The word "battery" is often misused anyway. A "battery" is a collection of things, from the military use as a coordinated artillery group. A single "battery" is really a cell.
The word has been used that way for a long time, so I'm not gonna stamp on my dictionary and insist we look at the etymology. But it does show how the word's usage has shifted, and a continued shift to call this thing a "heat battery" seems comprehensible.
- magicalhippo 1y agoGoid point. I do like "heat battery". My complaint was more that just "battery" implies storing electricity directly in common parlance these days, and the fact that the heat output is used directly is quite significant. Had the headline called it a heat battery I would have had no complaints.
- s1mplicissimus 1y agoHeat battery sounds pretty accurate imo. There aren't really any batteries "storing electricity directly" though. Every battery type I'm aware of stores either potential (storage lake), mechanical (swing wheels), thermal (this type) or chemical (LitIo batteries) energy, which can then be transformed into electrical energy. Electricity itself seems to be very unwilling to be stored directly.
