Comments on: Better Than A Rainforest? Air Capture Climate Technology Gets A Closer Look http://blogs.reuters.com/environment/2009/10/05/better-than-a-rainforest-air-capture-climate-technology-gets-a-closer-look/ Global environmental challenges Wed, 16 Nov 2016 08:14:55 +0000 hourly 1 http://wordpress.org/?v=4.2.5 By: Samantha Davis http://blogs.reuters.com/environment/2009/10/05/better-than-a-rainforest-air-capture-climate-technology-gets-a-closer-look/comment-page-1/#comment-342473 Sat, 17 Oct 2009 18:13:53 +0000 http://blogs.reuters.com/environment/?p=14186#comment-342473 REDD stands for Reducing Emissions from Deforestation and forest Degradation, not “in Developing countries.” The author should have done a careful fact check before publishing the post. It made me think that this post is not credible because the author does not know much about the REDD scheme to begin with…

Biomass contains carbon, whose ultimate source is the atmosphere, and if this carbon was deep injected into the earth using carbon capture and storage technologies borrowed from “clean coal” technology, this would be carbon negative, and could potentially be massively carbon negative.So, yes, carbon negative technologies are the wave of the future, and if we want to have a future, we need to jump on this bandwagon ASAP. One good place to dispose of the CO2 would be deep injection into basalt deposits under the ocean floors, where CO2 could react with the magnesium, calcium, and iron in these basalt rocks to make stable carbonates, an idea known as mineral carbonation.One way for our society to become massively carbon negative would be for us to transform the coal fired power plants into advanced, enhanced efficiency power plants that burn biomass or biochar, and capture and deep inject their CO2. In this way, our worst problem – the coal fired power plants – could be turned into carbon negative power plants.Regarding transport of biomass, local conversion into biochar could make biomass as energy dense, storage stable, and transportable as coal.

The problem is that we are not the masters of the earth, as many religons would have us to believe.To put things simply as regards CO2 and consumption of the earths resources, inocculate an agar dish(earth) with bacteria (Humans), put it in the oven at the correct temperature (temp of the earth) and watch the bacteria begin to multiply, at the begining on the surface of the agar plate there are only small colonies of bacteria(Citys) then over time the colonies become larger and larger eating up the resources around them, until an end point where there is no more resources left and the bacteria population collapses, (human race). It may be crude using bacteria as an example, but humans operate at the same principles, the only thing is that certain species of bacteria will still be here,when we are gone!

Or problem is the belief that some magic bullet will come along which will allow us to continually use energy and resources at an ever increasing rate with little economic or environmental consequences.The most efficient form of lessening the effect of Greenhouse Gas emissions is Energy Conservation in North America, Europe, India and China, but we hardly ever hear this from the world’s leaders, even though it should always be at the top of the agenda on any discussion of Climate Change.Without a change in people’s view about their “right” to waste energy, the rest of our efforts are futile.

This is going to cost and it will not fit in the coal mine. Dreaming is easy reality is hard.

Most plants are less than 5% efficient. Sugar cane, one of the most efficient plants, has an efficiency rate of around 7%. Now you know.

In addition how much carbon dioxide is released in producing the air capture equipment.
