  2. Power plant efficiency - Wikipedia

    en.wikipedia.org/wiki/Power_plant_efficiency

    To express the efficiency of a generator or power plant as a percentage, invert the value if dimensionless notation or same unit are used. For example: A heat rate value of 5 gives an efficiency factor of 20%. A heat rate value of 2 kWh/kWh gives an efficiency factor of 50%. A heat rate value of 4 MJ/MJ gives an efficiency factor of 25%.

    Solar generation cannot be cut off by geopolitics once installed, unlike oil and gas, which contributes to energy security. [ 162 ] As of 2022 [update] over 40% of global polysilicon manufacturing capacity is in Xinjiang in China , [ 163 ] which raises concerns about human rights violations ( Xinjiang internment camps ).

  8. Manchester code - Wikipedia

    en.wikipedia.org/wiki/Manchester_code

    Manchester coding is a special case of binary phase-shift keying (BPSK), where the data controls the phase of a square wave carrier whose frequency is the data rate. . Manchester code ensures frequent line voltage transitions, directly proportional to the clock rate; this helps clock

  9. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    This is a big advantage in mobile emergencies. The option to fill standard oxygen cylinders (e.g., 50 L at 200 bar = 10,000 L each) with high-pressure boosters, to ensure automatic failover to previously filled reserve cylinders and to ensure the oxygen supply chain, e.g., in case of power failure, is given with those systems.
