    MIT has just shown that volume production of graphene is possible, and that might be the saving grace of this idea. When I ran spreadsheets a few years ago, using a pretty decent atmospheric model, I couldn't get much beyond 100 Km.

    That could still be good enough for a tether pickup.

    Did you consider a helium airship heated by groundbased beams?

    Two hot helium airships with a cargo pod strung out on a tether between them, that could be picked up by an orbital tether.

    The orbital tether would also collect bags of lunar dust to help it maintain orbit by dropping it on Angus when it has been received from an electrical catapult on the moon.

    I almost could have scored a 'half angus' but this thread is already too off-topic to add something intentionally unrelated.

    All that helium three, you will be so rich.

    @Andrew

    How thin is the atmosphere at a hundred K?

    Would ESA air breathing ion engine work at that attitude, it is designed to work at double that?

    Yes.

    Thanks.

    So we need to build a sandpaper type micro rectenna skin for the airships that can turn microwaves into electricity and get the airships to circle the earth a few times to get into orbit.

    How do you keep the beam aimed at the airship without frying the avionics of random aircraft?

    Using a maser and telling aircraft where it is, they shouldn't be flying if they are that dumb.

    Skeptical Ha!!!!!!!!

    You don't need the maser, just a big steerable antenna. I have personally seen an aircraft in flight powered by a microwave beam. It's not something you forget, unless you are considering it as a serious proposition.

    I suspect that wayward birds aren't likely to forget it either.

    Okay, as the idea behind airships to orbit is that they start from a floating station above winds and clouds (and birds) they should receive longer lasting sunlight, IF solar cells can be made lightweight enough then maybe sunshine would do.

    I prefer microwaves.

    And of course orbital rings, momex tethers, and startrams.
