DailyDirt: Cars You Can't Buy (Yet?)
from the urls-we-dig-up dept
There are plenty of cool cars that are just too expensive for most people to even think about buying, but sometimes the really cool cars are the ones that aren't even quite ready to be sold (Tesla SUV, anyone?). Gull wing doors and exotic metal alloys are usually the key parts of concept vehicles and prototype cars. Here are just a couple cars you might have seen and a prediction of what we'll all be driving in the next few decades.- In 1957, Ford introduced the Ford Nucleon -- a nuclear-powered concept car that ran on uranium fission instead of any kind of petroleum. Sure, it wouldn't emit any carbon dioxide, but it's not clear how the radioactive waste would be disposed of.... [url]
- The Volkswagen XL1 is almost ready for production as a 2-seater plug-in hybrid that gets about 261 miles per gallon of diesel. If fuel economy is all you want, fuel economy is all you get. [url]
- Shell predicts that petroleum-powered passenger cars will be mostly gone by 2070, replaced by hybrid hydrogen-electric vehicles or other oil-free cars. Or maybe by 2070, we just won't have much reason to drive anywhere? [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Nuke cars -- great idea.

Re: Nuke cars -- great idea.
Even for people with knowledge it might be problematic if the car gets damaged in a traffic accident or just from normal decay of the battery. You can probably do a lot to avoid spills, but then price becomes a problem.
Basically some of the same problems appear in nuclear power plants today even though it is far easier to justify high safety standards when you can produce to a lot of people at the same time and thereby spread the economic burden.

In any case one has to wonder if such changes will come in time to avoid environmental collapse. Here I'm betting they won't. And we can thank the petroleum industry for that.

Nuclear energy and cars
The solution lies in the use of liquid fluoride thorium reactors (LFTRs), a technology developed in the 1960s at Oak Ridge National Laboratory. It uses thorium for fuel, rather than uranium, and does not produce weaponizable byproducts. It runs at normal atmospheric pressure, with the fuel embedded in the coolant. The fuel/coolant mixture is held in the reactor by an actively-cooled freeze plug, so, if power is lost, the plug melts and the fuel/coolant drains out into safe storage areas where it cools and solidifies. (They tested these safety mechanisms at Oak Ridge, too, by literally turning off the power and going home for the weekend!) A Fukushima-type accident is utterly impossible with this design.
The reactor's normal operating temperature is around 600 degrees, which carries two advantages. First, it doesn't need a big source of water for cooling; it can use air-cooled turbines. Second, the reactor's process heat can be used directly, without conversion into electricity, to drive the synthesis of petroleum from any convenient carbon source using the Fischer-Tropsch process (which was being used by the Germans in World War II). So, for instance, you could extract the thorium from coal (which is a natural impurity, and a pollutant that existing coal-burning power plants have to deal with), use that to run LFTRs, and convert the remaining coal into synthetic petroleum that would run existing cars, plus generate electricity (including sufficient electricity to crack water for hydrogen to power cars that way, if you're so inclined). This would allow us to keep from importing foreign oil, with all the geopolitical implications associated with that, and it would even reduce carbon emissions, since we would be "burning" coal as oil, not burning both coal and oil.
As I said, no technological breakthroughs are required. All we lack is the political will to engineer the existing technology for effective commercial use, and start building the reactors.
For more information on LFTRs and associated technology, this is a good place to start.
