ok so it takes heat energy that is in the background code wise and converts that heat into electric right now the engine is still being updated and worked on in my spare time as for animation it has none it is just a static as for the icon not being presented i have no idea why and the code is broken as of right now the heat doesn't really need to be added to the engine for it to work at the moment it acts like a accumulator plus electric generator currently it produces 600MW and as for the icon that it wants electricity it is not wanting it wants to provide just connect it to a power pole and see also the flashing icon is the same if you place a steam engine down without a pole next to it same with any electric provider
