The nextgen of Solar and fuel energy.

Scientists have just discovered a way to directly convert solar energy into a synthetic fuel using carbon dioxide. Current solar technologies operate in either photovoltaic solar or thermal solar. Photovoltaic solar energy is generated through solar panels, which are typically seen on the roofs of houses and many solar plants. The other method of thermal solar is typically only used in large-scale energy plants, as it used mirrors to focus solar energy to heat a liquid which then powers turbines. Both methods, however, involve the conversion of solar energy into electricity. While electricity is useful, much energy is lost in the storing of electricity, something that the conversion process to liquid fuel overcomes.

Nice.

Elite endurance athletes could be able to keep going for longer thanks to a new drink developed to give soldiers extra energy in battle, a study using former Olympians has found.

Scientists found that cyclists using the drink, which temporarily switches the body’s energy source from glucose to ketones, could travel an extra quarter of a mile than those taking a different energy supplement.

The idea of developing the ketone drink came from the US Army’s research branch, DARPA, who invited scientists to create the most energy efficient food that soldiers could take onto the battlefield.

Hmmm.

We can rebuild him; we have the technology—but Americans question if we should in a new survey designed to assess attitudes to modern biotechnology advances.

A new report, based on a survey of 4,700 U.S. adults coming out of the Pew Research Center, looked at a range of views on certain advances in biology, with opinions split on the ethics and long-term problems associated with enhancing human capacity.

When asked about gene editing, the majority of those surveyed, 68%, said they would be “very” or “somewhat” worried about its implications.

A team built a specialized, layered structure with tiny metallic cavities that improves the light conversion efficiency by orders of magnitude.

Artist’s rendering of an incident laser beam (top of the figure) illuminating an array of nanoscale gold resonators on the surface of a “quantum well” semiconductor (slab in figure). (A quantum well is a thin layer that can restrict the movement of electrons to that layer.) The incoming laser beam interacts with the array and the quantum wells and is converted into two new laser beams with different wavelengths. Changing the size, shape, and arrangement of the resonators can be used for beam focusing, beam steering, or control of the beam’s angular momentum. (Image: Sandia National Laboratories)

The new concept explained in the studies can open doors for advanced lasers for optical communications and efficient manufacturing. It can also support efforts to miniaturize optical components for high-speed computing, telecommunications, cameras, and quantum computing that will solve computational problems currently intractable by today’s supercomputers.

Nice article; I do need to mention that more and more screen displays are moving to Q-Dot technology. So, computer graphics is being enriched in multiple ways by Quantum.

Caltech applied scientists have developed a new way to simulate large-scale motion numerically using the mathematics that govern the universe at the quantum level.

The , presented at the International Conference and Exhibition on Computer Graphics & Interactive Techniques (SIGGRAPH), held in Anaheim, California, from July 24–28, allows computers to more accurately simulate vorticity, the spinning motion of a flowing fluid.

A smoke ring, which seems to turn itself inside out endlessly as it floats along, is a complex demonstration of vorticity, and is incredibly difficult to simulate accurately, says Peter Schröder, Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics in the Division of Engineering and Applied Science.
