The article says:
Luckily, lunar dust is also susceptible to magnets. Tiny specks of metallic iron (Fe0) are embedded in each dust particle's glassy shell. Taylor has designed a magnetic filter to pull dust from the air, as well as a "dust sucker" that uses magnets in place of a vacuum. He has also discovered that microwaves melt lunar soil in less time than it takes to boil a cup of tea. He envisions a vehicle that could microwave lunar surfaces into roads and landing pads as it drives, and a device to melt soil over lunar modules to provide insulation against space radiation. The heating process can also produce oxygen for breathing.
In other words, the article is not reporting on a peer-reviewed article, but instead just mentioning a claim by somebody, without evidence, except for the sketch below.
Is this really true? Can you really melt lunar regolith with microwaves in a remotely practical way?
Or are they really just talking about some permutation of a conventional RF inductive heating of a coil, which is wrapped around a conventional crucible?
Professor Taylor is a well recognized geochemist and worked with the Apollo astronauts and scientists.
On the other hand, as a calibration point, the article also says:
NASA will use these findings to plan a safer manned mission to the Moon in 2018.
Lunar dust melts readily when exposed to microwave energy. Professor Larry Taylor of the University of Tennessee envisions a lunar paver fitted with microwave generators that could sinter, or melt, lunar soils into landing strips or roads. Credit: Larry Taylor
