    Talk about pie-in-the-sky! :rolleyes:

    Anyway, will there be anyone left in Japan under seventy by 2030? :)

    Fascinating but extremely dangerous in case of loss of control or terrorist attack.

    Not only is it ludicrously far-fetched, it's ludicrously unnecessary. What we need to be doing is using less energy, not harvesting/generating more. Plus. That'd look stupid on the moon.

    Would love to have a science backround to work on the r&d for that. Surely even the reserch into transmitting power would lead to some advance in the technologies involed.

    Actually we need more energy. And we'll need even more, the more powerful our PCs and devices will get, and the more we'll be on this Earth.
    But we need less pollution.
    So we need pollution-free energy.

    But we definitely do not need a death ray! :D

    Back in 1964 they were able to power a small helicopter remotely with microwaves, by 1975 they had efficiencies of 45% over a distance of a mile - this beats most wireless chargers today.

    The moon proposal needs lots of long distance power transmission here and on the moon

    IMHO it would be easier to use mirrors in orbit , lighter and cheaper than panels. - use dichroic or fluorescent ones to pick the most efficient colours to match the cells and filter out excess heat / UV as appropiate
