Boeing says it doesn’t know how to construct an anti-gravity machine, but three Dearborn, Michigan teenagers did it and plan to enter their craft in the Detroit Science Fair. The lightweight, triangle-shaped craft flies without the aid of fans, jets or an engine.

Luke Duncan, age 16, says they want to find out if their machine is really using anti-gravity or if something else mysterious is going on. “Our main focus is to determine whether this is antigravity or another phenomenon we don’t really know about, like superconductors,” he says.

Michelle Delio writes in wired.com that antigravity devices are being developed that could eventually change the world as we know it. 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.
