Trees lock away carbon (A tree's mass comes from the air, not the soil) and produce a useful building material. If we could produce a way to make "bricks" from the atmosphere, that would be a game changer.
"To win the competition, teams must demonstrate a rigorous, validated scale model of their carbon removal solution, and further must demonstrate to a team of judges the ability of their solution to economically scale to gigaton levels. The objective of this XPRIZE is to inspire and help scale efficient solutions to collectively achieve the 10 gigaton per year carbon removal target by 2050, to help fight climate change and restore the Earth’s carbon balance.<p>Teams can submit entries across natural, engineer and hybrid solutions. Judges in the competition will evaluate the teams based upon four basic criteria:<p>- A working carbon removal prototype that can be rigorously validated and capable of removing at least 1 ton per day.<p>- The team’s ability to demonstrate to the judges that their solution can economically scale to the gigaton level.<p>- The main metric for this competition is fully considered cost per ton, inclusive of whatever considerations are necessary for environmental benefit, permanence, any value-added products; and<p>- The final criteria is the length of time that the removed carbon is locked up for. A minimum goal of 100 years is desired. "<p>Just providing the criteria for those interested. This is from the Xprize website.

How about some sort of internet blocker where you can just nix the users from your life who bring up whatever random negative crud they have read on Vox every discussion?<p>Flag on Jevons paradox, or Bitcoin, or random environmental issue they just assume is global warming related, or the thing they don't like so no one should have it.<p>It's a bit meta I guess, but it should work, get productive discussions going and get at least part of the population supporting real change.<p>Worst case it'd solve the biggest global warming detriment, annoying people.
PSA for everyone going "trees!!!111":<p>1- Trees take time, and are picky about location, not all planted trees survive<p>2- Trees don't grow on Mars :D (iirc he needs to capture Martian CO2 for his rockets, and any incidental improvement on the Sabatier might be useful for him)<p>3- Elon already gave like a million bucks to team trees, how long will it take for that money to absorb a relevant amount of CO2 compared to whatever this process this prize might entail?
If we actually want to prevent global warming, we will need a way to remove co2 already up there.<p>To be clear, I'm agreeing that this is an important and neglected area of climate research.
I want to be enthused, but Tesla getting invovled with one the stupidest wastes of energy on the planet Bitcoin on the same day makes me non-plussed/kind of miffed.
I don't see why these challenges are attempting to find a solution that captures greenhouse gases from the atmosphere. The concentration is so low, that to process large amounts of CO2, the amounts of energy required to blow the air through a system would be insane. Why can't we just plant more trees and focus on reducing greenhouse gas emissions (transportation and energy production).<p>its like trying to bail water out of the sinking ship using a cup instead of fixing a breach
Restoring forests and topsoil through economic incentives that change farming practices is what actually might make a difference here. But that's obviously not the techno-fix Musk is looking for. Sigh.
