This week at Walgreens solar garden lights were on sale for $1.50 each, so I bought a flat of them for $36. Considering what I pay monthly to keep the lights on in my home, this is a bargain because it assures me I'm never going to be sitting in the dark all night long even if the grid goes down. Not only do I have perpetual light, but I also have a perpetual supply of batteries now, because each light runs off a single rechargable AAA battery, which can be charged in the sunlight during the day and then used in various appliances, such as radios or regular flashlights, at night. I also found this idea online and I'm going to give it a try - making solar jars.
