Elemental Energy Technologies Ltd (“EET”) has been formed to hold
and commercialise a portfolio of provisional and patent pending
applications, research and proprietary know-how for its revolutionary,
environmentally-friendly, marine Vortex Reaction Turbine
EET has developed a true 3rd generation (“3G”) tidal energy
technology and named it the SeaUrchin. A turbine that is scalable and
can be optimised to operate in a very wide range of flow rates (as low
as 1.5 metres per second) making it deployable in the greatest range of
locations around the world. This feature alone represents a major
technological advantage over other tidal technologies that are
dependent on much higher flow rates to operate efficiently and so have
very limited deployment options by comparison.
It has been developed to harness the virtually inexhaustible kinetic
energy of free-flowing ocean streams, tides and flowing rivers by
exploiting the underlying principle and raw power of an ocean
whirlpool. It harnesses up to four times more power and is up to
70% more efficient than conventional “propeller” driven, marine
generators commonly in use and under trial today.
The SeaUrchin™ can be mass produced from proven, inexpensive
materials and components used by boat builders and marine electrical
equipment manufacturers. Importantly, it has only one moving part and
is expected to be around half the cost of competing marine generators
to manufacture, install and maintain.
How does the SeaUrchin work?
The gravitational pull of the sun and moon regulate the earth’s
tidal flows like clockwork: powerful, dependable and predictable.
And rivers flow under the earth’s gravitational force to the sea.
Today these massive and reliable energy resources can be tapped to
Nature is the inspiration for the SeaUrchin™, by mimicking a
powerful ocean whirlpool to harness the vast hydrokinetic energy in
tides, ocean streams and rivers and turn it into clean, reliable and
The SeaUrchin™ is simple in concept, elegant with its single moving
part, and practical in its scalability and efficiency. Tidal
power generation is now a reality; it has arrived and it will change
the way the world is powered.
