I thought about using static charged material to get electricity. I am not a physicist so I cannot exactly explain how it works. When you walk on a carpet and you are wearing the right material you will be static charged. After being static charged you can touch something and you will get a small electric shock. I thought about using this electric shock to get electricity.
Your house has to have carpets in every room. You will get socks with the material which can be static charged. In your hand you have an adapter which can be used for loading a battery. Then you walk around for a while. The longer you walk the better. You can do whatever you want you just have to move. While walking you permanently give small electric shocks to the adapter. The battery in the adapter will be loaded and at the end you can use this battery for whatever you want.
I do not know whether this could work like this nor do I know how much electricity can be produced by using electric shocks but this would be my vision to get power for something I use every day.
