Global warming

[Lue C Fur]

Typical scumbag politician. Ethanol is worse for the enviroment but Al was OK with it because it helped him in the long run.

Former U.S. Vice President Al Gore reportedly has had a change of heart on Ethanol, telling a conference on green energy in Europe that he only supported tax breaks for the alternative fuel to pander to farmers in his home state of Tennessee and the first-in-the-nation caucuses state of Iowa.

Lucy:

I was joking on the post to Cheryl....but obviously WE cannot be too alert.

Where do you fly back and to? You mentioned an A300 once.

Ethanol itself is not the problem. Ethanol made from corn is the problem. Corn is a horribly inefficient crop to use for ethanol production, in terms of yield per acre. Sugar beets, hemp or even algae have huge potential as biofuel crops. They just dont have powerful lobbyists to promote them.

Corn is also a food crop.
Use it to make fuel and there is less to eat or to use as animal feed.

It takes 10gallons of water to make 1 gallon of Ethanol., also you go farther on 1 gallon of Gas (1 or 2 mpg less with Ethanol) and Ethanol has to be transported by truck since it so corrosive and cant be shipped in via the system that is already in place to transport gas. Knowing this you would think Al Gore would have really been against Ethanol...

Maybe if they use sugar beets, hemp, or alge then it might be better for the enviroment if it uses less water but its still ethanol and will still have the corrosive and MPG issue.

I read about a week ago that we will be going to 15% Ethanol mix next year...

And that's why Dwight Shrute has a beet farm !!

That is only true if the source crop for ethanol is corn.

As far as ethanol having less energy/MPG than gasoline, that is also true. However, gasoline is made from oil...and we are running out of oil. Ethanol is a renewable fuel, so in theory at least we could grow a virtually infinite amount of it since its energy source is from the sun rather than fossil fuels.

It is accurate to criticize ethanol generated from corn as being wasteful of land and water and food, but there are many other methods of making it that are far more efficient. And the technical issues surrounding ethanol storage and transport are all easily solveable if we as a nation simply made a commitment to doing so.

An ethanol engine can actually be far more efficient than a gas engine due to the fact that ethanol has a much higher octane rating than gasoline does. The fuel itself may have less energy, but in an engine with a much higher compression ratio (impossible to use gasoline in) that energy can be used far more efficiently. There is a reason why top-fuel funny cars use alcohol rather than gasoline as a fuel.

Interesting...sounds like much more needs to be done if we continue to go the Ethanol route. I think we should look more into nat gas for the time being since we have so much.

CO2 level not seen in millions of years


http://www.nytimes.com/2013/05/11/science/earth/carbon-dioxide-level-passes-long-feared-milestone.html

 

[Upsmule]

Carbon Dioxide currently at 370ppm, for it to be dangerous it would have to be at 15,000ppm. This could not be reached even if every fossil fuel was burned.

Thousands and thousands of studies show that higher levels of co2 are good for plants. Many scientists believe plants still aren't getting enough co2.

The NY Times? Ha!

"It symbolizes that so far we have failed miserably in tackling this problem,” said Pieter P. Tans, who runs the monitoring program at the National Oceanic and Atmospheric Administration that reported the new reading."

Damn....maybe if we hasn't been so gullible back in the 70's when the "facts" said there would be another ice age and global cooling?

Wow.....

Carbon Dioxide and global warming facts

Nice link, sure looks trustworthy. Do you have so much as a GED?

Can you link to say two scientific, peer reviewed papers proving your point, never mind thousands and thousands?

Why do you hate science?

 

[Brownslave688]

Maybe we are still coming out of the last ice age. Or headed for another large tropical period. Although our life cycles are relatively short earths is much longer. We still have a lot to learn.

RR.....that link couldn't be any less agenda driven than the NYT's no?

My simple point proven, thanks.

Seriously? The guy was asking for money, never mind the 80's web design.

Also, he's not a 'scientist'.

My state was covered in a glacier scientists say, several times over....what caused them to melt? Global warming?
