Does Biochar Deliver Carbon-Negative Energy?

(May 19, 2010) Johannes Lehmann, Associate Professor of soil biogeochemistry at Cornell University, discusses the characteristics of naturally occurring terra preta including its agricultural and carbon sequestering benefits and then turns to considering the factors involved with implementation industrial biochar systems for large-scale carbon sequestration and energy provision.

In fact it is a very useful discovery. It can help much in agriculture

True Free energy devices exist,But Millions are spend in supressing that information,Get a REAL working magnet motor at LT-MAGNET-MOTORdotCOM ,Start the energy revolution!

I would like to Thank everyone who has taken an intrest in BIOCHAR as the only way to understand a thing is to take an intrest in a thing.

Biochar will help the enviroment and that is for sure. Mother nature knows best and once mankind catches on our planet can be restored swiftly.

So get interested anyone can do it and you don't need to be a edumacated scollar infact some of the most exciting and passionate people in biochar I have met don't believe in the edumacation system.

Take a cheap location, a desert not to far from a river (water and transportation), grow hemp there to make food oils, ethanol, wood gas and biochar in one process supplementing with solar thermal, recycle the heat and the chemicals.

No need for crop rotation or fertilizers. The hemp roots and biochar fertilize the soil making the land more valuable, the food oils is super valuable, the ethanol is pure profit.

This system has numerous synergies.
