Innovative water pumps enabling better healthcare.

Thermofluidics' NIFTE/DAHR (appendices 1 and 2) is a resonant thermo-fluid oscillator that pressurises water by the Joukowski effect. It has no precision parts or sliding seals and can be made from aluminium and common plastics using sand-casting, vacuum/blow-moulding and extrusion. It is robust, field maintainable, and can operate with solar or biomass heat sources. It is readily convertible to operate with other mechanical power sources such as wind, potentially unlocking un-subsidised drip-ir rigation for millions of smallholders worldwide. Thermofluidics has repeatedly demonstrated a NIFTE capable of outputting up to 60W, and a DAHR with hydraulic efficiency greater than 80%. This has been done with dirty and aerated water over multiple run-hours. The aim of this project is to de-risk Thermofluidics' technology to a stage where trade partners will invest in the tooling and supply chain management needed for a pilot production run and trial product launch. This will be address ed through developing world field trials of up to 20 prototypes in a range of open wells and boreholes down to 3 diameter, based on a single modular set of parts. Each prototype will be built to satisfy a production cost target competitive with treadle pumps.
