Tidal power, which could make a considerably energy contribution, has long been the goal of scientists the world over. But while many have dreamed, few have delivered in harnessing the ocean’s strength. As a result tidal energy has lagged far behind solar and wind powers with typical barriers cited as cost, hostile saltwater environment and damage to existing marine life.
That could all be set to change thanks to a British start up, Kepler Energy, who have developed a brand new form of water generator harking back to a traditional water mill. It is predicted the cost of operating, building and delivering energy could be cheaper than that of wind farms and other renewable energy at present.
Costs will be cheaper than lagoons and in time we will be cheaper than offshore wind generation
“Costs will be cheaper than lagoons and in time we will be cheaper than offshore wind generation. Furthermore, investment risk is manageable since turbines are added incrementally to form the fence, with each one generating revenue as it is added.” said Peter Dixon, Chairman of Kepler Energy.
The Kepler patented ‘Transverse Horizontal Axis Water Turbine (THAWT)’ is able to operate in lower velocity and shallower waters than traditional axial turbines and the company are planning the process to ensure that it bears no significant risk to marine life and other users of the sea.
Each turbine is modular and can start producing electricity as soon as it is in position. As more sections are added the power return increases exponentially with a 10km run being likened to a small nuclear reactor.
Kepler are planning a trial 30MW tidal energy fence that will be located in the Bristol Channel, most likely to be located in the Aberthaw to Minehead stretch of water. They are hoping this will be operational by 2020/21.
Glasgow is to invest £1.3m on a city wide cycle hire scheme to appear before it becomes host to the 2014 Commonwealth Games.
The roll-out will see 150 bikes spread over 15 locations, with an ambition to have 400 bikes and 30 docking stations.
The operator role will go out to collective tender, while the city council will foot the £1.3 million capital costs.
The council said it expected it to be about £1.50 for two hours – presumably allowing users time to get up all those hills.
Council leader Gordon Matheson told the Scottish Herald: “”Cycling is cheap, keeps people fit and active, and is good for the environment. I am proud Glasgow is the first city in Scotland to launch such a scheme. Labour is committed to promoting cycling and I want Glasgow to be a city that is friendly to cyclists. This investment will provide an attractive option for people looking to travel quickly around the city. Creating a healthier, more active Glasgow is one of the key legacies of the Commonwealth Games. Bike-hire schemes are popular across Europe.”
Unlike the London system, and more like one in Frankfurt, Germany, the bikes will lock to ordinary bike stands, and users will use their mobiles to obtain the code to the bike’s lock.
Brian Devlin, the council’s head of land services, said: “It would be the intention to implement the Mach scheme in spring 2014, prior to the start of the Commonwealth Games.
“It is recommended the council agrees to underwrite this project at this time to provide a level of certainty to private sector tenderers that the council is serious about this project.”
But the city will be looking to Liverpool for advice, who have not yet managed to find an operating partner for a similar scheme, and Nottingham, where only one bike a day has been taken out in recent months.
I am a fan of solar power – 2 of my watches are light charged so it makes sense that bike computers follow suit since they are nearly always out in the daytime.
It’s not only a nice idea to think “green,” it can be downright beneficial at times, too. Vetta’s new Solar Flare cycling computer uses a traditional battery, but also draws power from the sun. So your battery will last longer, saving you money and keeping it out of the landfill.

Bikes are the future – if you live in a city you owe it not to yourself but everyone to get on your bike and use less car transport. A bike city is a friendly city. And if petrified about theft then get a Brompton and take your bike into places with you.
