I am a programmer. And a engineer. Me and my team have been working on a project. Can't really put much detail in the project other than it needs to be powered by something heavy. This project consists of land and air activity so it is a electricity killer. We have tried a very heave battery and charger_ failed. Gasoline isn't an option in this case. We have tested many forms of electricity- but non seem reliant. It's been about 3 months since we have tried. Any ideas? Or should we just give up.
compressed air or co2 cylinders,fire extinguishers?
Get a diesel powered generator.
