Researchers have created a device called a ‘shadow-effect energy generator’ that makes use of the contrast in illumination between lit and shadowed areas to generate electricity. This novel concept opens up new approaches in harnessing indoor lighting conditions to power electronics.

Shadows are often associated with darkness and uncertainty. Now, researchers from the National University of Singapore (NUS) are giving shadows a positive spin by demonstrating a way to harness this common but often overlooked optical effect to generate electricity.

“Shadows are omnipresent, and we often take them for granted. In conventional photovoltaic or optoelectronic applications where a steady source of light is used to power devices, the presence of shadows is undesirable, since it degrades the performance of devices. In this work, we capitalised on the illumination contrast caused by shadows as an indirect source of power. The contrast in illumination induces a voltage difference between the shadowed and illuminated sections, resulting in an electric current. This novel concept of harvesting energy in the presence of shadows is unprecedented,” explained research team leader Assistant Professor Tan Swee Ching, who is from the NUS Department of Materials Science and Engineering.

No matter how they may make you feel, licking your gadgets and electronics is never recommended. Unless you’re a researcher from Meiji University in Japan who’s invented what’s being described as a taste display that can artificially recreate any flavor by triggering the five different tastes on a user’s tongue.

Current methods for charging electronic devices via wireless technology only work if the overall system parameters are set up to match a specific transfer distance. As a result, these methods are limited to stationary power transfer applications, which means that a device that is receiving power needs to maintain a specific distance from the source supplying it in order for the power transfer to be successful.

Researchers at Stanford University have recently developed a new technique that could enable more efficient wireless power transfer regardless of the distance between a device and its power source. Their paper, published in Nature Electronics, could help to overcome some of the current limitations of existing tools for the wireless charging of elecronic devices.

“The main purpose of our study was to overcome the barrier to dynamic wireless charging,” Sid Assawaworrarit, one of the researchers who carried out the study, told Phys.org. “Our idea is based on parity-time symmetry (PT symmetry), which concerns systems with balanced gain and loss.”

The city’s Convention and Visitors Authority is still planning to open the ‘Loop’ in January 2021, in time for the Consumer Electronics Show — if the trade show still happens, that is. The plan is to whisk passengers through the tunnels that run underneath the Las Vegas Convention Center using a mix of Model 3s, Model Xs, and a 16-passenger “tram.”

Idk if this is real or not but I think it could be o.,.o.

Just about everyone has had the experience of blinking while having their picture taken. The camera clicks, your eyes shut, and by the time they open again, the photo is ruined. A new ultrafast camera developed at Caltech, were it aimed at your lovely face, could also capture you looking like a dunce with your eyes shut, except instead of taking just one picture in the time it takes you to blink, it could take trillions of pictures.

The new camera developed in the lab of Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering in the Andrew and Peggy Cherng Department of Medical Engineering, is capable of taking as many as 70 trillion frames per second. That is fast enough to see waves of light traveling and the fluorescent decay of molecules.

The camera technology, which Wang calls compressed ultrafast spectral photography (CUSP), is similar in some respects to previous fast cameras he has built, such as his phase-sensitive compressed ultrafast photography, or pCUP, device, which can take 1 trillion frames per second of transparent objects and phenomena.

Islamic religious scientist points out a hidden existential threat, worse even than the SARS-CoV-2 virus: two-legged viruses that spread liberal democracy.

Iranian scholar Alireza Ebadi, Supreme Leader Ayatollah Ali Khamenei’s representative in the Southern Khorasan Province, said in a lecture that aired on Khorasan Jonoobi TV (Iran) on April 10, 2020 that the “virus” of Western liberal democracy is even worse than the coronavirus since it has caused the deaths and displacement of millions of people, two world wars, coups in various countries such as Iraq, the spread of cholera in Yemen, and Western intervention in Syria, Afghanistan, India, Pakistan, and elsewhere. Ebadi expressed hope that once humanity defeats the “pest” of the coronavirus, it will “make sure the greatest pests of all do not escape.” He added: “May God [save] humanity from [the] two-legged viruses.”

DisplayPort Alt Mode 2.0 is a new standard from the Video Electronics Standards Association that allows USB 4 to offer all the bells and whistles of the DisplayPort 2.0 standard as well as transmitting USB data. That means support for 8K displays at 60Hz with HDR, 4K displays at 144Hz with HDR, or even 16K (15360×8460) displays at 60Hz with compression. It’s a big step towards USB Type-C becoming a true jack-of-all trades connector.

The USB 4 spec can already transmit DisplayPort data, but AnandTech reports that the new standard remaps USB-C’s high speed data pins to unlock more bandwidth for video. USB 4 is bidirectional, meaning it can carry up to 40Gbps of data in either direction. However, video doesn’t need to go both ways — you only really need data to pass from your laptop to your monitor (for example). This alt mode means that all that bandwidth can be used to just send video one way, meaning you get a maximum raw bandwidth of up to 80Gbps.
