Magnetic Pinch Could Extend Power Beaming by 100,000 Times
by Brian Wang from NextBigFuture.com on (#6G7WH)
Jeff Greason proposes extending power beaming using the magnetic pinch phenomenon. The quasar 3C273 produces a plasma jet that is 100,000 light years long. This distance would span the Milky Way. It may be possible for humans to produce pinched relativistic electron jets over the much smaller distances needed to propel a spacecraft out of ...
