The silicon wire arrays created by Atwater and his colleagues are able to convert between 90 and 100 percent of the photons they absorb into electrons—in technical terms, the wires have a near-perfect internal quantum efficiency. "High absorption plus good conversion makes for a high-quality solar cell," says Atwater. "It's an important advance."
Almost too good to be true, but if it is (and it scales well), invest in some desert land area, because solar has just become viable.
At 20 mg lithium per kg of Earth's crust, lithium is the 25th most abundant element. Nickel and lead have the about the same abundance
Not apparently a crisis, although it might be more expensive to mine due to the use of electrolysis.
Instead, the L-3 CyTerra device sends pulses on 200 different frequencies, one at a time, ranging in sequence from 3101 to 3499 MHz at 2 MHz intervals.

The system is sensitive enough to detect the chest motions of a person who is unconscious but breathing, or the slight swaying of a person trying to stand perfectly still
If you have a procedure with 10 parameters, you probably missed some.
