China here we come!

We gaan woensdag al! Ons vliegtuig vertrekt om 18.30. Om een beeld te krijgen van wat Oskar daar tentoon gaat stellen hierbij het persbericht:

Press release
Utrecht, 16 April 2010

Wind Turbine Car through the air
Participation in the World EXPO in Shanghai

World EXPO
The theme of the World EXPO is “Better city, better life”.
The World EXPO is held from May 1st until October 31st 2010 in Shanghai, China.
The architect of the Dutch pavilion ‘Happy Street’ is John Körmeling.
He asked Oskar de Kiefte to exhibit the Wind Turbine Car at the expo. He also gave de Kiefte the assignment to make a square, electric car which makes the Rietveld Schröder House bigger when it is parked in the corner of the house. The Rietveld Schröder House is one of the houses in the ‘Happy Street’.

Wind turbine car
It is a vehicle which uses the wind power at the front of the car. There is a relation between the air resistance and the wind power which has to be generated, regardless of the speed (E=mv2). In short, a wind turbine which is 1/3 the size of the vehicle can neutralize the air resistance completely.

There is another positive power: the effect from the air flow behind the wind turbine. The lee behind the turbine is three times the size of the turbine, in other words, exactly the size of the body! Besides, there is the rolling resistance from the wheels and the axles. Another opposed force: the force on the attachment points of the wind turbine.

The principle can work even better. It is imaginable that the air in the turbine accumulates and causes an overpressure. This stagnates the flow of air and the effects of the turbine. To prevent this stagnation, de Kiefte used Fan Shaped Wheels to create suction /a vacuum force. This principle can be compared with the operation of a TWECS-turbine which gets 200% efficiency from the wind.
(TWECS = Tornado Wind Energy Conversion System)

A car is parked approximately 22 hours a day. When the Wind Turbine Car is parked, the turbine is placed in a way that it charges the batteries, regardless of the wind direction. This means that the car is completely self-supporting.

The design supports the idea. A simple and functional design makes the function of the car clear. For example, the wind turbine is fixed between the front wheels and in front of the body. The consequence is a completely new body-layout, which provides new opportunities.

Oskar de Kiefte created a horse-shoe shaped beam round the bottom. This is an aerodynamic shape which is so strong that it can hold the wind turbine as well as the hydraulic front wheel suspension. Because of the simple, half cylindrical shaped body it is possible to make a sliding door, which opens by pushing it up, in the rounding of the body.

De Kiefte has worked together with another exhibitor, Frits van Breemen Schneider. Van Breemen Schneider develops airplanes and electronics. He changed the principle of the electromotor and he invented a small electromotor, used for cars, with a very high efficiency. He will build this 600 V-system into the Wind Turbine Car.

In conclusion, the car is going to be great!
An innovation with a refreshing exterior.
You would almost think: “Here is my space Age again”.
An example and experiment to use aerodynamics in another way.

Planning
Both the cars were put on transport to Schiphol last Tuesday. They were flown to Shanghai just before the volcano in Iceland erupted.
Oskar de Kiefte is in Shanghai from April 29th till May 18th.
The opening from the World EXPO is at May 1st.
The Dutch National day is at May 18th.
I hope to meet you in Shanghai.

Yours sincerely,
Oskar de Kiefte
