Obama is a Lightning rod.. The believers on both sides of the fence debate him with great enthusiasm.. Socialist says the Right, Give him a chance says the left.. but in Reality based solely on his administration choices and his first 5 Months..President Obama would seem to be President Next .. on the Neoliberal/Con bus.Not a whole lot of substance behind all that passionate campaigning unfortunatelyIs Mountain Top removal the best example of our man looking the other way.. ?
I also despise car alarms and think they are a major cause of noise pollution. I have to admit that, sometimes when an alarm goes off outside my office, I hope the thief disables it quickly. Yeah, I know it's not right, but so many people have their alarm's sensitivity set so high that it will go off whenever a truck passes or even a jet flies by. What's up with that? The other responders who say an alarm can be an effective deterrent are correct, of course. And yes, my SUV has an alarm. Good question.
This is a very good idea. It would be the most efficient powerplant possible, because it converts all the mass you throw in into energy. - Create a black hole: This is a practical impossibility at the moment. You could make a small BH in an accelerator and feed it to the appropriate size. - Containment: BH's can have charge. A charged object is easy to contain in an electric field. This is not a problem. - You don't have to surround the BH with a mirror. You can keep it in equilibrium by throwing the right amount of mass in. - The design: A BH surrounded by a material that absorbs the radiation and heats up. You convert the heat into electricity with a steam turbine. - Calculations: If I did this correctly, a black hole with its radiation peaked around an energy E in electronvolts has a mass of M 10^20 * 1/E(eV) kg The power output of the BH radiation is P 10^-7 * E(eV)^2 W Visible light (~1 eV): easy to absorb; M 10^20 kg; P 10^-7 W. Electrons Positrons (~1 MeV): positrons are annihilated; you should capture the resulting gamma radiation; M 10^14 kg; P 10^5 W. These masses are too high. You will also lose efficiency when particles are produced that you can't capture, like neutrino's or fast muons. For a managable mass of M 10^4 kg the energy of the radiation is E 10^7 GeV. This energy is too big. The evaporation time of a BH is t 10^-16 M(kg)^3 seconds This means that you can never make a black hole starting with a small one. So my first point was false. - Conclusion: Theoretically it is possible to operate such a powerplant, but the mass or energy output is not managable by mankind. It is not possible to build the powerplant.
