8 grams of thorium could replace gasoline in cars

The price of oil is on an upward spiral due to increasing demand and diminishing supplies. Short of finding vast new untapped reserves buried somewhere under out feet,Launch X431 Diagun, we need to find an alternative sooner rather than later.
Unless you have a lot of money to spend on an electric vehicle, everyone who drives a car today relies on oil for the gasoline that keeps it running. Although replacing the petrol engine with a battery and electric motor seems to be where we are heading,Auto electronics Parts, it only really shifts the problem to the power stations rather than the fuel pumps.
There may be another way to power our cars, however, and it would mean never having to refuel you car–be it with gasoline or an electric charge.
Charles Stevens is an inventor and CEO of Laser Power Systems. His idea is to replace the gasoline engine with an electricity generator that doesn’t require a battery. He is proposing the use of the rare earth mineral thorium in conjunction with a laser and mini turbines that easily produce enough electricity to power a vehicle.
Thorium is abundant and radioactive, but much safer to use than an element such as uranium. When thorium is heated it becomes extremely hot and causes heat surges allowing it to be coupled with mini turbines producing steam that can then be used to generate electricity. It also helps that it has a very large liquid range between melting and boiling point.
Combining a laser, radioactive material,ELM 327 Aluminium, and mini-turbines might sound like a complicated alternative solution to filling your gas tank, but there’s one feature that sells it as a great alternative solution.
Stevens has worked out you’d require a 227kg, 250MW thorium engine in order to power a typical road car. Within that system 1 gram of thorium produces the equivalent of 7,500 gallons of gasoline. So if you fit the Thorium engine with 8 grams of Thorium, it will run the vehicle for its entire lifetime without needing to be refueled while all the time not producing any emissions. The engine lasts so long in fact, that it could be taken from one vehicle and used in another as and when they wear out.
The issues to overcome are the radioactivity and the mining of thorium to make this engine possible. Stevens says the radioactivity can easily be contained with aluminium foil. As for the mining, the reserves are there, with 440,000 tons alone in the U.S., we just need the mining facilities to extract it in large enough quantities. With the potential benefits that is sure to happen.
Stevens admits that his biggest hurdle isn’t the thorium and laser aspects of the system, but the mini turbines which have to be made small enough to fit inside a vehicle while generating enough electricity. Even so, Stevens believes he’ll have a working prototype by 2014 and the potential to not only replace, but improve upon the gasoline-powered engines we rely on today.

This probably should be in the Tailgating section, with the other BS. This story is misleading – let’s put it into practical perspective.

Thorium can be used in a nuclear reactor to produce energy, that’s true. But this technology is in its infancy. They are building a first test plant in India, and it is full scale. To fit inside a vehicle you’d need a micro nuclear plant – which doesn’t exist yet. Next, the Thorium produces heat (not rotational force to turn wheels) so you’d need a steam system to interface with the turbine (all of which would also need to be micro sized). Add in radioactive shielding and safety equipment in case the vehicle wrecks. Thorium might not be as dangerous as Uranium but it is still a concern. I doubt that some aluminum foil, as suggested by the article, would satisfy DOT or EPA (let alone thousands of people who think that the “China Syndrome” movie is scientific truth).

You can’t just turn a nuclear reaction on and off like you start and stop a gasoline engine. So don’t expect to get the same driving miles as 7500 gallons of gasoline because your “engine” would be running all of the time, even while you’re not driving. Laser Power Systems hints that its laser could start and stop the Thorium reaction, but even if that’s true you’d still need to wait some time for the steam to build before it could turn the turbine. So don’t expect to jump in the car, start up and take off like you can with a gasoline engine.

I tried Laser Power Systems’ web site to find some explanation of their design, but there is nothing there of substance except for a link to a Wikipedia page about Thorium – that contains general information but doesn’t explain Laser Power Systems’ application. Maybe the paranoid will claim conspiracy, but their mostly blank web site doesn’t instill any confidence. I’m not saying that all of this is impossible, but I sure don’t expect to see it on the streets any time soon.
