Home delivery of food directly to a refrigerator is apparently a thing now. But what if there was ALSO a socially-responsible service to get rid of almost-spoiled food (while it’s still good)?

Background:

As civilization reaches an apex of decadence not seen since the days of Caligula, new and exotic labor-saving schemes have arisen.

Specifically, you may soon be able to order food directly to your refrigerator, thus saving you from having to be present for delivery. Deluxe!

The issue:

While the process of delivering food directly to a home has been substantially streamlined, there is not yet a great way of getting rid of unwanted (but still good) food on a small scale [1].

([1] If you have 5000 apples that you don’t want, you can give them to a food bank. If you have five apples, the logistics involved in transporting those apples means that they will probably end up going into the compost instead.)

Proposal:

The solution is to apply the same technique used in the in-home-delivery service, but in reverse.

In the “normal delivery” situation, a delivery person gains access to your house temporarily in order to bring in a package (e.g. “Amazon Key”).

But in the proposed “reverse delivery” situation, you temporarily give access to your house to someone who is in the neighborhood and really would love to eat a free food item that is about to expire.

It would probably be too labor-intensive to require a human to constantly monitor their kitchen for almost-spoiled items, which is why a computer-vision-aided system (Figure 1) is also proposed.

Fig. 1: This electric eye is constantly scanning for fruit spoilage in the fruit bowl on your kitchen counter. It should be able to give a readout of the approximate number of days remaining before each piece of fruit is no longer edible.

Once a nearly-spoiled piece of food is located, the system would automatically unlock your front door by communicating with a WiFi-enabled “smart lock” (Figure 2) and notify passers-by that there is free food for the taking.

Fig. 2: The presence of nearly-spoiled food causes the system to unlock the front door and to send out a proximity-based alert to nearby individuals who may want this free slightly-over-ripe banana. The notification could be done though a phone app or by proximity-based SMS alerts.

PROS: Helps reduce food waste and provides yet another motivation for installing home automation.

CONS: None! Brings the “sharing economy” to your kitchen!

Trash Can with an alarm that screams if you jenga more trash into it

TITLE: Never be annoyed when emptying an over-full trash can again, with this new “screaming trash can” technology!

The Issue:

In shared-living or office situations, there is a strong incentive to wait for someone else to empty a full garbage can: the person who discards the last piece of trash has only contributed a tiny fraction of the total can’s volume, but has to expend the trash-removal effort for the entire can.

Thus, people tend to creatively stack trash as high as possible (Figure 1), forming a “Jenga“-like tower of precariously-balanced trash.

Fig. 1: People will often stack trash in unstable towers, as shown here, even if the stacked trash prevents the lid from closing.

Even worse, once trash is piled up in a tower, it can be difficult to fit it all into the trash bag (which makes it even less likely that someone will want to take it out).

Proposal:

The solution is simple: install a grid of “electric eyes” (the laser grids from every heist movie) that would monitor the top level of the trash can (Figure 2).

If the electric-eye beam is blocked for more than a few seconds, the trash can would know that the trash can needed to be emptied, and can take action accordingly.

Fig. 2: The grid of sensor beams (labeled “electric eyes”) will, if blocked for more than a few seconds, trigger the “siren of shame” (bottom left). Instead of allowing the culprit to slink away in anonymity, the siren would wail until the trash-abandoner returned to take out the trash.

Gamification:

One could “gamify” the process (and help promote a dystopian 1984-esque future) with a trash can that would 1) have a camera to identify each user and 2) a weight sensor to keep track of the total amount of trash generated and emptied by that person. Perhaps stat tracking would encourage trash-can-emptying. Whether or not it actually helps, the manufacturer of such a trash can could always sell the face recognition data to advertisers and each country’s secret police, so it’s a win-win situation.

PROS: This would be a popular product for many homes and offices.

CONS: Creative individuals might be able to place trash in creative ways such that it does not obstruct the beams, but is still precariously stacked.

 

Chalk up another astounding win for the Internet of Things: another major plague on humanity is BANISHED thanks to a wireless chip in your blender.

Background:

People occasionally forget to lock the door before leaving the house, or leave a stove on by accident, or any number of other things.

“Internet of Things” aficionados often suggest that you could, say, turn on and off your stove from your phone, but now someone on the Internet thousands of miles away can also turn on your stove at a random time.

Proposal:

If your appliances could report their status wirelessly to a receiver on your door, then you could check your home’s status as you leave.

Anything that is amiss will glow in an obvious fashion that calls for more investigation (see mockup in Figure 1).

Fig 1: Since this panel is on your main exit door, it’s nearly impossible to accidentally leave something on / forget to lock the door / leave the microwave popping popcorn for 90 minutes instead of 90 seconds / etc.

Conclusion:

Since this is a one-way channel of communication, you don’t have to worry about hackers turning on your microwave. (Additionally, high security is not crucial here; exposing the information “your microwave is on” to a hacker 8000 miles away is probably not a realistic concern unless you’re making a contrived scenario for a made-for-TV movie.)

PROS: As with all Internet-of-Things things, it solves a problem that actually does (juuuuust barely, anyway) exist, and (more importantly) provides a great hobby for engineers.

CONS: In five years, when your smart home hub supplier is out of business, none of your new appliances will work with your system. And when you buy a new dryer, you’ll have to research it for 80 hours to to see if it’s compatible with your version of the Smart Home hub, and then you’ll to have to dig around on the internet for a firmware update named SmartHouse_v_2.7_North_America_41.80.24b.dat.zip. Which will then turn out to be malware that turns your hub into a Dogecoin miner.
