Tired of Friction

I saw something yesterday about a mechanical storage medium that would harness power in a flywheel device and then return it on demand. The cool part was the fact that the flywheel was suspended in a magnetic field so that it never really touched the sides and thus reduced friction significantly. This got me to thinking, why couldn’t you do the same thing for car wheels and their relationship to axles? Simply suspended the tire in an electromagnetic field. Imagine the fuel economy of this type of arrangement. By fuel I’m of course referring to electric cars, as doing something like this for gas cars doesn’t seem practical. Of course if you could go back and retrofit gas cars, that would be a game changer as well.

Date a Fire

Okay not sure exactly how this would work but woke up this morning wondering if there was a way to use a device to quickly map out a fire by carbon dating the room. So you’d set the device on a tripod in the middle of a room and then it would scan the room and determine the age of the burned areas. Then it would send the data to a program to quickly map it out in 3D for fire investigators to look at.

Of course later on the device could be miniaturized to the point that it would be a attachable to someone’s helmet and then display the data in real time on a small heads-up display, like fighter jet pilots have. Sort of a roadmap would be super imposed on the room. I’m guessing different shades of colors to indicate age of burned area.
