Last workweek ablog poston Blue Origin ’s site made a title that , if verified , could dramatically increase the prospects for establishing on-going stand on the Moon . However , the rum lack of promotion the party – not usually known foravoiding promotion – has so far give the declaration propose they may still have some doubts about the applied science .
The claim is that Blue Origin ’s engineers have worked out how to make work solar cell and electricity transmission line out of the dust and rubble found on the lunar aerofoil , known asregolith . If you want to see humanness establish a permanent presence beyond low-toned Earth orbit , or even just put some fancy telescope on thefar side of the Moon , this strike into the “ Brobdingnagian if true ” class .
Lunar alkali will involve a caboodle of power , including for heating plant and cooling given the tremendous range of temperature the Moon experiences in the course of study of one of its month - foresighted “ daytime ” . With no fossil fuels to mine or idle words to tap , that can add up from only two source : solar or nuclear .
To extract the elements required for making solar cells, Blue Origin first proposes to heat the lunar regolith until it melts. Image credit: Blue Origin
Although NASA ’s programme currentlyrevolve aroundnuclear power stations , some recent modeling suggests aseries of solar farmslocated near the lunar poles would be sleazy . cable television service could plug in the farm so that at all times at least one was providing sufficient power .
Nevertheless , the idea is still expensive , and most of the price would lie in transporting the solar panels and transmission lines , rather than their manufacture or instalment . If they could be made on site from locally - sourced stuff the cost should plump .
That ’s what Blue Origin is claiming they can do . Naturally no one has tested the idea on placement , or even made the panel out of the rock music brought back by theApollomissions . The sample distribution are too precious to be used in bulk like that .

Instead , Blue Origin made “ regolith simulants ” that play off the physical composition and grain sizing of sample gather by Apollo astronaut , and work with those . “ We have pioneered the technology and demonstrated all the steps . Our approach , Blue Alchemist , can scale indefinitely , eliminating baron as a constraint anywhere on the Moon , ” the blogsays .
The process starts by ignite regolith to 1,800 ° C ( 3,300 ° farad ) to make it melt and then electrolyzing it produce iron , silicon and aluminium . The oxygen released in the process would certainly amount in handy on the lunar control surface as well . The 99.99 percent consummate silicon meets even the exacting standards of the photovoltaic industry , fend off the expensive chemical substance unremarkably used on Earth .
Silicon accounts for most of the weight unit require for solar panels , so once it is available on the lunar surface the cost of bringing the other component would be manageable . Nevertheless , Blue Origin claim they can produce everything required to make solar panels on website , cutting out even those small-scale additions . This include the layer of chicken feed to protect the cell from damage . The same goes for the wires that could transmit the electrical energy back to base .
The process is energy intensive , so a large initial solidifying of solar panels would need to be bring from Earth to prime the ticker , but once it got started it would be ego - sustaining .
" Because our applied science manufacture solar cell with zero carbon paper emissions , no urine , and no toxic ingredient or other chemical substance , it has exciting potential difference to directly gain the dry land , ” the web log summate .
The idea ofusing lunar dustto benefit Earth in a very dissimilar way was raised just last week . In the latest fount it is not the dust itself , but the lessons we have acquire from it , that could help relieve Earth from clime change .
If the body of work has been published in a journal or otherwise peer - reviewed , Blue Origin have not remark it , however . They have so far failed to promote the operation , not even mentioning it on their social media channels ( although someteam members have ) , so we may necessitate to wait and see if a spell is still missing .
