Cheaper LED lights?

[a_steep_hill]

This sounds promising: these guys figured out how to make a practical LED on silicon, rather than on sapphire. Much cheaper that way. Also, this should let us produce much larger LED, since making and handling big silicon wafers is something that industry knows how to do.

Very good news indeed.... and maybe they should look into not overcoming cracking of the gallium nitride layer, but instead work on it cracking in an order manner [like basaltic larva i.e Giants causeway in Ireland]..

Doing so would form discrete domains which would be the basis for individual LED's. But instead of being dots, they'd be tessellated hexagons.
