Speaking of the Hyperloop reveal, Elon Musk did an interview today about the transport mode with Businessweek. In the Q&A, he answers an essential question:

“Question:

How would you slow down?

Elon Musk:

When you arrive at the destination, there would be another linear electric motor that absorbs your kinetic energy. As it slows you down, you put that energy back into a battery pack, which then provides the source energy for accelerating the next pod and for storing energy for overnight transport.

The solar panels would be laid on top of the tubes. You would store excess energy in battery packs at each station, so you could run 24-7.”
