Hitting the Books: What the wearables of tomorrow might look like
Smaller, more powerful electronics are leading the current wearable revolution. In The Skeptic's Guide the the Future, Dr. Steven Novella looks at what comes next.
California could ban gas-powered generators and mowers by 2024
Some leaf blowers and pressure washers will be affected too.
Misusing Ford’s 2021 F-150 pickup generator
The 2021 Ford F-150 pickup has a generator that can power your tools, and even a small scale construction site. So of course, we made pizza bagels with it.
Daimler and Volvo team up to make fuel cells for trucks and generators
Daimler and Volvo are forming a joint venture to create hydrogen fuel cells for heavy-duty trucks and even power generators.
All Ford vehicles will have built-in 4G LTE by 2020
Ford's vision for the future is electric, connectivity and assisted driving. For the Blue Oval company, that means by 2020 its entire lineup will have 4G LTE connectivity and offer Waze navigation by way of AppLink and Sync 3. The former means that all aspects of a vehicle can be updated over the air rather than just the Sync platform. The latter is a bid to make the road safer by decreasing distracted driving that's caused by fumbling with your phone while behind the wheel; all cars with Sync 3 can start using Waze next month. And after studying how people use their trucks, the F-150 will have an available bed-mounted generator for the folks who need to export power on the job-site -- an idea Chevy experimented with on its ZH2 concept truck for the military.
New magnetic field theory gets us closer to nuclear fusion
Researchers from the US Department of Energy (DoE) and Princeton University have developed a new theory on plasma that could help scientists figure out solar flares and fusion power. Most fusion research is focused on "magnetic confinement" reactors that use powerful magnets to fuse hydrogen plasma into helium. One of the biggest problems with that technique is that the plasma itself spawns new magnetic fields, which play havoc with the reactions.
Future medical wearables could be powered by body heat
Researchers at NC State think that they have developed a new way to harvest body heat and turn it into electricity. The team has developed a patch that's roughly a centimeter squared, that would attach to a person's bicep. The device would then be able to generate anything up to 20 Microwatts, a significant increase on previous technologies. It's not enough to power a smartwatch, but it's possible that it may be enough to juice a medical sensor, reducing the number of bulky cables a patient has to trail around them.
Siva Cycle Atom charges USB devices with a pedal-powered battery pack (video)
Bicycle-powered generators aren't new concepts by any stretch, but they frequently generate AC power and sometimes can't charge at all when the pedaling stops. Siva Cycle doesn't think either limitation is very helpful for powering a smartphone during the daily commute, so it's launching the Atom generator to keep the energy flowing smoothly. The rear-wheel unit puts out power regulated to match its USB port, and it includes a detachable 1,300mAh lithium polymer battery that can follow riders long after they've parked. Moreover, the Atom is unintrusive -- it slips on after releasing the rear wheel, and it's diminutive enough to minimize drag. As is often the case these days, the catch is getting the product to market. Siva Cycle wants to crowdfund $85,000 to make the Atom's November release target, and supporters will need to plunk down at least $85 to receive a generator, if its fundraising goes smoothly. When the company plans to donate one Atom to the needy for every ten it sells, however, the pledge is for a good cause -- and it might be the key to having a usable device charge after a bike ride home.
Urine-powered generator produces six hours of electricity per bathroom break
We've all heard the expression "haste makes waste," but how about waste making energy? At the fourth annual Maker Faire Africa in Lagos, Nigeria, a quartet of teenage girls ages 14 through 15 have created a urine-powered generator. This eco-friendly energy source cranks out six hours of electricity for every liter of human bodily fluid by separating the excretion's hydrogen with an electrolytic cell. While this method of human waste disposal seems promising, the device has the potential to be a pee-powered biobomb and will need more than its limited safety measures before you're able to pick one up at your local hardware store. However, if this can help us save a few bucks on our energy bill, then we need to introduce these girls to these guys posthaste.
