It is the year of 2020. We are in the backyard of a suburban home in northern California. It is a nice summer day and we are having lunch with the neighbors. They are a quiet innovative family with an all solar-powered home. They brought over some potato salad made from the potatoes they grew in their backyard. We made some fruit salad from the bananas, apples, strawberries, grapes, and watermelon that we grew in our backyard. Although it is blazing hot we have a solar powered fan blowing on our outdoor picnic area. We called it the fruit/potato picnic. We have them annually; every forth of July.
