Finding news way to get even dumber…

This new mask developed by experts at New York’s Cornell University is disposable and transparent. They are designed to suck up any Covid-related fluids and droplets that are coughed up. They are connected to a pump that creates a reverse flow of air around the wearer’s head.

Any potentially infected droplets will be sucked up and contained in the airflow passing through the mouth aperture so that the germs will not leave the helmet.

It is also proposed that otolaryngologists (ear, nose, and throat doctors) would be interested in this new helmet.

Hooked up to a computer-based fluid dynamics simulation, the designers discovered the helmet could contain 99.6% of droplets when the wearer coughs within a tenth of a second.

To put this into context, if we use the same air pump to create a negative pressure isolation room, it will take about 45 minutes to remove 99% of the airborne contaminants from the room.

Our next step is to refine the helmet design to have higher efficiency and broader application. After that, we plan to build prototypes of the helmet and perform experiments to verify our simulation predictions.

[28] And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; [29] Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, [30] Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, [31] Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: [32] Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
