Homeowner of solar-hydrogen house has $0.00 utility bill
Mike Strizki, a civil engineer living in New Jersey has converted his home into a completely energy self-sufficient abode that runs exclusively on a combination of solar and hydrogen power. Using solar panels, a hydrogen fuel cell, storage tanks, an electrolyzer to split water into Hydrogen and Oxygen, plus a custom made fuel-cell car, Mike benefits from a utility bill of zero dollars, and the comforting feeling that his activities don't produce any pollution. Currently the solution isn't in any way practical for mass adoption -- the initial cost was $500,000, with half paid by New Jersey state grants -- but Mike thinks that he could reduce this cost tenfold with more research and mass market production lines. There is also some concern amongst experts like Joseph Romm, a former Department of Energy official who thinks that the current relatively inefficient technology and the high cost means that this isn't a viable system for mass adoption just yet. Despite this criticism, Mike says "we have to start somewhere," even if early adopters (in this case rich Hollywood types with a conscience) are required to pay out up to $250,000 dollars to get in on the clean energy action.

CeBIT showcases looming trend: TV through the AC outlet
Piping internet, audio, and other bits of entertainment through one's power sockets has been available for some time now, but due to its less-than-impressive results in a majority of scenarios, it never really blossomed as a reliable networking option. Don't tell the folks at CeBIT this, however, as firms such as Devolo and Channel Vision are showcasing yet another shot at taking advantage of cabling already wired throughout your domicile. As expected, the technology converts the signals emitted from your set-top-box into an IP signal, which can then be streamed to other rooms or even other gizmos such as portable video players. Interestingly, there was no mention of HD abilities, and the Devolo system can currently only deliver the same digital channel being viewed to other areas, but the company is reportedly working on a future iteration to beam separate shows to different sources. Both pricing and availability details ran par for the course, as none of the kiosks displayed any information of the sort, but judging by the sheer interest shown here, it (hopefully) can't be too far off.[Via Wired]Read - Devolo demonstrationRead - Channel Vision demonstration
A123Systems crafts long-lasting automotive Li-ion for electric cars
A123Systems most certainly won't go down as the first startup to crank out what could be the batteries that reside in our future electric vehicles, but it seems to be edging ever closer to landing a full-blown contract with General Motors. GM has already selected the Massachusetts-based company to "develop batteries that might be used for the Saturn Vue," and it is pondering the idea of awarding the battery maker a similar deal for the Volt. The firm is garnering a good bit of praise for its "long-lasting, safe rechargeable Li-ions" that could potentially power the all-electric / hybrid vehicles of the future, but rather than relying on "cobalt oxide, it used iron phosphate assembled in a novel, nano-structure." Interestingly, the outfit's current offerings started out with the idea of utilizing self-assembling cells, but after they proved "intractably hard to develop," the idea was scraped in favor of the less pricey Li-ion approach. Still, don't expect these guys to run the table on automotive contracts, as there's already quite a few formidable opponents on the loose.
Energy-efficient Deepglider scours the ocean for scientific data
The University of Washington's Deepglider won't go down as the first manmade projectile to scour the ocean for random (albeit useful) tidbits of information, but it does sport an ultra-modern frame and energy source that certainly sets it apart. Similar to the nuke detector, Edinburgh Duck, and the bevy of other submarines used for the benefit of mankind, this concoction is used to capture underwater data to aid researchers in discovering more about global warming and seafloor conditions, but its autonomous nature and carbon fiber enclosure gives it the ability to remain underwater "for up to a year" and sink to depths of nearly 9,000 feet. The 71-inch long, 138-pound device carries sensors to measure "oceanic conditions including salinity and temperature," and when not patrolling the seas based on satellite-driven controls, it can transmit the data remotely using the same signal path in reverse. Notably, the torpedo-like device boasts an energy-efficient, battery-powered design that allows it to stay submerged for ridiculous amounts of time without needing a recharge, and while we're not too sure if its researchers are too caught up in its unmatched diving abilities to notice how swank the power system is, they've apparently got a good thing going.
