Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

You can, but it is totally inefficient
You get about 30% of the energy out that you put in
So it's more like a really bad battery
But with all the disadvantages of having to handle gas!
Yup! It has really good gravimetric energy density, but really bad charging efficiency.
Not THAT bad, really, it potentially has a much better mileage-to-weight ratio and sidesteps the issue of lithium recycling and politics
Great to gravametric energy density, okay volumetric energy density, great availability, terrible charging efficiency, and complicated handling and storing mechanisms. Lots of tradeoffs.
