Nature – Physicists create Star Wars-style 3D projections — just don’t call them holograms Smalley’s team has taken a different approach — using a technique known as volumetric display — to create moving 3D images that viewers can see from …

futureNanoparticle gel could make mass-market low-cost Holography, LIDAR

0
Why aren’t holograms or related optical devices part of our everyday lives yet? The technologies can be created by using magnetic fields to alter the path of light, but the materials that can do that are expensive, brittle and opaque. …

futureChina’s J-20 stealth fighter spotted with four extra fuel tanks for extended range

0
China’s J-20 stealth fighter has been seen with four auxiliary fuel tanks (aka, drop tanks or “bags”) under its wings. Although cumbersome external fuel tanks sap the J-20’s low observable (stealth) qualities and maneuvering performance, it is likely that they …

hologramsMembrane solves one of the major technical barriers to commercialization of the lithium sulfur battery

0
Researchers developed an alteration to the lithium-sulfur battery that could make it more than competitive with the industry standard lithium-ion battery. The lithium-sulfur battery, long thought to be better at energy storage capacity than its more popular lithium-ion counterpart, was …

hologramsOne micron thick solar cells and three micron thick OLED displays

Scientists in South Korea have made ultra-thin photovoltaics flexible enough to wrap around the average pencil. The bendy solar cells could power wearable electronics like fitness trackers and smart glasses. Thin materials flex more easily than thick ones – think …

augmented realityDARPA wants artificial intelligence to explain conclusions and reasoning to humans

0
DARPA wants to have artificial intelligence have the capability of explaining and helping humans to trace the conclusions, decisions and reasoning of the AI. Dramatic success in machine learning has led to an explosion of new AI capabilities. Continued advances …

algorithmCompact spherical tokamak would be 100 times smaller than ITER and has a chance to start operating decades earlier

0
Startup company Tokamak Energy has published three papers showing size is not an important factor in fusion reactors and proving that a compact spherical tokamak reactor can produce high power. This turns the pursuit of fusion into a series of …

astronomyThermal energy harvesting antennas by more than 10,000 to 100,000 times with tiny holes in copper

0
Current rectenna designs work best at lower frequencies. Yet waste heat from hot objects can push into the 100 THz (100 trillion cycles per second) range. Park and his colleagues found a way to enhance thermal emission of hot bodies …
