I thought Beardy was a real businessman. Sadly, this means either he can't see through the Hyperloop BS, or he knows it will fail but is just in it for the gravy.
240mph is not much faster than Eurostar. Then look at how expensive HS1/HS2 are/were. Then multiply by about 100 for the cost of hyperloop, which if it ever worked would almost certainly have lower capacity.
Where's the business case?
