• Water is much more dense than air. With dams, water flows may be mined for energy using water analogues of AWECS.
  Paravanes or water kites using in various ways have proved efficient energy mining devices.

• River flow, creek flow, drain flow may be mined using hydroTurbines tethered to bottom or side terrain. Water kiting or paravaning tactics can "fly" turbines to flow center.

• Think reverse of propulsion of boat. Tether turbine in flow and gain energy for immediate use or for charging energy storage system.  Village entrepreneurs?
• Wind can store water to high head; that high water head can run water turbines at need time. Small or large scale is available.
• There are many patents covering water turbines for small and large. Hikers can carry a water turbine for charging batteries.
• Huge tidal flows are being mined using water turbines, both fixed style and tethered paravane style.
• Debris guards, fish guards, people guards are considerations.
• Fouling by life growing on parts of turbine are a challenge. Consider using part of the gained energy to heat the turbine to keep life from growing on the blades; other methods and material treatment are considerations.

In the drive direction (not generating) consider electric ships, electric hang gliders, electric trains, electric submarines, etc.  Tethering such systems in a current can be studied for the generation of electricity.  The advent of superconductor technology is changing the game in some sectors.

The great rivers & tributaries seem to be the focus of easily available & fairly reliable alternative energy. We know of good nature friendly ways to tap such currents at low cost without traditional dams (see below). Ocean currents & seasonal winds are generally more difficult opportunities, but there are exceptions. There is an easterly equatorial jet-stream at mid-altitudes overhead that might prove a great resource as our field matures. There are seasonal winds, sea-breezes, & nocturnal land breezes at low altitude whose intermittent but predictable winds can serve small flexible applications. Developing a pilot project to tap river-flow would be good demo of practical alternative energy for the Nigerian case. The following video clip shows a very basic tiny demo of an "advanced" low-current concept that can scale greatly- http://www.energykitesystems.net/DaveSantos/spiraldc.mpg        ds 2010-03-25
