Tidal power or tidal energy is a form of hydro-power that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are more predictable than the wind and the sun.

Tidal power or tidal energy is a form of hydrophone that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are more predictable than the wind and the sun.
- Potential: Worldwide potential for wave and tidal power is enormous, however, local geography greatly influences the electricity generation potential of each technology. Wave energy resources are best between 30º and 60º latitude in both hemispheres, and the potential tends to be the greatest on western coasts.
- One type uses floats, buoys, or pitching devices to generate electricity using the rise and fall of ocean swells to drive hydraulic pumps.
- A second type uses oscillating water column (OWC) devices to generate electricity at the shore using the rise and fall of water within a cylindrical shaft. The rising water drives air out of the top of the shaft, powering an air-driven turbine.
- Third, a tapered channel, or over topping device can be located either on or offshore.

Comments to Wakati : Keep food fresh using solar power by RS3686 by AV2698 :
Unlike a refrigerator, the Wakati does not control temperature and, therefore, cannot store fruit and veg for long-term periods. Wakati have shown that a one or two-day shelf-life in a hot climate can be increased to 10 days. In developing countries this can be significant because some food will not go to waste and some companies can even profit.
