With the ability to capture, store, and release energy
The Biblical Ark of the Covenant once stood in the Tabernacle in the Sinai wilderness.The Ark that led Moses and the Israelites into the Promised Land and also was housed in the legendary Temple of Solomon. The exterior of the Ark was gold, the best conductor of electricity and lined with Acacia wood, an excellent insulator. An electrical charge would accumulate from the constant exposure to static electricity in the dry desert climate. Over the ark, the wings of the Cherubim could form a sparking gap, producing a dynamic radiance that would inspire awe in the observer, and could easily emit an electrical discharge that might be dangerous.
An Egyptian version of the Ark of the Covenant. Just like today’s batteries, the larger the capacitor the higher the voltage, and the more electrons that are available to discharge. Another form of creating or generating more powerful forms of electricity would be to make them bigger and capable of holding more voltage.
A portable container that looks like an ark, with a figure of the Egyptian god Anubis, that is made of wood and covered with gold foil, line with stucco, tar, gold leaf, silver, quartz and obsidian that fits the profile of a powerful electrical capacitor.
A drawing of an Anubis “ark” placed inside what we would call a Faraday cage. This could be a way to increase the electrical charge inside the protected cage. There are many stories about the Ark of the Covenant as an electrical capacitor that could be dangerous as its electrical energy could be fatal.
