 The last time you switched your torch on and off, it was probably a playful mimicry of Morse. Very soon, however, you might be doing it for some serious message transmission — and that could be 100 times faster than average Wi-Fi. 

 
Scientists have finally introduced Li-Fi, a superfast new form of communication for computers, outside of labs. An Estonian start-up, Velmenni, successfully implemented this in its offices. 

According to reports in the Sydney Morning Herald, Li-Fi, which rapidly transmits data using flickering LED light fields between 400 and 800 terahertz, is nearly 100 times faster than Wi-Fi. The technology employed is known as Visible Light Communication (VLC), and is like an advanced version of Morse-code. Like switching a torch on and off in a pattern to relay a message in Morse, LED lights flick on and off in VLC at such extreme speeds that it can be used to write and transmit things in binary code, says the report.
 
Sciencealert.com reported that scientists that the researchers at Velmenni tested the technology in offices and industrial environments in Tallinn, Estonia, reaching transmission speeds of one gigabits per second, 100 times faster than the current average speeds. In lab conditions, the International Business Times (IBTimes UK) reported, the transmission speed recorded a jaw-dropping 224 gigabits per second.
 
“We are doing a few pilot projects within different industries where we can utilise the VLC technology,” IBTimes UK quoted Velmenni Chief Executive Deepak Solanki as saying. “Currently, we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a network to access the internet in their office space.”

EPA and the regulation of greenhouse gasses

This week, EPA Administrator Gina McCarthy joined private and public sector leaders for a second annual White House roundtable discussion about the progress made and new steps taken to curb emissions of hydrofluorocarbons (HFCs), potent greenhouse gases used in refrigeration and air conditioning. Administrator McCarthy announced several new actions the agency will take to help support a smooth transition to climate-friendly alternatives to HFCs. "EPA is working closely with industry leaders to reduce greenhouse gas emissions, transition to climate-friendly refrigerants, and deploy advanced refrigeration technologies,” said EPA Administrator Gina McCarthy. “The powerful combination of EPA’s regulatory actions and innovations emerging from the private sector have put our country on track to significantly cut HFC use and deliver on the goals of the President’s Climate Action Plan.” Among the actions announced today, EPA proposed a rule that would improve t...

iPad Pro Review

The iPad Pro is, at first glance, completely crazy. A giant iPad with all the limitations of iOS, coupled with added bulk that makes it harder to tote, and a price tag that starts at Rs. 70,000 , all make it a hard sell. That's only the starting price though, and you're going to end up paying a lot more for this tablet. Realistically, you should get the 128GB model, which costs Rs. 79,900, and also the Apple Smart Keyboard , which will set you back by Rs. 14,900. Artists, designers, and others might also need to buy the Apple Pencil , priced at Rs. 8,600 - which means a final price tag between Rs. 94,800 and Rs. 1,03,400. At that price, you can't really compare it to the iPad Air 2 , the last 10-inch model to be released, with an MRP of Rs. 49,900 for the 128GB variant.
