Can You Use a Green Energy Source like Water to Power a Car?

For more than a century, we rely on oil to fuel our cars. But did you know that the world’s oil is close to drying up because it is a nonrenewable resource? Well that may not happen tomorrow or next year but we are getting closer because of the demand in the world market. Why wait for that day when we can rely on a green energy source like water to power our cars.

Water can power a car? If you think that’s impossible, well it is already here but this is not yet being made on a commercial scale.

The German automobile BMW has produced the world’s first ever hydrogen powered car. While only 100 of these units were produced, you can already imagine if more of these vehicles are on the road.

The initial model namely the BMW Hydrogen 7 uses the body of the 760i model. Once you pop the hood, you will notice that the engine is different since it uses gas and hydrogen.

This just means we have not yet totally abandoned are dependence on gas. Given more time and money, the current 4.7 miles per gallon it can travel using water alone could hit double digits in the future.

The biggest challenge to using water as a green energy source as opposed to oil in vehicles is the engine. While there are cars around like the Prius which runs on electricity and gas thanks to fuel cell technology, the hydrogen combustion is less than 10 years old so you could say we are only seeing the tip of the iceberg.

To prevent the water from evaporating, this has to be stored in a large, 30-gallon, bi-layered and highly insulated tank so this does not evaporate into compressed gas. Another safety mechanism is the valves which are designed to open should the pressure within the tank exceed 5 bars.

With the success of the BMW H7, the company came out with a new car that is also partly powered by water known as the H2R. While we cannot yet put our garden hose into the fuselage to fill it up, this vehicle uses liquid nitrogen as a fuel.

Tests on this vehicle have shown it can achieve 285hp and reach a top cruising speed of 185.5 miles per hour. It can also accelerate from 0 to 60 miles per hour under 6 seconds.

But why use water? It is because hydrogen combustion is clean so it does not emit harmful gases into the atmosphere unlike cars that run on petrol or diesel that emit carbon monoxide. Studies have shown that it also weighs less than hydrocarbon-based fuels and burns faster than conventional gasoline.

So when can you expect to buy a car that uses water as a green energy source? Hopefully in the next 10 to 20 years. It is really up to the automakers because all we can do is wait until a better and clear car hits the dealership.

Right now, the best option we have are electric cars. Since its introduction in 1999, more people are using it because they don’t want to spend anymore for gasoline that could hit an all time high of more than $150 per barrel.

If water as a green energy source can be used to power a car, why don’t we do the same for solar power which has been around much longer?

How to Make Your Own Green Energy Source

Wouldn’t it be great if we can produce our own green energy source? If we can do that, we don’t have to pay electrical bills or gasoline anymore for our cars. While we can buy some of the equipment, the rest will have to be done on our own.

Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system yourself.

To have solar energy, you will need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The only difference with wind energy is that you need a fan. Once you have everything you need, you can put it all together.

If you are not skillful, you will be happy to know that some companies sell the entire system. By buying it from them and having it installed by their experts, you are sure that there won’t be any problems the moment you switch it on.

There is one more thing you need before you can use one or the two green energy sources. Before you buy the materials or the system, make sure you have a flat area that is about a hundred square feet or so because it occupies a lot of space.

For those who don’t have the space or the budget to use these two energy sources, another option is to create your own biofuels.

Biofuels are used in many countries and they get it from harvesting corn, sugar and other crops. Luckily, you don’t need a farm to produce it because you can also make your own using some recycled waste.

A good example of this is vegetable oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The next step is to remove the water also by boiling it again at 100 degrees for a short period of time.

We need to know the amount of lye present in the vegetable oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to produce sodium methoxide.

The process of converting used vegetable oil before it becomes a biofuel takes quite awhile and it must be heated the entire time. This is done so the fuel we produce is pure and only when this is achieved that we give it time to cool.

Just how much biofuel we make after all the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there is still some glycerin present, filter it again. From there, you already have your own backyard biofuel which you can use and even sell to those who are just as concerned with the environment as you are.

By making our own green energy sources, we make ourselves less dependent on gasoline in its various forms to power our heater, home or car. Why don’t a lot of people do it? Well simply because they don’t have the time to make it and would rather rely on someone else to do it for them.

What are the Advantages and Disadvantages of Using Green Energy Sources?

Today, we are now aware of the effects of global warming. Fortunately, it’s not too late and we can still change which is why many are pushing for green energy sources.

The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment. It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so.

Although green energy facilities are expensive to build, it requires less maintenance so you don’t have to shell out a lot of money to operate it.

It can also bring economic benefits to certain areas even boost tourism.

While these sound good, there are some who say that there are disadvantages to using such technology.

While green energy sources can produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity.

Building these facilities also requires a lot of land so we may have to cut on farmland which is what many are concerned about if more wind turbines are to be put up.

Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet. For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet.

But if you look at such arguments, places that cannot use one form of green energy source can be substituted for another. If wind turbines need more space, they can be installed near the coast instead of putting these on land. A study shows that you can generate more electricity while these are in the ocean.

While the weather is something we cannot control, it is not everyday that there is a weather disturbance so this too shall pass. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored.

The point is that there are ways around the arguments put by certain individuals which discourage the use of green energy sources. In fact, research is ongoing to try and harness other means to generate the power we need.

A very good example of this is called ocean thermal energy. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii.

In the US, only 7% of green energy sources are used nationally. This was much higher 11 years ago and if we don’t have to worry about the cost of oil or even reduce our dependency on it, we have to invest more in this clean energy.

We can get it from green energy sources such as biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it instead of relying on traditional non-renewable means to produce energy.
