Some Soviet satellites used nuclear fuel to provide power for their satellites. One in particular returned to Earth spreading radioactive debris across Canada. A safer alternative might be to attach robot boosters to these and other satellites to boost them into deep space or the sun. Some old satellites might be able to be used to act like Shephard moons to catch debris as they travel around the planet. Debris colliding from behind might cause too much damage, but if a satellite were to "catch up" with the debris, velocities might be low enough to allow the debris to imbed itself without causing serious damage. Future specially designed "shephard satellites" could use large panels in place of solar arrays to capture debris. Starting in a high orbit, orbital decay could be used to reduce altitude while debris is being collected. Once fully loaded the satellite could then be sent into deep space. L.David Korkia

In an earlier post, i suggested the possibility of building a Hybrid solar wind turbine. This would incorporate solar cells into the blades of a wind turbine. This would allow its use in areas where either technology might not suffice alone. I would like to expand on this concept to include the pylon supporting the turbine. L.David Korkia

Reading the article about the next stealth bomber raises some questions to. One concerns using a wolfpack formation for greater defense. I assume that the military has already done studies on reducing or eliminating the turbulence that results from the plane as its flying air being drawn into the engines and exhausted. First question is what happens when the turbulence from several stealth aircraft flying close together commingles? Will this set up turbulent airflow patterns that can be seen on Doppler Radar, even if you can't see the planes themselves. Next question is how did they determine what the Radar signature of a mosquito looks like? The mosquito analogy suggests that a Radar signature exists, but how many mosquitoes fly over 600 mph. It seems that if you have software that keeps track of a signature's velocity, this would give its true identity, even if it appears like a mosquito or a bird. Last question. There is mentioned the possibility that the new bomber will be unmanned, but this might cause a stir of Capitol hill if used to carry nukes. But aren't ICBMs unmanned ? What logic are they using to differentiate the two. Both can crash or blow up. But at least you can call the bomber back.
