Welcome to the World, Drone-Killing Laser Cannon

As reported by WiredHANG ON TO your drone. Boeing’s developed a laser cannon specifically designed to turn unmanned aircraft into flaming wreckage.

The aerospace company’s new weapon system, which it publicly tested this week in a New Mexico industrial park, isn’t quite as cool as what you see in Star Wars—there’s no flying beams of light, no “pew! pew!” sound effects. But it is nonetheless a working laser cannon, and it will take your drone down.
People keep flying their drones where they shouldn’t. In airport flight paths. Above wildfires. Onto the White House lawn. Luckily, there haven’t been any really bad incidents—that is, no one has been killed by a civilian quadcopter or plane, yet.


But governments and militaries around the world are terrified by the prospect of drones carrying explosives or chemical weapons (and now, pornography) into places where they shouldn’t.
There are lots of theories on the best way to deal with the drone threat. An Idaho company has developed special anti-drone shotgun shells. Some agencies are working on jamming technology to block communication from the operator to the aircraft. Firefighters in New York kept it simple, aiming their hose at a pesky drone hovering near a house fire.
Forget all that. Boeing thinks the best way to kill a drone is to zap it with a precision laser, burn a hole in it, and bring it down. So it created a weapon system to do just that—and the result could someday be installed everywhere from LaGuardia to the Pentagon.
Wednesday morning, the company showed off its Compact Laser Weapon System for media in Albuquerque, New Mexico. It’s a much smaller, significantly more portable version of the High Energy Laser Mobile Demonstrator (HEL MD) Boeing demonstrated last year. This setup looks like an overgrown camera, swiveling around on a tripod.
In the demo, Boeing used the laser to burn holes in a stationary, composite UAV shell, to show how quickly it can compromise an aircraft. Two seconds at full power and the target was aflame. Other than numerous safety warnings to ensure no one was blinded by the two-kilowatt infrared laser, there was no fanfare. No explosions, no visible beam. It’s more like burning ants with a really, really expensive magnifying glass than obliterating Alderaan.
Instead of a massive laser mounted on a dedicated truck, the compact system is small enough to fit in four suitcase-sized boxes and can be set up by a pair of soldiers or technicians in just a few minutes. At the moment, it’s aimed primarily at driving drones away from sensitive areas.


The new system is more scalpel than sledgehammer. Its laser, and, especially, the off-the-shelf gimbal (a fancy motor that can aim the laser and camera in any direction) it’s mounted on, make it precise enough to target different parts of a UAV. Want to zap the tail so it crashes and then you can go retrieve the mostly intact drone and see who is trying to spy on you? Can do. Think it’s carrying explosives and you want to completely destroy it? No problem. Boeing wouldn’t get specific on its range, but company reps suggested that if you can see a target, even with binoculars, you can kill it.
Depending on the target’s speed and distance, Boeing’s weapon can fire its laser within an inch or two of what it wants to hit. Because the laser moves at the speed of light, it’s easier to be precise—there’s no need to lead the target. The speed of the gimbal is the primary limitation on the targeting front.
The laser is controlled with a standard Xbox 360 controller (“If it breaks, just head to the barracks to get a replacement!”) and a laptop with custom targeting software. Once in range, the system can take over from the human operator and control targeting and tracking automatically. Though current prototypes are meant to be used from static positions, the new weapon could be used on a moving vehicle or ship with minimal upgrades.
“This represents a low-cost way to deal with the threat,” said David DeYoung, director of Boeing Laser & Electro-Optical Systems. Boeing wouldn’t reveal a total price of the system, but says it’s a one-time purchase. Once you’ve got the system, the only cost is electricity. The company expects the system to run for “years” with basic maintenance (the gimbal is the only moving part) and near-zero ongoing costs since there’s no traditional ammunition.
The necessary electricity can come from standard 220 volt outlet, a generator on a military vehicle, or a battery pack for ultimate portability. Boeing has several battery solutions depending on situational need, but all should give enough juice for at least a few shots.
The company hopes to have the Star Wars-inspired weapon ready for market in a year or two, with many refinements and developments to come over the next few years. But don’t expect lasers to replace traditional armaments like Raytheon’s Patriot missile defense system and Israel’s Iron Dome. “There will be times where it makes sense to use a missile and there will be times where it makes sense to use a laser,” says DeYoung.
As with any military weapon, Boeing would need to work through export control regulations before selling to foreign governments. It’s also not clear whether civilian agencies running prisons and airports could deploy the system under current regulations, or even what regulations might apply to something like this.
Perhaps the biggest disappointment is that the laser doesn’t make any noise. A Boeing rep did say the company’s planning to add a number of sound effects to the control station, to help multi-tasking operators keep an eye on what’s going on when it’s in an automated tracking mode. Hopefully they’ll hire Industrial Light and Magic to appease disappointed laser-lovers.