Modded flashlight doubles as cellphone charger
Although most modern phones can go quite a few hours sans an AC outlet, we understand the need for juice in unexpected emergencies, and while the solar-powered charger does a fair job at high noon, you'll probably need a different approach come nightfall. Tackling two issues in one fell swoop is the cellphone-charging flashlight mod, which not only provides a beacon of light for those dim excursions, but also offers up hand crank recharging abilities for your fading mobile. Of course, hacking your flashlight to pull double duty as a manually powered charger is a bit more complex than just picking up a hamster or bicycle-powered option, but you've got to admit, crafting a makeshift charger with spliced cables and a soldering iron is totally MacGyver-approved. So if you're interested in giving yourself (and your handset) a bit longer life when robotic overlords eventually invade our domiciles, be sure to hit the read link for a video demonstration, and do mind the managerial cat on duty.[Thanks, Kipkay]
Corncob waste could enable methane use in vehicles
Aside from the obvious choice, there's vehicles scooting around on bioethanol, batteries, fuel cells, and all sorts of other alternatives, but a recent breakthrough in Kansas City, Missouri has opened up the possibility of using natural gas. Currently, the cheaper and cleaner burning methane isn't feasible in modern vehicles due to the extremely high pressure (3,600 psi) and gargantuous tanks required to actually use it. Researchers at the University of Missouri-Columbia and Midwest Research Institute in Kansas City have devised a way to change all that, however, by using corncob waste to create "carbon briquettes with complex nanopores capable of storing natural gas at an unprecedented density of 180 times their own volume and at one seventh the pressure of conventional natural gas tanks." In layman's terms, this discovery allows natural gas to be held under much less pressure and in thin-walled tanks similar to cells used on current vehicles, which could instantly make natural gas a viable (and readily available) alternative fuel source. A prototype system has been working just fine since last October, and the backers are currently crafting a second revision in hopes of storing even more natural gas and driving production costs down, but there's still no hard deets on when this invention could see commercial light.[Via AutoblogGreen]
Australia to phase out incandescent bulbs by 2010
While some US cities like Raleigh are already planning steps to cut back on energy wastes by converting to more efficient lighting systems, it looks like the entire continent of Australia could be following suit. Claiming to be the "world's first" national government to phase out incandescent light bulbs in favor of the more "fuel-efficient, compact fluorescent bulb," environment minister Malcolm Turnbull is hoping to "cut Australia's greenhouse gas emissions by four million metric tonnes a year by 2015." Citing the "climate changes" the world is facing as a "global challenge," Turnbell also urged other nations to follow suit in making a difference, but didn't exactly open up his personal wallet to stock our households with those uber-pricey bulbs. Interestingly, some environmentalists feel that the bulk of greenhouse gas emissions come from government and business-related activities, which should presumably take priority over swapping out a country's light bulbs. Still, we've got no complaints with hooking homes up with LED / fluorescent options to help Mother Earth, but shouldn't Australia (and America, too) ink its name on the Kyoto Protocol before getting all high and mighty about saving the planet?
Steorn Orbo: the thermodynamics defying energy product is named
We wrote about Steorn last year when they took everyone by surprise with a full page ad in The Economist, and a (not so) simple promise: that they'd discovered a clean, perpetual energy system that would solve the world's energy problems. While we're not exactly any closer to knowing what this supposed thermodynamics and physics bending energy production mechanism actually is, Steorn has given it a name: Orbo. Detailed specs on the Orbo energy system are promised by the end of Q1 of this year; until then, with the scientific community all up in arms over promises to end the concept of energy scarcity and thereby transform the world economy, our enthusiasm is and will still remain curbed by our skeptics' hat which we can't take off (not even for a second).
