Don’t mean to toot my own horn, but in the 60s I worked in the scrap/recycling business. In the 70s my gallery sold all handcrafted metalwork, some pieces created from recycled scrap metal, old square nails etc. In the mid-80s The LasVegasBuffetclub’s fleet RV sported a 12″ x 12″ solar panel that powered a small TV at night. It was wired to a motorcycle battery. Las Vegas was the perfect place for solar – Mega Sunshine.
