Placebos work all too often. The power of the mind to believe in healing often starts the process. Doctors know well the power of the mind in recovery. Tesla shields work for those who believe they do. So do the millions of people who cross their fingers get some manner of protection from evil spirits.

Tesla is an iconic figure in the "alternative" universe. By using name association and the liberals favorite pride color - purple - they tap the small percentage of subconscious minds of their target audience: millions of left-leaning "alternative" fans who are willing to suspend disbelief.

And yeah, in some part of the infinite multiverse on one of an infinite sea of parallel Earths, the Tesla shields are real...and they do all that they claim...using the most advanced technology you or I have ever seen...
