Well, many of you will have seen the building of this machine already in the livestreams...Here's the result! For now this is an early release for Patrons and it should go live to everyone around 11am EST tomorrow!

Thanks so much everyone for your support of these projects! We definitely have a lot of new things to explore in the future.

DIY Machine Turns Bioplastics Into Cooling Fabric

DeleteMe international Plans: https://international.joindeleteme.com In this video we build a machine to make fabric from PLA that has been specially modified for high reflectivity. Because of PLA's strong emissivity in the infrared sky cooling window it is potentially a very good option for radiative sky cooling.

Agree with Cursedvoid, seeing the mistakes makes it so worth while, maybe we see something in the mistake that's a possibility for improvement, maybe we just learn you're human too. Suggestion for the PLA fabric, rather than relying on a plastic bottle with imprecisely shaped holes, perhaps you could try a metal cylinder and tap in holes for 3D printer nozles or inserts that you could use very small drill bits to fine-tune the fiber size. With more holes you could also make the fabric faster. I posted on Youtube a suggestion to see what happens if you suck air through your fibers, just curious what that might do. Other things to try : Have you tried ironing the fabric on low heat settings to compress it into a more solid mesh? How about slightly misting it with your solvent after it's done to get some air-gaps out of it, might get less insulation. Place it at a 90 deg angle to the sun with 2 mirrors to see if you can get both sides to cool? Spin it onto a copper mesh instead of screen and then leave it on the mesh to use the copper as a heat spreader. Can't wait to see more videos!

Well, I guess I should point out that Ben has been spelling my name wrong this whole time lol. I don't mind, but I'm surprised he isn't just copy/pasting our names into the description. thats gotta be a PITA to type out each time
