Whenever someone tells me that glucose is the preferred fuel because we burn it first, I tell them that we burn alcohol before anything else. Using that logic, we should all be hocked up on liquor 24/7 . What makes real sense though, is that the body will metabolize the most toxic fuels first.
Some tips on electronics in cold: 1  Most electronic components are not damaged by ânormalâ cold temperatures. 2  Condensation can be a problem, if the temperature cycles between warm and cold with humidity.  Batteries lose capacity in cold (battery powered devices might not work in the cold)
Each diode (they are a semiconductor diode) can reach as much as 40-50 degrees difference in temperature if there is little actual heat being pumped. One 2 inch cell will easily make ice from the air but 2 gallons will practically never freeze even with perfect insulation in a reasonable amount of time.
