Robots That Power Themselves

“Just like any herbivore, the EATR is programmed to forage for biomass-based food, which includes anything plant based. The job of turning biomass into energy was given to Cyclone Power Technologies. It designed a hydrogen and carbon monoxide (syngas) generator that uses external combustion to drive a steam engine, which in turn spins an alternator that generates power for the EATR’s electrical systems. ”

The article goes on to say,

“Since a furnace is less picky than internal combustion engines, the EATR can run off any type of fuel that gives off heat. It’s been calculated that about 3 to 12 pounds of dry biomass will produce 1 kilowatt-hour (kWh) of energy, or enough to drive the EATR two to eight miles. This is just one of the many applications for small steam engines. According to Cyclone, its waste heat steam engine is able to scavenge 7 hp from a diesel truck engine’s exhaust while cruising at 60 mph.”

“SOLO-TREC uses gravity, temperature, and pressure differences in the ocean, and phase-changing materials (PCMs) to power itself. The small-diameter enclosed cylinders on the outside are filled with PCM that expands and contracts about 13 percent when its temperature changes from 50 degrees to 14 degrees. Of course, most of the ocean’s water is between 32 and 35 degrees. This expansion and contraction compresses oil, which the SOLO-TREC stores in a high-pressure reservoir. When the SOLO-TREC needs power, it releases some of this high-pressure oil to drive a hydraulic motor, which is connected to an alternator. According to researchers, a SOLO-TREC will make three to four dives per day between the surface and a 500-meter depth and produce 1.6 watt-hours of power per dive to operate the onboard sensors, GPS receiver, and communication device.”

NH3 could be produced by a car on board. Then burned in an engine.
