Carbon Negative Biofuels?!


A potential new fuel has been developed by researchers from the University of Georgia using wood chips. Small bits of wood are heated in an oxygen-free environment to produce charcoal and www.y-e-n.net a gas. The gas can then be condensed into a liquid bio-oil which can be processed into a fuel which can be blended like bio-diesel. The charcoal is being investigated for use as a fertilizer. Since much of the carbon from the wood or plant matter becomes charcoal, rather than part of the fuel, if the charcoal is put back into the http://www.massing.de/ordering-cialis ground as fertilizer, then this fuel is how to buy viagra in canada net carbon negative.
You're taking carbon out of the atmosphere when you grow a plant, and if you don't use all of that carbon and return some of only for you lowest price for viagra it to the best site on line pharmacy the soil in an inert form, you're actually decreasing the amount of carbon dioxide in the atmosphere," Adams explained. "We're optimistic because in most types of soil, carbon char has very beneficial effects on the ecology of the soil, its productivity and its ability to maintain fertility.
One potential drawback to this is viagra england that only 15-17 percent of the dry weight of wood is turned into this fuel. The charcoal produced accounts for another 33 percent of the weight of wood. But that still leaves roughly 50 percent of the byproducts of this process unaccounted for. We aren't told if that material becomes useful materials or waste?

"Slash & Char" agriculture
written by Matt James, June 19, 2007
Bringing carbon back to the earth as charcoal is a time tested technique: it has been used for centuries in the Amazon basin. Indigenous people there will clear a field for planting crops by charring the brush and returning it to the soil... this differs from "slash and burn" in that it's not about reducing everything to ash, which poisons the soil a little bit, but smoldering everything which only releases about 50% of the carbon into the air - and results in deeply fertile soil.

How can this possibly be 'new'?
written by Jay, June 19, 2007
Producing gas out of wood has been done for decades, heck, almost a century. It is proven technology. http://en.wikipedia.org/wiki/Wood_gas
Condensing the online pharmacy no prescription cialis gas to a liquid fuel is also far from new. It is called BTL (Biomass To Liquid).

I don't want to wow look it generic cialis sale stop your enthusiasm, but please, get a grip... ;-)

But the charcoal in the ground is going to decompose eventually releasing the carbon into the atmosphere.

Compost

Getting the right balance of Carbon and Nitrogen is a big part of the art and science of tramadol online without prescripton composting (at home anyway). You could, in theory, sell it as an additive for people composting large quantities of fresh cut grass (since grass gives off a LOT of Nitrogen). In this case, the carbon would go back to the soil instead of the atmosphere.

Just a thought...how much energy, er, CO2, is produced in the production of this in the first place? In the process of heating the wood to 700 deg C...

50% unaccounted for

I'm guessing water might be a big part of that missing 50%?

Yes, the tree is fertilizer. If the tree eventually falls, rather than being harvested, it is fertilizer, and if it is in the char form discussed, it is fertilizer. Is this building soil faster than wildlands? Unless we can say yes to this, it is not carbon-negative.

There are people doing research on how we can build soil faster. More soil= more carbon in the soil rather than in the air. It also means more productive soils. This is an important area I seldom see discussed (except perhaps in permaculture, which tends to get dismissed as too hippie).

If plants take carbon out of the atmosphere, then why don't we just plant more plants to reduce global warming. it seems to me it is easier to levitra online in usa plant more plants than to tell companies and cheap tramadol 180 for $75 countries to stop producing and growing.

how about spending those carbon credits of Al Gore on producing more efficient plants than will pull more carbon out of the atmosphere?

How about sticking plants on the tailpipes of every car to absorb some of that CO2?

the government could pass a law to require at least 2 plants on the back bumber, and you can add more for tax credits - $200 for each aditional plant. Then, I can hire an illegal alien to trim my car plants as well as my lawn.

Biofuels using carbon sequestration
written by Rodney Hill, July 03, 2008
Other sources of biofuels using cellulosic ethanol methods can also use flash carbonization both as energy to produce biofuels as well as reducing CO2 - it would be possible using crop waste, switchgrass, etc.
