A METHOD OF MINING ASTEROIDS CHEAP


Asteroid Mining Problems (R. Brak Author).


MOVING ASTEROIDS AT LOW COST

As you see on the second memo post, Moving Asteroids While We Save may be easy, though it would take years or months to move the asteroids near us. The method is to use cheap beams (either on a ship close up like with a maser or farther away which would be of worth even if slower) to move a small asteroid, to move a larger stone, and so on till a larger stone is moved near us.

On the second link above about Asteroid Mining, the author of the site says it would be cheaper and easier than moving asteroids and then going up and mining them, to just mine minerals and other worthwhile stuff from the earth. When it first was evident that asteroids might be a source of future wealth for explorers and colonization those who believed in the worth of asteroids like me were basing this on the probability of many types of composition of these small worlds, just as the moons of Jupiter and the other planets are so unlike in the geology, minerology, ect. This was implied in the conclusion of most that asteroids were of worth to mine (and for other important uses like power generation by spinning tethers, and launching satellites from the tethers). The percieved value of asteroids wasn't just that they were merely of worth for returning the minerals and chemicals to Earth. In truth most of the use for now would be in mining them near the Moon or Mars, with no water on the moon, a comet in Low Earth Orbit, LEO would be a rich (and cheap) source of oxygen for breathing and for rocket fuel, and of water and hydrogen to wash down the lunch (real thirst if no Diet Dew on the moon!). Otherwise it would cost hugely more to boost that much water to LEO and beyond, this is why mining asteroids is considered rich, not because of either mining asteroids in competition with earth mining or for other minerals like platinum just yet, if your wife is so kind she would help all the world, this may be why you have the world's only talking chipmunk, most on the FM just sing.

On the site about how much worth mining asteroids would be the author avows that if it took a lot of energy like with masers to move asteroids, the power company would be able to sell the power cheaper to people here so they wouldn't be able to sell the energy to the House of Stone and Light Moving Co or use the asteroids for mining minerals like U 237. This is improbable because if the people here bought the power cheaper, the power companies would win more if they paid the business that were hoping to mine the asteroids for profit. And even if they sold it at what Brak says is the much higher price to move the asteroids or comets, the people moving the comets would presumably be a seperate business so they would pay more initially to recieve a much higher payoff later on when the asteroid was in reach on LEO, Business is worth if the overall worth is much higher than the price paid. Of course, to mine the Earth would be cheaper if we have to move the asteroid with expensive machines without the cheaper maser laser method as on the link, and then go up to the asteroid and mine it with conventional clumsy 0g mining machines with mere 21st century technology. Eventually even if so more advanced mining machines may be built. Brak says on the page About Problems With Mining any mining science developed for use in mining in orbit would also make mining on Earth that much cheaper, and so no asteroids would be mined. This may depend on the wealth of the metals and minerals like Uranium the asteroids hold other than water. If there is more value overall, or a lot more value for any reason (especially if materials) there will be business involved with the mining and it would be feasable. Based on the worth of mining the asteroids, where the cost would seem to be higher by Brak's belief in the lack of mining science, and by using cheaper methods than Brak may be aware of to move the asteroids or comets to LEO, the cost would be improved via my invention of the following plan;

It would be a much cheaper way to first move a larger medium size asteroid to LEO by the beam and gravity method method and then other small stones would be moved nearby also in geostationary orbit. Nets or loops would be wrapped around both the big and small stones, and using the outward centrufugal force of the heavy stone to lift against the gravity, the small mineral rich stone would be lowered gently to the earth's surface, where it would then be mined. To add more lift at the lower part of the descent where the gravity would be stronger than in LEO, the outer stone or comet would be lifted more so the supporting outward force would always be stronger than the gravity. If the tether cost too much to make strong, a lighter tether and lighter small asteroids with the best materials would be lowered, and with air pressure and the larger stone spinning so more centrifugal force would hold in orbit at lower radii from the surface without descent, allowing a shorter and lighter tether.

I've lived with listening devices for years! A woman who lives near us up the street owns a dog who watches a lot by hearing!

I've read where they are monitoring to see if there are any asteroids to reach us has concluded that there are 40 house sized rocks between the earth and moon a day we miss, or the other where we read about a scientist who says he has a photo that seemed to prove that the Earth was putting on 200,000 tons by house sized comets hitting the Earth a day. The photo looked to me like it was chalked, where "the comet' was above the Earth. And if the asteroids were hitting the Earth and Moon at this rate, the Moon would be resurfaced in hundreds of years not billions. Even so once in a while a small stone the size of a soccer field whizzes by in accord with the expected frequency of Tunguska and other comets like the dinosaur comet and the resurfacing rate of the Moon and Mars. If these are of worth they might be zapped ahead of time with a maser or laser to easily move them into Earth orbit. Cheaper than using tethers and a big stone would be to gradually lower a small rock while slowing the fall with the beams from the surface. Even if they fall nearer the Earth, most of the descent would be slower if the beams were used with air resistance, if the asteroids to be used were small, and the cash was above. (I never throw out my VISA, my hot socks or my Stop Signs, I don't want the garbage truck knowing more than I do!) The wealth of orbital mining would depend on whether the asteroids are actually rich in materials, but some of them may be of worth for mining after lowering them safely to Earth at any rate because of so many types of moons and planets, so there may be many rich asteroids to mine if we choose the best, with Earth's minerals being more rare in 2057 AD. With fusion power possible or other machines like Gravity Power Machines we may be able to recycle a lot more in those days, even so the population will increase indefinitely so materials will be more of worth and asteroid mining by methods like this will be more under consideration as time goes on. While the most cheap would be to detour asteroids near us, if not feasable because of money saved for the weather woman on TV 27 it might be feasable to send out robot ships with sensors and beams to find and move the richer asteroids to reach us and then to the surface, this might be most economic if large numbers of small asteroids were moved toward us at once.

A few of the first asteroids may even be used to see if our methods of stopping the more unsafe ones like the dinosaur comet are sound, sort of like how fire drills for fighters use real fire they learn how to control the fire well by safe practice. Some larger asteroids could be moved near to the earth cheap by the beam and not actually to the Earth, and this would be used to see if our methods of deflecting them are reliable. If we move the asteroid toward the Earth from a great distance, then we could see if we can move it away reliably, and so on, by cheap laser or maser methods or other ships like the sensor robot. This use of tethers and moving the stones by way of masers or lasers and gravity may be repeated often, it's good to live in Miami Beach, you're always treated with optimism if there is gossip about weather!
