https://www.youtube.com/watch?v=5FrfGdnTXQ8could this be used for transportation, as an effective break?something that kills momentum must be amazing for space travelright now you have to burn towards your destination for the first half of the journey and away from it to slow down again, waste of energybut with this you can go full speed towards a location, turn on the magnet stop and blow up from all the energy transfer
>>16991232Not going to watch your video but answer is almost certainly either no or that it's already used.
>>16991232The brake is not perfect. High speeds and weak magnets/not enough conductive material will still let the magnet hit the plate. The energy from the deceleration turns into heat in the copper and magnet which puts a hard cap on how much energy can be dumped with this, and deceleration of spacecraft is primarily limited by how much acceleration the passengers can withstand for extended periods of time. If you want to decelerate quickly without expending any extra fuel, crashing into a planet will get you from 100 to 0 real fast, and the range of this interaction relative to the speeds of spacecraft means that there is not much meaningful difference.
