Our Kite Technology

The KPS technology has been researched and developed since 2011 by a team of highly experienced engineers. This is how it works.
Two kites are flown at any given time – this allows one to ‘rest’ while the other one generates power.
Phase 1:

The kite is programmed to fly in a circular direction, following the path that the tip of a wind turbine blade would make. The flight speed is high – over 100mph in 20mph winds.

Strong aerodynamic lifting forces are produced by the wing of the kite, and exerted against its network of bridles.

The tension causes a line to be spooled out rapidly by 100-200m from a drum on the ground, which is connected to a generator – thus creating energy.


Phase 2:

The first kite must now retract to its starting position, consuming the minimum amount of energy.

We change the pitch of the wing, as this will minimise aerodynamic resistance, and the kite exits its generating flight pattern, gliding back towards the starting point.

Line tension is reduced by a factor of 10 or more, resulting in a net energy gain during the cycle.


Why we use a twin-kite system

The KPS cycle has two kites flying in the same airspace at any given time, so that while one is generating power, the other is being retracted.

Energy production is therefore continuous, and the alternator is kept rotating at optimal speed.

Our patented system design

We have designed our system to prioritise efficiency and reliability.

WE USE TWIN KITES: they share a common foundation and one generator

WE CAN EASILY MAINTAIN OUR SYSTEMS: all components are serviced at an accessible height.

WE USE A PATENTED MATERIAL: this helps to minimise drag and maximise yield.

WE HAVE CONTROL: we can programme the kites to fly high above the ground

WE DON’T NEED EXTRA POWER: our technology is grid compliant.

WE USE SYMMETRIC KITES: this enables the kite to achieve the circular path with very little energy required to actuate the wing control mechanism.

Easy operation and maintenance

A significant problem that conventional wind energy faces is access for maintenance. At KPS, we have ensured that emergency operations and repairs can be swiftly managed, by designing an easily detachable mooring system.

This means that the maintenance can be carried out away from remote locations – whether it’s an onshore or offshore problem.
