Boeing patents 'Star Wars'-style force fields

[n2doc]

A new patent granted to aircraft, defense and security company Boeing is taking its cues from science fiction. Just like the glowing energy shields seen protecting troops, machines and even spacecraft in Star Wars and Star Trek, the design -- named "Method and system for shockwave attenuation via electromagnetic arc" -- uses energy to deflect potential damage.

As it is described, the system is not designed to prevent direct impact from shells or shrapnel; rather, it is designed to protect a target -- such as a vehicle or building -- from the damaging effects of shockwaves from a nearby impact.

The patent is for a shockwave attenuation system, which consists of a sensor capable of detecting a shockwave-generating explosion and an arc generator that receives the signal from the sensor to ionise a small region, producing a plasma field between the target and the explosion using lasers, electricity and microwaves.

This small plasma field would differ from the surrounding environment in temperature, density and/or composition. This would provide a buffer between the target and the explosion that would hinder the shockwaves from reaching and damaging the target.

1. They need to work on the micrometeorite deflection problem

before we get much farther off this planet in our frail bodies.

2. Sorry to burst your bubble, but they patented the IDEA of having a force-field.

Here's the patent.
No specs on engineering.
No calculations how much they would need of something to achieve something.

What if it takes a generator the size of a truck to create a plasma-shield strong enough to protect you against the shockwaves of a boom-box?

There is no there there.

Boeing patented the concept of using a plasma-wave to disperse an incoming shockwave.

There is no guarantee there will ever be a working device. It's purely hypothetical at this point.




But hey, they have 20 years to figure it out before the patent becomes invalid.
