Dmitriy Tseliakhovich talks Escape Dynamics

The same Microwave Beamed Power array could also do double duty powering a Propulsive Fluid Accumulator at the edge of the upper atmosphere when it's not powering spacecraft launches... en.wikipedia.org/wiki/Propulsive_fluid_accumulator

[@miles2378]

does anyone know the status of their endeavor?

[@thorwaldjohanson2526]

Interesting concept. I think It will be very hard to pull off, but we need visionaries. I'm personally betting on Air breathing rocket engines like the SABRE engine.

The flag graphic on the top of the craft is in the wrong orientation. Remember, 'never in retreat'...

[@darkcynite]

I know they want single stage to orbit. I think this might combine well with stratolaunch. You have a big carrier plane haul the launch vehicle up to where your array can target the vehicle easily and you get multiple launch vectors out of one array. I wonder if a denser propellant than hydrogen would work better? I guess it comes down to how much heat they can transmit. Reminds me of the old nuclear thermal rocket research.

Hello , I'm , Gianfranco Fronzi . You say that no idea is too radical and you would like the input , so if you would judge my ideas . I ask , why a craft to access space ? Space is a vacuum , it sucks , all we have to do is add the straw . The Sahara desert is full of sand , silica . Why not use it to build a huge pyramid with a tube in the center . This tube large enough for space cargo . A platform when loaded with cargo acts as a piston that rises due to the negative pressure above . It's accent governed by latches or friction along the tube which at the top is slowed and incapable of ejection uncontrollably . This might sound outlandish but you wanted ideas , this is mine for your topic .

[@thorwaldjohanson2526]

+Gianfranco Fronzi that would not work. imagine a bowl of water. now you put in a straw into that water and create a vacuum above all that. nothing would happen because the pressure (of the water / atmosphere) is nothing else than the fluid pushing downward because of gravity. the water in the straw and outside of it is getting pulled down equally. I hope that was understandable. AND if we could build such a structure, it would be much easier to alter it a bit and use it as an elevator (google space elevator). Greetings from germany :)

[@GianfrancoFronzi]

Thorwald Johanson What you've said works with my idea also .

[@Supadubya]

There's no reason Microwave Beamed Power cannot be combined with spaceplanes (the higher TWR and ISP compared to rockets might be able to make them feasible- and you can also use the beamed power in Thermal Turbojets in the lower atmosphere that operate off microwave-heated Heat Exchangers rather than heavy nuclear reactors), or even orbital blimps (with a series of repeater stations for the microwaves already in orbit). But the rocket version should work perfectly fine- rockets are a proven technology, all this really does in change the propulsion system to something more efficient and require a different ascent trajectory. If you don't understand what any of the terms I just said meant, I *HIGHLY* recommend going an playing Kerbal Space Program (not 100% realistic, but it WILL teach you the real meaning of a lot of rocket science bit-by-bit...)

[@AgzamovAkhror]

Supadubya It makes you to understand the main problem of space travel))

[@Dgfrmxon]

It sounds like there's a lot of research in terms of wireless power transmission, but this is all very far away from being usable on aircraft or rockets. The transmission efficiency isn't the problem. The problem is pushing enough power through the system. Rockets demand literally explosive energies. Transfer by induction at long distances is quite the opposite of this.

[@CommandLineCowboy]

With cheaper access to space, you build solar arrays and HPMW emitters in orbit. In the future, your flying car is powered from orbit. I suppose some reaction mass is needed, if this were a sulphate you'd have the synergy of cheap access to space and reversing global warming.

They're in luck, important breakthrough in MASERS where done not too long ago. Cryogenic electronics no longer needed.
