Free Hot Water
"Store" daytime sunlight for night-time heat by placing bottles of water (or buckets with tight-fitting lids) in direct sunlight coming through your windows. This warms the water. When the sun stops shining on the bottles or buckets, their stored heat will be slowly released. Paint the bottles or buckets black to store more heat. This is free hot water for bathing or washing dishes!
