Hydraulic ram pumps are mechanical devices that employ the water hammer effect to pump water without using any engine, neither electric or combustion.
The University of Warwick in the UK developed a series of ram pump models that can be built with materials commonly used in any workshop. They are basically pieces used in irrigation systems. Here in Rovies, they were building one to gradually introduce more sustainable systems in the olive production. I joined the team that was doing the work, and here is the result.
Ram pumps can be built in multiple ways. There are industrial, made with materials and advanced technology, but can also be built with simple, reused materials and do not require the use of a workshop or specialized tools. To pump a minimum amount of water, we can use standard parts pvc those used in water supply installations. In Paliomylos we did the experiment to see if it would be possible to irrigate the future edible forest with a small hydraulic ram pump that brings water from the canal to a reservoir at the upper end of the plot about 10 vertical meters of the channel.
An immediate objective to overwinter in humanly tolerable thermal conditions was to improve the heating system of the house. The place used for the waterfall coming from the channel to the old mill wheel, was converted into a big fireplace. The only problem is that however much you make fire, heat escapes through the flue, and only the first meter around the fireplace get some heat. On the other hand, air currents due to incorrect adjustment of doors and windows, fed the huge chimney draft, and bring cold air into the house. The solution: better insulation, confine the fire to retain heat and control the draft and create a convective hot air system to fill up the room. As a bonus, the system will allow cooking and heating water for domestic use in the future.
It is time to build a biomass gasification cookstove. With this tutorial you can do it in an easy and cheap way. You can adapt the instructions to the materials you have, or you can find or acquire. There is no overly critical parameter. If you make modifications and does not work 100%, adjust and modify to achieve better results experimentally.
The tutorial teaches us how to build a biomass gasifier cookstove called Kaña!!!, Version 1.0, and includes:
An explanatory text which lists the material necessary to perform it.
The needed tools list.
A video recorded during the biomass gasification course I did in Sunseed which shows all the steps to follow.
The instructions for use.
A video about the success story of Lucia, who built the Lucificador and got the absolute record of burning time with a powerful flame for 35 minutes using 350 gr. of dry cane.
The biomass cookstove base structure has been reinforced and has been transported to the main house where it will be used. We started to cook usually, demonstrating that whatever can use it, has a very simple operation and is very efficient. We’re burning cane and almond shells. In short will be prepared other fuels. 2 hours of heat, are easily obtained. The gasification is very good, and does not generate smoke, so can be used perfectly to the side of the house.
We also have built a structure to support the solar oven with turning wheels that allow to point towards the sun. The box has been coated with fiberglass to protect it from the elements and painted white, to reject the sun’s heat on the outside. At noon you reach 144 degrees celsius, allowing to cook many dishes perfectly.
