Ultracapacitors

A battery stores energy chemically, while a capacitor can be said to store energy electrostatically inside an electric field.

Cooling: Off-Grid Energy Options

If you are in a remote location without access to grid electricity and you need refrigeration, there are a number of technologies you can use.

Audio-Visual Off-Grid Energy Options

As rural people increasingly demand these services, there is correspondingly rapid growth in demand for audio-visual equipment in off-grid rural areas.

Pumping: Off Grid Energy Options

In rural areas without access to grid power, water supply experts may not have sufficient energy knowledge to select the most appropriate power source.

Magnetics and Gravitics

New energy researchers and theoreticians think that they may open a door to bountiful energy for everyone with few environmental impacts.