VentureOne three-wheeled hybrid does flex-fuel
We most certainly dig where this uber-green three-wheeled vehicle category is going, as just one week after seeing the Silence PT2, we've now learned that Venture Vehicles will be tossing the two-wheeled axle in the rear and calling its rendition the VentureOne. Based around Carver Engineering's tilting technology, this trike is officially classified as a motorcycle, but sports a fully enclosed body, roll-cage construction, airbags and bumpers similar to a standard car. The vehicle will hold three folks, and the company has plans for two plug-in hybrid variations that utilize a flex-fuel approach to barely sip gasoline from the four gallon tank, all while touting 100 miles per gallon and the ability to hit speeds upwards of 100 miles per hour; eventually, Venture is also hoping to release an all-electric breed that can scoot 200 miles before needing a recharge. Although production isn't slated to begin until "late 2008," that should give you enough time to save up a good chunk of the $18,000 (E50 hybrid) to $23,000 (all-electric model) that'll be required to snap one up -- and to acquire a motorcycle license, too.[Via Gizmag]
Motion-sensitive "power skins" could generate power in space
Just in case you ever plan on heading up into space to see your soon-to-be-painted logo on the Y*N*I*S satellite up close and personal, you might be interested in this. Devised by researchers at a Cambridge-based venture, dubbed IntAct Labs, the motion-sensitive "power skin" could be used and worn by humans and inanimate objects alike in order to generate electricity, and the concept was derived from our very ears. After investigating how biological organisms are such "ultra-efficient generators of power," the crew homed in on a tiny protein called prestin, which can "convert electrical voltage into motion or produce electrical charges in response to mechanical stresses," and is actually found in the outer hair cells of the human ear. Ideally, networks of these proteins would be linked in order to form skins that could coat people or objects and generate energy from something as simple as walking around or being in the path of wind gusts, and if everything pans out, a prestin-powered research station could be set up on Mars without a manmade perpetual power source in tow.[Thanks, Sparky]
Software patch could boost MPG in gas-powered vehicles
No doubt, we've seen more than a few sensational sounding gizmos aiming to provide (nearly) limitless power and create energy out of thin air, but a simple software patch could enable the vast majority of the world that's still stuck in gasoline-powered vehicles to get better gas mileage. John Kessels at the University of Eindhoven has partnered with Ford to develop software to improve engine performance and save "up to 2.6-percent" in terms of miles per gallon. Quite simply, the patch dynamically switches the dynamo, (which charges the car battery) on and off when it is "particularly inefficient for the engine to power it, thus improving the overall efficiency of the engine." Mr. Kessels even stated that "a simple cable and a software upgrade" was all that would be necessary to boost MPG, and thankfully it's not exclusive to Ford motors. Notably, a fuel savings closer to six-percent could likely be achieved if a "powerful starter motor" was installed to allow your engine to cut off entirely and restart quickly in between long traffic jams, but both methods have a good bit of testing to go through before being deemed non-abrasive to batteries and engine components. But hey, there's nothing a firmware upgrade can't fix, right?
Microfluidic computer runs on bubbles, deals in chemical analysis
Flipping over to alternate energy sources isn't just the rage in vehicles, as we've seen steam-powered and string-powered computers already, and now we're witnessing an oddity that's actually energized by bubbles. The "microfluidic" computer performs calculations by squeezing bubbles through tiny channels etched into a chip, and although it runs around 1,000 times slower than you're average desktop today and takes up quite a bit more room, no AC outlet is required to churn out chemical analysis. Manu Prakash and Neil Gershenfeld of the MIT Center for Bits and Atoms created the devices by "etching channels about one micron wide into silicon, and then using nitrogen bubbles contained in water to represent bits of information flowing through these channels." The computer utilizes Boolean logic functions to carry out its work, and the researchers are already envisioning it carrying bubbles of molecules or individual cells to "conduct diagnostics or detect pathogens." We'll admit, a bubble-powered PC ain't too shabby, but even proponents fessed up that such a snail isn't putting modern day machine vendors out of business anytime soon.
