Oxygen power plants provide an alternative energy source that is more environmentally friendly than traditional combustion engines. They use oxygen as a fuel source, heating it to produce energy through a thermal process without producing harmful emissions. The oxygen is then restored to the environment after being heated. Oxygen power plants can generate the same amount of energy as existing power plants but without using fossil fuels. They have very low operating costs and construction costs that are 2-5 times lower than other power plant types. Their specific power is similar to or higher than nuclear plants and hundreds of times higher than other renewable sources like wind and solar.
