Large Scale Drip Irrigation Curtain

For large farms, current irrigation technologies are limited to two options: large sprinklers or drip irrigation systems. Each option comes with a set of problems. Drip irrigation requires tubes to be spread on or under the ground. The tubes can get plugged, become damaged by, plant roots, farm equipment and even animals.

Large scale solid oxide fuel cells made practical

PRACTICAL LARGE SCALE SOLID OXIDE FUEL CELLS Solid oxide fuel cells (SOFC) are extraordinarily efficient, regularly achieving fuel conversion efficiencies of 80% (heat and electricity). The pollutants from these electrochemical devices are almost zero and the CO2 discharged is about half of traditional power generating methods. Another compelling advantage is the ability to utilize many different fuel sources.

Low Height Hydro-Pneumatic Dam

Most traditional methods of producing electricity are too expensive to build and maintain for the many developing countries of the world. Although many of these countries have rivers that could be dammed for hydroelectric power the cost would be too great. In addition to the cost most of these rivers lack the height required for hydroelectric power.
