NASA is working to make a more efficient, electric-powered plane, and the proposed wings for it look like something out of a dream. 18 small engines sit atop the 31-foot wingspan, and work together to lift and propel the plane forward. The wings are part of NASA's Leading Edge Asynchronous Propellers Technology (LEAPTech) project.
The propellers are all electric, powered by lithium iron phosphate batteries. Each propeller can be operated independently at various speeds to optimize power, with all 18 engines providing lift during takeoff.
If this all sounds too good to be true, that's because it is — for now. NASA will ground test the wings over the next several months. During the testing stage, the wings will be...
