If you’re not a mad scientist working from you mother’s basement, then you probably have no idea what Thorium is, so let’s clear that out first. As I just recently discovered, Thorium is a radioactive metal. The cool thing about this metal is that it can fuel your car for long periods of time. In fact, if your cat ran on Thorium, you would probably never have to refuel it. Just 8 grams of this stuff can power a car for at least one million miles. That is enough for a lot of trips to the mall, I can tell you that much.
