Human Power Waterpumps

 When you first get out to build your Earthship, you might want to live on the land to save rent/mortgage and devote more time to building. To do so, unless you're part of the 1% (not the 99% like the rest of us) You might have to use more inexpensive ways to do things. Electricity might not be the best if you can't afford to connect to the grid and haven't saved enough cash to connect to the grid or buy a lot of solar power.

Water pumps can be a drain on electricity that you might have better uses for - like power tools or computer and internet (if you're like me and need to work online for a living while you're building). Anything you can do to save electricity can help til you get a good solar pump.

Treadle Pumps:

Using your own weight to pump water is probably the easiest way. You just step onto the treadle and your weight pumps the water up. You'll likely use your arms more than your legs to build your home, so you should have a little energy left in your legs to pump yourself up a nice shower.




Here's an AutoCAD simulation to show how it works



Bicycle Pumps:

This looks like they took s treadle pump and attached it to a bicycle.
I wonder if it is easier than using your own gravity to move them.
