"These plans will change the face of international financial transactions," one Chinese banker said. "America and Britain must be very worried. You will know how worried by the thunder of denials this news will generate."
Russia is ready to consider using the Russian and Chinese national currencies instead of the dollar in bilateral oil and gas dealings, Prime Minister Vladimir Putin said.
...
We are ready to examine the possibility of selling energy resources for rubles, but our Chinese partners need rubles for that. We are also ready to sell for yuans," Putin said.

Maybe this is how meteorites travel from one planet to another
NASA has already rode these currents once--the Genesis probe followed a gravitational channel en-route to collecting solar dust in 2004. By following the gravitational current, Genesis reached its mission point with ten times less fuel than it would have needed otherwise.
Speaking at the British Science Festival at the University of Surrey in Guildford, Ross highlighted the convenience of these gravity tubes, but also noted that they must be utilized in conjunction with regular rockets. For instance, riding a gravity channel from Earth to Mars without any other boosts would take a couple thousand years.

Feed-in tariff approved by PUC in Hawaii
Solar energy advocates in particular are pleased that the new feed-in tariff policy preserves the existing net energy metering incentive currently available for home power producers, such as those who use photovoltaic systems. After the decision new feed-in tariff rates are determined, home power producers can decide to either run their meter backward to eliminate their power bill, or become a power producer and actually receive compensation from the utility for their clean energy.
LED light bulbs make sense now
If used an average of five and a half hours per day, the new bulbs can last up to 19 years, according to Panasonic. That's 40 times longer than incandescent bulbs.
Since you would have to buy 40 regular incandescents to do that, the price of the bulb (around $40) is about the same (40 incandescents at $1 each)
The bulbs use only an eighth the power of incandescents. That means a 60-watt-equivalent LED bulb would cost only 300 yen (about $3) a year instead of 2,380 yen ($25.80)--a significant savings over a lifetime.
This means $1,000 in electricity for the incandescent versus $100 for the LED.
They make economic sense now, especially for the few lights you leave on all the time, and the price should drop to less than 10 dollars in a few years.