Silence PT2 rocks three wheels, all electric powertrain
Getting word of a new electric car hitting the pavement is (thankfully) becoming quite common these days, but crafting a vehicle that's made it a few steps beyond the easel is certainly noteworthy. Silence, Inc., a mash-up of Canada's EBW and T-Rex, has set out to "design and build high-performance electric vehicles," and the company's first attempt looks to be a winner. The three-wheeled PT2 certainly has a flair for the dramatic, as its metallic paint, vivid interior, and overall dashing good looks make it a sight for sore eyes in the fully electric vehicle department, and as if that weren't good enough, this bad boy can reportedly cruise 125 to 250 miles on a single charge, hitting speeds "around 125-miles per hour" along the way. Silence states that its PT2 will be "available for ordering" sometime this Spring, but folks with enough interest (and the spare loot to back it up) can hit them up right now to get on the short list, and for those already glancing away to save yourself the pain from viewing the pricetag, remain focused -- this hotrod will only run you around $50,000CDN, or just over 42 large here in the US.

Portable generator converts waste into energy
Although developing alternate fuel sources is most certainly a worthwhile effort, a group of Purdue scientists are looking to demolish two birds with a single, um, bag of refuse, as its portable generator not only creates useful electricity, but it disposes of worthless garbage while it's at it. The aptly-named "tactical biorefinery" processes several kinds of wastes at once, which it then converts into fuel via two parallel processes before burning the results in a diesel engine to power a generator. The device, which comes in just a hair smaller than a "small moving man," can crunch through multiple kinds of garbage at once, creating energy completely without discrimination towards certain kinds of gunk, and is already being eyed by the US Army for future battlefield usage. Interestingly, initial prototypes are showing that it can produce "approximately 90 percent more energy than it consumes," and considering that it pulverizes everything inserted into it, soldiers won't have to worry about leaving behind remnants of their stay. Ideally, the backers would love to see the unit available in commercial settings as well as in the military, but we think this thing will be a real winner when it can compress gobs of garbage into vicious (smelling) pellets and launch grotesque projectiles while keeping our planet green.[Via CNET]
Power your PSP with a trio of AAA batteries
For those of you who just can't get enough playtime with your ever lovin' PlayStation Portable, and have a knack for running low on juice while not even remotely close to an AC outlet or recharging venue, here's a mod that can offer you some battery powered backup for your handheld Sony. Not at all for the faint of heart or the novices in the house, this battery hack joins the incredibly long list of hackerations that we've seen come the PSP's way, and while it takes a bit more effort than just picking up the X2, we're sure the bragging rights alone make it worthwhile. The crafty gurus over at Acidmods have apparently found a way to gut, re-wire, and completely transform your average PSP battery pack into a vessel that can hold a trio of AAA cells in order to power your bantam machine. Admittedly, this ranks pretty far right on the DIY difficulty scale, so we wouldn't recommend risking your life on this one unless you know quite a few tricks of the trade, but if you've nothing better to do on a Sunday afternoon than create a battery pack out of a battery pack, the read link is waiting for your attention.[Via PSPFanboy]
Medis Technologies unveils portable fuel cell power pack
Yeah, we won't even need fuel cells as soon as EEStor's miracle-working ultracapacitor-based battery system starts powering the world at large, but until then, we're still fielding applications for alternative sources of juice. Medis Technologies has introduced a fuel cell for your pocket, which provides auxiliary power for cellphones, DAPs / PMPs, PDAs, digicams, and pretty much anything else that relies on an internal, rechargeable battery. Touted as being "years ahead of its time," this self-proclaimed must-have gadget works off a Direct Liquid Fuel Cell (DLFC), and can supposedly provide up to 30 hours of talk time to any mobile, and between 60 and 80 hours of playback time for your iPod. Of course, there are no hard details promising us when we'll see this portable power unit, nor any indication of how expensive it'll be when it finally lands, but if lofty life claims turn out to be true, it might not be too shabby.[Via PocketPCThoughts]
Domia's Bye Bye Standby kills power en masse
Although that handy Kill-A-Watt device might do a number on showing you just how much energy your array of consoles and AV equipment is sucking down each time you power up, it won't do much anything to stop the electrical bleeding. Enter Domia, which offers up a full range of Bye Bye Standby products to shut off power en masse to home or office electronics. Essentially, the lineup of products provides specialized, wirelessly-enabled Smart Socket middlemen that can connect to wireless toggle switches via your PC, a wall-mounted "Green Switch" button, a cordless remote, or even a voice recognizing microphone. By switching the channels on your sockets, you can power down up to four (or more, if using a power strip) devices at a time, and each allows you to manually override it if you decide to crank one or two back up. If you're curious about just how much loot you'll save by powering down your pad whenever possible, Domia estimates a £40 ($79) savings "for a family of four," but for those of you already stingy with the light switch, the benefits could be marginal. Notably, this product appears to play nice with UK-based power outlets only, and considering the British wishes to outlaw standby buttons entirely, you may want to hold off of this here £29.99 ($59) purchase until the politics shake out.
