Engineers use simulated moon dust to make glass
Engineers have successfully manufactured glass using simulated moon dust, and found this “moonglass” works better than Earth glass in solar panels.
To test the idea, the researchers melted a substance designed to simulate Moon dust into moonglass and used it to build a new kind of solar cell. They crafted the cells by pairing moonglass with perovskite—a class of crystals that are cheaper, easier to make, and very efficient in turning sunlight into electricity. For every gram of material sent to space, the new panels produced up to 100 times more energy than traditional solar panels.
…When the team zapped the solar cells with space-grade radiation, the moonglass versions outperformed the Earth-made ones. Standard glass slowly browns in space, blocking sunlight and reducing efficiency. But moonglass has a natural brown tint from impurities in the Moon dust, which stabilizes the glass, prevents it from further darkening, and makes the cells more resistant to radiation.
Though encouraging, they are many unknowns that could become show stoppers. For one, this research was all done in Earth gravity. In the Moon’s 1/6th gravity the results might be very different. For another, all they have done is demonstrate a way to make glass using Moon dust. That is a far cry from building solar panels, as implied by the press release.
Nonetheless, the results demonstrate one more way in which a lunar base can eventually become self-sufficient, the inevitable goal.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

I’d suggest looking up “crystal polymorphism.”
