A work in progress. Some tongue in cheek, some serious.

Lysol Drones

When someone sneezes/coughs/otherwise displays cold and flu symptoms in an office environment or school environment drones outfitted with a mister containing Lysol triangulates on the area and sprays it down. The area is marked and a roving drone will periodically spray it down for the next 96 hours. While I honestly think that exposure is the best prevention for getting sick, this will be marketed to helicopter parents and other germaphobes.

Update: Due to the recent 6-day siege with a nest of yellow jackets in my yard, Raid should get in on this.

A dramatization on the origins of the Roopkund Skeleton Lake

Why were the Greeks there? There’s gotta be a good story in that. Looking at you Spielberg.

Door proximity gauges

Ever go to open the bathroom door at the office only to have someone fly out, presumably late to a meeting, and almost hit you in the face? This would have two lights on opposing sides of a door. When someone is approaching from the other side the light on that side starts flickering, giving a heads up to any unsuspecting bathroom-goer.

Probably also good for restaurants for kitchen doors.

A documentary on Dr. Benjamin Rush

Yeah I know Alexander Hamilton is the Founding Father du jour, but Rush’s story seems like it’s far more interesting.
