Irrigation and hydroponics
Hydroponics is a method of growing plants in water instead of soil.
Hydroponic agriculture can recycle nutrient solution in the watering process; it needs about 1/20th the water while producing up to six times the yield in less than 1/3 the space and does not require soil or contribute to soil erosion.

Stirling motor also called Sterling engine
A stirling motor is a closed system that converts heat flow into mechanical work.
Most stirling motors can also work as a heat pump and convert mechanical work into heat flow (cooling and heating)

A Vortex Tube is a device with no moving parts that will convert a stream of compressed air into two streams; one hot and one cold.
It can produce cold air down to -50 degrees F. and hot air up to 260 degrees F, but is very energy consuming
