How about having one of this crank in one every room for using it only for light?
custom straight pipes. go to any custom welding/fabricating/exhaust shop and tell them what you want. they will do it and it will be cheaper than if you bought a prefabbed kit
all straight pipe with cherry bomb glasspacks.
I'll do it but you do the cranking p.s I'm afraid of the dark crank faster
Cranks definitely have their use. They complain a lot and call attention to problems, serving an important community function. Crank callers ensure that every phone line gets used once in a while. But in my experience cranks generate much more heat than light.