AIST turns transparent glass into mirrors to conserve energy
We've seen two-way displays and undercover mirrors before, but the latest two-faced invention to come from the depths of the National Institute of Advanced Industrial Science and Technology (AIST) can pull double duty in regard to purpose and save a little energy in the process. The "switchable glass" has certain reflexive properties created by the twin coatings of "40-nanometer-thick magnesium-titanium alloy, plus a 4-nanometer-thick layer of palladium," which allows for the mirror to become transparent when a small amount of hydrogen is introduced between the two panes. Alternatively, tossing in a bit of oxygen forms a reflecting mirror, allowing users to "switch" the glass by injecting gases. Contrary to other commercialized approaches, this rendition can purportedly result in up to a "30-percent savings in energy costs" by having to run your air conditioner less, but there's still work to be done. Scientists at the AIST are still toiling away as they try to fight the relatively rapid deterioration that occurs from "frequent switching," but if they can add a dash of durability and get the price down to a respectable level, we could all be living in a house of mirrors before too long.[Via PlasticBamboo]
Researchers develop closed hydrogen fuel cell system
If EEStor's elaborate claims are to be believed, we suppose all these other fuel alternatives should just hang up the gloves while they're at it, but just in case things don't pan out so well, we suppose the continued research in hydrogen fuel cell power isn't such a bad idea. Although we've seen glimpses of hydrogen-powered vehicles (and um, crafts) in the past, most of these modes of transportation have been large-scale, and now it seems that a closed system has been crafted which would make these techniques suitable for more diminutive applications such as chainsaws and lawnmowers. The research team has reportedly found a way to better control the way the fuel is used, thus eliminating the need for costly recycling stations, and they insinuate that their findings are "ideal" for devices currently using small internal combustion engines that lack emissions controls. Of course, the system has yet to be broadly trialed, but if things go as planned, there's even hopes to link several of the new cells together to rival the power of cells currently being tested in the automotive industry.
EEStor unveils ultracapacitor-based battery system, Li-ion shudders in fear
If relying on sunlight and downhill routes in Venturi's uber-green Eclectic doesn't exactly sound feasible for your everyday (and night) errands, and your ultraportable's five hours of battery life just isn't where you think it should be, EEStor is hoping to remedy those issues -- along with basically every other battery-related quandary -- in one fell swoop. In another case of "this just can't be for realz," an elusive Texas company is coming clean about what's been happening in its labs of late, and the proclamations are nothing short of sensational. The firm boldly states that its one of a kind system, a "battery-ultracapacitor hybrid based on barium-titanate powders, will dramatically outperform the best lithium-ion batteries on the market in terms of energy density, price, charge time, and safety." Moreover, this miracle-working solution is said to produce "ten times" the power of lead-acid batteries at half the cost, sans the need for "toxic materials or chemicals." Additionally, EEStor is hoping to have its Electrical Energy Storage Unit (EESU) powering the wheels of Toronto-based ZENN Motor vehicles, and if "estimates" are to be believed, it will only take about $9 worth of electricity for an EESU-propelled car to travel 500 miles, compared to nearly $60 in gasoline. Of course, such a "breakthrough" product is bound to have its fair share of naysayers, and Jim Miller, vice president of advanced transportation technologies at Maxwell Technologies, is indeed skeptical that EEStor's technology will be able to withstand the unique pressures that a vehicle would place on the "brittle" structure. But we've got to give credit to the company's vow to veer clear of hype, as it notes that this is just the first time it has come forward to intro the technology, and maintains that it will "meet all of its claims" -- guess we'll see about that, eh?[Via The Raw Feed]