There’s a Massive Battle Brewing Over the Future Of Wi-Fi

As reported by TimeVerizon and T-Mobile are planning to use Wi-Fi networks to broadcast their cellular signals — a move that could clog up the airwaves and lead to fierce competition, according to a report in The Wall Street Journal.
The two wireless carriers are set to introduce LTE-U, an iteration of the LTE cellular standard that will switch to the least congested channel, which includes Wi-Fi frequencies. It eases the load on the carriers’ networks, but it could also burden Wi-Fi networks, reducing speed and quality. It’s also an inexpensive way to transmit signals, since Wi-Fi uses free, unlicensed airwaves, as detailed in a recent Fortune story.
This should worry companies such as Google, Cablevision, and Republic Wireless, who use Wi-Fi either as hotspots for users or to offer wireless services of their own. According to the Journal, Google officials recently wrote a letter to the Federal Communications Commission, remarking that LTE-U was “particularly worrisome” because wireless carriers “may view some Wi-Fi providers, such as cable companies offering Wi-Fi hotspots to their customers, as competitors.”
Verizon and T-Mobile are adamant their technology won’t degrade Wi-Fi connections. “Every test that we’ve done shows that LTE-U is as good of a neighbor to Wi-Fi as Wi-Fi is to itself,” Patrick Welsh, director of federal government affairs at Verizon, told the newspaper.
Wi-Fi usage is already growing rapidly among mobile users, and this development could lead to network congestion. In a report last year by Mobidia Technology, those on Android phones consumed 6.8GB and those with iPhones consumed 8.9GB of Wi-Fi data from July to September, 2014. In comparison, 1.8GB of cellular data were used by cellular subscribers over the same period.

Should Police Be Able to Take Control of Self-Driving Cars?

As reported by SlateA few lines in a seemingly routine RAND Corp. report on the future of technology and law enforcement last week raised a provocative question: Should police have the power to take control of a self-driving car?
Here’s a hypothetical scenario from the report’s introduction:
The police officer directing traffic in the intersection could see the car barreling toward him and the occupant looking down at his smartphone. Officer Rodriguez gestured for the car to stop, and the self-driving vehicle rolled to a halt behind the crosswalk.
That seems like a pretty plausible interaction. Human drivers are required to pull over when a police officer gestures for them to do so. It’s reasonable to expect that self-driving cars would do the same. To look at it another way: Self-driving cars are programmed to stop at red lights and stop signs. Surely they should also be programmed to stop when a police officer flags them down. It is, after all, the law.
It’s clear, then, that police officers should have some power over the movements of self-driving cars. What’s less clear is where to draw the line. If a police officer can command a self-driving car to pull over for his own safety and that of others on the road, can he do the same if he suspects the passenger of a crime? And what if the passenger doesn’t want the car to stop—can she override the command, or does the police officer have ultimate control?
A brief section on connected and autonomous cars later in the report outlined other ways police could take advantage of the technology:
Imagine a law enforcement officer interacting with a vehicle that has sensors connected to the Internet. With the appropriate judicial clearances, an officer could ask the vehicle to identify its occupants and location histories. … Or, if the vehicle is unmanned but capable of autonomous movement and in an undesirable location (for example, parked illegally or in the immediate vicinity of an emergency), an officer could direct the vehicle to move to a new location (with the vehicle’s intelligent agents recognizing “officer” and “directions to move”) and automatically notify its owner and occupants.
Again, that all sounds benign enough, in itself. But if police have the capability to glean personal information from a sensor-equipped car, who will ensure that they have the appropriate clearances before doing so? And what if police want to direct the movements of a self-driving car when it does have humans inside?
The RAND study, commissioned by the National Institute of Justice, did not attempt to answer those questions directly. Rather, it asked a panel of 16 experts in criminal justice and technology to identify imminent changes in information technology that might have an impact on law enforcement policies and procedures. What control police should have over self-driving cars was just one of numerous questions raised in the 32-page report, and it merited only a few paragraphs of discussion. Still, it’s clearly an issue that is on the radar of law enforcement already. And it’s likely to become more urgent in the coming years as self-driving cars attempt to cross the bridge from research project to commercial reality.
The report acknowledged that “the dark side to all of the emerging access and interconnectivity is the risk to the public’s civil rights, privacy rights, and security.” It added, “One can readily imagine abuses that might occur if, for example, capabilities to control automated vehicles and the disclosure of detailed personal information about their occupants were not tightly controlled and secured.”
You don’t even have to imagine it, really: Hackers are already taking control of cars via their onboard computers even without a built-in mechanism designed to allow it.
I asked the report’s lead author, RAND Corp. operations researcher John S. Hollywood, whether he got the sense that the law enforcement representatives on the panel were eager to push for law enforcement control of Internet-connected and self-driving cars. He told me they weren’t. Rather, in ranking their priorities, they put “developing policies and procedures for self-driving unmanned and automated vehicles” at the top of the list. Among the policy and procedure questions they may ponder: Will they need a warrant before accessing a self-driving car’s data? John Frank Weaver discussed that issue in more depth in a recent Future Tense post.
The panelists’ lowest-ranked priority: “Develop an interface for officers to directly take control of unmanned vehicles.”
While the ranking is reassuring, it’s a little unnerving that such an interface would register as a priority at all. It shouldn’t come as a surprise, however. Given how hard the federal government and its spy agencies have pushed for backdoor access to our social networks and email servers, there’s little doubt they’ll want the same with our cars.

