Ice age 2.0!
There's a million million tons of excess carbon dioxide in our atmosphere. 10^12. Current capacities for removing carbon are in the tens or hundreds of tons per year. So we're not there yet. My sense is the technologies become attractive for use on Mars, their atmosphere is 95% carbon dioxide.

Not to seem negative, with the great work being done by harvesting carbon from the air. But what happens when we have a CO2/green-house-gas deficit? Our lifestyles created cars, green-house producing food chain, pollution from consumable goods where the negative externality. But what happens when our lifestyle makes zero-emission cars, green-house free foods, and carbon offsetting consumer goods. What happens to the O2 harvesting companies? Do they go out of business, or do they become the enemy?On Oct 28, 2019, at 11:01 AM, Tito Jankowski <tito@titojankowski.com> wrote:Wow Algacraft looks cool!

I'm curious what solutions biology might offer. Figured some people on this list might be thinking about it already.Thoughts?Cheers,TitoQuoteHypergiant Industries wants to use algae boxes to solve the problem....The prototype bioreactor is 3' x 3' x 3', and holds 55 gallons of water and algae. "Algae wants CO2 and light," the company explains on its website. "The light can be from the sun, or in this case, artificial light. The algae and water are pumped through a series of tubes to maximize their exposure to light sources lining the inside of the Reactor."Inside the reactor, the algae absorbs the carbon dioxide and in the process creates a biomass, essentially dried algae. In the oceans, dried algae has a crucial role: It sinks to the bottom of the ocean and creates food for microorganisms. The company says the algae biomass can then be "harvested and processed to create fuel, oils, nutrient-rich high-protein food sources, fertilizers, plastics, cosmetics, and more."The Hypergiant team claims the device is 400 times more effective than trees at carbon sequestration."With the first generation Eos, we have precise control of every aspect of the algae's environment and life cycle," Ben Lamm, CEO and founder, tells Fast Company. "It's a photobioreactor, but it's also an experimentation platform. We'll be using this platform to better understand the environment that best suits biomass production under controlled circumstances, so that we can better understand how to design reactors for the variety of environmental conditions we're going to encounter in the wild."The company has a local vision for the biogenerators. Rather than (at least at first) a field of the algae boxes in an energy grid, Hypergiant envisions HVAC units, close to exhaust and industrial pipes, breathing in the carbon dioxide from a office building.According to the International Energy Agency, buildings and building construction account for 36 percent of global final energy consumption and nearly 40 percent of the world's total direct and indirect CO2 emissions.But a prototype is still just a prototype, and Libby says the company has no plans to start selling quite yet. The next step, in spring 2020, will be to make the design for the algae boxes open-source and see what the world will make of them.End Quote