Mitsumi exhibits micro-vibration power generator and batteryless RF switch (video)
This picture from Mitsumi's CEATEC booth may not seem to say much, but it's certainly showing the future. The silver cylinder at the top is actually a small power generating device that converts micro-vibrations into usable energy, so stick one of these on, say, a ventilation duct and you should just about get enough juice to power a calculator or even an LED. In fact, Mitsumi says these can be integrated into the RF sensor network of large air conditioning facilities, as an RF transmitter can run on very little power these days -- even less than a calculator. Alas, a company rep said this product won't be available until 2014. Speaking of RF, Mitsumi does have something even more awesome that will be launched sooner. You see that black stick on the left? Embedded inside it is a batteryless RF switch, and the way it works is that upon the release of the spring mechanism inside, a tiny bit of power is generated for the 2.4GHz RF transmission (ZigBee compatible), and whatever device is connected to the RF control outlet on the other end will receive the on or off signal. So yes, you basically get a switch that requires no wiring nor power (except for the receiving end)! Expect this to hit the shelves in March 2013. For now, we have a hands-on video after the break.
Insert Coin: The PowerPot portable electric generator (video)
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Assuming you're not getting through the day with a bounty of fuel cell-powered gadgets, you've probably been in a situation where you needed power and it was nowhere to be found. The PowerPot isn't the most practical solution for every scenario, but it's likely to come in handy at least once. The power-generating pot uses thermoelectric modules to convert temperature differences into a 5-, 10- or 15-watt regulated power stream, sufficient for juicing up USB devices like smartphones, GPS devices and LED lamps. The most traditional method for creating this temperature difference is to put a pot of cold water over an open flame, but the device is adaptable to other configurations -- a pot of snow on a thermal spring, for example. Assuming you've taken the fire approach, you can also use the pot to boil water or cook food as you charge your gadgets. The inventor has created a functional prototype that features fire-proof components and looks quite polished, but now the team is turning to Kickstarter to advance the project to production. Your pledge could net you any of a variety of PowerPots, ranging from a 5-watt portable V flavor for $125 to the 15-watt XV for $500. You can also pre-order a 10-watt PowerPot X for $199. If you're feeling generous, there's also an option to donate a PowerPot to folks in developing nations who may not have the cash to spare, but are in need of a cost-effective solution for power generation. Jump past the break to see the PowerPot V in action, and hit up the source link to scroll through the available configs before making your pledge.
Inhabitat's Week in Green: Lighting superbike, kinetic energy generator and vibrating gloves
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. It's been an epic week for environmental news as Inhabitat reported that the East Coast battened its hatches against the force of Hurricane Irene, which has arrived in the wake of a 5.8 earthquake that shook the Eastern Seaboard from Virginia to New York. We compiled a series of tips to help our readers weather the storm, and we took a closer look at the six nuclear power plants that were shaken by the East Coast's unusual quake. We also showcased several incredible examples of high-tech architecture -- the recently crowned world's tallest LEED platinum building and the world's longest tunnel, which Russia recently announced would span the Bering Straight. Speaking of remarkable advancements in sustainable transportation, this week we took at look at what could be most powerful electric car on earth, and we brought you footage of the 200 mph Lighting superbike breaking a world land speed record. We also saw eco vehicles take off for greener horizons as Oliver VTOL unveiled an ultra-efficient airplane with 6 engines, a team of engineers in Africa constructed a DIY space shuttle in a local garden, and the flying ParaMoto Trike soared through the skies. On the topic of air travel, you may also want to check out our six tips for flying with small children (without Benadryl). It was a big week for wearable technology as well, as researchers unveiled a powerful kinetic energy generator that can fit in your sneakers. We also saw a vibrating glove that improves motor performance, a haptic glove that allows the blind to see with sonar, and a range of antenna-embedded clothing that offers a discreet form of hands-free communication. Finally, we heard Ashton Kutcher predict that wearable technology will be the next big wave, and we shared a glow-in-the-dark sequin gown that would make a choice piece of evening wear if this weekend's storm knocks the lights out.
