Kind of dismissed this cement battery thing when it first came out, but maybe it has legs?

Concrete “battery” developed at MIT now packs 10 times the power
New concrete and carbon black supercapacitors with optimized electrolytes have 10 times the energy storage of previous designs and can be incorporated into a wide range of architectural forms.

For perspective, phone and laptop batteries have ~300-500 cycles before they drop to 80%. EV cars ~1500-2000. These 10,000 cycles before dropping even 1% (to 99%). Battery tech keeps getting better (if we invest in science).

In 2012 almost 40% of UK electricity was coal.
Since 1 October 2024 it is zero.
This is the moment Britains last coal power plant shut down on 30 September - the end of 142 years of coal.
