Default Cancel all Biofuels projects - they are a dead end and finially someone spoke up

Someone did the math - If you starved the entire UK of all its farmland, no food to the people, you would have the capability to basically keep up with the needs of Heathrow airport and nothing else.

Nice.

Yeah, first generation biofuel is bad. Second generation, not so.

Does this mean the third generation will be positively healthy.

Now that Terminal 5 is complete, will that not lead to even more air traffic ?

link me to the differences. Apparently this article was supposed to take the latest tech into account, so I'd be interested to see how much can be squeezed out of a field of crop.

The "new" biofuels should use only non-edible products from various sources, like some "fast growing" trees that have no other use, also some algae and other vegetal sources.
Not only that, but if you use pyrolyis for the conversion, producing biochar, you not only will get a "green petroleum" out of it but biochar...basically a charcoal which can be used to make soils more fertile and means the process is carbon negative and removes carbon from the air. This is what they think the Amazon Indians did, using slash and char rather than slash and burn to make fertile soils that still exist and may have supported large populations in the past.

Making a fuel out of something that people eat did not sound like a good long term solution. Now if we can make bio fuel out of waste or stuff people can't eat than maybe it could work.

Hey, I've known businesses that have been run on bullsh*t for years!

Yup, read my links....so we could grow corn and use the rest for biofuel and this biochar which can be used to make soil more fertile and store excess co2.

Default switch grass as a biofuel feedstock

I am hearing good things about switchgrass which is a fast growing weed.

The only down fall to this plant is that it may deplete the soils nutrients over time. But all plants will do that. Switch grass can be harvested more than one time per year so it's a fast growing plant. It will then require some fertilizers to replenish the soils it grows on. That will increase the amount of energy needed to grow this stuff for biofuel feed stock.

I think that we are making a big mistake by growing corn to use to fuel or vehicles. This takes food away from people and increases the price of a lot of food. Many products are made from corn. Corn syrup is used in a lot of our food products.

Instead of letting our vehicles eat or food I would much rather see the USA spend a lot more money on helping the fuel cell products get going in this country. I see that as an almost endless energy source.

We need to learn how nature captures the sunlight to manipulate carbon like the green plants have been doing for millions of years now.

We can use coal or nuclear in an emergency but I would not want to depend on nuclear energy if we can produce energy in other ways.

Fuel cells using hydrogen and the suns energy would be the ideal.

No one read what I wrote or posted. This method uses any waste non-food biomass and as a by-product removes CO2 from the atmosphere.
