What powers the pump?
- hollerith 2y agoI don't recall. They've got huge fire engines (and permission to keep the engine running as long as they are fighting a fire) so the solutions now on the market might run the pump off of electricity generated by the engine. For disaster preparedness, my initial guess is that alkaline batteries (e.g., D cells) would be a good solution because unlike lithium-ion batteries, alkalines remain healthy and keep their charge through years of storage.
