/QUOTE]
Again, there is a lot of development going on in solar and some key breakthroughs have been made in recent years in making the cells smaller, lighter and cheaper. Perhaps you would get a hybrid vehicle with printed solar cells embedded in the paint of your car, coupled with high performance battery technology, or a combination of solar, battery and fuel cell. I think you are dismissing these technologies because they aren’t ready for prime time today. Myself, I think any one of these technologies has the potential to be the next personal transport energy source given time and effort. We are on the cusp of several of these technologies being developed enough to produce and actually compete with the rising price of oil.
[QUOTE=BrainGlutton]
The former, perhaps, if we keep going as we’re going and put research and effort only into “solutions” that we hope won’t require any change in our daily lives. (Not actual caves, of course, but perhaps something like the world envisioned here.) The latter if we put our efforts into restructuring our living arrangements, and into rail, which still requires energy and lots of it, but is at least much more energy-efficient than automotive transport.
[/QUOTE]
Well, you can dream I suppose. But IMHO it ain’t gona happen. We won’t be radically restructuring out entire society, we won’t be creating vast HSR systems…and we won’t be moving back into caves. You hand wave away ‘solutions’…but companies are spending billions of dollars on researching and developing those ‘solutions’, and several of them are close to being ready for prime time. There are hundreds of billions of dollars at stake in bringing that new technology to market and becoming the replacement for the ICE/hydrocarbon…and my bet is on people developing that replacement tech, solving the engineering problems and bringing it to market for just that reason.
