This video depicts a man (Mr. Michalak) that claims to have had an encounter with a device of unknown origin. It looked like a transparent fusion chamber (is that possible?). He was also hurt from expelled gases and the chamber’s extreme brightness. Smells included in the report were described as sulfuric and “metallic”.
My guess is a fusion device that uses a mix of gases including sulfur or some other sulfuric smelling gas. Lasers were also seen inside but I am not sure of its significance. The hull was interestingly thick and reminds me of the x-ray to electric conversion method. There are too many coincidences here.
