Jupiter is a bit cooler, and less gravitationally intense. But if were mining the gas giants, I hear Uranus is full of methane. (I know its funny, but its even funnier because its true!)
Now, whether we should be destroying other planets aside from "ours", that's an entirely different matter...
If we lived on them, then they would be "ours" too then wouldnt they. Besides that, there isnt really a whole lot to destroy. The surface of most of the celestial bodies in the solar system look like they were strip mined for the last billion years or so. There is no "environment" there to destroy, in fact we would be bringing an environment with us, and creating one where there was noe before, which might make up for the one were destroying down here.
It doesnt matter what its primary purpose is. The primary purpose of a sword is to kill, does that mean that I shouldnt be allowed to have a sword over my mantle? The primary purpose of botulinum toxin is to kill, does that mean botox should be pulled from the market? If people enjoy something, even if its primary purpose is something else, they should be allowed to do it, as long as they arent hurting anyone.
Its rather pointless to have flotation devices on an airline anways. If an airliner crashes at sea, its going to break up pretty horribly when it hits the water, and burning jet fuel slicks will get any of the survivors that remmain concius through the breakup.
Because this reactor will be designed to be in a rocket explosion. It will be launched before it goes critical. it wont even be turned on, and cant be turned on, until it is safely in orbit. Beyond that, there is alot more nuclear material in your nighborhood reactor than there will be in this thing.Not only that, but NASA launches over the ocean, water is a very good radiation shield. Thats why there are several nuclear submarines lying on the ocean floor that you arent worried about.
Did you miss the part of the article that said that this rice actually removes herbicide from the ground? Once your weeds are killed the rice sops up the excess and processes it into harmless chemicals. The rice had 20x less herbicide in it than conventional rice, plus the growing medium had nearly zero of the applied herbicide in it, while with conventional rice, the growing medium still contained 25% of the orginial herbicide. One of the main problems of irrigating otherwise fallow croplands is that evaporation leads to concentration of the residual herbicides and fertilizers that are applied to the ground. These run off into lakes and streams, further polluting the environment. If we can eliminate herbicide runoff from this, then we should be behind this wholehartedly, regardless of if it sells more herbicide or not.
So basically there is no danger from using black holes as a power source. Indeed, it would be quite a challenge to even do so. From the wikipedia article, the black hole would need to be fed ~10^5 kg of matter every second in order to maintain equilibrium, and would give off 10^21 Watts of power, or about 9 orders of magnitude more power than the entire human population uses now. Even containing that much power would be challenging, and if it got out of control, there wouldnt be any danger of the black hole eating the earth, but the detonation would probably kill most life on earth.
Read Earth by David Brin. Its a book about what happens when some people try to do just that, and the hole gets out of control and falls to the center of the earth.
Cheaper long distance if you use it alot (~$25 vs ~$70) Number portability (just pick up you router and move it) e-mail voicemail (my voicemail messages are emailed to me)
Heres the kicker: It says 3 times the power at the same PRICE. Not the same weight or volume They've basically found new materials that allow them to produce 3 batteries for every 1 they used to produce, and these batteries have fast recharge capabilities. Nothing to see here, move along...
I had something cool like this happen to me. I put a couple of bottles of Smirnoff Ice in the freezer to cool them dowm, but forgot about them overnight. The next morning, one of the bottles was frozen solid, but the other still appeared to be liquid. I turned the bottle over to confirm that it was, the bubble moved to the bottom of the bottle. Bu the time the bubble rose back to the top, the entire bottle froze. Coolest thing Id ever seen. Plus it woudl make a great ad for Smirnoff Ice.
Even if we burned all the oil and doubled the amount of CO2, it would reduce the amount of oxygen by 400 parts per million, thats why its not a problem
Ok, say you have a baloon, and you heat one side and cool the other (assuming the baloon doesnt pop) heres what happens. The air on the hot side gets hot and expands, increasing the pressure on that side. The air on the cool side contracts, decreasing the pressure. Thus a pressure gradient is created, and hot high pressure air moves to the cold low pressure side. The momentum of the hot air pushes the cold air, which moves towards the hot side where it is heated. As long as the air is free to move, circulation will keep the air from varying too much in temperature. Plus the baloon material provides some insulation so that the air cant transfer heat as efficiently. Vacuum is an awsome insulator. Make the outside of the capsule highly reflective and you can basically heat it with body heat and computers.

The reason they are doing this is because the DC metro is the second most utilized public transit system in the country (after NYC) When they system was originally designed in the 50's and 60's it was designed to be exxpandable to the point where you could fit 8 cars on a platform at a time, but no more. The stations are designed so that everythign is linear. There is one track in each direction, so trains cannot bypass stations (express trains) They are predicting that Metro will reach capacity on the Red and Green lines within 5 years. Once that happens, there is nothing that they can do, short of massive and expensive expansion. Raising parking fees is a good way to reduce the number of riders and increase the leeway they have with the capacity crunch.

They's stole our precious, gollum.
I hear that the pressures inside Uranus are so high, that diamonds form from the methane.
Jupiter is a bit cooler, and less gravitationally intense. But if were mining the gas giants, I hear Uranus is full of methane. (I know its funny, but its even funnier because its true!)
You should go to inkforsale.net, they have cannon tanks for ~$2
go to www.ocees.com. They already have a prototype that has better than breakeven power generation

number of possible genetic combinations: 27000! ~ infinity.
CO2= ~400 ppm
O2 = 22%

RTFA, that should clear up your questions.
isnt hydrogen already transparent? ;-)
Youve never heard of Ice Tea? Presumably you can make Ice tea with any type of tea, including earl grey, so the Hot request is not superflous.
You had me until you started talking about magnetic monopoles. Crackpot alert!
