==Notes== * Adjustable "Sun angle" ** This would require varying both the direction of the collimated light as well as the simulated path length of the light through our artificial "atmosphere" ** The former could be accomplished by rotating the mechanism mechanically ** To achieve the latter, if we are using a fluid to simulate scattering, we may be able to change the shape of the filter, pumping liquid in and out as necessary ** Alternatively, we may be able to create a 3D filter which we could rotate to change the length of the path taken through the substance, and/or use a clever arrangement of reflectors to pass the light through said the material several times * Rayleigh scattering ** Using alumina particles: https://pubmed.ncbi.nlm.nih.gov/24058661/ ** We may be able to use an optically transparent material other than water, such as an oil ** We could also use a solid material, such as glass, a polymer, silicone, etc. * Heat dissipation ** On the one hand, a large version of this is going to produce a lot of heat ** On the other hand, Noisebridge has been uncomfortably cold lately, so maybe we could harness the "waste" heat to help defrost our hackers' fingers ** Using liquid cooling to feed a heated floor seems just impractical enough to mention, but we could probably just blow air over the radiator and duct that air toward said hackers * Acknowledgements ** Thank you [[User: Murph]] for workshopping these ideas and for sharing much of the information above ** Thank you Noisebridge Illuminati for entertaining [and possibly bankrolling] these ideas ** Thank you dear excellent human for reading [and participating if you so choose]!
