Well, from time to time every properly operating brain produces some ideas. Not related to your current job or even life. Some of them looks neat. Some of the last could have a real world application. And often it's not so easy to throw them away in a favor to daily vital doings. This looks like a feel of a young boy, who walked around, occasionally poke up a pebble and encountered a big window. The shining glass surface and the stone in his hand are becoming tied by some vibrant link that is asking spitefully: "throw it to the window, break it!" It is not so good.
The best way to get rid of a thought is to write it. Sure not every came idea. But one that seems implementable, useful and interesting. There will be no looks for analogs, though I'll thank if someone point me to them. No efficiency analysis, market demand research or ROI calculations. But I'll try to present these ideas as useful for people and (maybe) for designers and industry. Let someone other to get a soldering iron and to make the thing solid.
