  • Do you sell plans with dimensions to make the setup where you had the one cup on the floor and the other cup way up on the table?

  • no plans for the moment ...but come soon!

    please wait ! thanks !

  • i think this is a similar idea to the percolator in your coffee maker

  • no it's thermodynamic cycle like stirling motor

  • As the water in the right hand side oscillates, it produces pressure changes in the pump section on the left. No percolation of the pumped fluid is going on. The pump section is two check valves that allow it to suck in water on a low pressure spike, then push water out the top on a high pressure spike. This little pump is drawing water from what looks to me to be about 1 meter below the outlet. If the sun could produce the heat of that blowtorch, it could water some plants outside. Nice!

  • cool!! congratulation you've understand

    very well!

  • nice but that looks extremely inefficient. I would think there are many better ways to do solar work. sterling engine or photovoltaics for instance

  • doubt it.

  • Kinda like a coffee maker?

  • Thermal syphoning?

  • Guessing the black cylinders contain check valves, arranged to allow upwards flow. Expect they'd have to have fairly low lifing pressures.

  • Question is there any check valves in that? and if so where are some plans for it?

  • my Mr coffee does this a lot easier....AND I get to drink the coffee! now thinking of a solar coffee maker !!! but when its that hot do you REALLY want to drink coffee? maybe the coffee grounds can be the fuel source? boiled hot water in the garden to cook the plants. lovely. but then no coffee.What a waste of time!

  • yes but if you put it in your garden, with a parabolic mirror instead of the 'lighter' it's 100% free pumping :)
