While you want your free entertainment in the form of TV shows perhaps some people want it in the form of internet or gadgets to play on.

Also I think the concern given to emergency broadcasts is rather unrealistic. Could tcp/ip not deliver even more reliable emergency broadcasts than TV.

In some of the very sparsly populated and rural communities will there be people with these devices close enough to the TV sets to disrupt it?

Cooler Silicon Lasers Via Energy Harvesting 31

Light Licker writes "UCLA researchers have developed a way to cut power use and heat output from a silicon laser used for optoelectronics. Both have been problems because silicon absorbs too much light — producing high-energy free electrons that make heat. One of Intel's best silicon lasers produced 125 times more heat than usable light. The UCLA team added a diode to their laser which can harvest free electrons and use them to help power the circuit — simultaneously cutting heat output and power use."
