NASA Wants Revolutionary Radiation Shielding Tech 160

coondoggie writes "Long term exposure to radiation is one of the biggest challenges in long-duration human spaceflights, and NASA is now looking for what it calls 'revolutionary' technology that would help protect astronauts from harmful exposure. 'It is believed that the best strategy for radiation protection and shielding for long duration human missions is to use electrostatic active radiation shielding while, in concert, taking the full advantage of the state-of-the-art evolutionary passive (material) shielding technologies for the much reduced and weaken radiation that may escape and hit the spacecraft.'"

All of those uses (paperweight, doorstop, therapeutic stress relief target) also apply to bricks in general, so the definition "as useful as a brick" still applies. I don't see your argument supporting your statement that the definition is nearly meaningless.
