Researchers at LaserMotive have devised a way to beam lasers to power military bases and drones, possibly helping to save lives, since delivering fuel to battle zones can be a dangerous task in wartime.
Although still largely in the R&D stage, laser power beaming has many other potential uses, which include powering vehicles, replacing electric power wiring and transmission lines in difficult places, and even launching rockets into orbit.
The beam is about 8 inches wide as it leaves the transmitter - and then spreads wider as it travels. The beam emitter is located at a ground-based unit and operated by a person, who could control it from the same location or remotely from an entirely different place altogether.
The operator uses the machine to fire the laser beam at a photovoltaic collector located on an unmanned autonomous vehicle (UAV), small plane, or helicopter. The current range of the system is about a kilometer.
When the laser hits the photovoltaic device, the photons in the light beam are converted to electricity to fly the AUV.

Microsoft has posted an awesome new concept video with some ubercool new interfaces that could be here in five to ten years, estimates Kurt DelBene, President, Microsoft Office Division.
That sounds a bit conservative. "All of the ideas in the video are based on real technology," he said. "Some of the capabilities, such as speech recognition, real time collaboration, and data visualization, already exist today. Others are not yet available in specific products, but represent active research and development happening at Microsoft and other companies."
"Other companies" … hmm, some of the concepts look a bit like Nokia's visionary Morph concept tech (see the video at the bottom of this post and our 2010 news item).
Cloud computing is an Internet-based computing by which a range of resources such as servers, storage, and applications are delivered to company's devices and individual's computers through the internet.
Geo-targeted advertising has immense potential in covering consumers' based on their geographic location. It plays a vital role for companies to reach the particular audience
"The report gets across one very basic message: in the eyes of the leading experts on aerospace technology worldwide: harvesting solar power in space and transmitting it to earth is no longer science fiction," says author Howard Bloom in a companion announcement by the Space Development Steering Committee. "It is sound, current-technology-based science fact. And it is a green energy option we can't ignore.
Sodium-based batteries are particularly attractive: Sodium is a cheap, nontoxic, and abundant element that is uniformly distributed around the world and therefore would be ideal as a transport ion for rechargeable batteries.
And this technology is spreading. Immersive Labs, a company in Manhattan, has developed software for digital billboards using cameras to gauge the age range, sex and attention level of a passer-by. The smart signs, scheduled to roll out this month in Los Angeles, San Francisco and New York, deliver ads based on consumers' demographics. In other words, the system is smart enough to display, say, a Gillette ad to a male passer-by rather than an ad for Tampax.
Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand.
The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression.
This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells.
Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.
The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge. Opting for simple elegance, researchers from Cornell University, University of Chicago, and iRobot have bypassed traditional designs based around the human hand and fingers, and created a versatile gripper using everyday ground coffee and a latex party balloon.
Edgerton's major line of attack is the assertion that we falsely imagine that "technology" is the same as "innovation" and "invention." That the vast bulk of "technology" is the installed base. The old stuff.
One in a series of eleven Memoranda detailing the Distributed Adaptive Message Block Network, a proposed digital data communications system based on a distributed network concept. It introduces the system concept and outlines the requirements for and design considerations of such a system, especially in regard to implications for its use in the 1970s. In particular, the Memorandum is directed toward examining the use of redundancy as one means of building communications systems to withstand heavy enemy attacks.
ScienceDaily (May 22, 2010) - A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers at Linköping University and the Karolinska Institute in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells.
The new device developed by the research team achieved impressive practical results, capable of symmetrical bit writing with a resistance ratio between the two resistance states of over 500% and reproducible nonvolatile switching over 100,000 cycles.
