The first solar battery was introduced this day in 1954, paving the way for many household solar products. What's not to love? No cords, no batteries, and no electric bills! Home solar products are good and they're getting better every day. Solar yard and walkway outdoor lights are steadily improving, with better output for longer times from fewer hours of sunlight...all at lower prices! Other innovations include solar water heating -- for indoor use, for swimming pools, and even for birdbaths (to keep them from freezing.) There are solar panels that produce electricity for every use imaginable, from household power to charging cell phones, laptops and music devices like solar radios and mini-disk players. They even power lighting for boats, RV's and sheds. And for cars, there's a hook-on window auto vent that draws out hot air while the car is sitting in the sun. Got solar yet? If not, check it out!