Georgia Tech engineers pull energy out of atmospheric hat, go on electromagnetic scavenger hunt
Mankind's about to plunge into the depths of a wireless sensor-powering ether binge -- braincell annihilating vapors not included. Spearheaded by Georgia Institute of Technology's professor Manos Tentzeris and his engineering team, this ambient energy scavenging tech harnesses electromagnetic frequencies in the 100MHz - 15GHz range -- anything from your FM car radio to radar -- and converts it into a useable DC power source. So, it's free energy -- kind of. The cheap, self-powering paper or flexible polymer-based sensors are created using standard inkjet printers and Tentzeris' "unique in-house recipe" of circuit-building silver nanoparticles. Current testing hasn't yet yielded significant enough wattage to power your PS3 Slim, but it could soon via the help of supercapacitors and future solar cell integration. Imagine clothing embedded with health-monitoring biometric sensors, airport security run by something other than aloof TSA agents, or even spoilage-aware drink cartons -- milk that tells you when it's gone sour. The invisible radio band-charged possibilities are endless, but with storage still in the microwatt to one milliwatt range, it's more concept than solid vaporware reality.
Microsoft manager teams up with teens to build a fusion reactor in his garage (video)
Normally, if a grown man talks about building a fusion reactor and wants your 13-year-old to hang out in his garage, we'd expect you to smile, back away slowly, and perhaps alert the authorities. But, if that man is Microsoft program manager Carl Greninger there's no need to run. The science fanatic recruited a team of teens, as young as 13, and worked with them to build a Farnsworth–Hirsch Fusor -- a (comparatively) simple nuclear reactor that smashes together atoms and produces neutrons. Check out the nearly 20-min video after the break to watch a bunch of high school kids generate ball of ionized plasma. And to think, all that's in your garage is that '65 Mustang you swear you're gonna restore one day.
Blood turbine to power your pacemaker, become legendary band name
Why bother with risky battery-changing surgical operations when your own cardiovascular system can provide all the power your heart-shocking pacemaker will ever need? Engineers at Switzerland's University of Bern have been working on tiny turbines; turbines small enough, in fact, to fit inside a human artery. Working like a blood powered hydroelectric generator, a working prototype -- tested in a simulated artery -- has been able to produce 800 microwatts of electricity. That's roughly eighty times the power required to power the average pacemaker; such a device could provide independent, sustainable power to neurostimulators, blood-pressure sensors, and other implanted medical gizmos. Researchers are concerned, however, that a blood turbine's adding agitation of blood flow might lead to clotting, and are continuing to tweak and rework the design to minimize this risk. Similar, but unrelated cardiovascular power designs have attempted to alleviate the concern by doing away with the rotating, fluid powered components, opting to generate electricity by oscillating magnets by utilizing changes in blood pressure -- which sounds awesome, but still falls shy of "blood turbine," in the contest for most Metal medical device.
NASA makes longer, straighter piezoelectric nanowires in microgravity, no flat iron needed
Piezoelectric nanowires are the stuff that make power-generating pants a possibility, and that prodigious potential has drawn the attention of NASA. You see, self-powered spacesuits are awfully attractive to our nation's space agency, and a few of its finest student researchers have discovered that the current-creating strands of zinc oxide can be made longer and straighter -- and therefore more powerful -- when freed from gravity's unrelenting pull. That means nanowires grown in microgravity could lead to higher capacity batteries and the aforementioned juice-generating interstellar garb. Of course, there's no such end-products yet, but let's see if NASA can do what others have not: give pants-power to the people.
