Is a university lecture or job talk going on FAR longer than it is supposed to? Emphasize punctuality with this new incredible heat-lamp-based presentation setup!

The issue:

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.

Fig. 2: The heat lamps above the presenter will gradually turn on when the presentation hits its time limit.


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.
