  1. Imagine how much gas we would all save.... accidents wouldn't kill people... we would all live much closer to work.... AND we all might get skinny in the process 😉
  2. , em vez de gastar milhões em marketing com jogadores de futebol, artistas, políticos, sem falar gastos com arte de gosto duvidável, o banco fez algo que jamais será esquecido pelos seus clientes. É Natal!Incrível !!! 1507940147251-drlcss.mp4
  3. My heart would be pounding scared.... hard to believe anyone would take a group in such a vehicle???
  4. @devarajjh how much is that in USD? Just curious.
  5. Since then it climbed to the high $3 range.... and now it is going lower again.... I saw this more recent post: The rumor is that the price will go even lower and then skyrocket. I love that answer.... Prices will go up and down. (so insightful! 😉
  6. I just read the following on another forum talking about the long term prospects for Earth: "...And we’re cooling off down below at a far faster rate (about 5x) than the sun is warming up. The point is… in about a billion years… maybe 1.5 (we’re still measuring and guessing to be honest)… the Earth will be very cold, with most of our remaining water trapped permanently below the surface as part of the lithosphere. We won’t be much better off than mars is now. And as the dynamo at the center of the earth wanes (and it is), the magnetic field that keeps the sun from punishing our atmosphere worse than it already does will no longer be up to the job… so not only will the crust beneath our feet by cold, but the air will be a looooot thinner (and thus also cold.) Radiation will get through much more easily and you’ll be lucky to see an equatorial summer’s afternoon reach 10C. Of course, dry as as a bone as it would be, you probably wouldn’t see any liquid water anyways… not even at high noon." ---------------------------------------------------- So ... Could Global Warming end up being a good thing for planet Earth long term?
  7. The humble pine cone is more than a holiday decoration. It's an ancient form of tree sex. Flowers may be faster and showier, but the largest living things in the world? The oldest? They all reproduce with cones.
  8. How to make hobby rocket “sugar motors” using sugar and kitty litter, that shoot up over 2,300 feet high, and cost less than $0.50 to make.
  9. Our star will expand into a red giant in about 4.5billion years. At this point will extend to 0.8AU or more. 500,000 years later it will shed the outer layers of gas(think of it like an onion) and the end result will be two things. 1: a planetary nebula 2: a White Dwarf A white dwarf is the core of the star and since it was the core, it is still very very very hot. It can easily be about 40,000K which is about 4000 x the boiling point of water. Since these objects are no longer generating heat they’re cooling down. But since space has no air they only way they cool down is via radiating the heat out. The time it will take for a white dwarf to cool to 2K is over 10,000,000,000,000 years, yup. They will take longer to cool than the universe has been around for. In the future when their is not enough Hydrogen to form any new stars the only thing that will be left is these white dwarfs. Once these reach 0K the universe will be dead, black.
  10. National and international efforts to develop new sources of carbon-free energy are exploring a nuclear power concept first introduced in the 1950s and 1960s: the Molten Salt Reactor. This design is vastly different from our current light water nuclear power plant and is inspiring a fresh look at the technology. Researchers at Pacific Northwest National Laboratory are working on many solutions necessary for the design, construction, and operation of a full-scale molten salt reactor. We have expertise in radiochemistry and real-time online monitoring, as well as materials design and performance testing.
  11. Dude! Poison nerve agent?! Seriously? Hold my beer. or I enjoyed those dismembering pics you sent. Thank you! or Do we know how to take care of pesky journalists or what?
