Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.

Reddy Kilowatt made his first published appearance on March 14, 1926, in an advertisement in The Birmingham News for the Alabama Power Company (APC). The character was the brainchild of the company's 40-year-old commercial manager, Ashton B. Collins Sr. [3]
When linked in series, the cells had sufficient power to electroplate a small token and to deliver current to acupuncture type needles for therapeutic purposes, but not enough to deliver an electric shock to MythBusters co-host Adam Savage who was instead pranked by co-hosts who hooked him up to a 10,000 volt cattle fence shock generator.

Image credits: Electrical-Aspect-13 We were curious to know how photography has evolved throughout history. "The norms of photographic portraiture stem from Victorian times when photography began.
Coronas can generate audible and radio-frequency noise, particularly near electric power transmission lines. Therefore, power transmission equipment is designed to minimize the formation of corona discharge. Corona discharge is generally undesirable in: Electric power transmission, where it causes: Power loss; Audible noise; Electromagnetic ...
A Lichtenberg figure (German: Lichtenberg-Figur), or Lichtenberg dust figure, is a branching electric discharge that sometimes appears on the surface or in the interior of insulating materials. Lichtenberg figures are often associated with the progressive deterioration of high-voltage components and equipment.
The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
Picture of a Solar Compacting Trashcan Solar-powered fountain in a bird bath under shade versus direct sunlight. The following is a list of products powered by sunlight, either directly or through electricity generated by solar panels.