These Electric Powered Surfboards can Surf on Flat Water

As reported by Business InsiderIf you want to surf on flat water, you either need to be towed by a boat, or have a built-in motor on your board. It used to be that the latter option was impossible, but now that batteries and electric motors are smaller than ever before, surf startups all over the globe are building self-propelled boards that you can ride anywhere — not just the ocean.

onean electric jet board 2 640x427 cThe latest entry into this burgeoning category comes from Onean Electric Jet Surfboards. The company has recently unveiled a pair of boards equipped with powerful electric engines — effectively allowing you to surf without waves.
The Carver and the Manta, as they’re called, both sport onboard 4400-Watt brushless motors under your feet. The boards are sandwich style with a CNC and EPS shaped core, and while their top speed is still being tested, they look pretty damn quick in the video below. The axial water pump powered by the motor is controlled with a wireless remote. The motor is silent and, since it’s electric, both of the company’s boards are safe for use in protected areas.
With more of an elongated oval shape and a tapered nose, the Carver is made to slalom, or “carve” up the water. The top speed is still being tested, but the battery can handle about 20 minutes at full thrust. It has two foot straps to keep you safely on-board.
The Manta is a little heavier and has a square shape that makes it more stable. It’s designed for smooth cruising at lower speeds, topping out at 8 kilometers an hour. It’ll cruise for two hours before the battery dies, which makes it perfect for exploring. In either case, the battery takes about two hours to charge, so you can charge it in the morning before you head out to the water. Onean does offer extra batteries for $1,300 each.

Tesla Motors Inc Model S Gets 450 Miles on a Single Charge [Video]

As reported by Green Car ReportsA pair of Danish drivers claim to have set a new record for Tesla Model S electric-car range.

Over the weekend, the pair covered 728.7 kilometers (452.8 miles), after a marathon drive beginning and ending at the Supercharger DC fast-charging site in Rødekro, Denmark.

The drivers claim to have used 77.5 kilowatt-hours of energy to cover that distance, meaning there was potentially still some range left in their 85-kWh Model S P85D at the end.

The trip involved 18 hours and 40 minutes of driving, plus one hour of rest stops.
Achieving the remarkable range figure required some drastic measures that average drivers probably wouldn't tolerate.

Average speed was just 39 kph (24.2 mph). Signs were taped to the back of the car advising other drivers of its slow speed.


As seen in a video of the drive posted on YouTube, the air conditioning was also used sparingly.
Apparently that's what it takes to achieve a range that significantly exceeds the EPA-rated combined 253 miles of the P85D.

With its focus on performance, the P85D has the lowest range of any 85-kWh Model S.
The rear-wheel drive Model S 85 is rated at 265 miles, while the all-wheel drive 85D is rated at 270 miles.


Tesla is in the midst of introducing a 90-kWh battery-pack option, which should bump range up somewhat over corresponding 85-kWh models.

The company expects a 6 to 7 percent increase, roughly equivalent to the increase in energy capacity of the new pack.

Tesla CEO Elon Musk has also said that a Model S 90D will achieve close to 300 miles of range in highway driving, when driven at a steady 65 mph.

The final battery-pack option in the Model S range is the smaller 70-kWh unit, which has now replaced the previous 65-kWh base pack.

The 70-kWh pack can provide 230 miles of range in the rear-wheel drive Model S 70, and 240 miles in the all-wheel drive Model S 70D.

The World’s First Fully Solar-Powered Airport

As reported by the TelegraphIndia has unveiled the first airport in the world to operate completely on solar energy.

