"..."lunar bulldozers", which will warm the soil and then will shovel up the isotope from the surface..."

Im not familiar with the properties of Helium-3 but this doesnt sound right. Is he actually saying that clumps will form on the warmed beds or is that just the 25 cent explanation for non-scientists?

What they are saying is that the Solar Wind imbeds the He3 in the lunar soil. Helium (of any kind) is a noble gas it does not chemically bind with any other element. So the bulldozer warming the Lunar soil will drive it out of the soil and there would be a system to vacuum the Helium up and capture it in tanks.
