The Unique Autosports pool table from Hurricane Billiards looks like it might transform from a pool table to a car, to a robot. It sits on a row of four wheels, yet is perfectly stable. Perfect for the upscale garage, it goes well with beer and pin-up calendars.

Rest assured, it’s priced for those who aren’t affected by such things as the economy. It will likely cost you tens of thousands of dollars. Now, if those wheels helped it to move itself wherever you wanted it, then we’d have something.

Here’s one hell of a conceptual design: the Cadillac World Thorium Fuel concept. Otherwise known as the Cadillac WTF. It was created by Loren Kulesus. Everything about the aptly named WTF has been created to last for 100 years without maintenance. That’s the reason for the element number ninety, thorium: to act as a nuclear fuel powering batteries that would power this beast.

Also, every major system is redundant just in case of a failure. Even the wheels are covered and shouldn’t give you much trouble. The wheels don’t have individual tires. In fact, what you get is one combined unit made up of six individual wheels. That gives you 24 wheels in all, and each wheel has its own induction motor just for good measure. According to the creator, “The vehicle would require the tires to be adjusted every five years, but no material would need to be added or subtracted.”
