Continuing the concept of saving planet Earth with gnarly, repeatable hacks, the fifth and final challenge of the 2022 Hackaday Prize is all about making the world better with smart and sustainable hardware. While the focus is still on saving the planet, this time, anything goes. Does your project not fit within the confines of a previous challenge? Here is your last chance to enter the 2022 Hackaday Prize: Start your entry today!
Go Wild!
We’ve already run contest rounds that focused on green power generation, recycling, hacking tech out of the landfills, and just finished up making our world more climate-resistant and connected. How else do you want to use your hacking powers to make the world a better place? Well, that’s up to you. This is the wildcard round, after all. If your project helps to keep this planet running for future generations, you can enter it here.
The Save the World Wildcard challenge starts right now and runs until October 16th. As with previous rounds, we’ll award one of ten $500 prizes to each finalist, and the best projects will have a chance at the overall 2022 Hackaday Prize. So get hacking!
i vote for using the treadmill turned generator. could get a good 18 hours out of each one, put them on constant rotation, give them lots of time to think.
Some sort of crusher / rotating knife assembly at the bottom with drain tank, and you’ve got my vote.
I think I’ll freeze distill the atmosphere on mass, fraction off the CO² and bind it chemically into a solid compound.
CO²
Why is it not used more in refrigeration, along with butane, propane etc.
Ah yes, it’s not a propitiatory gas for which you can a charge a lot of money.
Apparently it is. There are rumors that automotive use of CO2 as an AC refrigerant was outlawed, but I understand that there are legal industrial uses such as supermarket refrigeration. I think it should be 100% legal, we’re putting it in soda-pop for crying out loud!!
Grow trees or other plants, and then burn them off into charcoal, then bury the charcoal. That’s a way to turn CO2 into a solid and bind it into a solid compound. Charcoal lasts millenia, that’s why we have terra preta in the amazon.
We live in the West. In the best place and at the best time in the history of humanity for the development of an individual. All of this was made possible by oil. So the question is not how to make it a better place. The question is to find how to preserve this dream and share it with the rest of the world when the mines and the oil wells are depleted. We should focus on how to have a relatively decent life under these conditions. The challenge is there.
