2022-03-21 Reducing Humidity – Uses As Much Energy As Cooling
In air conditioning, the reduction of humidity uses as much energy as cooling. https://cleantechnica.com/2022/03/20/news-release-scientists-show-large-impact-of-controlling-humidity-on-greenhouse-gas-emissions/
2022-03-21 Muni Floating Solar Array
Cohoes, NY will use reservoir for 4 MW solar array. Quote: << “…researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made U.S. reservoirs could generate about 10 percent of the nation’s annual electricity production.” >> https://cleantechnica.com/2022/03/20/tiny-cohoes-to-floating-solar-wallflowers-catch-me-if-you-can/
2022-03-20 Climate Change “Scientist” Spencer Has Been Wrong
This video shows that climate scientist Roy Spencer was in error and has let his personal beliefs get in the way of science. This is not the way a scientist conducts science. https://youtu.be/29QDGEJC1fg
2022-03-20 Tesla Trying To Meet Battery Production Goals
Tesla is trying to meet goals for battery production. This article gets into the technical details of the wet and dry battery production, like NMP. https://cleantechnica.com/2022/03/19/can-tesla-meet-2022-goals-for-in-house-battery-production/
2022-03-20 LED Lights May Not Last As Long As Incandescent Lights
The lifetime of incandescent and LED lights is extremely dependent on the temperature at which they run – for incandescents, GE says it’s the inverse of the 7th power of the voltage – the voltage increases and the lifetime decreases. In the case of LEDs the problem is most designs sacrifice thermal management to get

2022-03-20 Solar Panel Makers May Have A Materials Constraint
This article outlines the incredibly huge amount of solar panels that China is supplying to be installed, much of them in China. The figures are astounding! Quote: << Thus far, 24 of China’s 31 provinces and regions have set out five-year-plan renewables targets which include plans for 375-420GW of solar by 2025 – around 75-84GW

2022-03-19 Pyrolysis For Recycling Wind Turbine Blades
Pyrolysis is a method that can recycle wind turbine blades. It says that wind turbine blades are responsible for 10% of the waste GFRP composites, which implies that wind turbine blades are just a small percentage of the total. https://eandt.theiet.org/content/articles/2022/03/method-for-recycling-wind-turbine-blades-almost-waste-free/
2022-03-18 Portable Micro Reactor Develops ~1 MW Electric
This portable microreactor seems a bit unrealistic. The nuclear reaction – more than 3 million watts thermal – puts out a lot of radioactivity. A reactor can’t be placed in an inhabited area without shielding. I suppose they would put the reactor several meters underground where the ground would shield the radiation from living things.
