HP has ominous intentions for budget gamers--and that's a great thing. Following the launch of last year's Omen gaming laptop, Starting July 10, HP is expanding the line to include several new gaming laptops that vary in size and price, including a 15.6-inch and a 17.3-inch notebook that start at $899 and $979 respectively. The new strategy allows the company to reach gamers at every budget, without sacrificing too much power or quality.

I had the opportunity to get up close and personal with both laptops during a recent press event, and I've got to say that HP might be on to something with its new approach.Outside of the obvious size difference, the new Omen laptops are virtually identical. In the interest of sparing shopper's wallets, HP swathed both devices in a faux carbon fiber, dubbed shadow mesh. The material is smooth and cool to the touch and provides a solid grip. Instead of the typical HP logo, these Omens are branded with a shiny red Voodoo logo -- a callback to VoodooPC, the gaming PC maker HP purchased back in 2006.

The notebooks' interior serves up more shadow mesh accentuated by a dragon-red backlit keyboard. HP kept a version of the 2014 Omen's hinges for this new crop of the devices. However, they're a little thick for my taste and lack the sweet blue tinge that made them look like they'd been kissed by hellfire.

The 15.6-inch Omen has a starting weight of 4.6 pounds with a thickness of 0.96 inches. That's on a par with the Acer Aspire V15 Nitro Black Edition (5.1 pounds, 15.4 x 10.3 x 0.9-inches). The 17.3-inch version weighs 6.3 pounds and is 1.17 inches thick, which puts it in distance of the Acer Predator 17 (7.5 pounds, 15.4 x 11.8 x 1.5 inches) or the Gigabyte P37X (6.7 pounds, 16.4 x 11.2 x 0.88 inches).Both iterations of the Omen are available in full HD (1920 x 1080) or a 4K (3840 x 2160) IPS display. The 4K versions I encountered appeared bright with crisp detail and vivid color. A slow pan of a forest of pine trees allowed me to enjoy the sun-dappled ground and dark green foliage.

HP is flaunting its recent partnership with Bang & Olufsen, adding the specially-tuned speakers to both systems and augmenting it with its own Audio Boost technology. Unfortunately, I didn't have the opportunity to give the speakers a test listen, but I'm looking forward to the doing so when our review unit arrives. Since both Omens are sub-$1000 devices, you're not going to get the most powerful specs. However, what is packaged with the laptops should deliver solid multitasking capabilities and frame rates, allowing you to play most titles at medium or high settings.Each notebook will be outfitted with a quad-core Intel Core i7 processor with up to 16GB of RAM, a Nvidia GeForce GTX 965M graphics. Gamers will have several storage options to choose from including up to a 512GB PCIe SSD or 2TB for single storage or up to a 4TB hard drive with 128GB solid-state hybrid drive.

The Omen is designed to accommodate all your gaming needs, including supporting a 4K monitor. The laptops will feature a pair of USB 3.0 ports, a single USB 2.0 port, Ethernet, an SD reader and an HDMI 2.0 port. In terms of connectivity, the notebooks will have Bluetooth 4.1 and 802.11 a/c. Certain configurations of the Omen will be outfitted with an Intel RealSense camera that will allow for some novel ways of gaming and live streaming.

Battery Life
HP claims the Omen laptops will have 10 hours of battery life on certain models. Most gaming laptops fall short of their lofty battery claims, but maybe HP will prove us wrong on this one. The notebooks will also feature Fast Charge, which is supposed to recharge up to 90 percent of your battery in 90 minutes when the system is shut down. Gamers love having a powerful rig that can deliver high frame rates and crisp graphics. However, they might not always have the money for the top-of-the-line system. HP is hoping its sub-$1000 Omens can split the difference, delivering strong mid-level performance at a budget-friend price. Throw in a large amount of storage, an optional RealSense camera and a lovely 4K display and HP might have a winner on its hands. However, those looking for more oomph will have to hold out until this summer for the high-performance Omen X laptop.
HP has expanded its Omen gaming line with the announcement of a new Omen desktop and Omen display as well as the unveiling of two new Omen laptops. The laptops include a 15.6-inch unit and a 17.3-inch laptop. The smaller of the duo has full HD resolution and the larger has 4K IPS tech for enhanced visuals. Both models feature a Dragon Red backlit keyboard and dual fans to keep them running cool during extended gaming sessions.

Power comes for a 62W battery that is towards the front of the notebook. Gamers can choose NVIDIA mobile graphics up to the 965M and a variety of Intel Core i7 quad core processors from the 6th generation series. Integrated webcams include a Wide Vision HD Camera and an optional Intel RealSense Camera for 3D.Up to 16GB of RAM can be fitted and storage is up to a 512GB SSD or a 2TB HDD for single storage options. Gamers can choose both a 4TB HDD and a 128GB SSD on select models. Internal audio systems have tuning by Bang & Olufsen and HP Audio Boost tech for depth with dual speakers. The notebooks are fitted with HP Fast Charge and the battery is good for up to ten hours per charge on select models.

