Why solid-state batteries keep short-circuiting

Batteries that use solid metal as their charge-carrying electrolyte could potentially be a safer and far more energy-dense alternative to lithium-ion batteries. Unfortunately, these solid-state batteries have been plagued ...

Harvesting heat and electricity from the sun, when you need it

Solar energy is abundant and frustratingly ill-timed. A sunbeam can become either electricity (useful for running modern life) or heat (useful for keeping spaces warm). But conventional solar hardware is single-minded: Photovoltaic ...
