The Thorium cell is the 7th heat producer and 8th producer overall. It Cost 50 Trillion Research Points to unlock. Thorium Cells have a base heat value of 150 Billion, It lasts for 800 ticks and costs 72 Trillion. In a single lifetime the Thorium cell will produce 120 Trillion heat/power or 120 Trillion Cash. When upgrading the cells heat production, it increases at 25% per level. The Thorium Cell has a new ability that no other heat producer has had before it. Thorium can distribute heat up to a distance of 2 tiles. Researching Thorium Cells gives access to research Office 5, Underground Heat Pipes, Generator 4, and Protactonium Cells.
