Michigan, U.S. officials look to small country that has welcomed alternative fuel for tips to help it catch on here.

Great if the world largest oil addict could follow Swedens example!

at the first moment it seems to be great.. but as you know a great amount of the ethanol used in Sveden for producing E85 comes from Brasilia via ship.
And there the production of ethanol is not really ecologic.

In my opinion the better way for the U.S. (and us, too) must be making the consumption of the cars leaner!

its much more necessary to force the research to develope new and cheaper ways to produce ethanol or other ecological fuels. one way will be the use of bacteria instead of yeast.

here is a link to an article (in German) about a company in Canada, who hopes to produce ethanol for a max. price of $0.25 per Liter.

The company was founded by the indian IT-Milliardär and Sun-founder Vinod Khosla and is named "Coskata".

GM bought some stock papers of that company and made a strategic partnership contract.

Modern ethanolproduction in Brazil from sugercane is from an ecological point of view one of the best in the world reducing CO2 emmissions to 90-100%! The ethanolplant use the rest the sugercane (bagasse) to heat the stills (steam) and electricity so they make not only ethanol but also clean electricity which can replace fossil fuels in other electricity plant.

The (humanitary) working situation in older not meganized sugercane fields sometimes needs much improvement, just like coffee, banana, cacao and many other landworkers in south-america.

In Sweden there is also a ethanol plant (agroetanol) that uses wheat (what? but that is food, yes but they use inferior wheat, from not so good crops unsuitable to make flour of) which is almost as good as Brazilian ethanol, this is because they do not only make ethanol from the wheat, from the rests hey also make "Futterkuchen" for cows (in stead of imported soya) and are going to make biogas from the rests as well.
Biofuel is also used to heat the stills.

Another thing is that we want cellulose ethanol from restsstreams, but it is good that we already have an infrastructure, pumps & cars once (hopefully soon) that production is going into large scale.

There is also the possibility to reformulate different kinds of biogas (methane) by adding hydrogen.
The stupid idea of gaseous hydrogen or biogas in the economy and in vehicles, might get an cheap and non leaking solution now by (if large quantities of hydrogen and/or biogas ever will be an option) using it to make a simple and environmentally friendly, liquidous fuel, ethanol!

We just have to get rid of the moneyspending and developing postponing (of more promising technologies such as lean running Otto-engines on alkohols) fuelcell utopist first...

This was news or?:
Citat:
Last year, Ford Motor Co.'s Volvo unit and a U.S. hedge fund invested $10 million in an experimental cellulosic ethanol plant in Sweden.

i do not see BRA in the leading role. Why should other countries repeat the faults they make in BRA? (although they do.....corn in USA)

monocultures of what ever to reach one target is not the right way. Here in my opinion Brasil is not on the "good side" actually. burnig down the rain forest to get space for sugar canes is not okay and can never come into a leading role.

Who says Brazil is burning down rainforest for sugercane? This is really total nonsense, the sugercane does not even grow on the same latitude as the Amazonas, sugercane production fields are at least 200 km's south of it!

One might argue that the sugercane production is pushing other agricultural production (like soyabeans, palmoil or cattle) into the rainforest, but that is not how it works either, see for example what a dutch professor and researcher in tropical agriculture says about this.

I might also add that off Brazils land used for agriculture less than 1% is used for sugarcane production. Half of this sugercane production is used för sugarproduction and half for ethanol production. In all less than 0,5% of Brazils agricultural land is used for ethanol production and bio-electricity.

Rainforest is cut down for timber, soy bean prodcution or simply to grow food for the local inhabitants.

Another possibility to prouce ethanol is to take tubes of plexy glass, fill them with water and let the algae grow. The algae then gets pressed out, the "oil" beeing used as a "plant oil" substitute oder processed to biodiesel and the rest beeing fermented to produce ethanol.

There is a small company in Germany already doing this.
