Prometheus was a Greek Titan. Possibly one of the most important Titans as he stole fire from Zeus and brought it to the humans.
In 2079, TriCorp Industrial designed a working mobile forcefield, dubbed the Prometheus Amulet. This was not a normal forcefield, however. This forcefield would not stop bullets or push things away. It could stop one thing. Heat.
While researching plasma fields, Dr. Allan Miles stumbled on the right plasma levels mixed with electrostatic projectors to keep the superheated material from damaging the user. After many tests it was found that this "force field" could not stop physical objects, but it was adept at blocking thermodynamics in all of its forms.
The device works as a sort of heat damper. The plasma itself absorbs the heat, therefore making the power demands lesser than a normal plasma generator of its size. This allows for normal objects to enter, but strips it of nearly all of it's heat. This originally caused a problem within the bubble, as it would absorb all heat, including that within the shield. Once the electrostatic projectors were perfected, this was no longer a problem. The projectors emitted enough heat to maintain a constant 66 degrees Farenheit within the shielding. The field typically only stretches a few inches from the body of the wearer as it is projected from multiple emitters along the entire suit.
The Prometheus Amulet is more than just an amulet, it is a full body suit. It consists of a backpack that houses most of the working parts and the amulet that emits the electrostatic projections, the plasma is emitted via transmitters along the entire suit. This is more than just another heat suit. Standard heat suits of the time could protect the user to the upper end of 300 degrees Farenheit. The Prometheus Amulet suit can protect its charge around 10000 degrees Farenheit before collapsing due to overheating. This means the shield could protect a ship close to the surface of the sun for a limited time.
To date there are multiple versions; some used to encase fire in a particular area, others as portable units to surround a particular person or object and keep the heat out. Personal amulets typically weigh around 30 lbs (13kg) while industrial sized amulets can weigh in the tons. Many starships use a modified shield such as this one to protect against attacks such as those from lasers and other heat based attacks. They have not, however, found a way to stop friction and other forms of heat that originate within the protective shield.
