It's a new riff on an accepted idea. I like that they're always trying something new, but I'm doubtful it will lower prices any time soon. I can't imagine making silicate covered paraffin balls/pellets is cheap (as a process). If the design takes off it will undoubtedly get streamlined, so that's always good.

On the upside, sand is CRAZY available. Deserts, beaches, take your pick. I'm not sure it will work for a rocket heater as it gets way too hot and the spheres likely wont be able to handle it. My money is on using them for grow-beds. Can anyone else see laying down a layer of these as a "pseudo greenhouse" for your plants? Keep them nice and warm for longer periods? Plus, none of the ingredients should cause problem if they were to burst.

Anyone else have other thoughts for them? Embed them in drywall? Coating between glass layers?
