+==== Solar Air Heating ====
+(add project links for completed things - Jack)
+==== Concentrated Solar Power (CSP) ====
+CSP is a general catch-all term for [[http://www.builditsolar.com/Projects/Concentrating/concentrating.htm|using mirrors/lenses to concentrate a large area of solar radiation into a smaller area which receives said photonic energies]].  The primary benefit is increased temperature and the ability "to, like, instantly start things on fire, which is awesome".  This does also result in an increase in DANGER! due to the high temperatures.
+Fresnel lenses, which can be found in old rear-projection TVs are one way to do this.
+Another is the [[http://www.hacknmod.com/hack/diy-solar-death-ray-using-a-satellite-dish/|parabolic dish]] and the [[http://kmr.nada.kth.se/wiki/Amb/THOTDCPF | double cylindrical point-focus variant]] (which I'd like to try building -Jack).
+One of our members has also experimented with using a metallized film (mylar/space blankets) and a vacuum to create a variable focal length parabola-ish concentrator (which I'd also like to try building - Jack):
+"I don't know if this is an appropriate place, but several years ago I looked into making solar concentrators by stretching a metalized plastic film (specifically a "space blanket") over a circular frame and then pulling a partial vacuum behind it.  I made a test piece with a short section of 12" PVC pipe which set fire to a piece of wood in a few seconds.  This technique has the advantage of having a variable focal length by simply adjusting the vacuum behind the film.  It would be easy to scale it up to much larger diameters.  The curve formed is very close to a parabola, so close that I considered the possibility of using it to make a very large, light weight, short focal length telescope mirror with huge light gathering power." - The Digital Dentist
+==== Makerspace AE Projects ====
+=== Rooftop ===
+People: Bob Dionne, Ron Bean
+Solar air - there are air access portals...somewhere.  Ron probably knows where they are.  Probably locations are rooftop, possibly south facing wall.  Ron's pretty busy and not sure if he's going to get around to it this year.  Someone needs to go up there with Tom to make sure they don't break the roof and figure out how to mount and plumb anything we put up there.
+Wind turbines?  Bob's your uncle.
