Voltage brings new matalens into focus
Posted by Saúl Morales Rodriguéz in category: satellites
Researchers have developed a metalens that is focused using voltage instead of mechanically moving its components, a development that promises to save space and weight in numerous imaging applications.
The advance from researchers at Cornell University’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology is said to be the first of its kind.
The proof of concept could lead to a range of compact varifocal lenses for use in imaging applications including satellites, telescopes and microscopes, which traditionally focus light using curved lenses that adjust using mechanical parts. In some applications, moving traditional glass or plastic lenses to vary the focal distance is not practical due to space, weight or size considerations.

This Bonkers Tri-Wing Jumbo Jet Concept Reduces Fuel Consumption by 70%
Posted by Quinn Sena in categories: energy, transportation
The high-lift wing shapes are more aerodynamic than conventional aircraft, giving the SE200 more efficiency and shorter takeoff and landing capabilities. Courtesy SE Aeronautics.
SE points to its integrated monocoque structure as a breakthrough for performance and safety. The company notes aircraft manufacturers bolt together large sections called “barrels,” in order to maximize production. “This is usually where fuselages break apart in an accident,” SE says. “SE will build a single-piece, tough composite fuselage.”
The monocoque design and composite materials will make the aircraft the most efficient ever built, claims the company, with a 50-year service life. “We will also be able to build these aircraft in less than half the time it takes to normally build an aircraft of its size,” it says.

You Can Gas Up Your Car With Garbage, If Its The 2015 Chevrolet Impala Bi-Fuel
Posted by Quinn Sena in categories: nuclear energy, time travel, transportation
Circa 2015
With the 2015 Chevrolet Impala Bi-Fuel, drivers can top off their tank with waste byproducts, almost like Dr. Emmett Brown — aka “Doc” — did with his time-traveling DeLorean in the movie “Back to the Future.”
But instead of dumping banana peels and backwash from a beer can directly into the DeLorean’s “Mr. Fusion” reactor (see the video clip below), Impala Bi-Fuel owners simply fill up on natural gas, some of which comes from biogas, Chevy points out in its announcement about the new full-size sedan arriving in dealerships soon.

Is the Space Force about to acquire SpaceX Starships?
Posted by Genevieve Klien in categories: government, military, nuclear energy, space
NASA is already so impressed by the Starship that it has contracted SpaceX to build a lunar-landing version of it to return astronauts to the moon as early as 2024. The selection has enraged Musk’s rivals such as Blue Origin’s Jeff Bezos Jeffrey (Jeff) Preston BezosSeat on Bezos-backed space flight sells for million at auction Researchers: Wealth accumulation at Ivy League presents ‘fundamental threat to our democracy’ Democrats reintroduce bill to create ‘millionaires surtax’ MORE and has perturbed some members of Congress. Both have only themselves to blame — Blue Origin for offering an inferior design and Congress for underfunding the Human Landing System project.
Military technology development has often been defined by the advent of new ways to transport people and cargo. The racing galleon of the 16th century became the frigates and ships of the line that defined naval warfare in the 18th and early 19th centuries. The steam engine and iron and steel armor led to the dreadnoughts of the early 20th century. Modern warships incorporate nuclear power. Air travel has caused the same sort of evolution, from the motorized kites of World War I to modern jets that can deliver destruction and death from thousands of miles away.
Now, space transportation technology is poised to cause a similar revolution in the military’s ability to defend the United States and its allies and to inflict mayhem and death on any enemy that would propose to make war on America. The great irony is that the Starship will be used by a branch of the military that Musk once compared to Starfleet, the fictional service depicted in the “Star Trek” television shows and movies. The thought would likely bring a smile to the face of the franchise’s creator, Gene Roddenberry, in whatever afterlife one envisions him inhabiting.

Xenobots: Scientists create a new generation of living bots
Posted by Saúl Morales Rodriguéz in categories: biological, information science, robotics/AI, supercomputing
“These are novel living machines. They are not a traditional robot or a known species of animals. It is a new class of artifacts: a living and programmable organism,” says Joshua Bongard, an expert in computer science and robotics at the University of Vermont (UVM) and one of the leaders of the find.
As the scientist explains, these living bots do not look like traditional robots : they do not have shiny gears or robotic arms. Rather, they look more like a tiny blob of pink meat in motion, a biological machine that researchers say can accomplish things traditional robots cannot.
Xenobots are synthetic organisms designed automatically by a supercomputer to perform a specific task, using a process of trial and error (an evolutionary algorithm), and are built by a combination of different biological tissues.
