The quest for power will corrupt us all. As we find that more and more portable electronic devices are becoming part of our daily life and wardrobe, the need to find power and ensure they're always charged grows ever more important.
But with an increasingly mobile lifestyle matching concerns about the environment, no one really wants to be tethered to a wall socket or docking station. Enter, then, the new field of solar-powered clothing. The idea is simple -- place solar panels on your jacket or bag, and your devices can charge as you go about your day.
ScotteVest, of Idaho -- already well-known among the gadget-conscious as the manufacturer of clothing with large numbers of hidden pockets specifically designed to carry electronic devices -- has released a solar panel-equipped version of its Version Three jacket.
The large microfiber waterproof comes with a removable section that slings solar panels across the wearer's shoulders and back.
Integral wires and a battery pack built into the jacket mean your devices charge inside your pockets, so you can use them at the same time.
We couldn't try out the Scotte-Vest, so we can't say if it's any good or not. But we could try out an engineering sample from another company, Voltaic Systems, and their range of solar-powered backpacks.
This is a lovely bag -- large enough to fit a Powerbook and with a pocket layout obviously designed by people who use such bags every day. Great padding and a ballistic nylon shell add to the heavy-duty feel. But it's the solar panels that make the bag stand out. They're arranged along the back, inside a panel that zips down along three edges to reveal a battery pack, a cigarette lighter-style terminal and some pockets for your devices and the set of converter plugs that comes with it. The wiring is integral to the bag, with one charge point mounted on a shoulder strap next to the mobile-phone pouch. The cable run that allows this also gives you space to thread your headphone cable -- it's very nicely thought-out.
The solar panels charge up the internal battery, which supplies the power. The bag also ships with a mains charger for the internal battery, so you can keep everything going on a dull and rainy day.
The days I tried the bag out, it was sunny and bright and there was no problem getting my phone to charge. One advantage of such a bag is that you can leave it by a window or in a sunny patch while you work.
Voltaic Systems claims that in direct sunlight the bag will recharge an average mobile phone in four to six hours. On a dull day it will take longer, and this is perhaps the biggest issue with such technologies. If it's a drizzly winter's day, you're not going to have much fun with it -- but then again, you're not going to be out and about with a backpack. In the middle of summer, this bag is perfect for a day on the beach with your MP3 player, or a short hike with a digital camera and GPS unit.
Solar power isn't new, of course, but until now it hasn't been efficient enough to produce the right amount of power on a small enough surface area. The old solar panels would use the sun to heat water, which would then drive turbines. This was inefficient and required huge areas to produce a good amount of power.
The newer technology, photovoltaic cells, uses a different effect -- when light in the form of a photon hits silicon, the silicon gives off an electron. Place the silicon in layers, and you can create an electrical charge. Over the years, photovoltaic cells have grown in power and are now a perfect size for garments. Flexibility and color are being added, although these reduce the power available. The Voltaic Systems bag's panels are not flexible, but are quite light.
The effect is like carrying a magazine in your backpack. The weight is barely noticeable.
QUIET START: Nearly a week after applications opened, agencies did not announce or promote the program, nor did they explain how it differed from other visitor visas Taiwan has launched a six-month “digital nomad visitor visa” program for foreign nationals from its list of visa-exempt countries who meet financial eligibility criteria and provide proof of work contracts. To apply, foreign nationals must either provide proof that they have obtained a digital nomad visa issued by another country or demonstrate earnings based on age brackets, the Bureau of Consular Affairs said. Applicants aged 20 to 29 must show they earned an annual salary of at least US$20,000 or its equivalent in one of the past two years, while those aged 30 or older must provide proof they earned US$40,000 in
SERIOUS ALLEGATIONS: The suspects formed spy networks and paramilitary groups to kill government officials during a possible Chinese invasion, prosecutors said Prosecutors have indicted seven retired military officers, members of the Rehabilitation Alliance Party, for allegedly obtaining funds from China, and forming paramilitary groups and assassination squads in Taiwan to collaborate with Chinese troops in a possible war. The suspects contravened the National Security Act (國家安全法) by taking photos and drawing maps of key radar stations, missile installations and the American Institute in Taiwan’s headquarters in Taipei, prosecutors said. They allegedly prepared to collaborate with China during a possible invasion of Taiwan, prosecutors said. Retired military officer Chu Hung-i (屈宏義), 62, a Republic of China Army Academy graduate, went to China
UNITY MESSAGE: Rather than focusing on what Trump said on the campaign trail about Taiwan, Taipei should be willing to engage with the US, Pompeo said Taiwan plays a key role in Washington’s model of deterrence against China, former US secretary of state Mike Pompeo said in a speech in Taipei yesterday. During US president-elect Donald Trump’s first term, “we had developed what we believe was a pretty effective model of deterrence against adversaries who wanted to undermine the set of rules and values that the people of Taiwan and the people of the US hold dear,” Pompeo said at a forum organized by the Formosa Republican Association. “Succeeding in continuing to build this model will not solely rest at the feet of president Trump and his team,
AIR DEFENSE: The Norwegian missile system has proved highly effective in Ukraine in its war against Russia, and the US has recommended it for Taiwan, an expert said The Norwegian Advanced Surface-to-Air Missile Systems (NASAMS) Taiwan ordered from the US would be installed in strategically important positions in Taipei and New Taipei City to guard the region, the Ministry of National Defense said in statement yesterday. The air defense system would be deployed in Taipei’s Songshan District (松山) and New Taipei City’s Tamsui District (淡水), the ministry said, adding that the systems could be delivered as soon as the end of this year. The US Defense Security Cooperation Agency has previously said that three NASAMS would be sold to Taiwan. The weapons are part of the 17th US arms sale to
