At Scientists' gathering, biofuels - principally ethanol - were uniformly trashed

From New Scientist

The sun is a star when it comes to sustainable energy


In order for plastic solar cells with 8% efficiency to supply U.S. electrical energy needs, a land area of 58 million acres (shown as eight green blocks) would have to be covered by solar farms. The orange square in the California desert, however, could supply the state's needs with 1% efficient solar cells, and the nation's needs with 6% efficient photovoltaics. (Alivisatos lab/UC Berkeley image)

At a national scientific meeting last week where biofuels - principally ethanol - were uniformly trashed as an environmental train wreck, one bright, carbon-free light gleamed in our energy future: the sun.


While the math bears closer scrutiny, the general consensus here seems to be a contradiction to what all the politicians keep talking about. "Green Fuel" is a myth. No matter how you slice it, the SUN is our number one source for clean free energy.

Now if we could just convince the corporations to cease and desist on their price gouging for the technology we would be OK.

Suddenly an Obama Socialist Policy seems good for this type of action....

of course a corporation would have to get a contract for the US....gouging there.

needs some R+D. Anyone have some amazing solar companies to invest in?

the USA is huge, of course u guys have enough land to produce completely green energy

The UK has 1/6th of the population living in the volume of only 1 state and yet the majority of our country by space is countryside, even we have enough space to produce green energy

hmm soo anyone looking at the whole worlds use of renewables, who is in the lead?

No they can't!!!!!. i live and own property in that orange square.

Build it in someone else's back yard.

The land in the Calif desert is not all waste land as many that live in other parts of the country think.

Most of the property that could be used for project like this are the little remaining desert public lands that the tree huggers have not turned into wilderness.

Most of the rest is privately owned and the tree hugger are trying to steal that and turn it into wilderness.

Someone really needs to have a talk with the tree hugger
on one hand they talk about saving the desert by turning it into wilderness areas and at the same time they talk about useing it for solar power.

That kind of schizoid thinking to me.
But many of us believed that treehugger were crazy all along

We need treehuggers because we need trees. Where are you going to get oxygen and clean air without trees. If you look at Brazil now they are cutting more and more trees and the weather is changing and not for the better either. Remember, we do not own land. We are just the costodians of it. We must take care of our planet or die. As for solar power, we can make, I am sure we already have it, better solar energy collectors so that we wouldn't have to take up so much land. There are so many inventions out there that can help us but it seems that some corporation is stopping it from being developed to its fullest. The corporations would lose money and as everyone knows money seems to rule at least for the forseeable future. Once that stops we can look forward to a better world. So lets go after these corporations that is stopping all this progress.

Next time they want to build a coal, oil, or nuclear plant they should take all that money and invest it in putting solar panels on people's roofs. They could rent the roof space from homeowners, and connect the panels into the grid instead of into the home in question.

Great idea, we get plenty of power when the sun is out, but on a cloudy day you get maybe 25% of your needs. Oh and I forgot, in the winter you get maybe 9 hours of sunlight. So at night where are we getting our power?

Is this big oil tipping its hand again? Consider the amount of energy, raw materials, and resources it requires to produce these solar farms, and how are you going to keep energy for night use? A few tons of lead batteries?

Oh and you have to sell your car and get an electric. That way we can consume more resources.

You have no doubt seen or heard that ethanol is imposable, and that is true if your only using corn. Some estimate it would require all of Africa's land to produce enough corn ethanol to replace the oil we use now.

But on a local basis, using cattails or other high starch plants, it makes sense.

Ethanol burns clean, and since it is made from plants, the CO2 is offset (not completely obviously). And it's portable. And you can convert your current gas loving tractors/trucks/cars to use it instead of buying a new one. I'm sure this has been on the site many times but after your read www.permaculture.com..., it's hard to deny the benefits of small-scale ethanol.

I don't know, but with dual core solar panel inventions and the more recent ones, not to mention that these collectors could be on skyscraper tall buildings, as could greenhouses for food production, this doesn't really make sense.

Another point, is, considering that they just found a way to turn C02 into large amounts of fuel, why are they talking about energy problems. All they have ever had is energy SOLTUTIONS and now even better SOLUTIONS yet, they bury heads and pretend they didn't see that. Why?
