  • A new paper outlines using the the Mountain Gravity Energy Storage (or MGES) for long-term energy storage.
  • This approach can be particularly useful in remote, rural and island areas.
  • Gravity and hydropower can make this method a successful storage solution.

  • A solar-powered airship built by a U.K.-based company could be a groundbreaking way to freight cargo internationally with lower emissions, and a big step towards a 100 percent renewable world.
  • Varialift's airship will use helium gas to lift off, which is a great deal safer than the hydrogen that airships of the past used.
  • It's been estimated that the cost of the Varialift aircraft would be comparable to a jumbo jet.
