Bike Sailing 21st Century Innovation Or A Science Project Gone Bad

With ozone-layer depletion a great issue nowadays, inventors are developing new ideas. The transportation sector in particular is getting all the bad publicity. And as carbon monoxide emissions become the focus of tighter regulations both in the US and Europe, the race for eco-friendly vehicles is on.

One of the inventors who rely on the powers of Mother Nature is Vladimir Zam. His wind-powered bike is designed with a triangular sail. The big question is: how will the bike run?

The design for US Patent 6932368 calls for a sail attachment to be linked to the bicycle harnesses wind to move the bicycle forward. A wind receiving sail is available at the attachment, which can generate the wind needed to power the bike.

Would the addition of a sail attachment qualifies it an invention? It looks more like a science project gone bad. Seriously, the design for this patent is an awkward cross between a sail boat and a bicycle. Considering that the patent retains most of the features of a regular bike, the sail attachment just complicate matters. Whereas, people could simply rely on their two feet to forward a bicycle.

Imagine yourself driving this thing around in the middle of the metropolis traffic jam. That is provided you could survive peddling a long the streets without being dragged through your sail by speeding vehicles. On the upside, well you could make money using this bike to money. For instance, why dont you convince your local pizza delivery store to advertise on your sail. Youll just have to capitalize on your endurance and be able to bike for three acres or until you drop dead, whichever comes first.

So what do you guys think? Is this an innovative invention or just a product of a man having too much time on his hands?

Basic Materials Used In Making A Picoturbine Windmill For Your Science Fair Project

Magnet, copper wire, aluminum wire, screws and clips, cardboard, and wood are the basic materials to used in making your own PicoTurbine windmill science fair project.

A PicoTurbine is a small windmill structure functioning to produce a small scale electric energy. A windmill structure is a very suitable science project idea for renewable energy topics. It is an ideal science fair project because it can be built easily. The materials used to make such project can also be easily found in any hardware store. PicoTurbine windmill is basically made from the list of items below.


The magnet is basically used to attach with the rotor disk place above the wooden base of the PicoTurbine. It’s securely attached with a double sided tape to a thick cardboard to function as a rotor mechanism. When the rotor spins the magnet’s magnetic field will release enough voltage to light the light emitting diode or LED.

Copper wire

A copper wire is used as a pathway of the PicoTurbine’s electric circuit. It is generally used in building the stator segment of the turbine. It is also use to transport the voltage in lighting up the light emitting diode or LED. Expose the copper wire on the end of the coils with sandpaper. Remember to get rid of any enamel left on the copper to have an efficient stator.

Aluminum wire

An aluminum wire is used to assemble the base and yoke of the windmill. Wrap the aluminum around the dowel. Bend and loop the aluminum wire with pliers to form the yoke as well. The yolk and dowel can then be placed on the center of a wooden base by screwing it with Philips head screw.

Screws and clips

Screws and clips are essential bearing parts that are used in assembling the different segments of a PicoTurbine windmill. A Philips head screw is specifically used to attach the yoke and the axle of the windmill. Retaining clips are metal clips that fastened the dowel to the rotor. Screws and clips are the joints and tendons of the whole PicoTurbine skeletal structure.


The cardboard is the base support of the paper blade and turbine patterns. A cut-out paper template is glued to the cardboard to give it more weight. A cardboard is also used to support the magnet and the rotor.


Wood is basically used as a foundation of the PicoTurbine. Since wood is a solid material and can easily be screwed, it is an essential base to hold all of the windmill’s parts. An 8? by 5? wood is the ideal size for an 8? PicoTurbine windmill. A half inch thickness of the wooden base is also a complementing support.

Prepare all the necessary materials completely before you will start building your PicoTurbine windmill. PicoTurbine windmill kits are also available in the market to ensure that you have all the materials that you need. Scissors, screw driver, and ruler are the tools that may come in handy.
