CFE admits falsifying document but maintains green energy caused blackout Utility says forgery is minor; real issue is too much renewable energy in the grid Published on Wednesday, January 6, 2021 87shares The Federal Electricity Commission (CFE) has admitted falsifying a document it used to back up its claim that a wildfire in Tamaulipas contributed to last week’s massive power outage. But the state-owned company maintains that the fire did in fact occur and that it, as well as a high concentration of renewable energy in the energy system, caused the blackout that affected 15 states. It said that a fire affected transmission lines running between Ciudad Victoria, Tamaulipas, and Linares, Nuevo León, and that the blaze contributed to the blackout that left 10.3 million customers in several of Mexico’s major cities without power for up to four hours on Monday, December 28. ....
By Garrett Reim2020-12-18T23:33:00+00:00 US Army researchers believe they have found a novel way to articulate the position of turbine blades in the hot section of jet engines. They say the innovation could significantly improve the efficiency and power of jet engines – and also enable a new, wider range of performance needed for futuristic aircraft, perhaps even new types of supersonic vertical-take-off and landing (VTOL) aircraft. Source: US Marine Corps F-35B landing vertically Jet turbine blades are typically fixed in one position. That geometry is chosen to enable the engine to perform most efficiently in one stage of flight, often cruise mode, which is the longest duration of flight. However, “this limitation creates drastic performance losses when operating away from the optimal design point, such as during take-off or landing, or when conducting sudden manoeuvring,” say US Army researchers. ....
