Galaxy S II NFC capabilities inside, dormant for now

Galaxy S II NFC capabilities inside, dormant for now

If you've got either an AT&T or a T-Mobile Samsung Galaxy S II and were hoping to work with Google Wallet in the near future, you might well be in luck. Have a look under your battery cover and you'll find the three sweetest words a mobile payments seeker can ever read: Near Field Communication. It's not been highly publicized yet because plans aren't publicly solid, but take a closer look in at least one public press release and you'll see it, clear as day: NFC enabled.

Samsung Series 7 CHRONOS notebook PC Hands-on [Video]

Samsung Series 7 CHRONOS notebook PC Hands-on [Video]

A lovely set of laptops is what Samsung is presenting next here at this year's Pepcom Holiday Spectacular 2011, the Samsung Notebook Series 7 CHRONOS. This laptop comes in two sizes, one of them a 14-inch profile, the other a 15-inch profile, both of them with bigger displays than you've ever seen before in such a small set of chassis. What we get to see here isn't so much about the insides - things like the Battery Life Plus tech which keeps 80% of the cell's original capacity in a normal life cycle (this providing up to 15,000 charging cycles), instead our presenter from Samsung shows off the uniqueness in the display technology and the coolness of the chassis - well done since we've already also got an IFA 2011 look of one of the two of these notebooks in some nice photo detail as well.

Lithium Jelly Batteries are safer, thinner, and cheaper than conventional lithium batteries

Lithium Jelly Batteries are safer, thinner, and cheaper than conventional lithium batteries

Researchers from the University of Leeds have announced that they have devised a new type of battery that is safer, thinner, and cheaper to build than current lithium batteries. The new battery uses a jelly to replace the volatile liquid electrolytes used in current lithium batteries. That means that if the battery is punctured, the electrolyte will not leak.

New sensor tech uses vibrations to charge its battery

New sensor tech uses vibrations to charge its battery

I have long said that one of the technologies with the most promise to change our world is battery tech. The batteries that last longer and charge faster are key elements to improve everything from smartphones to cars. A company called MicroGen Systems has been developing cool battery tech for small, low power sensors that generates power for its on-board battery by harnessing vibrations. These batteries are ideal for low power sensors like the ones in late model cars that power the TMPS system that monitors tire pressures.

Cornell and MicroGen car sensors and instruments harvest power from road vibrations

Cornell and MicroGen car sensors and instruments harvest power from road vibrations

On a normal vehicle with a combustion engine, the power needed to operate the various instruments inside the car is not that big of a deal since you have power as long as the fuel holds out. On an EV or hybrid the less drain on the battery, the longer the driving distance so in these vehicles shedding all the power drain possible from the batteries is a big deal.

Sexy Dunhill solar charger looks like Apple gear

Sexy Dunhill solar charger looks like Apple gear

I have seen a bunch of different solar chargers for gadget and gear over the years. Generally, the folding solar chargers that I have seen or tested don’t look good and many of them have very suspect build quality. This doesn't appear to be the case with the new Dunhill Solar Charger. This thing is made from aluminum and has a leather pouch to store it in.

Apple MacBook Batteries Vulnerable To Hack

Apple MacBook Batteries Vulnerable To Hack

When we think about data security and possible vulnerabilities in our computing systems, the laptop battery generally doesn't come to mind as a hacker target. Well, security researcher Charlie Miller discovered that modern laptop batteries are just as hackable as anything else and may be far more difficult to detect, after he examined the batteries in several MacBooks, MacBook Pros, and MacBook Airs.

Suzuki shows off Every electric van in Japan

The number of EVs on the streets around the world will only continue to grow as technology improves and the EV gets more driving range and faster charging. There will come a tipping point eventually when the EV can drive long enough that consumers finally leave the range anxiety that plagues many drivers behind. Suzuki is showing off its first EVs by creating a handful of its small Every vans that are battery powered and handing them out to dealers.

Batteries that power an electric vehicle or a hybrid work best when they are cool. Keeping the batteries cool can be a big challenge in some parts of the country during the summer. Ford is getting its new Focus Electric ready to hit the market and since the vehicle will be sold all around the country Ford is working to keep the battery cool in the hotter climates.
