British engineer works to secure cost effective tidal power

23.11.2004


A British engineer believes he can secure cost effective tidal power by innovatively placing existing turbine designs inside large bore underwater pipes. Don Cutler’s view is that it’s best to use everything that’s standard. "You don’t re-invent the wheel you improve it."

"Sea water is a most aggressive environment, but using modern materials like carbon fibres, and Teflon, are about the only clever things about my design," he says. Cutler’s design is specifically aimed at taking advantage of straight tides. "With a tide running at 5-6 knots you can get all the power you need," he says. Cutler plans to use oilrig technology to secure his pipe based turbine structures to the seabed. "In order to maximise the tidal power I have five long tubes leading to the turbines, with fish deflectors," he says.

His idea is to prove his concept with a 50ft (15.24m) long pipe, which would be 5ft (1.524m) in diameter. He believes this would produce 1 kilowatt of power. Scaling this up to a pipe with a bore of 100ft (30.48m) would generate 6 megawatts of power based on peak spring tides. Cutler thinks, on average, though this size pipe would generate between 1 and 1.5 megawatts. "Once the water is in the pipe it has nowhere else to go. You need the pipe to constrain the water," he says.



Cutler, who founded the former multi-million pound Weymouth-based engineering company Tekflo, has a history in marine design. Tekflo developed equipment for water systems and North Sea oilrigs, and Cutler sold the business in the 1980s.

Cutler entered the world of tidal power engineering because Portland Harbor, in Dorset where he lives, was the proposed site for a wind farm. The plan was to locate the wind farm on the harbor and not 10 miles out at sea which Cutler believed would have been a better option, so he decided to design an alternative. He also argues tides are predictable whereas wind isn’t.

Cutler is looking to form an association with an existing company that has some experience of securing the finance for such projects.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
