See This Paper That Is An Energy Source

Published

on



At least once a week, Nelson Sepulveda gets on one of his bikes and rides 35 miles or more. He gets a good workout on those days, but as an associate professor of electrical and computer engineering at Michigan State University, he knows some of it is wasted energy. All of that pedaling could be harnessed and converted into electricity to power his phone or some other electronic gadget.

This week, Sepulveda and his colleagues report in the journal Nano Energy on a new film-like material capable of turning motion into electricity. The material is similar to other piezoelectrics in that it generates a voltage when it’s squeezed or pressed. But what sets this one apart is that it’s paper thin and flexible and each time it’s folded, the voltage increases.

“This increased voltage upon folding is not possible using other solid piezoelectric materials,” Sepulveda told Seeker.
If that voltage could be efficiently directed into a current, it could reduce the nuisance of recharging or even eliminate it.

‘What if you could take the mechanical energy from swiping pages on your tablet and use that to charge the battery of the device itself?” said Sepulveda. “That could reduce the time required to recharge your device.”

To create the device, Sepulveda and his team used a combination of fabrication techniques and thin layers of substances including silver, polyimide, polypropylene ferroelectret and electrically charged particles onto a silicon wafer, creating a sheet that was peeled away from the chip as if it were a sticker.

The researchers conducted a few tests using different sizes of the piezoelectic sheet to measure its voltage. In one test a palm-sized sheet cranked out about 50 volts was able to power 20 LED lights.
When they folded the film-like piezoelectric material, the voltage increased exponentially.

Although producing a high voltage is promising, said Sepulveda, it’s not enough. The researchers need to tweak the material so that its energy potential can be converted into a current. Sepulveda compared the voltage to water contained in a huge tower at the top of a mountain. The water pressure would be enormous.

“But that’s just the force,” he said.

The water’s flow — it’s current — depends on the pipes. How big are they? How long are they? What route do they take? If there are no pipes or the pipes take a convoluted route, the pressure may be very small by the time the water reaches a home faucet.

It’s the same for voltage. “I could have a million volts and no current,” he said.

Sepulveda told Seeker that he and his team have engineered at least one solution to converting the high voltage generated by the device into a flow of charge, but they were still trying to nail down the science of why it worked. He said it was too early to discuss the details.

One day soon, though, he could have a wearable device that attaches to his knee and generates power while he bikes. That would turn his 35-mile ride into an energy-harvesting bonanza.

‘That should probably give me enough energy to charge my cellphone,” he said.

TStv to Encrypt it’s Channels, roll out 62 Premium Entertainment Channels

Published

on

TStv has announced that all of it’s Television channels will be encrypted. This means that the channels on TSTV will no longer be Free-to-air (FTA). The service provider also announced that it will include 62 premium Entertainment channels in it’s collection.

TStv channels will be encrypted starting from 11:50 on November 27th. Also, the premium entertainment channels will be included to the service on 28th November. Prior to the update, viewers will have to pick up a TStv Jolly Decoder at a dealer outlet.

Owners of the Sassy Decoder are advised to visit any nearest dealer to get the decoder fully activated.

TStv currently has over 50 plus channels which in addy is the 16 premium entertainment channels coming soon.

TStv Africa is a owned Nigerian innovative Pay TV Operator that offer Pay As You View (PAYV) subscription, pause subscription, complimentary internet service and video call.

TStv sometime went out of the market due to the challenges the company faced even to the “Satellite Providers”. The good news is that they began full operation on 20th August after NigComSat offered them 5 units of 35.5MHz transponders through a collaboration with Intertel, Federal Ministry of Communications and Nigcomsat.

MTN APN Configuration That Works – Mobile and Modem

Published

on

MTN APN is what is required to enable internet connection on your phone. APN is an acronym for Access Point Name. Access Point Name is typically the name of the gateway connecting your internet enabled device to the web through an internet service provider, such as MTN.

Most often we run into the problem of missing APN configuration and can’t surf the web with our phone or modem. If you have your APN configured before now and you still cannot browse, make the listed below are in order.

  • Data subscription balance
  • Data monitor app threshold
  • Other phones of same network can browse. Your inability to browse could be a general problem from the service provider at the moment.
  • Network signal reception

In Nigeria you can fall into the hands of the wrong people, who will charge you high amount of money in the name of configuring your phone for browsing.

  Networking Device You should know (Networking 101)

To get the configuration pushed automatically to your phone by MTN.

Send as a text message “Settings” to 3888. Without quotes.

If the above method fails to get you APN configuration, you can fall back to configuring it yourself which always works.

For Mobile phones, navigate to “mobile network” in settings through more connections option, and you should see APN configuration option there.

Note: If your device works just fine, you are advised not to go further. But if for a reason you deleted the pre-installed APN configuration and you want to get it back. You’re welcome. The configurations work for 2G, 3G and 4G network type.

Access Point Name is unique to every service provider and can come pre-configured in SIM cards. When you slot in a new SIM card into a phone, it goes through it’s initiation to the service provider’s system. The service provider can then push necessary configurations to the device. Devices with MTN SIM card making an internet connection must be configured with an APN to present to MTN.

MTN will then examine this APN to determine what type of connection should be created, for example: which IP addresses should be assigned to the wireless device, which security methods should be used, etc. All of which is done in a second by a programmed system.

Airtel NG is currently giving out free 250mb data to its subscribers so long as you keep recharging your line. The good news is that you get 250Mb every week, once you meet your recharging target. All Airtel users are qualified for this promo and it gets even better because you can use the data to access any website and content.

 

You can do the recharging through your bank and still get the reward. In total you enjoy 1GB monthly for simply topping up your airtime. You can use the airtime for regular uses, such as making calls and sending text, even subscribing to a regular data plan.

  Vivo X30 is following iPhone X top notch

Speaking of the requirements to enjoy this offer, Airtel NG says you have to recharge your line consistently. Consistently in order to meet your weekly target.

How it Works:

  • To get started, you have to first recharge your Airtel line.
  • Check your weekly target by dialing *479# or check your recharge notifications.
  • Recharge to hit your target
  • Get rewarded with 250MB free.
  • Dial *123# or *140#. to check balance

Hard to say:

The free data bonus is valid till Sunday 23.59pm every week. You don’t get the reward twice a week, so no need beating the target twice. Airtel didn’t say how long the offer lasts, but it looks like one that its not going over yet. You can’t roll over any unused data. That is to say, once it expires, it’s gone, no renewals.
