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.

Economists pulling their hair out with the naivety of the assessment. Carbon charges will be passed on to the customer, and thereby their financial supplier, their employer, for instance.
Just give up the Avarice, the stuff, the debt,, the consuming. Just do that. Don't be disingenuous. The logical conclusion of consumption is planetary death.

If you want to reduce CO2 (why would you it's a net benefit ), we need to restore the rain forest,all the gardens in the world are a collective CO2 sink,there are plenty of dwarf trees even large shrubs for small gardens would make a difference if it's done collectively.I do not buy in to this new religion, lot of people depend on the funding for this! What percentage of the atmosphere is CO2? Look it up!

Switch on plant based food and you’ll have 18% of CO2 down

If you really want to reduce CO2 emissions (which is not the only greenhouse gas BTW - I don't believe in CO2 mediated climate change), vegan is the way to go. The animal farming industry produces more C02 than cars, ships and planes combined. I a vegan because of health reasons, and I drive a Prius because I like how it handles and saves me money, not because of climate.

At 150 ppm and below, plants die, starved. Earth is at 400 ppm right now. Lush forests and hyper-abundant fauna covered the entire Earth when CO2 was at 2000 ppm. It is ridiculous to think that we need to remove CO2 from the air. The Earth does not have a carbon problem. It is a political issue tied to depopulation and totalitarianism.

When the Greenland and Antarctic ice sheet melts enough and awakens then releases all the trapped viral and bacterial spores, the global pandemic will fix our CO2 emissions really really fast. Earth wins again and does not have to wait for the next meteorite to hit us. So let’s just enjoy ourselves till then and stop worrying about all the stress that these scientists are throwing at our collective consciousness. Tesla, you are too late with your inefficient batteries.

Spend a trillion dollars on something that takes up a billion acres and only captures 5% of USA carbon emissions....Never going to happen. Call us back when you can subtract 120% of US emissions for $1 billion and takes up a city block. The carbon suckers wouldn't make a dent in the average yearly emission increase. A waste of time.....Next.

Just plat bamboo and hemp in the desert.

We need to work with nature!

Is this just another word for a filter?

I just don't understand what problem do people have with her solution. It's good that technology has finally found a solution to climate crisis.

First remove CO2 from your body.
Nolan Alderfox
Naaa, all sounds dumb....compared to bio solutions.

We need more Co2 in the atmosphere 400ppm is still not enough for most plantlife too grow properly! It’s time to get rid of the religious ideology that co2 is the main driver in our climate! It’s absolute madness to believe that co2 alone affects climate. Water vapor, clouds, methane, the enormous ball of intense nuclear madness we call our sun, the tilt of the earth, jet stream winds, all of those things have far more significant impact on our weather than co2 could even dream of having!

you cant solve the problem with the same mentality that created it   -= tech   we need nature on our side not

CO2 is a mobile form of carbon that is used to create the building blocks of life. In the Cretaceous Era CO2 was > 1000 ppm, perhaps as high as 1700 ppm. There was no ice at the poles and tropical plants grew at the latitude of what is now New York.

Oh dear, we need MORE regulation and subsidies, and MORE taxes. PISS OFF YOU HACK!!! Dried up old hippie...

Shoot Al Gore. He spews more hot air than any other entity on the planet...

Allowing fewer people like this woman to breed. That would be a good way to start...

Why you should make useless things A new way to remove CO2 from the atmosphere | Jennifer 6 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."
