Biodegradable torpedoes for dark water

[NicholasRadzykewycz]

I am wondering if anyone has tried to make a fully biodegradable torpedo for use in dark, murky water where recovery of a spent torpedo is almost impossible. They have a variety of biodegradable filaments out there:

Why launch it in a dark murky water?

A solution to a preventable problem...

I'll presume you're talking about electric torpedoes.
So the torpedo body will break down after a certain amount of time. What happens to the grease in electric motor, the electrolytes, heavy metals in the electronics and batteries once they're exposed to the water?

No was talking more about like rubber band torpedoes not electric drive

I played with rubber band torps. Didn't play out (in the slightest). Not enough energy stored in the bands to make a good run (at least 20 to 30ft). More like 3ft. In tiny torps, gas is easiest, though very fickle to get working right. For 48th and 32nd torps, you're in the neighborhood of electric.

For the torps to run properly, you want slight positive buoyancy, so loss of the weapons isn't really an issue, unless you just want to leave them littering the surface of the pond. Invest in a cheap surface tug or something and just drive around collecting your spent weapons, ready for another salvo after recharge.
