Intro: The Pent Up Power of Kitchen Waste! (part of the Bio-fueled Water Pump Project)
The video shows the potential power of yeast or lactic acid fermentation of kitchen waste.
It is part of the bio-fueled water pump project. I have already made a proof of concept water pump that harnesses this power to recirculate water or compost tea to plants to help them grow better.
The other video used a much smaller "power pack" to pump water. Just yeast and sugar.
Hopefully this one shows that there is serious power in kitchen waste (moldy bread, stale pie, potato skins) and garden waste. (Slug damaged green beans, and ground up morning glory stems).
So there is no need to buy yeast or sugar to power your pump. Even the grass from the lawn mower can be used to water your indoor plants!
Please start your own version now and show people that this can be done. If it is just me, nobody will ever believe that this works.
