Bio Fueled Water Pump

I'm very unimpressed with your yeast powered siphon system. Showing a video with excuses for why it does not work this time but making a claim that "once upon a time" it did work does not inspire confidence. The one meter of maximum vertical lift but with a net final drop in elevation tells me that you do not know the basic kinematics of how a simple siphon works. Beyond that, I recommend that you only post videos of a system that works. Nobody is interested in an excuse.

What on earth are you talking about? It worked fine.

A net final drop in elevation? And it isn't a "yeast powered siphon system".

The siphon is just a switch that is inside one of the bottles. You didn't understand it.

Guess that is my fault. Certainly could not be yours.

Ok, I'll give you the benefit of a doubt since the link you provided sent me to a site that only gave me a commercial, just like Lynlynch. One of the displayed related videos under your name is what I did view and was disappointed with. (I did have to sit through a second commercial, somebody has to pay for the bandwidth.) In that video there was a failure of a hose. So you may be accidentally presenting the wrong video.

All I got was a stinking commercial.

Sorry, but I don't understand what makes people think you can subject someone to a compulsory commercial every time they want to look at the video.

Good luck with the enterprise.

Sorry, I didn't know that they put commercials in front of the videos. I have never seen a commercial played before one of their videos so it must be a recent change.

Its on youtube too.

I'm still not sure what you are doing but maybe you've rediscovered a version of Heron's Fountain or another of Hero's siphons that gets some added power from fermentation gas.

The plant material require water to produce.

Cabbage would require about 250 mm (or more) of irrigation per season to grow,

if a plant occupy 20 x 20 cm the requirement would be 10 litre irrigation per plant.

If the energy of irrigation, harvesting etc is ignored you would at least require the "pump" to deliver 10 litre at some head to break even.

Back to the drawing board.

The person should rather eat the sauerkraut and use the energy to operate a hand pump to pump the water. At least more effective use of the bio-fuel.

You can still eat the sauerkraut or drink the beer. It is not wasted.

If you use the saurkraut fermentation with weed leaves, you cannot eat the saurkraut but you get speedy compost tea instead, (I think).

The CO2 is just a waste product that nobody uses. I am thinking more of a small scale thing to recirculate water round a propagator, or plants in a greenhouse or something like that, where hand watering is an often forgotten chore. In the small scale ventures where people go away for a weekend, they often come back to dessicated seedlings.

Or for the windowfarms project. So even when the CO2 gets out of the pump, it is feeding the plants.

http://nxtwave.tripod.com/suctionpump/index.html is some animated details of my first working water pump. From over 20 years ago.

(It worked on vacuum but for this pressure operated pump, you should be able to stack pumping stages in the same fashion).
