I read on a black history site once that a black man...George
Washington Cleveland Jefferson Evans...actually invented a perpetual
motion machine is 1875 but the white man burnt his home lab down in
order to keep this revolutionary device from being invented with the
credit going to an african american.....~:

I would have at least went in and took all his research
materials..working models etc... before lynching him and his family
then burning his house down.

Perpetual motion machines seem like a perfect way to keep black men from
making a living assuming that is your aim!
