Antigravitational devices developed by a computer geek could eventually change the world as we know it.
Or they may just blow a few holes into some barn roofs.
The devices are known as “lifters.” When charged with a small amount of electrical power, they levitate, apparently able to resist Earth’s gravitational forces.
Currently, the devices can only levitate themselves. But developer Tim Ventura and others are working to convert electrical current into a force that can lift and move planes, trains and rocket ships. If that proves possible, the technology that powers lifters could extend the ability to explore space and drastically cut the use of fossil fuels on Earth.
