Rechargeable Light makes good use of your old glass bottles

bottle-lightRecycling has been quite the major theme for the past few years regardless of which particular country that you live in, and for good reason, too. After all, we are running out of non-renewable resources fast, and recycling is one way of maximizing the use of what we already have at the moment. Those old glass bottles that you have always wanted to do something with, but never really got around doing it? You can now put them to good use with the £10.00 Rechargeable Light.

Yes sir, the Rechargeable Light will be able to transform just about any old and unwanted glass bottle into a lamp, which could also prove to be romantic in nature. Specially shaped to resemble that of a cork, there is an extremely bright LED which will recharge itself via USB. You can use vintage drinks bottles to churn out interesting looking lights, or even create your very own cozy and improvised table feature. Heck, the Rechargeable Light would also be useful when outdoors, since candles stuck in an old wine bottle can get blown out by the wind. A 1 hour charge time would result in up to 2.5 hours of lighted time.

Which Of Your Gadgets Has The Most Impressive Battery Life?

Which Of Your Gadgets Has The Most Impressive Battery Life?

For 4.5 years I used a 15" macbook pro from mid-2008. It had changeable batteries so twice I went to Apple and convinced them to give me a new one for free. The three batteries I used in that machine were very different. The first one was a champ. It would last for six hours at its peak. It degraded slowly and predictably over time. It was reliable. But then, after two blissful years, it started throwing out Service Battery alerts.

EcoXPower charges a smartphone, bicycle headlight and tail light with pedal power

EcoXPower charges a smartphone, bicycle headlight and tail light with pedal power

Bicycle rigs for charging cellphones have lit up our radar before, but now the EcoXPower is being billed as the first device of its kind that can simultaneously juice up LED lights and a smartphone with the power of your pedaling. Packing a headlamp, a red tail light and a lithium-ion rechargeable battery, the contraption attaches to a bike’s front wheel hub with the help of a universal mount. When clamped on, the apparatus’ clutch engages between the velocipede’s spokes so it can generate electricity. A USB adapter cable runs up the two-wheeler’s fork to a water-resistant, touchscreen-friendly case that can house iPhones, Android handsets and “all major GPS devices” perched atop the handlebars. Cyclists yearning to charge their electronics with the dynamo can pick one up for $99.99. Roll past the break for the full press release.

Korean carbon-coated lithium-ion battery could cut recharge times down to minutes

Korean, carboncoated lithiumion battery could cut recharge times down to minutes

Anyone who’s had to recharge an EV — or, for that matter, any mobile device with a very big battery — knows the pain of waiting for hours while a lithium-ion pack tops up. South Korea’s Ulsan National Institute of Science and Technology has developed a conduction technique that could cut that charging time down to less than a minute. By dousing the nanoparticle materials of the battery in a graphite solution that’s then carbonized, the researchers make a web of conductors that all start charging at once; current batteries have to charge towards the center slowly, like a not-very-edible Tootsie Pop. The immediate goal is to develop a secondary battery for an EV that could provide extra mileage in a matter of seconds. Here’s hoping that the Ulsan team’s fast-charging battery is more viable than others and spreads to just about everything — we’d love to have EVs and laptops alike that power up in as much time as it takes to fill a traditional car at the pump.
