Sunlight + gold = steaming water (no boiling needed)
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

Scientists Say: Yottawatt
On Earth, scientists measure energy use in watts. When you have lot of those watts — one million billion billion — you have a yottawatt.

Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.

Black hole smashup sent out ‘yottawatts’ of power
When two black holes collided, they released a lot of energy in gravity waves. How much? How about 36 septillion yottawatts of power!
