Also published yesterday was a story about the MYT(tm) Engine (Massive Yet Tiny, by Angel Labs LLC), which also has application as a pump or compressor. The company says the engine as a pump/compressor is able to combine all three key elements of pumping/compressing — pressure, volume, and flow — into one device, making it the ideal candidate for applications like pumping and retrieving pressurized air from wind turbines into underground chambers, making the storage cycle much more efficient and cost effective. Yesterday's article was about applying the MYT engine technology to geothermal energy harvesting. On May 15, 2010, Angel Labs will be demonstrating its engine to the Oregon Section of the Society of Automotive Engineers. The MYT (Massive Yet Tiny) Engine by inventor Raphial Morgado, is an award-winning internal combustion engine of new design that features multiple firings in one cycle, producing enormous torque in a small area. They claim 40 times higher power to weight ratio, low parts count, low maintenance, high mechanical efficiency, and low pollution.

The hot water and minerals would be brought to the surface to turn turbines. The vent output is very consistent and energy dense and at very high volumes. This is a brand new, previously untouched, energy source — a discovery on the scale of man's harnessing nuclear power, but cleaner and potentially cheaper. National Geographic estimates the power of just the known worldwide vents at around 17 million megawatts, with thousands of miles of ocean still unexplored. It's difficult to estimate the quality and number of vents that are convenient enough to be practical, but Marshall believes that several thousand gigawatts of power are recoverable worldwide-- the equivalent of perhaps 1,000 or more nuclear power plants. Also, as the hydrothermal fluid rises it carries with it some of the richest ores to be found anywhere, laden with just about every metal and mineral that we mine the surface for now. Anyone have a few spare billion to help build the pilot plant?
