Plastic Micro Wind Turbine Available for Sale

Two of the biggest hurdles for using wind power have been cost and the need for strong winds. A Hong Kong businessman/inventor has found a way to overcome those problems with plastic, bringing the generation cost down to around 1 cent per kilowatt-hour -- the cheapest wind power system available on the market.

The inventor, Lucien Gambarota, sought to find a wind energy solution that could be feasible and affordable for remote third world villages and urban settings, where towers are not practical or allowed. The typical wind speed in such settings is between two and seven meters per second.

The return on investment is between three and five years.

"Motorwind power generation starts with 2 m/s wind speed but it starts to be economically viable for winds of at least 4m/s if you are concerned by pay back time." It can be installable anywhere due to the modularity. The size of Motorwind can be adapted to the available space and the energy required. The design simplicity and components used make the installation and maintenance very easy for anyone. The simplicity allows very low manufacturing costs and therefore very low retail price." [1]

Feb. 2, 2008

On Feb. 2, 2008, Lucien Gambarota replied to someone inquiring about urban installations:

Send me a picture of your installation with the obstructing buildings around; [as well as] wind direction and wind speed data.

In some area the wind direction is changing all the time. We have refused quite few installations because of that.

For each installation, we have a site visit to determine if the location is suitable.

I have attached [below] a 500 turbines installation that is right in the most residential place in [Hong Kong], and no neighbors have complained after 4 months.

HSBC Installation

On Feb. 3, 2008, Lucien Gambarota wrote to PESWiki:

The HSBC installation will be commissioned in the next weeks.

We need to either remove or install higher the lowest rows of turbines. There is a big difference in wind speed from the first row and the top one. When the top row is collecting approx 6 to 7 ms wind speed the first row only collect 2 ms. There is obstruction from the wall surrounding the roof top and it creates a kind of no-wind zone.

Let me modify the installation this week and I will supply all data.

Motorwind micro turbines

Motorwind micro turbines can work in wind speeds of only 2m/second. Their light weight, small size, and flexible configuration allows them to be installed in both urban and rural environments, for individual or corporate use. Motorwind turbines give users a new option for efficient renewable energy and therefore reducing their impact on the environment.

Twenty turbines per system has been found to be optimal, and spans about 1 square meter, with each rotor having a diameter of ten inches. Such a system, including a generator and frame, is presently priced at $200, though Gambarota would like to see that go down to $100 in economies of scale. The customer is expected to procure the batteries, inverters, and regulator. The system is expected to last 3-5 years.

The energy generated from such a system is, of course, dependent on the wind, which is quite a bit lower near the ground.

Chart is for 1 square meter of turbines (20 turbines of 10" diameter each).

Wind speed electricity
5 m/s 15 Watts
6 m/s 30 Watts
8 m/s 65 Watt
10 m/s 125-130 Watts

A wind speed of 2 m/s will generate 15 Watts, which a wind speed of 8 m/s will generate 64 Watts, and a wind speed of 10 m/s will generate 125 Watts. The energy generated goes up as a square of the wind speed.

The turbines work in harmony on their stand. The tined gearing between them does not result in very much frictional loss inasmuch as they are being acted upon by essentially the same force of wind simultaneously. The losses from transmitting the rotational energy to the generator, which is attached to only one of the networked turbines is going to be more significant, but not to an unworkable extent.

The turbines are designed to withstand winds as high as 50 m/s, such as is found in a typhoon.

One of the down sides might be the visual appearance. This can be addressed by placing the turbines behind a grill. Alternatively, a large array could be used for advertising, each turbine being colored as a pixel in a large matrix.

Oil Comparison Anecdote

One kilogram of oil burned yields 4.5 kilowatt-hours of electricity.

One kilogram of oil turned to plastic makes one microturbine that can generate 4.5 kw-h of electricity each month, lasting 3-5 years, and can be recycled for hundreds of years.

Independent Testing

For the past five months (as of May 5, 2005), the motorwind turbines have been underging testing by the University of Hong Kong, including wind tunnel testing. "The data are very promising", says Gambarota.

The theoretical maximum efficiency of wind turbines in harnessing wind energy is 44.25%. The MotorWind design is measuring close to 44% efficient, very close to the theoretical maximum.


On April 19, 2007, Lucien Gambarota provided the following self-evaluation of this MotorWind technology according to the 10 criteria set forth by the New Energy Congress.

MotorWave Ltd

Company formed to feature renewable energy technologies developed by Lucien Gambarota

  • Motorwave is a unique technology that has been created and developed in Hong Kong to tap the power of wave motion in order to make electricity,desalinated water and hydrogen. Anywhere there are waves.....there is power! Have built prototypes, from which they have collected data to estimate that this system could produce energy at 0.15 cents / kw-h. Presently they are waiting for funding to proceed futher.

The company expects to turn over US $25 Million in the first year. "We're hiring people every day." Within a year, they expect to have 300 people employed in Hong Kong and 2000 worldwide.

Inventor: Lucien Gambarota

50-year-old Lucien Gambarota has invented a number of renewable energy devices, including exercise equipment that doubles as electricity-generating equipment.

Born in 1957 in Italy, Lucien studied physics and chemistry in a French university. He worked as an international buyer for 4 years for the World's second largest retailer. He moved to Hong Kong in 1987 and opened a watch factory at that time. Has been doing private researches in many fields for more than 15 years, and has designed or discovered many consumer products. He invented and developed Motorwave technology and Motorwind technology .

He also developed the California Fitness concept of harvesting human energy during work-out.

Lucien became interested in renewable energy late 2004 and has since registered several patents.
