As people on fuel alternatives, is a reflection of ethanol. There are many types of bio-fuels (ie, fuels that are not on the scarce natural resources), and ethanol is one of the most even in the most important fuels.
Hydrogen is one of the best sources because, as it is a lot, but there is still a long way before it a practical alternative. The electricity is limited, and so far it is only in combination with other types of fuels.
But ethanol seems to be a intermediate step between really cheap, and the availability of fuels such as hydrogen and electricity, our current use of fossil fuels.
The reason for the ethanol is used as an excellent alternative to fossil fuels because they come from sugar or starch in the production of cereals and sugar cane. Other fuels from plants, hemp, corn, potatoes, sunflowers, seaweed, rice, sewage and even cheese whey.
Unfortunately, at this time, ethanol is not their due attention, because the impression that it is much more massive the planet, enough plants for fuel our vehicles.
What is the eco-scientists need to do is stop taking into account the growth of plants for the production of ethanol, and not, as the waste of cultures (in collaboration with the waste from landfills) can help to ethanol.
Ethanol is the same type of alcohol, if you have alcoholic drinks. But it is not as simple as just dumping that bottle of vodka in the tank. And also it would not be cheaper than gas!
Ethanol burns cleaner than other types of fuel and its combustion produces no extra carbon dioxide. (He has some, but no longer, it would simply decomposition) and the water is also a byproduct of combustion of ethanol.
Another problem is that the transfer of the rotation of ethanol in the burning cars cars is that Ethanol destroyed some rubber or plastic fuel currently spreading in many cars. And because ethanol burns hotter, which will require some adjustments of the spark plug of the system in the vehicle. And in the colder climates, a system is needed to fuel in the cold.
In contrast to methanol, ethanol is not toxic (prolonged exposure to this no brain damage).
So, if ethanol is also why we are not in use?
One of the problems is that ethanol, is convinced that energy is more expensive to produce, for the same amount of fossil fuels, fuels derived. It is a subject with a weight of several pages, with his comments. But at the end of the day you should know that the answer is not entirely clear from one side to a crucial victory.
At the beginning is that the ramp-up for the reduction of current in the production of fossil fuels, any conversion of cars and petrol stations and car manufacturing facilities, equipment and fuel, the costs are enormous. Over time it can be useful, but the advantage of ethanol compared to fossil fuels is not of the people is not enough to make them act.
