• OTEC is a very promising technology for a host of reasons.
  • SWAC is a tremendously simple technology that can offer enormous savings.
  • LTTD has fantastically low maintenance requirements and uses relatively little energy to desalinate water.
  • The rigid pipe is exclusively responsible for the lack of development in OTEC, SWAC, and LTTD!
  • If a replacement for the pipe could be found that could be demonstrated to be cost effective on a small scale, investors would invest.
  • There would be no further obstacle to cost-effective OTEC. OTEC could lead the transformation to green energy.

Hose-based OTEC

The use of a turbo-pump makes it possible to use hoses without any need to use electric motors in deep water.

Hoses are used extensively in offshore oil and gas applications.  An impressive range of products can be found on the internet, including protective covers and floats.  We have demonstrated the ease with which 30 cm diameter hoses can be installed at sea.  The advantages were obvious; hoses are flexible and can be coiled.  They are easy to transport.

Hoses can naturally find the most hydrodynamic position if they are allowed to.  They work particularly well underwater where the weight of the water is negated.  The fact that hoses can do this, makes them perfect for delivering deep sea cold water.

The turbo-pump system

What’s so good about the delivery method?

The new method makes it possible to use hoses to deliver deep ocean water. Hoses massively simplify the deployment of long lengths of tubing. Thus we can offer low cost, small-scale OTEC, SWAC, and LTTD systems.


• NEW OTEC is now cost effective on small scales, meaning that opportunities for smaller projects with much lower investments are now possible.
• OTEC and SWAC developments are now in crowdfunding range.

Large diameter hoses



Small island nations are our core market area. These islands are the best locations in the world for OTEC, thus sitting on “a clean energy oil well.” Existing OTEC plants are not readily suitable for these small islands. Our new range of products is.


Institutional investors must see “bankability” before investing.  OTEC parts are bankable products, already produced in phenomenal quantities.  The alternator and turbine for example, could already be purchased in quantities comparable with the global wind power installation rate.  The parts are small, they can fit into ordinary buildings and onto ordinary trucks.  The background investment required is minimal compared with the early days of solar PV and Wind power.  The background science is 300 years old.   OTEC can make a significant dent in fossil fuel usage with out the long winded R and D path of other technologies.  It’s ready for sale now and competitively priced.
