New technology usually evolves as follows:

1. Laboratory
2. Land
3. Sea
4. Air
5. Space

Give it time.

As if turbine aircraft are not outrageously expensive as it stands, hard to see the cost case for going nuclear. We've had nuclear vehicles since the 50's in submarines, it only makes sense if the vehicle can't access other fuels easily. Just because a patent app is put in does not mean they are very serious about it- Airbus just patented an airplane with a windowless cockpit and there are tons of other far-out patents in the system.

There's no comparison between the 1950's tech and the technology breakthrough by Lockheed.

One of the technologies was the direct to electricity without the need for a steam conversion. Electric airplanes would be a wonderful thing.

Again, I do not expect it in the near future. You'd first see it on electrical power plants, then ships (first military then civie), then special use aircraft.

Then more exotic applications.
