Light bulbs, what’s not to like about them? They were invented by Thomas Edison. I don’t know what we would do without them.
My thoughts on what we would do without them: My first thought is that we could just rely on natural light, it would be cool if we could replace the roof with colored glass.
Or we could just only stay outside until we need to go inside for whatever reason. The people that are in hospitals could just have there own separate room outside.
But at the same time natural light wouldn’t work because if it’s a cloudy or stormy day then there would be no light then and I’m sure that people wouldn’t want to spend the day in the dark.
Or we could just invent the LED light so we wouldn’t have to be forced to live in the dark on a cloudy day.
