I wonder if this technology has been sitting waiting to be discovered for a long time. I read somewhere that the astronauts who walked on the moon has gold-covered helmet glass to shield them from the sun.
- brnt 4y agoAh, those famous moon fogs...
- herendin2 4y agoThe gold layer may have been on the inside
- satvikpendem 4y agoMoon dust is very deadly, breathing it in is akin to getting pneumonoultramicroscopicsilicovolcanoconiosis.
- dylan604 4y agoah, those famous sunrises with no UV protection whatsoever. fog would be a blessing
- nkrisc 4y agoWhen the sun rises on the moon, it’s just the sun versus you and whatever protection you can wear. There’s no atmosphere to coddle you.
- bombolo 4y agoIt's probably just very expensive and doesn't survive cleaning them.
- Ekaros 4y agoGold is extremely ductile. As thus thin layers of it are pretty cheap. Not surviving is probably more reasonable reason.
- weberer 4y agoGold leaf is actually very cheap since its so thin. I can't imagine something like this costing more than a dollar in gold.
- lebubule 4y agoThe coating is just a few nanometers thin. Price wouldn't be the main issue there.
- blackbear_ 4y agoI can imagine the material used for lenses is also rather cheap, and yet somehow they end up costing undreds of euros each... I wonder why...
- lebubule 4y agoWork and studies of metal films and thin films as well as their fabrication has been going on for more than a century. Basically since electromagnetism is popular. Fabrication tools for thin films have improved a lot over the past decades though. We can now fabricate exotic structured matter at the nanoscale that doesn't respond as the bulk counterpart.
