Steps Build Basic Bicycle Generator

Acquire a Motor – The first step is to acquire a DC motor for bicycle generator. This can be acquired from an old computer or printer. Motors are present in almost every electronic item. You can even go online and buy a new motor at an affordable price. Once you have acquired or bought a motor, you need to take off o-rings and plastic gears.

Mount the Motor – The next step is to mount the motor onto the back tire of the bicycle. This will allow the tire to turn the shaft of the motor. You will also need to put a sort of disc to the arm of this motor. This will allow it to touch the tire. It is always better to use big rubber discs as they provide good friction. The turning will cause voltage to easily come across the leads on this motor.

Basic Procedure for A Stationary Bicycle – First, let us talk about a stationary bicycle. If you are trying to build a stationary bicycle generator, you will have to build a stand too. This will make sure that your back tire is elevated. You should use a multimeter or voltmeter to measure the voltage your motor is producing when you are pedaling. Usually, this will be enough to power a small TV or charge a 12 volt battery.

The next step is to attach a voltage regulator to the leads of the motor, reaching whatever equipment you want to charge or run. If you don’t use a regulator, batteries can explode. For those of you who don’t know, voltage regulators are small chips. They can be easily soldered onto a circuit. It is quite simple and easy to acquire a schematic for every voltage regulator. You can get them at an electronics store or online.

Once you have used a voltage regulator with motor for bicycle generator, you can feel free to run any compatible appliance. You can get around 100 to 200 watts of power. However, you need to use the right kind of motor.

Basic Procedure for A Moving Bicycle – On the other hand, if you are trying to build a generator on a moving bicycle, you just have to mount the battery holder near the back tire. It will be better if you mount it just above the tire. This way, you will not have to use long connecting wires. You also need to make sure that the wires are tight and don’t get caught up in the tire. The rest of the steps are the same as a stationary bicycle generator.

Alternative Fuel Cars

Above you can see obvious reasons why diesel engines are not healthy for the environment, or for your wallet. However, two different types of engines for cars are currently available on the market, and ready to be used by citizens all over the country. You have probably heard of a “hybrid” car by now, which is a car that uses an engine that utilizes both oil and electricity in order to power the car. It also uses a smaller engine with lighter parts, so that that engine does not have to work as hard in order to move the car. The electric motor helps to power the car, thus allowing the engine to work less hard and waste less gas. Also, the energy used when you brake is recycled and put into the battery in a hybrid car.

In an electric car, there is an absence of an engine altogether. The engine is replaced by an electric motor, much like the one in a hybrid car. This electric motor is powered by a set of rechargeable batteries, so it removes the need for oil completely. This is obviously a plus, since the car will not emit dangerous chemicals into the air, and you won’t have to pay a high price for gas. In fact, a full charge for an electric car is said to cost as low as $2.00 to $4.00. This is amazing compared to the almost $100 dollars you spend filling up your diesel engine car

Water Powered Cars

Did you know that water can be used to power cars? It’s true. The German BMW auto makers have already produced the world’s first hydrogen powered car. However, they only produced 100 of them. Can you imagine if they build more and these cars were on the road?

This initial model car is called the BMW Hydrogen 7, and uses the body of the 760i model. When you pop the hood on this car you will immediately notice it is different than a gas powered car. Under this hood are a gas and a hydrogen system.

The hydrogen power allows the car to travel 4.7 miles on a gallon of water. In the future these figures will more than double. For now, we still need duel engine cars because we refuse to completely give up our gas powered vehicles.

The greatest challenge in using water as a green energy source is in the engine. Hydrogen combustion engines are still in their infancy. The technology for such engines is less than 10 years old and still growing. Who knows where the future will take us.

In order to prevent evaporation, large 30-gallon, bi-layered and highly insulated tanks have to be installed in the vehicle. There is a danger of the water evaporating into compressed gas without these safety devices. Another safety mechanism is in the valves that open if the pressure in the tank exceeds 5 bars.

Due to the success of the BMW H7, the German company has come out with a new car that they call the H2R. Although water powered, we cannot take our garden hose and fill it up: these vehicles actually use liquid nitrogen as their fuel. Tests on this new car show that it can accelerate from 0 to 60 miles an hour in under 6 seconds. With a top cruising speed of 185.5 mph, this vehicle can achieve 285 hp. This is a remarkable vehicle that shows promise for the future.

The advantage to water over gas or diesel is demonstrated in the lack of harmful gases released into our atmosphere from water powered cars. Water also weighs less than hydrocarbon fuels and burns faster than regular gasoline.

Hopefully, water powered cars will be available to the public within the next 10 to 20 years. When more automakers decide they want to build green energy vehicles then we will see a dramatic change in what we drive today. Until then, we drive what is out there.

Electric Automotive Challenges

End of Life Battery Disposal: Where do all these batteries go with chemicals that are not so good for environment? Proponents say; it’s not that big of deal. Still, if old cell phones are considered hazardous waste partly due to the batteries inside, then car batteries which are much bigger with huge amounts of material are even more problematic.

Slow Growth: Currently electric vehicles make us such a small percentage of the total, that they are not making any real difference in the use of fossil fuels, so if that is the goal, it will take decades to achieve and need massive government intervention – hasn’t government intervened in the free-markets enough lately (Healthcare, Biofuels for instance) and how has that worked out for us?

Electric Automotive Rebates: When government gives rebates we all end up paying for it in higher taxes. If EVs cost on average $10,000 more, and we give rebates, we are subsidizing a sector over another sector, picking and choosing winners. It’s wiser to allow EV industry to pony up and find ways to lower prices to compete.

Electric Automotive Are Quiet: Proponents say that’s a good thing. But, tell that to the kid or cyclist that didn’t hear them coming and got smushed. Some EVs now have “sound” to alert people they are coming, and you can choose the sound you like, several options. That’s nice, but defeats the concept and/or benefits of such serenity associated with EVs. Sound also takes energy to make, ask any audio installer of sound systems for cars, often a second battery or batteries is/are added for larger systems.
