US police ‘shot dead in ambush’ in Washington state

Four police officers have been shot dead in an ambush at a coffee shop in Washington State, police say.

Officials said at least one gunman walked into a coffee shop in Parkland, near the McChord Air Force Base, and opened fire.

A sheriff’s spokesman said the officers had been targeted and it was not believed to have been a robbery.

Other customers were in the coffee shop at the time but no-one else was injured in the attack.

Parkland is in Pierce County, 40 miles south of Seattle.

Pierce County Sheriff’s spokesman Ed Troyer said the officers had been working on their laptops in the coffee shop when the shooting happened on Sunday morning.

“It was just a flat out ambush,” he said. “None of the employees or any of the people inside the store were targeted or hit or wounded.

“So we believe this was a cold, calculated killing of four police officers.”

First reports said there had been two gunmen but Mr Troyer told the BBC he now believed there was only one.

He said the suspect is a black male in his late 20s or early 30s who was scruffy, wearing a black coat and blue jeans.

Families of the four officers were being informed.

Theron Zahn, of KOMO-TV, told the BBC that a huge police operation involving hundreds of officers was under way.

“Police helicopters are in the air using their infra-red cameras for anyone who may be hiding nearby. It is a massive manhunt.”

Police are offering a $10,000 reward for information leading to the arrest of the gunmen.

Scientists Make Fuel from CO2 Emissions and Sunlight : Gas 2.0

Scientists from Sandia National Labs have successfully field-tested a machine that uses solar energy to convert CO2 waste from power plants into fuels such as gasoline, diesel, and jet fuel.

Cylindrical in shape, the device has both a hot and cold chamber with 14 Frisbee-like rings in the middle. The rings’ outer edges–made of iron oxide–are solar heated to 2,700 degrees which forces the composite to lose oxygen atoms.

As the rings rotate (one revolution a minute), they move in towards the cool chamber. There, carbon dioxide is added and the iron oxide composite takes back its missing oxygen atoms. The resulting carbon monoxide would be used in creating a synthesized liquid combustible fuel.

Invented by Rich Diver, we first discussed the device in January of last year. Until recently, it had only been tested in a laboratory. But a fully hand-built, and much larger, version was just successfully tested. “This is a first-of-its-kind prototype we’re evaluating,” Diver explains.

The device is called the Counter-Rotating-Ring Receiver Reactor Recuperator or the CR5 for short. I think we’ll stick to that shorter title for now. This method of forced-photosynthesis was initially designed for creating cheap abundant hydrogen fuel.

 

“In the short term we see this as an alternative to sequestration,” SNL Advanced Materials Laboratory chemical engineer James Miller, who has also been part of the research, adds.

This type of CO₂ recycling could take trapped carbon waste from power plants and then returned for production, instead of releasing it to the air. Though, the resulting syngas does just burn right back into CO₂–not exactly ideal.

Regardless, we’re looking at 15-20 years before the tech is market ready. Researcher’s hope to achieve an efficiency of a few percent which is about double that of real-world photosynthesis.  …
