The Plane That Never Leaves the Ground

Regenerative braking is used on most electric cars (My 2011 Leaf has them) it is a great idea to try to recapture the energy spent on getting up to cruising speed. However, to make it work for planes or rockets you would first have to figure out how to recapture the expended energy in a form that could then be reused by the machine. I personally can’t think of any way to ‘brake’ a plane or a rocket in such a way that the recaptured energy is worth the weight cost of the capturing device.

…as Dr. Novella says in the article, there is no way to overcome Newton’s laws. If there was, it won’t emerge as something as pedestrian as a plane that flies without refueling. That would be small potatoes compared to what could be done if the second law of thermodynamics didn’t apply.
