Electronic Refrigerator Inventory System
There should be an interactive digital display on your fridge door that you can use to see what’s in your fridge and how long it’s been there and when it expires. You could scan all the items as you put them into the fridge, and the device would already be programmed with information about, say, how long strawberries stay fresh. You could also manually enter expiration dates, like on your milk. The device would remember everything you put in, so when you first get it you might have a lot of data entry to do, but after that it would easily recognize what you’re buying. Then when you are wondering what you can have for dinner, all you have to do is look at your display and see that there’s leftover Thai from two nights ago and enough vegetables to make a salad. When you’re getting ready to go to the grocery store, you could print out–or upload to your phone–a list of what you need, based on what you usually need and is missing from or low in the fridge. For bonus points, the device could interact with a cooking app and suggest recipes based on the ingredients you have on hand. Or tell you that you have five ingredients you need for tacos, except the meat, so you should pick some up. Cleaning the fridge would be easy because you’d know exactly how long things had been in there even before the mold starts to grow! There is so much potential here.
NPR (or other news outlet) Warning Lights
Sometimes when you’re in the car with your kids and you turn on NPR and the first words you hear are “mass shootings” or “bodies of children” or “murder” and you have to switch the station very, very fast. Or even if your kids aren’t in the car but it’s 7:30 in the morning and you can’t stomach a report about terrorist attacks, children being sold into slavery, or anyone being shot, and you have to put on the soundtrack to If/Then, which can be kind of wrenching as well but at least you know what’s coming and it’s fictional. Anyway, there should be a little warning light indicator on your radio so you can turn it on with no volume and if there’s a horrifying story including any of the above words or others I could list but won’t because they will make me depressed, a red light would illuminate. If the story may be mildly disturbing but not heart-wrenching, such as unemployment numbers, Congressional ineptitude, or negligent landlords, the light is yellow. And, if you’re really lucky, the light will be green when they’re interviewing singers, athletes, or writers; sharing the triumphant story of someone’s success; or reporting on a breakthrough in medical technology. Not to say that you can never listen to bad news, but sometimes it’s just too much. This would save millions of listeners from potential anguish as they drive.
If you can invent these things, let me know. I’d be happy to brainstorm with you and get in on the ground floor.
