I like your ideas; had a similar thought for Solar Air Conditioner. If you had higher fins and had 4 of these units facing in ; a fan and you have an Air cooler.

As a kid I remember dad driving us through Old Jindabyne, over the bridge and up to the new town site; Back then you could drive on the work roads. We used to drive the car into Tumut 1 power station, 1 km underground.
I got a Milwarkee, $505, no battery, it's $230; already have the charger for 240 & 12v, can use the battery on my other 18v stuff too. Cuts like a motherinlaws tongue, and get about 1/2 hr cutting. :Y:
I got one similar on e bay , and it has an alarm if it is disturbed. Has a combination lock though. Just run the cable through things and around the drawbar.
As long as you don't have a floating ,dream ,cloud like sleep; and then find you wake up and got a harp and not a mobile phone in your hands.
Get well soon, and I hope this works better for you.
Nice score Lesgold.
I had trouble with my pick falling out as bent down to check a signal; put some seat belt with a stud - rivet on one end and velcro on the other,on the pick holder and problem solved, never had it fall out again.
