  2. Stirling radioisotope generator - Wikipedia

    en.wikipedia.org/.../Stirling_radioisotope_generator

    A Stirling radioisotope generator (SRG) is a type of radioisotope generator based on a Stirling engine powered by a large radioisotope heater unit. The hot end of the Stirling converter reaches high temperature and heated helium drives the piston, with heat being rejected at the cold end of the engine.

  3. Wave disk engine - Wikipedia

    en.wikipedia.org/wiki/Wave_disk_engine

    A wave disk engine or wave disk generator is a type of pistonless rotary engine being developed at Michigan State University and Warsaw Institute of Technology. The engine has a spinning disk with curved blades. Once fuel and air enter the engine, the rotation of the disk creates shockwaves that compress the mixture.

  4. Advanced Stirling radioisotope generator - Wikipedia

    en.wikipedia.org/wiki/Advanced_Stirling...

    Cutaway diagram of the advanced Stirling radioisotope generator. The advanced Stirling radioisotope generator (ASRG) is a radioisotope power system first developed at NASA's Glenn Research Center. It uses a Stirling power conversion technology to convert radioactive-decay heat into electricity for use on spacecraft.

  5. Hail cannon - Wikipedia

    en.wikipedia.org/wiki/Hail_cannon

    A hail cannon is a shock wave generator claimed to disrupt the formation of hailstones in the atmosphere. These devices frequently engender conflict between farmers and neighbors when used, [ 1 ] because they are loudly and repeatedly fired every 1 to 10 seconds while a storm is approaching and until it has passed through the area, yet there is ...

  6. Applications of the Stirling engine - Wikipedia

    en.wikipedia.org/wiki/Applications_of_the...

    Based on the companies' published performance specifications, the off-grid diesel-fueled unit produces combined heat (5.5 kW heat) and electric (800W electric) output, from a unit being fed 0.75 liters of automotive-grade diesel fuel per hour.

  7. ALCO S-2 and S-4 - Wikipedia

    en.wikipedia.org/wiki/ALCO_S-2_and_S-4

    The locomotives' exterior was styled by ALCO engineer Ray Patten, who used curves in a mild application of Art Deco principles. The S-2 and S-4 are distinguishable externally from the very similar S-1 and S-3 660 hp (492 kW) switchers in that they have a larger exhaust stack with an oblong base and a larger radiator shutter area on the nose sides.

  8. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).
