Manchester develops new wave energy device: The Manchester Bobber

06.09.2005


The University of Manchester and the University of Manchester Intellectual Property Limited (UMIP) in partnership with Mowlem plc and Royal Haskoning, are developing an innovative and patented new wave energy device known as the ‘Manchester Bobber’.



The device will be showcased at the New & Renewable Energy Centre (NaREC) in Blyth, Northumberland, on September 19th (Press Invitation below).

The Manchester Bobber’s inventive features utilise the rise and fall (or ‘bobbing’) of the water surface. This movement transmits energy, which is then extracted by the mechanics to drive a generator and produce electricity.


The vision is to have a series of Bobbers working together to generate electricity. One concept which is currently being explored is the use of decommissioned offshore rigs as platforms for the devices.

Professor Peter Stansby, co-inventor of the Manchester Bobber and Professor of Hydrodynamics at The University of Manchester, said: “Offshore wave energy represents a substantial concentrated ‘green’ energy source for an island state like the UK.

“Energy from the sea may be extracted in many ways and harnessing the energy from the bobbing motion of the sea is not a new idea. It is the hydrodynamics of the float employed by the Manchester Bobber that provides the vital connection to generating electricity”.

The Bobber’s unique features include:

The vulnerable mechanical and electrical components are housed in a protected environment well above sea level, which makes for ease of accessibility.

All mechanical and electrical components are readily available, resulting in high reliability compared to other devices, with a large number of more sophisticated components.

The Manchester Bobber will respond to waves from any direction without requiring adjustment.

The ability to maintain and repair specific ‘bobber’ generators (independent of others in a linked group) means that generation supply to the network can continue uninterrupted.

The initial concept for the Manchester Bobber was conceived in January 2004 via a 12 month Carbon Trust award. The design, development and testing of the device has been carried out at the University of Manchester led by Professor Peter Stansby and Dr Alan Williamson.

Phase One of the project (testing of 1/100th scale working model) was successfully completed in January 2005. Phase Two, which is commencing now, involves a 1/10th scale device that has been constructed and will be tested at NaREC (the New and Renewable Energy Centre) over a two week period. Mowlem plc and Royal Haskoning are also developing and costing conceptual designs for a full scale platform. Phase Three will involve a full scale prototype being constructed and tested in parallel with detailed costings and engineering design for the optimum full scale concept from Phase 2.

The project team see the Manchester Bobber as a key international development at the forefront of the renewable energy sector. Dr Frank Allison, Assistant Project Manager from University of Manchester Intellectual Property Ltd (UMIP) said: “We are really excited about the potential of this project and can’t wait to get the prototype Manchester Bobber constructed and tested over the next few weeks, it will also be an ideal opportunity for people from the industry to come and witness this principal milestone and important achievement.”

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