Those select models with long battery life won’t be top of the line and will need an SSD. The gaming desktops will land at HP.com and BestBuy on July 10. The 15.6-inch laptop will start at $899.99 and the 17.3-inch will start at $979.99. Like all gaming machines, you can count on the price growing quickly if you option the machines heavily. HP has been unveiling all sorts of new products of late and one of the coolest new products is its Jet Fusion 3D printer. HP also unveiled a new EliteBook notebook computer this month.Solar energy has evolved as a major alternative source of energy. Solar energy is increasingly being utilized as source of energy for street lighting, automobiles, house appliances and others. In recent times, solar power banks are gaining popularity in the consumer market, with the rise in use of electronic gadgets. Solar power banks serve as an energy storage device, which can be utilized when required to charge any of the USB-charged devices such as cameras, portable speakers, GoPros, MP3 players GPS systems.

Solar power banks require sunlight to charge, making it reliable in circumstances where electrical supply or charger is not available. Most of the solar power banks available today can be charged alternatively via computer using USB. Considering solar as an environmental friendly technology, demand for solar power banks is expected to escalate in the coming years.

Solar power banks find wide range of applications such as charging of smartphones, laptop, tablets and other devices. The growth of smartphones, laptops and tablets market has generated the need for external energy storage devices for charging. The escalated use of internet with the availability of 3G and 4G services on smartphones and tablets has increased the consumption of battery at a faster rate, thus, driving the solar power bank market. Further, tourists or trekkers preferring to travel at distant places can rely on the solar power banks over the conventional power banks, as at times of emergencies solar power banks can be charged via sunlight. The rural areas in emerging markets such as Africa, Asia and Latin America pose good opportunities for solar power banks due to constraint of electricity supply in these regions.

Ltd., LG Chem Ltd, China BAK Battery, Inc., Mophie Inc., Microsoft Corporation, Panasonic Corporation, OnePlus, Sony Corporation, Samsung SDI Co. Ltd., UNU ELECTRONICS INC., Xiaomi Technology Co., Ltd, and Shenzhen Topband Co. LtdHave you seen the TV show? Aspiring entrepreneurs pitch their ideas to "shark” venture capitalists. Well, here’s how young Tesla Motors conceived, polished and pitched its big idea, as recounted by co-founder Marc Tarpenning in this under-exposed interview. TeslaMondo has mildly refined it for logical and temporal flow, and to delete the words "sort of,” which Tarpenning says almost as often as JB Straubel says "you know.”

This is a long post for a site that favors brevity, but this is the stuff of a good book. Maybe even a good movie. Certainly a good episode of Shark Tank, if TV allowed for a longer format. This ain’t no five-minute sales pitch.Context: Tesla’s co-founders, Tarpenning and Martin Eberhard, had just built and sold an ebook specialty company called NuvoMedia, and now had cars on the brain. They had zero automotive experience, but that would prove beneficial. Martin had this idea of — he’d wanted to buy an electric car, and it was right about the time the zero emissions mandate got re-written in Sacramento, so all the electric cars had ceased to exist. And they weren’t very good anyway. The EV1 was the only one that was kind of viable. And it was all-lease. And of course, GM took them back and crushed them.

So he was pissed off about that, and he said, ‘Why don’t we do this electric car thing? It can’t be that hard.’ And I thought: How are we ever going to make a car? Our experience with batteries in the consumer electronics world, with the ebooks, we knew batteries were getting better and better and better. They had gone really from nicad to nickel metal hydride, and then lithium-ion . . . so we were sure with some spreadsheet calculations that, in fact, you could put enough energy on a car to make it really compelling, I mean way better than any of these EV1s or anything else they’d ever imagined, and the rest of it is a computer science problem — because it’s really just computers synthesizing waveforms to make motors go — and a network problem because there’s lots of little computers required to do all of that, but, you know, that’s our world. Little computers that control stuff? Silicon Valley is really good at that.

If your goal is to reduce energy consumption — specifically oil consumption, but in any given resource — you want to use it as efficiently as possible, right? So you don’t want to pick something that consumes lots of it for no apparent reason, and hydrogen is uniquely bad . . . It’s a scam as far as I can tell, because the energy equation is terrible. It is just terrible.

The proponents always say, ‘Oh, hydrogen is the most abundant element in the universe.’ But it’s abundant out there in the universe, not here. We live on a planet where hydrogen is super reactive. It’s bound up into everything. It’s bound up into water, wood and everything else. They only way that you get hydrogen is that you have to pour energy in to make it. You have to break it free from the chemical bonds it’s bound up into.Electrolysis is the most common thing. You put electricity in water and it separates it, but you are pouring energy in order to make hydrogen, and then you have to compress it and that takes energy, and then you have to transport it to wherever you actually need it, which is very difficult because hydrogen is actually much harder to work with than gasoline or even natural gas — and natural gas is not that easy.And then you ultimately have to place it into a car where you’ll have a very high-pressure vessel which offers its own safety issues – and then, on top of that, you have to convert it back to electricity to make the car go because hydrogen-powered cars are really electric cars. They just have an extraordinarily bad battery.
