My estimate: only 50 kg of this ice is enough .. every 100 km ... to maintain Tesla's driving parameters .. Refueling time approx. 5 seconds ... besides, such an engine is an eternal life time, well, it is an ordinary semiconductor that will last 100 years ... (like a transistor), and Tesla batteries, only 5 years have the maximum capacity ...
Of course, it's super safe, because even if it's something, it's only a puddle of water that will remain
