Switchable material could harness the power of the sun —
even when it’s not shining.
It’s an obvious truism, but one that may soon be outdated:
The problem with solar power is that sometimes the sun doesn’t shine.
Now a team at MIT and Harvard University has come up with an
ingenious workaround — a material that can absorb the sun’s heat and store that
energy in chemical form, ready to be released again on demand.