Nanogenerators produce electricity by squeezing your fingers together, while you dance
It's been a while since we last heard about nanogenerators -- you know, those insanely tiny fibers that could potentially be woven into your hoodie to juice up your smartphone. Dr. Zhong Lin Wang of the Georgia Institute of Technology has reported that he and his team of Einsteins constructed nanogenerators with enough energy to potentially power LCDs, LEDs and laser diodes by moving your various limbs. These micro-powerhouses -- strands of piezoelectric zinc oxide, 1 / 500 the width of a single hair strand -- can generate electrical charges when flexed or strained. Wang and his team of researchers shoved a collection of their nanogenerators into a chip 1 / 4 the size of a stamp, stacked five of them on top of one another and can pinch the stack between their fingers to generate the output of two standard AA batteries -- around 3 volts. Although it's not much, we're super excited at this point in development -- imagine how convenient to charge your phone in your pocket sans the bulky battery add-ons. And that's only one application of this technology. Yea, we know.
TUAW Tip: Generate iTunes Store RSS feeds

If you want to share that data on your website, or even if you just want it in your RSS reader, you can use the official iTunes RSS Generator to get the right feed. You can refine the RSS feed created by Country, Media Type, Feed Type, Size and whether to allow explicit content. The Media Types available include Music, Podcasts, Audiobooks, TV Shows, Music Videos, Movies, Mac Apps and Apps. There are obviously many options under each media type, so you should check it out and see what's available. Just punch in the criteria you want to follow, hit "Generate" and then hook up that feed to an RSS reader, and you'll be kept up to date on the latest changes in the iTunes stores.
Inhabitat's Week in Green: pencil-tip generators, the Nissan Leaf, and the world's largest wind turbine
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week we saw renewable energy take the world by storm as Spain announced plans to construct the world's largest wind turbine and a team of engineers made waves with plans for an underwater turbine modeled after whale flippers. We also saw Boeing shine light on plans to produce a new breed of ultra-efficient solar panels that are suited for space, while researchers in Japan developed a potent new kinetic generator that's as tiny as a pencil tip. Innovative eco transportation also picked up the pace as China rolled out plans to produce the first fuel cell powered light rail train and the world's largest solar-powered boat made its successful maiden voyage across the Atlantic. We also applauded the Nissan Leaf as it took first place as the European Car of the Year and we were wowed by Mercedes' next-generation concept car, which may one day be grown in a lab. We also showcased several new ways that technology stands to wire our lives -- starting with an electronic smart wallet that curbs spending by clamping shut like a clam. We also looked at Harvard's plans for a laptop computer powered by biogas and we were impressed by Nike's next-gen design tools for producing environmentally efficient clothes. Finally, we wrapped up the week with two exciting advances in tablet tech - India is testing a solar-powered I-Slate tablet geared at children in need and Substrata rolled out a gorgeous wooden iPad case that goes light on the earth.
TUAW's Daily App: mScribble
Bebot is still one of my favorite apps on the App Store, and mScribble, a recently revamped app from Appular and a developer named Panpipes Ho!, reminds me a lot of Bebot in its simplicity and versatility. That's pretty high praise indeed if you're as big a fan of Bebot as I am, but if you've never heard of Bebot, let me explain. mScribble is an app that generates a melody for you on the fly. The app plays a simple drum beat in the background with whatever rhythm you want -- there are nine to choose from in the app's menu). Drawing a scribble on the screen plays notes in a melody that's already lined up to the tune. It sounds complicated, but the app does all of the hard work -- just swiping across the screen gives you music, and with a little bit of practice, you can make some really interesting tunes by just playing around. Unfortunately, it's not quite as friendly to professional musicians as Bebot. This is more of a music generator than an actual instrument, and there aren't as many options. Each tune can play four tones, but you're pretty hard-coded to the drums in the background. But that's a plus for less experienced players -- it means that anyone can sit there, swipe across the screen, and create an interesting melody. It's a lot of fun, and just the ten minutes of random joy I spent playing around with the app was more than worth the buck they're charging for it. I'd like to see the idea developed even further (and Bebot is an excellent model), but for just swiping up a tune, mScribble is a great experience.
