MoD unveils unmanned fighter jet 'of the future'

Wednesday, July 14, 2010

LONDON (AFP) – An unmanned jet capable of striking long-range targets has been dubbed the "combat aircraft of the future" by the Ministry of Defence.

The Taranis -- named after the Celtic god of thunder -- was unveiled at a ceremony at BAE Systems in Warton, Lancashire, on Monday. The £142.5 million prototype is the size of a light aircraft and has been equipped with stealth technology to make it virtually undetectable.

In a press release, the MoD described the Taranis as "a prototype unmanned combat aircraft of the future."

It is built to carry out intelligence, surveillance and reconnaissance missions while its crew stays safely on the ground and can control the aircraft from anywhere in the world.

The unmanned fighter jet can also carry bombs and missiles and, if the trials prove successful, the MoD said it should "ultimately be capable of striking targets at long range, even in another continent."

The current generation of propeller-driven drones -- such as the Predator and Reaper -- are capable of carrying missiles, but these unmanned planes can only be used in areas where the military has air dominance, such as Iraq and Afghanistan.

The first flight trials are due to start next year.

"Taranis is a truly trailblazing project," said Minister for International Security Strategy Gerald Howarth.

"The first of its kind in the UK, it reflects the best of our nation's advanced design and technology skills and is a leading programme on the global stage."

The Taranis was created by the MOD in partnership with BAE Systems, Rolls-Royce, QinetiQ and GE Aviation.

"Taranis has been three-and-a-half years in the making and is the product of more than a million man-hours," said Nigel Whitehead, group managing director of BAE Systems' Programmes and Support business.

"It represents a significant step forward in this country's fast-jet capability.

"This technology is key to sustaining a strong industrial base and to maintain the UK's leading position as a centre for engineering excellence and innovation."

A New Bloom for Algae

A DOE Roadmap Marks a Return to Research on a Source of Fuel That Was Once Thought Too Costly

This week the U.S. Department of Energy released a new roadmap for the development of algal biofuels. DOE researchers had dismissed this type of biofuel as too costly to be commercially successful in the mid-1990s following a nearly two-decade-long research project.The new roadmap was accompanied by the announcement of $24 million in new DOE funding for algal biofuels research.

That money is in addition to $140 million in algae funding from last year's Recovery Act.

"Biotechnology has come a long way" since the earlier project, says Valerie Sarisky-Reed of the Office of Energy Efficiency and Renewable Energy, one of the lead authors of the roadmap. "With a dedicated research and development program, we can bring the economics to a suitable place within a 10-year time frame," she says.

We chose to invest in it again because we felt we were within striking distance.The DOE originally considered algae as a means of making biofuels because some types of algae naturally produce large amounts of oil. The prolific organisms, if grown in ponds or closed bioreactors, could be used to produce more fuel per acre than other biofuels approaches, such as biochemically or thermochemically converting cellulosic biomass into fuel.

But the DOE program, which concluded in 1996, found that growing algae, and then harvesting and processing the oils, would only be cost-effective at high petroleum prices--between $59 and $186 a barrel. About that time, oil prices were less than $20 a barrel.

Current estimates of the required price of petroleum for algae to be competitive range widely, from $10 to $100 a barrel, Sarisky-Reed says. Some estimates are even higher. Conventional approaches are only competitive when oil prices are as high as $400 a barrel, says David Berry, a partner at Flagship Ventures, based in Cambridge, MA.

Top 10 Tech Inventions Shaping 2010

3M/Littmann Electronic Stethoscope Model 3200 With Zargis Cardioscan

The stethoscope hasn’t undergone many significant breakthroughs until now. 3M’s new stethoscope listens to a patient’s heartbeat, captures the sound for later playback, lets you transmit sounds real-time to your PC, which can then be further analyzed, attached to medical records, or reviewed online with colleagues.The sound-amplifying 3M Littmann Electronic Stethoscope 3200 will not only be able to catch dangerous murmurs and heart defects but will also eliminate more than eight million unnecessary echocardiograms and cardiologist visits a year, saving some $9.4 billion.

XM25 Counter Defilade Target Engagement System (i.e. The Smart Bullet)

The XM25, currently under development for the U.S. military by Alliant Tech systems, allows soldiers to measure the distance to a target using a laser range finder, dials in exactly where the bullet should explode (over or past walls, the corner of buildings) at precise distances. At a cost of $30/round, the bullets are equipped with microchips capable of registering distance according to the number of times they’ve rotated.

The Electric Eye

MIT researchers are developing a microchip that will enable a blind person to recognize faces and navigate a room without assistance, helping the blind to regain partial eyesight. The chip, which is encased in titanium to prevent water damage, will be implanted onto a patient’s eyeball. Users are required to wear special glasses fitted with a small camera that transmits images to the titanium-encased chip, which fires an electrode array under the retina that stimulates the optic nerve. The glasses will help to power the coils surrounding the eyeball.

AT&T Will Be Able to Handle the iPhone

Monday, June 21, 2010

Pity AT&T and their troubled data network. While previous iPhones' data usage was largely confined to static webpages, simple apps and maybe the occasional song streamed through Pandora, the just-announced iPhone 4's (available June 24) hunger can best be described in one word: video. In other words: If you thought the iPhone was a data-hog before, you ain't seen nothin' yet.

The ability to capture 720p HD video and edit it right on the phone using the new mobile version of Apple's iMovie video editing software. Users will then be able to send their massive video files into the ether over the AT&T network.

-A Netflix app that can stream entire movies over either Wi-Fi or AT&T's network.

-A new operating system (iOS4 it will be called) that will allow users to keep audio-streaming apps such as Pandora running in the background while they complete other tasks. This should dramatically increase the usage of these data-heavy programs.

If the previous iPhones' comparably puny data demands were enough to bring AT&T's network to a standstill in some cities, what's going to happen when customers get their hands on these new features?

Of course, AT&T anticipated this and, just last week, announced the death of their unlimited iPhone data plans. But while this move may stem some of the bleeding, millions of iPhone users will be allowed to hold onto their grandfathered-in unlimited data plans, meaning it could be years before these caps have a noticeable impact on the network load.

At least their new "FaceTime" video calling feature (which takes advantage of the new front-facing camera) is currently Wi-Fi-only (a disappointing reality, considering the new Sprint EVO 4G does video-conferencing over 3G).

So how will AT&T handle this new data load? Other than vague comments by Steve Jobs at the recent D8 conference that it will all get better soon, we honestly have no idea. Even ambitious expansion of cellular network capacity is unlikely to fully tackle the problem—especially when one considers that this great new device will likely cause millions of new users to hop on AT&T's network. AT&T: You have our pity.

Latest Humanoid Robots Uncanny and Creepy

An oft-cited theory in robotics, the uncanny valley, refers to that point along the chart of robot–human likeness where a robot looks and acts nearly—but not exactly—like a human.

This subtle imperfection, the theory states, causes people's feelings toward robots to veer from fondness to revulsion.” –cited in a post by Popular Mechanic’s The Truth About Robots and the Uncanny Valley: Analysis.

Thought it was interesting to know where the humans have now explored the uncanny side of robotics, though it was a little bit creepy to tell that “it wasn’t movie-like” but apparently there are possibilities that in the near future we’ll have a humanoid counterparts. In this post we listed the latest humanoid robots that have been developed. Demo and development videos after the break, then don’t be scared.
