Alternative Power Systems

So, I'm familiar with Steam, Electric, and hand powered machines... What else can you do to power a machine (say, for example, a car or a pump)?

Requirements:

• Assuming you build everything from scratch, so compatibility isn't an issue.
• Efficiency isn't an issue as long as it can at least work.
• Safety isn't an issue as long as the risk is reasonable (Safe enough if careful).
• It should reasonably obtainable/craft-able (I should be able to go to Lows/Home Depot and build it myself.)
• Manpower/skill to build it isn't an issue.
