Physics of the Impossible Class 1 Impossibilities Chapter 1: Force Fields

Okay so today I am reviewing chapter one of Michio Kaku's Physics of the Impossible(ISBN 978-0-385-52069-0), and the topic is Force Fields. Force fields are a common movie and television element. They are supposed to be simple invisible and thin barriers that can deflect different types of matter, and different types of energies. This may sound easy, but recreating this can be much, much easier. Many scientists had many different ways to recreate this. Michael Faraday discovered force fields in a magnetic sense. By placing same side magnets, or a magnet and iron fillings the magnetic connection that tries to separate or link the is a force field. In the earth there is a force field of magnetism linking the atmosphere together, to protect it from harmful radiation. This type of magnetism, electromagnetism is one of physicists four forces. The other three are gravity, weak nuclear forces, and strong nuclear forces. One type of force field many think is the future force field is plasma force fields. Plasma is hotter than gas and is like an energy, like lightning. Ady Herschovitch developed a plasma window. It heats gas to 12,000 degrees Fahrient. This prevents air from coming in.  This means the inside of a plasma window is vacuum.

Plasma Window in Lab Applications

A super-hot plasma window, high energy lasers, and a protection of material stronger than steel, like carbon-nanotubes, could sucessfully burn up or stop any thing in its path. Another possibility is still found in magnetics, in a different way. Using even more advanced technology of a Maglev(found in japan and russia mostly, travels on a cushion of air due to repeling of magnets), we could have a protective barrier out of magnetism. But maglev trains cost a lot of money for all the tracks that have to be made out of a special magnetizing substance. Instead if there were such a thing as a superconductor in room temperature, abundant amounts could be produced to "paint" ordinary tracks with, creating a magnetic track, or even a magnetic levitation road, for Maglev cars. In the future about at least 100 years from know these room temperature superconductors could be found.
