Geothermal Heat Exchanger

The geothermal heat exchanger is a machine that uses the heat from lava placed below it to heat up anything a normal boiler can, such as water, and also coolants such as coolant. When the machine is heating or boiling a fluid, the central column's cobblestone texture will be replaced with lava, and flow upwards. The three slanted cylinders will additionally rotate, both along their axis and around the central column.
Operation
The geothermal heat exchanger operates on a 15x15x10 box below it, centered under the middle of the machine. At full capacity, it generates 11250 TU/t, and does not require the full volume to be source blocks; if the topmost layer of lava were source blocks and the lower layers flowing, it would still produce full power.
