You can almost feel the sheer horsepower in the roar of this machine. Well, not really. This kind of mechanism was more than common in the past, but nowadays you can only find small engines that can't even run a vehicle. They can, however, do a decent job powering small machinery, like a Chainsaw (incomplete) or doing other small jobs - do not underestimate the opportunity cost!
This is required in the construction of:
- The engine requires no fuel, although some of its applications, like a Chainsaw (incomplete) and the Reactor, require batteries to work, implying it's electric. Mechanisms using electricity to produce mechanic power are usually called electric motors rather than engines.
