Seaweed is just one of the innovations of nature from which engineers are drawing inspiration as they seek to design energy systems that are cleaner and more efficient.
As fascinating as Red Sea might be, it’s not without dangers, especially when it comes to rich underwater life. If you ever get a chance to go deep into the amazing but dangerous waters, be sure to know names and see photos of these creatures first.

An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below).
