20 second charger – Teen’s invention could charge your phone in 20 seconds

daily alternative | alternative news - 20 second charger - Teen's invention could charge your phone in 20 seconds

Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student’s invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.

The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time.

What’s more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to Eesha Khare of Saratoga, Calif.

“My cellphone battery always dies,” she told NBC News when asked what inspired her to work on the energy-storage technology. Supercapacitors also allowed her to focus on her interest in nanochemistry — “really working at the nanoscale to make significant advances in many different fields.”

To date, she has used the supercapacitor to power a light-emitting diode, or LED. The invention’s future is even brighter. She sees it fitting inside cellphones and the other portable electronic devices that are proliferating in today’s world, freeing people and their gadgets for a longer time from reliance on electrical outlets.

“It is also flexible, so it can be used in rollup displays and clothing and fabric,” Khare added. “It has a lot of different applications and advantages over batteries in that sense.”

Google Upgrades Digital Wallet to Pay by Facial Recognition

As we march steadily toward a cashless society, Google is naturally at the forefront of seeing it come to fruition as quickly as possible.

Despite the fact that several years ago Google had a major security scare with its first incarnation of the digital wallet smartphone app, which required a temporary shutdown, they are announcing a new system being tested which does not even require the smartphone at all.

A growing number of people apparently find that having to remove their smartphone is just such a hassle that they are prepared to embrace payment via biometrics – in this case, facial recognition.

As a perfect indicator of the target market, please read this sad quote:

“Imagine if you could rush through a drive-thru without reaching for your wallet, or pick up a hot dog at the ballpark without fumbling to pass coins or your credit card to the cashier,” Bhat said. (Source)

In one sentence, that quote might represent literally everything that is wrong with modern society.

The new system is being cleverly called Hands Free; and, as the second indicator of its potential mass appeal, it will be rolled out first at McDonald’s and Papa John’s fast food restaurants.

A second more serious component to this ties in with the recent rollout of citywide WiFi systems that keep people connected at all times. Layered on top of that is the arrival of billboards with hidden cameras built in that can film you, then track you through your mobile phone. This reality makes the following information more chilling than convenient:

The digital wallet uses Bluetooth and Wi-Fi connections alone [sic] with location sensing capabilities in smartphones to detect when someone is near a store enabled with Hands Free payment technology.

“When you’re ready to pay, you can simply tell the cashier, ‘I’ll pay with Google,’” Bhat said.

“The cashier will ask for your initials and use the picture you added to your Hands Free profile to confirm your identity.”

At some locations, Google is experimented [sic] with using cameras in stores to recognize people with Hands Free digital wallets so they could pay without even pausing. (emphasis added)

The number of people already prepared to accept this system numbers in the millions, according to Google.

Although this announcement would appear to border on satire, please view the videos below to get an idea about a world where cash is seen as a major annoyance, and laziness is embraced as a virtue.
