You don't need to put it in the gear opposite to the direction it'll roll. Generally you want to put it in the gear with the lowest ratio (which in my car I think is first), as that will require the most amount of force to turn the engine. But also some engines shouldn't be rotated backwards because that might damage them. So that would mean put it in first facing downhill or reverse facing uphill.

They'll test it on the ground and flying slowly first before going fast to make sure it's safe enough.

Some phones can already do that, like wireless powershare (Samsung)
