Guest essay by Eric Worrall
A while ago WUWT wrote about the inexplicable green fascination with technological monstrosities, such as artificial trees, to replace real trees. And of course we already know about the green love of wind turbines and solar farms, which cover vast acreages of the natural landscape with concrete, plastic and steel.
Now greens appear to have gone one better – toxic artificial trees which emit cyanide.
According to Phys.org;
Globally recognised for his work the emerging field of nanoporous materials, Prof Vinu’s research into carbon nitrides has found that they have just the right properties to support the capture and conversion of CO2 molecules.
“Their interesting properties—a semiconducting framework structure and ordered pores—make them exciting candidates for the capture and conversion of CO2 molecules into methanol which can then be used as a source of green energy with the help of sunlight and water,” Prof Vinu said.
“My goal is to develop this unique approach which has the potential to make a huge contribution to cleaning the environment and addressing one of our most significant environmental problems, the mitigation of atmospheric CO2.
“This fascinating material is not only helping in reducing CO2 levels by developing an efficient, low-cost photo electrochemical semiconductor device, but also offers a clean fuel source from the conversion of absorbed CO2 molecules.
Why do I think carbon nitride based trees could emit cyanide? The reason is cyanide is carbon nitride, with an additional hydrogen atom attached, chemical formula H-C-N. If you expose a carbon nitride nanoporous matrix to ultraviolet and water, its difficult to imagine how you could not produce a quantity of cyanide, as a byproduct of the photochemical deterioration of your carbon nitride matrix.
Perhaps Professor Vinu has a solution, for stabilising the nitride matrix, and keeping the cyanide emissions to an acceptable level. Personally I have my doubts – as China’s environmentally horrific rare Earth mining operation shows, greens often don’t seem to mind environmental damage, when the pollution which causes that damage is produced as a byproduct of doing something “green”.
