Lab fuel cells reach 0.726 W cm−2 at 400°C
The team tested four compositions, with 4% magnesium delivering the best conductivity.
Solar, wind, nuclear, grids, storage: the electricity that will run everything else.
Energy is the mother section: everything else this journal covers — computing, vehicles, factories — eventually plugs in somewhere. We follow solar and wind as they keep cutting prices, nuclear reinventing itself as small modular reactors, geothermal, hydrogen where it actually makes sense, and above all the grids: interconnections, bulk storage, demand management — the plumbing without which no megawatt is worth anything.
The through-line is the kilowatt-hour: its cost, its footprint, its availability. An efficiency record only counts dated and sourced; a power plant only counts once connected. The section favours verifiable numbers — auctions, commissionings, production curves — and the players Western general media rarely cover, from Chinese electrolyser makers to island grids going 100% renewable.

Air bubbles were injected into circulating water behind a 20 W solar module.
BEST is being built in Hefei to demonstrate fusion-generated electricity by 2030.
