High Speed Trains

There's an article on the Economist, which, by the way, I haven't read. I am merely using the article as a lead in to this opinion.

And that is, maybe we don't need high speed trains.  Neither for freight, nor for passengers.  You may laugh at this, but it has been done before.  Airships!  The Hindenberg is an infamous example.  But why recommend something that was apparently discredited for all time?  The reason is that an airship doesn't require energy to get up in the air.  And it can move in a direction, even across an ocean.  Therefore, a solar powered airship would require no fossil fuels and could carry freight and passengers.

Here's the good part.  It might even be able to do this fast.  If JP Aerospace can make an airship that can get to orbit, there could be one that could cross the continent or an ocean.  All without using a drop of fossil fuel.  Think about it.

The only reason to make high speed trains is to use electricity as opposed to using fossil fuels.  But trains require a lot of infrastructure.  Airships would not.
