As long as De Beers doesn't assassinate him, Linares will provide an amazing jump in technology. I've been on this for a while, but I haven't heard much from others about this. This is really amazing and potentially HUGE. Is De Beers keeping it quiet?
Manufactured diamonds

I mean diamond is amazing... It's the hardest material, it won't expand in heat, won't wear, is chemically inert, has incredibly high thermal conductivity and is optically transparent. Oh, AND it can be made semi-conductive, making it the PERFECT material for constructing integrated circuits. This would be a leap forward in chip design allowing tiny chips with no thermal dissipation issues. Seriously tiny and powerful beyond anything currently out there.
