The Product

How we harness the earth's rotation to generate power

At a glance

The KCT is the world’s first patented vortex turbine, operated using the spin as distinct from the fall of water, in the waterway, reservior or on land.

The KCT harnesses the energy in a vortex, drawing from the Coriolis Force to produce approximately 27% more electricity when combined with a conventional turbine, as revealed during proof of concept testing at Kalorama.

The KCT has been reviewed and endorsed by Dr. Harry Schaap, Federal Advisor for Renewable Energy. In turn Austrade has endorsed The KCT and included it on its Clean Energy Export Directory.

Features & Benefits

Box Image

On and off grid

You can provide power to the grid or operate KCT off-grid in combination with power storage, or both.
Box Image

Multiple placement options

Multiple KCT installations can be installed either in parallel at one junction or in a series along the canal.
Box Image

Secure and unobtrusive

KCT blends into the natural background and is very unobtrusive. In addition, it is easy to secure and monitor.
Box Image

Standalone or hybrid sources

KCT is modular in design and works great alongside other sources such as solar installations or diesel generators.
Box Image

Offsite, on bank, in waterway

An installation can be located practically anywhere: on a diverted canal, on a bankside or inside the waterway.
Box Image

No footprint, fully recyclable

The entire KCT assembly is made of recyclable materials and its removal can leave no trace of existence at all.
Box Image

Above-ground or In-ground

You can install KCT above ground, or in the ground, depending on the site and other project requirements.
Box Image

On Site Assembly in 12h

For a prepared site it takes 12 hours to assemble for a KCT assembly, not including any optional concrete work.
Box Image

Low Maintenance

KCT operates smoothly for a long product life with minimal maintenance. Distant monitoring & standard parts are available.
Box Image

Supplement existing hydro

KCT can be retro-fitted to existing installations of various types in order to economically increase a site’s output.
Box Image

Portable and mobile

KCT can be transported on the back of a truck and lifted into place easily. This enables access to hard-to-reach sites.
Box Image

Long operating life

With a simple and rugged design, and very lengthy MTBF, KCT is supported by a 25 year warranty.

Marysville KCT Vs Conventional Hydropower

The KCT uses the flow not the fall of water, and can operate with a very low head, well under the 3 metre minimum required by conventional turbines to operate efficiently. Furthermore it does not interfere with the flow rate, which enables the system to be used sequentially in a waterway.

The KCT is especially designed for low head applications over traditional Kaplan and Francis type turbines, due to the increase in efficiency it provides; as can be seen on the graph.

At Marysville, the KCT hydro plant generated 550 watts using 110L/s of water flow with a fall of 0.6 metres. This equates to about 5 Watts per litre/second using flow only, not water pressure.
A turbine’s efficiency can be determined by the standard formulas, and the output identified in the graph was extrapolated from available data. However it should be noted a Kaplan or Francis turbines could not be installed and operated at the Marysville site with this low head.

  • Efficiency (%)

Standard Formula: Gravity * Head * Flow Rate * Efficiency = Watts Output
KCT: 9.81 m/s2 * 0.6m * 110 l/s * EFF = 550 watts. Efficiency = 85%.
Kaplan: 9.81 m/s2 * 0.6 m * 110 l/s * EFF = 180 watts. Efficiency = 28%.
Francis: 9.81 m/s2* 0.6 m * 110 l/s * EFF = 300 watts. Efficiency = 46%

Exponential power increase

The following KCT graph supports the proposition that vortex power is an improved form of hydroelectric production over conventional head of pressure hydrology. The graph shows that watts per litres/second and vortex power appears to increase in an exponential curve, as vortex size increases. The power does not appear to increase lineally, as the standard formulas would dictate.

With the KCT, power increases exponentially because the volume/mass increases exponentially with vortex size due to πr2 x depth. Accordingly, a vortex chamber of 2m x 2m = 6.28m3/tons whereas a vortex chamber of 4m x 4m = 50.24m3/ton.
