Fwd: easy C02 to fuel


'Proven one-step process to convert CO2 and water directly into liquid hydrocarbon fuel

A team of University of Texas at Arlington chemists and engineers have proven that concentrated light, heat and high pressures can drive the one-step conversion of carbon dioxide and water directly into useable liquid hydrocarbon fuels.

This simple and inexpensive new sustainable fuels technology could potentially help limit global warming by removing carbon dioxide from the atmosphere to make fuel. The process also reverts oxygen back into the system as a byproduct of the reaction, with a clear positive environmental impact, researchers said.

"Our process also has an important advantage over battery or gaseous-hydrogen powered vehicle technologies as many of the hydrocarbon products from our reaction are exactly what we use in cars, trucks and planes, so there would be no need to change the current fuel distribution system," said Frederick MacDonnell, UTA interim chair of chemistry and biochemistry and co-principal investigator of the project.

In an article published today in the Proceedings of the National Academy of Sciences titled "Solar photothermochemical alkane reverse combustion," the researchers demonstrate that the one-step conversion of carbon dioxide and water into liquid hydrocarbons and oxygen can be achieved in a photothermochemical flow reactor operating at 180 to 200 C and pressures up to 6 atmospheres.'

Fwd: China

''China's South China Sea military deployments are no different from U.S. deployments on Hawaii, the Chinese Foreign Ministry said on Monday, striking a combative tone ahead of a visit by Foreign Minister Wang Yi to the United States this week.

The United States last week accused China of raising tensions in the South China Sea by its apparent deployment of surface-to-air missiles on a disputed island, a move China has neither confirmed nor denied.

Asked whether the South China Sea, and the missiles, would come up when Wang is in the United States to meet Secretary of State John Kerry, Foreign Ministry spokeswoman Hua Chunying said Washington should not use the issue of military facilities on the islands as a "pretext to make a fuss".

"The U.S. is not involved in the South China Sea dispute, and this is not and should not become a problem between China and the United States," Hua told a daily news briefing.

China hopes the U.S. abides by its promises not to take sides in the dispute and stop "hyping up" the issue and tensions, especially over China's "limited" military positions there, she said.

"China's deploying necessary, limited defensive facilities on its own territory is not substantively different from the United States defending Hawaii," Hua added.

U.S. ships and aircraft carrying out frequent, close-in patrols and surveillance in recent years is what has increased regional tensions, she said.

"It's this that is the biggest cause of the militarization of the South China Sea. We hope that the United States does not confuse right and wrong on this issue or practice double standards."
