  • Where politicians fail, economic realities mean renewables are far less expensive: A savings of $4 billion over the next 30 years
  • Indiana is 7th in coal production and 3rd in consumption; this is due to change rapidly
  • The big winners? Solar and wind energies

  • New research from an MIT team has resulted in a proof-of-concept battery that uses a CO2-based component.
  • The research made innovative use of technology from existing carbon-capture processes and applied it to battery systems, potentially circumventing the high cost of carbon capture and the inefficiency in prior CO2-based batteries.
  • The system could be installed in power plants to capture excess carbon dioxide and use it to store energy.

  • Scientists knew that it would probably explode, but they did not expect to reach such a record magnetic field.
  • Magnetic fields are measured in teslas, after Nikola Tesla.
  • This one reached a record 1,200 teslas, 400 times stronger than an MRI; watch it explode in the video
