I have independently come up with a few inventions, but all of them have been pattented by other inventors before me. One example is dimming windows that have liquid crystal centres. During the day, a wire from a solar panel sends a charge to the window in order to keep it see-through. A dimming switch is used to control the amount of current and thus adjust the amount of opaqueness of the window. At night, an alternative electrical source is used if one wishes to have see-through windows again. This invention is particularly practical for large office blocks which don't allways need curtains, but it can also be applied to cars, etc. Furthermore, I have also invented some wave-energy generators, but unfortunately I found out that these are already in use in Sweden. And some other, less interesting inventions...
