Our planet has a carbon problem -- if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do ... but at a vast scale. This detailed talk reviews both the promise and the pitfalls.

withoutCO2 all plants die. the earth needs moreCO2.
Ton Hoffmann
This is hilarious. First create a non-existent problem and then come up with a fake solution. Of course you have to pay a lot for that, but what difference does it make. Let's all be on our knees for this Messiah who is coming to save the world. People are creative when they hitch a ride on the CO2 train. Here, in the Netherlands, there are already psychologists who help with GW stress. Can this lady also tell us who determines what the good CO2 value should be and for whom?
?:?
Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

what on a vast scale like the deforestation we've done (mostly for grazing livestock and growing feed for them)?

You could also stop deforestation Amazon Rainforest Deforestation Hits Highest Rate in 10 Years. About 7,900 square kilometers (3,050 square miles) of forest was cleared in the Brazilian Amazonbetween August 2017 and July 2018, the worst annual deforestation rate in a decade, according to government data

Your sums are wrong. You get C02 three times higher than it is. Get it right.
Also C02 is used in hospitals.Did you know that ? Ask a keyhole surgeon. No C02, no operation. C02 is pumped into greenhouses to grow your food too. It is the basis of life. 30,00 scientists know that you have the sums wrong, for goodness sake stop this rubbish.
We need it in the air. Do you want the trees to die. ?

Over 100,000 giant oil burners aircraft in the atmosphere 24/7 each one is burning 36 thousand gallons of paraffin every ten hours they are heating up the atmosphere and melting the sulphur dioxide and turning it into sulphuric acid rain, that is a lot of co2. no wonder skin cancer is on the rise, when you fly you are flying in a sea of sulphuric acid,causing aircraft engines to suffer from metal fatigue, corrosion, also cracks appearing in the body structure,the air in the plane is also very toxic, pilots and cabin crew have one of the highest rates of cancer out of all occupations, this is only part of the truth of the dangers of flying, when you are up in the atmosphere there is only one way down, paraffin jet fuel is a very volatile fuel they add nanoparticles of aluminum to the fuel to make it more explosive that is why aircraft explode and burst into flames on impacted. as an intelligent person i would never ever step foot on an aircraft i have seen the workmanship, the practical skills leave a lot to be desired. good luck,you will need it. google all about sarin nerve gas, the two main ingredients are sulphuric acid and aluminum fluoride. The American government and the UK government put aluminum fluoride the most deadly toxic industrial waste in your drinking water, you do not have to be a village idiot to work it out, it causes the human body to swell up, the Germans have banned it in their own country because it causes cancer, in Russia they pump the fluoride waste into the oceans causing the Beluga whales to die of cancer, do the science the truth is out there.

If you have a greenhouse to grow plants then you need a paraffin heater, they call it kerosene in America, in order to create co2 to make the plants grow, it also creates water.this why our towns a cities are getting flooded from aircraft pollution.they are giant rainmakers.methane gas is pumping out of the oceans floor, the human body creates co2 and methane gas, woman with saggy bottoms have them pumped up with carbon dioxide and botulinum the most deadly toxin on the planet to get rid of the wrinkles.they call it botox, you could not make it up. I am an old pensioner for sixty five years i have specialized in engineering and i cannot believe the way corrupt governments have brainwashed people with this money making scam.
alfred william
sulfuric acid from paraffin is killing us methane gas in the atmosphere is naturally occurring. rocket fuel and rockets burnt the hole in the ozone layer, one country cuts down half a million tons of trees a day to make cellulose, carbon capture is the most disgusting money making scam of all time.aircraft are giant co2 makers, they are giant sulphuric acid makers.heathrow airport in the UK consumes 29 million litres of paraffin a day aircraft create eight hundred billion tons plus of co2 water every week.
Honest Opinions
i don't trust their calculation of CO2 capture by forest..............secondly these factories give out oxygen?........surely not..........there is no comparison to what forest can do ...........
Honest Opinions
is she even aware how stupid the idea is?.............spend energy(burning fossil fuels!!) to capture CO2 and convert to fuel again.........first to to chimneys of all factories and capture CO2.....or make rules for every industry to do so......................encourage rapid transition to renewables................this is just a stop-gap solution promoted by wealth oil companies.
Peter Quinn
This woman is deranged.
The planet desperately needs more CO2.......... Do not listen to this ridiculous rhetoric. THINK for ourselves.
Michael Holmes
Why do you want to remove CO2 from the air? It is plant food and is at historically low levels. 1000ppm would be good, not bad, for plant life and by extension all life on Earth. The Climate Mafia have completely lost the plot.
truthbetold
we need more CO2 in our atmosphere, as it stimulates the growth of plant life, thus providing us with oxygen, food, and a literally greener planet

Why you should make useless things A new way to remove CO2 from the atmosphere | Jennifer 10 months ago   11:58

In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions -- designed to chop vegetables, cut hair, apply lipstick and more -- rarely (if ever) succeed, and that's the point. "The true beauty of making useless things [is] this acknowledgment that you don't always know what the best answer is," Giertz says. "It turns off that voice in your head that tells you that you know exactly how the world works. Maybe a toothbrush helmet isn't the answer, but at least you're asking the question."
