@professor Yes, you are correct. Thanks for your explanation as it was a great read. As far as reliable power we can't do anything about a car vs a pole or acts of nature. But from the generators & transmission lines down to the distribution system we do maintenance daily to ensure the best possible service. Unforeseen circumstances are handled in a timely manner.
In the past I have installed micro-grids using high output generators in hurricane ridden areas. After work when we go back to our assigned accommodations the generators and water supply are turned on for 2 hours at night and 1 hour in the morning. That is because diesel fuel is sometimes very limited. During this time everyone tries to charge their electronics. I could use a PowerCore or PowerHouse for all day use to charge up my stuff and then some. I could always charge the Core or House when doing maintenance on the generators.
Also agreed that industry should be moving to USB powered devices. Solar is a great option but the storage is a problem when using a demand high load.
