Summary #704

Solar energy becomes biofuel without solar cells
  • Researchers have produced microorganisms that can efficiently create butanol using only carbon dioxide and solar energy.
  • They are cyanobacteria built to specialise in producing energy, developed with the help of synthetic biology and genetic modifications.
  • Cyanobacteria are the most efficient photosynthetic organisms on Eearth.
  • The modified bacteria is efficient enough that it could be used to produce fuel, or components for tyre rubber.
  • It could also potentially be used in industries with large greenhouse gas emissions to significantly reduce them.