A solar power plant with 46,150 solar panels has been installed across 45 acres of land near the cargo area of Cochin International Airport (CIAL). It supplies the airport with 50,000 to 60,000 units of electricity per day, making the airport “absolutely power neutral”, according to a statement by CIAL.
India's leading airport in sustainability had already been using solar energy from two smaller power plants installed in 2013. But the latest addition brings its solar energy capacity up to 12 megawatts (MW) of power per day, a sufficient amount to run all of the airport’s daily functions.

The new plant is expected to generate 18 million units of solar power annually, an amount that could charge around 10,000 homes in the country for one year. The sustainable project is expected to offset carbon emissions by more than 3 lakh (300,000) metric tons over the next 25 years, which is said to be the equivalent of planting three million trees or not driving for 750 miles, according to the airport.
Cochin International is the busiest and largest airport in the state of Kerala and the third busiest in India, according to international passenger traffic, having received more than 3,750,000 passengers between 2013 and 2014.
Its latest development is one of several ‘green’ initiatives currently in place or being planned at airports globally in the future.
Plans for Mexico City’s new international airport, which aims to be world’s most sustainable airport, were revealed last year. The Mexican capital's new airport will be designed by Norman Foster, the British architect responsible for the Gherkin (30 St Mary Axe) and the dome of Berlin’s Reichstag building. The new hub, expected to be completed by 2018, will use minimal energy and offer an efficient passenger experience with shorter walking distances.

Heathrow’s Terminal 2, which opened last year, was the first airport terminal in the world to be certified by BREAM (Building Research Establishment Environmental Assessment Methodology), the world’s longest established building sustainability rating system.
T2’s eco-friendly features include “skylights and 10 metre-high, floor-to-ceiling windows that maximise the natural light” and “sophisticated lighting control systems that keep energy use down by switching off the LED lights when parts of the building are not in use”. The terminal’s close proximity to the runways also helps cut carbon emission by reducing aircraft taxiing times.
Last year, Denver International Airport in the US installed its fourth solar power array which can produce up to 2MW of electricity per year. It reduces around 2,200 metric tons of carbon emissions annually, which is said to be enough to supply energy to 500 homes in Denver for a year.

Sustainability has been developed for several years at airports in North America, including Chicago O’Hare International which has been a founding figure in airport sustainability since 2003 when it created the Sustainable Design Manual to establish “greener airport development” within the industry. The manual was updated as the Sustainable Airport Manual in 2009 and has since been used as a standard for sustainability design by airports across the country.
In 2006, Terminal A at Boston’s Logan International Airport installed several sustainable features, including heat-reflecting roofs and windows, self-dimming lights and a storm water filtration system, making it the first airport terminal in the US to receive LEED (Leadership in Energy and Environmental Design) certification from the Green Building Council.

Trudeau International in Montreal has been making ground-breaking developments in sustainability since 2004, including an underground car park heated by hot water and automated blinds in the airport jetties that respond to natural light, helping to save on heating and air conditioning costs.
Arizona’s Phoenix Sky Harbor International airport was given a 'gold rating' by LEED last year for its PHX Sky Train, an electric, automated transport system that reduced the airport’s carbon footprint by nearly 6,000 tons a year.

Hydrogen Fuel Cell Integrated into iPhone 6 Powers it for a Week

As reported by GeekFuel cells have been promising to solve the rechargeable battery problem for years now. Rather than relying on a battery that takes hours to recharge once drained, you instead have hydrogen fuel cells that can be instantly topped up for hours more use. We haven’t seen such a fuel cell system make it into a mass-market device just yet, but a British company has now managed to hook one up to a modern smartphone.

The company in question is called Intelligent Energy. What they’ve managed to do is add a very slim hydrogen fuel cell to an iPhone 6. It doesn’t replace the need for a rechargeable battery, instead complementing it. However, the combination means that the iPhone can run for an entire week without need of a recharge.
Intelligent Systems is thought to be working closely with Apple on the prototype and importantly they’ve managed to integrate the fuel cell without needing to modify the iPhone. The only difference users will see is the back of the iPhone covered in vents. This is necessary to allow heat and water vapor to escape, but you’ll never notice it happening.
The fuel cell works by creating electricity from hydrogen and oxygen with the waste products being water vapor and heat. That electricity is then used to keep the iPhone battery topped up and powering the phone. When the fuel cell runs out of hydrogen it can be topped up with a cartridge.
Typically with fuel cell news it ends with “now they just have to make it small enough” or “they just need to find a commercial partner.” However, in the case of Intelligent Energy, the fuel cell is already small enough and Apple is thought to be on board. All they need to do now is design a disposable cartridge for the refills and decide on pricing.
