Yeah, But are you really satisfied with 500,000 tons to orbit per year? We
will never be able to build a Dyson sphere at that rate, and bring us to a

I know you are pulling my leg, but as I mentioned, the lift rate needs
to rise to 10 million tons per year.  Half a million is just a start.

How could laser skylons possibly launch once every second? It just isn't
enough.


It's not impossible.  Every day 93,000 flights are starting from
approx. 9,000 airports.

86,400 seconds in a day, so there is more than one take off per second.


So, in addition to this unflown launcher, whose designers have failed
previously to deliver something simpler, you are requiring either a doubling of our airport capacity or the cessation of aviation to allow for the launches to support a technology which hasn't been demonstrated in prototype form? 

Why isn't this a loony idea?
