A suggestion that was made 15 years ago by Tom Jolly.

NewMars discussion thread about it.

Atomic Rockets section on the Solar Moth STR system.

How fast could a solar thermal rocket airship, using water, reach before it enters the night? 3 km/s, perhaps (accelerating at 1 m/s^2 for 4500km)? Enough to be useful as a first stage. A first stage that runs off sunlight and water, both of which can be got for free, or nearly so (you should probably filter the water first...). After it's launched the second stage, fuel it up and use a conventional propeller to fly it back to the launch station.

How low could we get the cost to orbit, particularly for bulk goods like water which don't need special handling?

Its an interesting idea of the solar thermal rocket. I wonder how he got on with the experiments. On the Nuclear thermal front NASA is sticking $18.8 Million into new research on that front.
