Solar Heater

Bill
Solar heater made from soda cans. A 1 inch hole is cut into the bottom of each can. Cans are glued together into rows (can top to can bottom). Cans are then painted flat black and mounted. Reflective coating or foil is placed behind cans. Enclosure is insulated except for glass facing. Air flow is from bottom to top. A slow moving fan (solar powered) can be mounted inside the air exit duct to augment the air flow. #soda_can_heater #Solar #solar_heater
