Topic: Ethanol fuel - page 2. (Read 1147 times)
Ethanol may be cheaper than gasoline, but there are drawbacks. Burning 1 gallon of ethanol fuel gives 34% less energy than burning the same amount of gasoline. Its energy content is about 70% of that of gasoline. Also, current version of the motor engines will need upgrades to make them work with ethanol fuel.
In Brazil, ethanol comes from sugar cane.
That's too bad.

I think one of the biggest problem is the used biomass which are mainly crops that we humans or farm animals eat.
We would need to cut our food to have fuel - atleast with todays technology.

Much easier industrially to produce methanol, or ethanol, from natural gas using a steam reforming process. The only thing that makes alcohol difficult to use as a fuel is the curious idea that it must or should come from biomass.

Not really. There's a lot of land that isn't farmed by anyone and is fit for biomass. The land in Eastern Europe and Russia is very cheap, if somebody wanted to produce biomass on a large scale it wouldn't be a problem there. I've even read somewhere that Russia is giving land for free if you're willing to cultivate it.We would need to cut our food to have fuel - atleast with todays technology.
i guess that could work depending on how much space and how good the land for farming is.
if its just replacing food for fuel production then it would be bad.

The simple answer is cost.
Cost comes out in two ways. The first is cost of production. On an energetic basis, ethanol is less energy dense than petroluem products like gasoline, so it has to have a lower volumetric cost of production to maintain parity. Given the ethanol technology currently available, the cost of producing the ethanol in most places is going to end up very near or at the current price of fuels from petroleum.

Even if the price is the same, it is most definitely worth it.
If you're importing all your petrol, you're esentially sending money away.
Once you produce your own fuel, you're creating jobs and payments that stay within your own economy with that same money you would anyways use on petrol.

I'v already heard about Brasil going completely green and independent with their fuel
However, recently I'v read some more about it
My country import 82% of its oil, and I'm pretty certain most of our countries are importing
With so many people in a bad situation I can't avoid asking the question how many jobs would transferring to ethanol based fuel instead of the imported petrol create? *metaphorical*
Our own farms with our own workers on our land producing our fuel, completely green and healthy for the planet
How expensive is it to transfer to the ethanol system?
Esentially ethanol fuel is cheaper than petrol
Why are countries that import oil not investing in this system that is cheaper and doesn't send your money outside the economy?
