Fast-Charging, Noncombustible Batteries

AUSTIN, Texas — A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge.

“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted.

The researchers demonstrated that their new battery cells have at least three times as much energy density as today’s lithium-ion batteries.

The use of an alkali-metal anode (lithium, sodium or potassium) — which isn’t possible with conventional batteries — increases the energy density of a cathode and delivers a long cycle life.

Braga said that Goodenough brought an understanding of the composition and properties of the solid-glass electrolytes that resulted in a new version of the electrolytes that is now patented through the UT Austin Office of Technology Commercialization.

The engineers’ glass electrolytes allow them to plate and strip alkali metals on both the cathode and the anode side without dendrites, which simplifies battery cell fabrication.

Super-fast 5G Internet by Solar Powered Drones

In an article by BEC Crew in ScienceAlert.com it is said that Google is working on a secret project codenamed Skybender.

Super-fast 5G Internet

In the project a data transmission 40 times faster than the fastest wireless services is aimed.

The new data transmission will be made in a new spectrum with millimetric waves which covers a frequency range from 30 GHz to 300GHz.

Test are being maintained already in New Mexico.

“According to Engadget, Google has permission from the Federal Communications Commission (FCC) to continue testing their drones in US airspace till July this year, at which point we’ll probably hear more about the success or failure of Skybender. Regardless of what happens though, we get the feeling that those millimetre waves aren’t going to be left vacant for much longer.”

One of the new style smart phones is “handsfree/earsfree” Nokia FIT.

It is a concept designed by Issam Trabelsi. You can wear it to your index finger. It is very simple, but functional. It is made up of soft silicon and flexible rubber. Completely water proof. It is a minimalistic approach. You can answer calls and get informed about incoming phone calls by a vibration signal.

Epic Privacy Browser With Proxy

Epic Browser team members believe what you browse & search should always be private.

epic-privacy-browser

The program is chromium based. Privacy, speed, and security are the most important items.

They block 11 potential privacy leaks:
1- No Address Bar Suggest.
2- No URL Check.
3- Auto-Translate Removed.
4- No URLTracker.
5- Installation-ID Removed.
6- RLZ-Tracking Number Removed.
7- Default Updater Removed.
8- Installation Time stamp Removed
9- No Alternate Error Pages.
10- No Navigation Error Suggestions..
11- No Error Reporting.

The program contains a “One Click Encrypted Proxy”.

epic-privacy-browser-proxy-on

Also you can easily enable or disable plugins, data encryption, or blocking ads & trackers with the click of the umbrella icon.

epic-privacy-browser-umbrella

However, there are some articles that explain that Epic Privacy Browser have some important data leaks. Especially it is said that although some files are deleted after exiting the program, they can be easily recovered from the waste box.

Of course if your aim is not illegal, even only blocking the relation of your IP number and searches made with this IP, give you a broad invisibility. Also if you want to be completely secure, you shouldn’t connect to the internet, or try Tor.

Maybe you might give it a try: www.epicbrowser.com
