Start-up launches to bring affordable, efficient wind power to the masses

(PhysOrg.com) -- Totempower Energy Systems Ltd – a cleantech start-up which aims to create small-scale wind turbines that are cheaper, more efficient, and easier to install and maintain than current models – has launched, with backing from City University London.

City has granted an exclusive intellectual property (IP) license to and taken an equity stake in Totempower. The company will focus on the fast-growing micro-generation market, developing wind turbines for individual households, small businesses and communities, based on an advanced University aerodynamics patent.

It aims to enter volume production by 2012, delivering turbines that provide a much quicker return on investment for owners – both through cost savings and by selling surplus power back to the National Grid, under the Government’s feed-in tariff scheme.

The company was founded and is being led by Wolf Dietrich – an experienced entrepreneur and Executive MBA graduate from City's Cass Business School – who is backed by a team comprising University engineering and business expertise, as well as cleantech industry specialists.

Dietrich says: "Renewable micro-generation has the potential to cut emissions and introduce greater security to the UK’s energy mix. But, despite financial incentives from Government, consumers remain deterred from investing in their own technology, because of the initial outlay and the difficulties of ownership. Our aim is to address this issue, by making a wind turbine that is as simple to own as a gas boiler.”

At the heart of the new turbines, is the patented system known as the Passive Air-jet Vortex Generator (PAVOG), which was developed by Dr Simon Prince, Senior Lecturer in Aeronautical Engineering at City. This low cost technology increases the aerodynamic efficiency of turbine blades, enabling them to harvest more energy at lower wind speeds, whilst maintaining optimum efficiency in windier conditions.

Prince says: "City has a one hundred year heritage of teaching and research in the field of aeronautics. We are now exploring ways to use this experience in related areas, with wind and wave power being a prime example. We look forward to taking PAVOG to market via Totempower and making a real difference to how energy is generated tomorrow."

With significant testing already completed at the University, Totempower's focus over the next year will be securing additional funding for final prototyping and putting two turbine models into production – a 2,000 kWh pa version for individual households and a 15,000 kWh pa version for commercial or community use, with an average return on investment of around six and three years, respectively.

affordable, efficient wind power


oxymoron and a basic contradiction in terms "affordable" and "efficient".

By definition "wind power" is hugely inefficient. A large virtual wind farm will have a large potential energy output, but its average output will be small.

Better to build a single 1GW fission plant, than a 20GW wind farm that averages 1GW of output.

Shootist, you declare that it is "better to build a 1 GW fission plant than a 20 GW wind farm". You should reconsider this statement especially if you are talking return on investment. Compare both systems; include ALL future costs for each scenario. Don't forget the cost of operating, protecting, maintaining, and decommissioning the nuclear plants. Plus the cost of containing radioactive waste for more than 1000 years (Unless you know of a miracle process to get rid of it cheaply). And how long does it take to build a nuclear plant? Please do some honest and encompassing reality checks before publishing such opinions.

ThinkFirst, where did you come up with 1000 years?

Perhaps you should research the inverse relationship between intensity of radioactivity and half-life. Because the truth is that spent fuel rods only need to be sequestered for a mere handful of decades before they cool down to the point where they can be handled using much more conventional means.

6 year recoup is still too long for consumers, i want to save NOW like in next month, ok, 3 years max

Plutonium 239 has a half-life of approximately 24,000 years. That means that after 24,000 years half of the radioactivity contained in the plutonium will have decayed. However, the hazardous life of radioactive waste is at least ten times the half-life, therefore these wastes will have to be isolated from the environment for 240,000.

Maybe you have a nice big basement they could leave it in?

@Dually

You are joking right? I hope so. Im not anti nuclear or anything but come on. Maybe you should read this.
