It reminds me of a rail gun. Gunpowder packs a lot more energy per
volume or mass than capacitors. A lot.

As gasoline packs a lot more energy than batteries.

I wonder why that animal injector thing doesn't just use a spring. I
have a blood sample lancet thing that has a spring; it works fine.
It's cheap and no batteries are required.
