I want to get a solar powered cooler, with a spigot/tap on from which to dispense the iced coffee, attached to a bicycle trailer. I am still considering the mechanics & daily practices of the idea, so for now i want to assume the licensing&permitting&health ordinances can be figured out. And i want to assume i can find a good supply of organic, fair trade beans. My concern now is can the logistics & economics work out--or more specifically, what equipment would be needed & how much would it cost. For example, there is a $700 solar-powered cooler that runs on a 45w or 75w solar panel. That cooler weighs 75 lbs, and holds 50 liters interior capacity, and from what i have found that kind of solar panel costs one or two hundred dollars and weighs 15 lbs.
My major logistical&economical questions that remain are: Can i find a commercial kitchen from which to rent space? How can I assemble a good set of cold-press brewing equipment while avoiding the use of plastics as much as practicable? What about a freezer, as opposed to a cooler?
for solar-powered purposes, a freezer requires 3.5 times as much power so it would get really heavy. but could i store a big ice chest in a walk-in freezer overnight, at the rented kitchen space, a.k.a. commissary, then haul it out on the bicycle along with the solar-powered cooler, in the morning? this one is expensive, but i think it weighs only 30 lbs. and maybe it has good insulation enough to get the ice through the afternoon: http://delfield.com/?xhtml=xhtml/del/us/en/general/product.html&productdata=xhtml/del/us/en/product/240.html&xsl=productdata.xsl&category=0003
The fact that this ice chest wouldn't have any refrigerant or cooling power kind of defeats the purpose of the solar-powered cooler, to an extent, or at least makes it more gimmicky........
so thats one of my dilemmas at the present moment.
thanks for any thoughts!
