Kinetic batteries - The potential for nearly unlimited power storage

 Kinetic batteries - The potential for nearly unlimited power storage

Kinetic batteries offer a number of attractive concepts, one of the most useful which would be the very high power they could potentially store. The only limit to a kinetic battery's energy storage is how fast or how hot the storage medium can go, which in theory is limited only by the speed of light. In theory, such a battery could store energy approaching that of nuclear fuels, or even in hypothetical theory that close to anti-matter, which is millions of times that of fuel types such as gasoline or jet fuel, and hundreds of millions of times that of batteries. The energy density of hydrogen is roughly 140 megajoules per kilogram and is the most energy any chemical substance currently known can store. Jet fuel is around 40-46 megajoules along with gasoline and most other common hydrocarbons like kerosene or diesel, while ethanol has around 30. Lithium ion batteries by comparison can perhaps have .5 to 1 megajoule per kilogram, if they are relatively high end. This disparity in energy storage is why chemical energy storage, such as gasoline, is generally more efficient than chemical batteries at the moment. Lithium ion simply isn't able to store the amount of energy that
