Wasn't project Orion a really bad idea version of this? But I think the fuel scoop was the only missing technology?

I think it was Daedalus that used the scoop. Orion used the pusher plate nukes.

Daedalus was still an Orion-esque engine, but with thermonuclear (not fission) 'devices'.

Bussard ramjets are out of favour as nobody is sure that they make nett thrust.
