Save time AND the environment with this new gadget that encourages people to shut down their laptops more often. Finally, the product that the market has been clamoring for: the laptop remote-start key fob.

Background:

Some cars have a “remote start” feature to start a car before you actually get inside. This feature is typically used in regions with extremely cold  weather.

The issue:

Some people like to entirely turn off their laptops when traveling or over a weekend.

But then they have to wait a couple of minutes for their laptop to boot, log in, and start all their applications / open documents again.

Think of all the lost productivity!

Proposal:

Instead of losing precious time on Monday morning waiting for a shut-down-over-the-weekend laptop to boot, your laptop could have a special low-power “wake up” mode activated by a remote control. This would be exactly like a car remote-unlock key fob.

A comparison of laptops with and without this remote-start feature is shown in Figure 1.

Fig. 1: Top: this old-fashioned laptop doesn’t have a remote-start feature, so someone is going to have to wait several seconds for it to boot. Bottom: thanks to the remote control, the laptop on the bottom is ready to go by the time its owner walks up to it.

Conclusion:

The laptop remote could be a new differentiator between brands in an otherwise commoditized market. When every other laptop is the same, surely consumers will flock to buy the one with the “remote start” option!

PROS: Saves valuable employee time. Additionally, probably several watt-hours per year per laptop, since it encourages people to shut down their laptops. The amount of energy saved probably offsets up to a whole day of increased energy usage due to global population growth.

CONS: It might take longer to locate this remote control than to just turn on the laptop by walking over to it.

Save over TWO DOLLARS per year with an eco-friendly dental floss trick for the environmentally-conscious. Dental floss manufacturers hate it!

The issue:

Dental floss has a serious problem with unnecessary waste: each length of dental floss has a “dead zone” at the ends that is used to wrap around fingers.

This unused region is thrown away without ever having been actually used as dental floss (Figure 1).

Fig. 1: Only the middle part of a length of dental floss (highlighted in green) is actually used; the ends are wasted.

Proposal:

Instead of wrapping the dental floss around your fingers in order to hold it, it would be ideal if you could just grip the floss directly. This would avoid the wasted end regions, but, unfortunately, human hands are not optimized for this use case.

Fortunately, there is a tool that is perfect for this application: locking pliers (A.K.A. Vise-Grips™).

Instead of wrapping floss around your fingers, just hold the floss directly with two pairs of locking pliers, one in each hand, as shown in Figure 2.

Fig. 2: Note how much more of the floss can be actually used (usable region highlighted in green), as compared to the situation in Figure 1. The locking pliers remove the need for the wasted “end loops” of dental floss.

Conclusion:

In 2019, $6 will buy you 120 meters (4724 inches) of dental floss, which translates to 1/8th of a cent per inch. So if you save six inches of dental floss per day, that’s (600 cents / (4724 inches / 6)) = 0.76 cents per day of savings.

PROS: Saves 6+ inches of dental floss per day, or ¾¢ per day! Over the course of a year, this saves a grand total of $2.78 in 2019 dollars, which could buy you two small coffees at a fast-food establishment.

CONS: A person who uses these will probably inadvertently chip a tooth or knock one out completely with these pliers. Maybe they should be plastic instead of metal.
