The construction of the photovoltaic power industry since 2000 has required an enormous amount of energy, mostly from fossil fuels. The good news is that the clean electricity from all the installed solar panels has likely just surpassed the energy going into the industry's continued growth, Stanford researchers find.
"These neon green mushrooms, or Mycena chlorophos, to use the technical term, emerge during the rainy season in Japanese and Brazilian forests, scattering the floor with glowing spores. The bases of tree trunks, fallen branches, leaf litter and moist soil provide perfect breeding grounds for the mushrooms. Found mostly on Mesameyama island in Ugui, Japan and Ribeira Valley Tourist State Park, Brazil, the appearance of these garish looking fungi is due to bioluminescence."
Heinrich Hertz (1857–1894) was a German physicist who expanded Maxwell's electromagnetic theory of light, which was 1st demonstrated by Hughes using non-rigorous procedures. Hertz is distinguished from Maxwell & Hughes because he was the 1st to conclusively prove the existence of electromagnetic waves by engineering instruments to transmit & receive radio pulses using procedures that ruled out all other wireless phenomena. The unit of frequency (cycles/second) was named the "hertz."
