This is definitely groundbreaking. But I don’t understand why they’re doing it this way. I think the array that’s in space should be as simple as possible – an array made up of thin sheets of metallized mylar that reflect the sunlight to the photovoltaic array on Earth. In their system and mine, there has

New research has enabled fixating nitrogen easier than by the Haber-Bosch process. About half the world’s food supply depends on the fertilizer made by the Haber-Bosch process. It is imperative that we end the use of fossil fuels in the Haber-Bosch process because its end product is CO2 greenhouse gas. It must be replaced by

This 13 minute Interview of Sir David King, explaining what *has* happened. He said that when the Greenland Ice Cap melts, the global sea level will rise seven meters (23 feet), which will dramatically change the coastlines of countries. In other words the seas will flood the cities along the coasts.
This Cleantechnica article about research and development advancements on batteries using aluminum-ion and aluminum-sulfur chemistries. German Universities; Lyten company announcing opening a pilot battery factory for lithium-sulfur cells. Quote: “”Aluminium is the most abundant metal in the Earth’s crust and its recycling is easy. Its high volumetric capacity of 8040 mA-h/cm−3 as a negative electrode
