Hasta La Gadget!

Is there anything lasers can’t do? We only ask because they seem to be improving everything from microphones to railroads, and now researchers from Purdue University have leveraged the power of light to better manufacture solar cells. Using an ultrashort (as in quadrillionths of a second) pulse laser to more precisely scribe the microchannels connecting thin-film solar cells — as compared to current mechanical stylus methods — the Boilermakers were able to improve energy transfer efficiency between cells and significantly reduce manufacturing time. Having demonstrated the process works, research continues to better understand and prepare it for use by manufacturers — sooner rather than later, we hope.

Purdue researchers make solar cell manufacturing cheaper, more efficient with lasers originally appeared on Engadget on Fri, 11 Mar 2011 07:17:00 EDT. Please see our terms for use of feeds.

Though well on its way to joining the Dodo, one of the internal combustion engine’s advantages over its plug-in competition is refuel time — it only takes a few minutes to gas up, but you’re talking hours for an EV to top off its batteries via a standard 220 / 240-volt socket. This fact is not lost on Nissan, as it just revealed plans to offer a higher-rate charger in its 2012 Leaf — the current model’s 3.3kW charger needs eight hours to power up — in order to better compete with the Ford Focus Electric’s three to four hour charge time courtesy of its 6.6kW. And all you early adopters won’t be “orphaned,” as 2011 model Leafs can be retrofitted with the new electrics — no word if Daddy Warbucks will be footing the bill.

Wirelessly-powered TVs are nice, and transparent displays are cool and all, but what about an ambient light-powered transparent LCD? Well, that’s nothing short of awesome. Samsung showed off just such a device at CeBIT 2011 last week — a prototype 46-inch display with 1920 x 1080 resolution and ten-finger touchscreen capability. We aren’t sure what kind of black magic Sammy put in this thing, but it’s an incredible feat of engineering to make such a large display — and its accompanying solar cells — efficient enough to run exclusively off the juice it pulls from surrounding light sources. No word on how the photon-powered LCD compares to existing HD monitors in terms of brightness, refresh rates, or color reproduction, but a muted picture is a small price to pay for cutting the electrical cord forever.

So, you’ve got your government-issued solar panels and you bought a plug-in EV, but being both a budget-minded and green-conscious geek, you’re concerned that your home’s power generation and consumption isn’t exactly optimal. Put your worries aside, because Sharp has created the Intelligent Power Conditioner (IPC) to max out the electrical efficiency of your abode while working in conjunction with public utilities. It operates by temporarily storing the unused solar-generated juice from the daytime — using both the system’s batteries and the cells in your shiny new EV — to deliver a steady stream of electrons at night. In tests with a Mitsubishi i-MiEV, the system was able to use the EV to supply 8kW of power to a home, and doled out enough electricity (4kWh) to recharge the car in a scant 30 minutes. The IPC is still in the development phase, but Sharp is looking to make it commercially available “in the near future” — which means the finishing touches on your ultimate eco-house will have to wait.

Sharp’s Intelligent Power Conditioner works with EVs to make your house a lean, mean, solar-powered machine originally appeared on Engadget on Wed, 23 Feb 2011 13:13:00 EDT. Please see our terms for use of feeds.

Rugged? Check. Built-in flashlight? Nod. Solar panel on the rear? Yep. Android 2.2? For sure. All of the essentials (and then a few extras) have been tossed onto the Umeox Apollo smartphone, shown off for the first time today at Mobile World Congress in Barcelona. It’s hardly a high-end device — in fact, at just $100 off-contract, it’s bound to be one of the less-capable Froyo handsets on the market. But considering that this is positioned to put Android into the hands of those who aren’t exactly champing at the bit to spend a month’s wages on a phone, we’d say it’s a huge step in the right direction. When asking about specifications, we were told to expect a MediaTek processor, microSD card slot, rear-facing camera and a SIM card slot. The unit on display was a non-working mockup, with an on-site representative noting that shipments should begin to Europe, Latin America and India this May (with other nations to follow). The device felt satisfactorily solid, but unfortunately, no technical details were available regarding the solar panel on the rear.

In related news, the company was also showcasing a couple of other innovations: a new solar cell microchip and its first solar cell. Prior to this week, Intivation only sold the microprocessors, forcing partners to go and find their own panel supplier. Now, it’s entering another business with the Sunboost3 all-in-one solar module, and if it’s hopes and dreams come true, you’ll start seeing these on a slew of upcoming handsets. Hit the PDFs below for more of the nitty-gritty, and peek the Apollo mockup in the gallery below.
