This is horrible news. There are plans to build and launch a 250 mile wide solar panel around the moon.

Chinese satellite-killer missile should take care of that.

I can only hope that no one in ther right mind is taking this serious.
Why don't they just pave the whole moon and build condo's on it while they're at it?

It's to power the cheese mining operations they plan to start. Probably use the little green men for cheap labor before laws get established that you can't use little green men for labor in labor intensive cheese mining moon camps.

So they generate the 13K TW of power (over 3x the output of all US power plant generation in 2011) using the 250 mile wide belt of solar panels around the moon, and plan to transmit that power in useful form to earth via laser or microwave transmission. The last ~100 miles, and the last 10-20 miles especially, this laser or microwave transmission will increasingly have to pass through the atmosphere without undue dispersion or interference.

QUERY: if microwave or laser transmission of power is effective enough to transmit such huge quantites of power at the necessary rates through 10 miles of thick atmosphere...why do existing earth-bound power plants need wire transmission lies at all? Why aren't we already using lasers and microwaves to transmit power, perhaps with relay stations every 20 miles or so? Transmitting enough power via antannae to send a coherent signal over distance is quite another thing from transmitting enough power to cook 20 million turkeys on Thanksgiving.

Mayidunk's post was tongue-in-cheek. ;) Pink Floyd reference to "Dark Side of the Moon" album.

A 250 mile wide solar panel around the moon? In addition to other issues, this will have to reflect sunlight back to earth, adding to light pollution.

IMHO the proposal is merely a piece of conceptual performance art and corporate promotion stunt, rather than any actual seriously intended undertaking. Christo in corporate garb (Christo is the artiste known for draping large-scale swatches of colorful cloth over various landscapes).

At that point I'd be worried about getting fried by a "death star" than LP. :)

I think this firm is very serious about developing industry on luna. After all, by 2035 (their projected start date) we will have accomplished our goal of destroying the natural environment on this planet, the only inhabital one in our solar system. So it only makes sense to begin colonizing and destroying the next closest rock. Check out Shimizu's website, they have posted pictures of their dream.

As compensation maybe they can project a virtual image of pre-industrial luna for us to look at.

Are there certain treaties that have to be circumvented? But, I doubt the amateur astronomy community has enough captital to out bid (bribe) the necessary officials to convince them not to wave any restrictions.

Money should then be spent on lobbying for Shimizu to project the virtual moon. That way we will have two moons to look at. No worries. Virtual polar bears, virtual birds etc, etc. My only concern is how seeing and transparency would effect our views of the virtual moon.

I don't see why we don't mount a large solar cell on the edge of a small event horizon and place it in orbit? We could then run power cables through the other side (i.e. worm hole) and attach them to the power grid (e.g other side of the worm hole). Seems rather simple to me. But then what do I know, I'm no astrophysicist, but the Dr. would know how to do it.

Cheers,
Randy ;)

Tesla wanted to do microwave power transmission. He lost the war due to a number of factors (Edison and many other influential people killed his projects financially and with propaganda)....

I have a much more modest idea. All you need is to attach one end of a cable to Earth and the other to the Moon. Then you can use the Moon's orbital energy to power a generator more or less forever.

The Daily Mail ran the Shimizu lunar ring story in 2011. I wonder why it's popped up again. This might be a great premise for a science fiction anime series, but it distracts from thoughtful action to address Japan's current power generation problems.

Maybe the distraction is intentional--an effort to direct attention away from the setbacks that have plagued efforts to deal with the Fukushima nuclear plant disaster. Because of its experience with nuclear plants, Shimizu Corp. participated in the construction of bolted-together tanks that were intended to hold radiated water temporarily. However, last August it was reported that one of the tanks has started to leak.

Whether the leaking tank was among those built by Shimizu is unknown. But the point is that if timely fabrication of reliable water storage tanks is such a challenge, perhaps the focus should be on power generation/conservation solutions that are both green and currently available.

Starry-eyed energy proposals are fine only if they don't deprive us of being (literally) starry-eyed.

This is simply a bad idea drawn from the "hard" SF genre and given some credibility. It's really laughable.
