The inexpensive and lightweight device which gets its power through smartphone’s audio jack, contains reagents and enzyme that create and speed up the chemical reaction that will make the blood change color in 15 minutes if the viral proteins are present. All you have to do is to offer a finger-prick of blood and press the start button.

Haktech: An air freshener research led to a fuel-cell charger discovery that can charges laptops
An air freshener research led to a fuel-cell charger discovery that can charges laptops, mp3 players, cellphones.


PowerTrekk first debuted at the Consumer Electronics Show 2012. The small device can charge cell phones, MP3 players, and eventually laptops with the addition of mere tap water. The key is a special reaction that produces hydrogen on demand, which is stored in a hydrogen fuel cell battery. All you have to do is pour water into the device to start charging whatever your heart desires (so long as it can be charged with a USB cable).
The water is confined to a PowerPukk, a small disc that holds the powder and can be sealed up after the water is added. That way you don’t accidentally spill water all over the iPhone you’re trying to charge. The PowerTrekk charger is currently available in parts of Europe and slowly making its way to the U.S., retailing for $230. By the end of this summer, you’ll be able to buy them at REI stores across the United States.
The science behind PowerTrekk was developed by Michael Lefenfeld of Signa Chemistry. Lefenfeld’s grandfather challenged him to create a bathroom air freshener, never realizing he’d wind up with reaction that could produce hydrogen.

He used his chemistry background to develop a metallic powder-based air freshener that could go in the toilet. The powder had one key problem though: When combined with water it would ignite. After some tinkering, Lefenfeld removed the combustible aspect of the reaction, but was pleased to discover he could now create hydrogen on demand.

Fuel cell company MyFC got wind of Lefenfeld’s discovering and saw the great potential in creating hydrogen by mixing water and small amounts of the metal powder. The company realized it could use the hydrogen in a fuel-cell battery set up and wound up developing PowerTrekk.
Signa Chemistry grew out of the air freshener project, becoming a full-fledged business that specializes in stabilizing reactive metals. Other companies took notice of Lefenfeld’s work for consumer applications.
Lefenfeld’s hydrogen-producing powder is also used in Pedego electric bicycles. He hopes that his chemical discovery will be used to replace “noisy gas generators,” and will push forward an overall trend of greener energy solutions.
Other fuel-cell chargers have popped up in the last few years, most notably the Horizon MinPak. The device uses a special cartridge to create hydrogen, but isn’t mass marketed. You can only purchase the MiniPak from Horizon’s website and you must inquire for pricing information.

Haktech: Enough with the rocket launch - Philippines to NoKor
Amid the failed rocket launch, the Philippine government on Friday reiterated its call to North Korea not to repeat such “threatening and provocative act.”
“The Democratic People's Republic of Korea should reconsider its current path of isolation from the international community. The Philippines strongly urges the DPRK to desist from acts of provocation and to end its use or testing of ballistic missile technology,” the Department of Foreign Affairs said in a statement.
North Korea, which defied the United Nations Security Council Resolutions, proceeded with its planned launch despite the overwhelming opposition by the international community.
“For these reasons, the Philippines deplores the launch, notwithstanding its failure,” the DFA said.
The rocket was launched at 6:50 a.m. Manila time but crashed into the western coast of South Korea after few minutes in flight.
The DFA said North Korea should "abide by the relevant UN Security Council Resolutions and abandon all existing weapons of mass destruction and ballistic missile programmes in a complete, verifiable and irreversible manner."
It added that the Philippines is ready to work with international partners in the effort to ensure peace and stability in the Korean Peninsula.
