New Metalens technology for VR and AR

dated: 2/1/18 , 22:06
Both virtual reality and augmented reality have been around more than a couple of years at this point, but the technology is largely still its infancy. With a bulky headset required to experience the technology in the majority of cases, it feels like an older piece of equipment despite utilizing the latest advancements in technology to deliver a unique and entertaining experience. The bulky equipment required for virtual and augmented reality could change in the near future, however, with the advent of a new metalens technology.

A metalens focusing on the entire spectrum of light- including white light-was a challenge to develop, because each wavelength moves through the lens at different speeds. The differing speeds mean that the light will reach the lens at different points, which is a problem when trying to develop a metalens for AR and VR.

Traditional VR and AR devices use, "multiple curved lenses of different thickness and materials to correct these aberrations, which, of course, adds to the bulk of the device."

The metalens takes a different approach, using an achromatic lens that can produce high quality, white light imaging.

"Metalenses have advantages over traditional lenses.. Metalenses are thin, easy to fabricate and cost effective. This breakthrough extends those advantages across the whole visible range of light. This is the next big step.

A non-polluting fossil fuel technology

my 2nd post dated: 3/1/18 Scientists are developing a novel technology that may economically convert fossil fuels and biomass into useful products, including electricity, without emitting carbon dioxide into the atmosphere. Engineers at the Ohio State University in the US devised a process that transforms shale gas into products such as methanol and gasoline- all while consuming carbon dioxide. Te process can also be applied to coal and biomass to produce useful products, researchers wrote in the journal Energy & Environmental Science. Under certain conditions, the technology consumes all the carbon dioxide it produces plus additional carbon dioxide from an outside source, they said. The researchers have also found a way to greatly extend the lifetime of the particles that enable the chemical reaction to transform coal or other fuels to electricity and useful products over a length of time that is useful for commercial operation. The same team has discovered and patent...

 * According to data by the Society of Manufacturers of Electric Vehicles (SMEV), there was a 20% rise in domestic sales of EVs, despite the challenging fiscal year of 2020. * Nexzu Mobility, pune based company Started by Atulya Mittal in 2015. Previously named as Avan Motors, sells e-cycles and e-scooters. * According to Atulya Mittal on the single charge of rs.10, their e-cycles can run for 150km and scooters for 45km. For rs.50, the cycles can run up to 1000km. * Rahul Shonak, COO, NEXZU Mobility said their electric cycles are designed, engineered and manufactured in india. * Price between Rs.31,983 and Rs. 42,317, The electric bicycles are fitted with a 36 volt, 250-watt brushless DC motor and 26-inch nylon tyres.  *the e-cycles have two variants, Rompus+, and Roadlark. it has a life cycle of 750 charges, both the cycles take 3-4 hours for a full charge. *The Company's plant in Chakan in Pune has a capacity to manufacture 50,000

HOT SOLAR CELLS: 2017 TECHNOLOGIES

Image
BY CONVERTING HEAT TO FOCUSED BEAMS OF LIGHT, A NEW SOLAR DEVICE COULD CREATE CHEAP AND CONTINUOUS POWER. AVAILABILITY: 10 TO 15 YEARS Solar Panels cover a growing number of rooftops, but even decades after they were first developed, the slabs of silicon remain bulk, expensive, and inefficient. Fundamental limitations prevent these these conventional photovoltaics from absorbing more than a fraction of the energy in sunlight. A team of scientists has built a different sort of solar energy device that uses inventive engineering and advances in material science to capture far more of the sun's energy. The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use. While various researchers have been working for years on so-called solar thermophotovoltaics, the device is the first one to absorb more energy than its photovoltaic cell alone, demonstrating that the approach could dramatically increas...
