Sometimes, a college lecture or work presentation goes far over the allotted time (Figure 1).
Frequently, the presenter doesn’t even realize that they are over time.
One simple way to prevent a presentation from going over time would be to just have the power outlets turn off at exactly the designated end-of-presentation time.
However, this hard stop could be annoying: what we really want is something that will make the presenter inherently want to wrap up their talk.
The solution is simple: just have an array of heat lamps pointed directly at the presentation podium.
When the time limit has expired, the heat lamps turn on, one at a time. At first, the podium will be just a little warm, but it will quickly become scorching and unbearable. Thus, the presenter is encouraged to conclude their talk in a timely fashion.
An earlier shark-related proposal turned out to be too expensive, as it required creating a new auditorium with a raised platform above a shark tank. So this is an almost-as-effective solution for the university or business on a tight budget.
This heat lamp idea could be used in conjunction with an earlier software-only plan to “burn away” slides as they are shown. This “burning” idea would synergize well with the heat lamps, too!
PROS: Does not have the same recurring maintenance costs of the shark version of this idea in the link above.
CONS: May cause a circuit breaker to trip if the building is not wired for 6000+ watts on a single circuit.
