Kill-A-Watt’s latest version lets you see three stats at once: the current voltage, elapsed time and cumulative use (which has an unfortunate abbreviation). You also get the programmable functionality, letting you set up unique times for each day of the week and 96 on/off settings per day. It’s also a surge protector, which I’m not sure the old one had.

You’ll have to pay $US70 for this updated version, which still only supports one outlet at once, as opposed to the $US10-$20 that you can get the original for. [ThinkGeek]

According to the witches and wizards at NEC Electronics and Onryoku Hatsuden, their new remote generates electricity when the users clicks on any button. They are planning to see the first production remotes in 2011. [Aiajin via Crunchgear]

It’s only a prototype at the moment (one of many that have come out lately focused on saving energy), which probably explains why it still looks like a child’s toy. Not a good idea when you consider that it sits between the wall outlet and the plug of your gadget. At any rate, PowerZoa transmits details on your power usage to a secure website, where you can use the interface to turn specific devices on or off.

Sooner or later something like this will be widely available, and there will be a mobile phone app that would allow me to control everything. And when that happens, I will be all over it. [Powerzoa via DVICE]

Tokyo company HiBot is developing a robot to transfer the dangerous duties of high-voltage wire inspection from meat-based humans to metal-based robots, in a move intended not just to decrease the likelihood of flash-frying technicians, but to make the inspection process — vital, now that many countries’ electrical infrastructures have components approaching 100 years old — more efficient.

The HiBot Exliner, pictured above and set to deploy in Japan, is the second such robot, and the most ambitious: While the LineScout, pictured at top and currently in trials in Canada, only inspects one line at a time, the Expliner will cover four. And unlike their human counterparts, Exliner and LineScout don’t even care if the lines are left active while they’re doing their respective things, because they ain’t got nothin’ to lose, y’know? Also: because they’re properly insulated. [IEEE via Make]

There’s no real info on this thing, but it appears to offer most major plug types by spinning the three segments around. It’d be the perfect thing to put in hotels, where people are continually unable to charge up their razor or laptop. [GadgetLab]

The more you look at the writhing orgy of plugs in the world, the sillier it seems. If you buy a phone charger at the airport in Sydney, you won’t be able to use it when your flight lands in Paris. If you buy a three-pronged adaptor for le portable in France, you might not be able to plug it in when your train drops you off in Germany. And when your flight finally bounces to a stop on the runway in London, get ready to buy a comically large adaptor to tap into the grid there. But that’s cool! You can take the same adaptor to Singapore with you! And parts of Nigeria! Oh yeah, and if said charger doesn’t support 240v power natively, make sure you buy a converter, or else it might explode.

And aside from a few oases, like the fledgling standardisation of the Type C Europlug in the European Union, this is the picture all across the world.

I’d hesitate to refer to power sockets as a part of a country’s culture, because they’re plugs — they don’t really mean anything. But in the sense that they’re probably not going to change until they’re forcefully replaced with something wildly new, it’s kind of what they are.

What’s Out There

Click for larger.

There are around 12 major plug types in use today, each of which goes by whatever name their adoptive countries choose. For our purposes, we’re going to stick with US Department of Commerce International Trade Administration names (PDF), which are neat and alphabetical: America uses A and B plugs! Turkey uses type C! Etc. Thing is, these names are arbitrary: the letters are just assigned to make talking about these plugs less confusing — they don’t actually mandate anything. They’re not standards, in any meaningful sense of the word.

And even worse, these sockets are divided into two main groups: the 110-120V fellas, like the the ones in North America, and the 220-240V plugs, like most countries use, including Australia. It’s not that the plugs and sockets themselves are somehow tied to one voltage or another, but the devices and power grids they’re attached to probably are.

How This Happened

The history of the voltage split is a pretty short story, and one you’ve probably heard bits and pieces of before. Edison’s early experiments with direct current (DC) power in the late 1800s netted the first useful mainstream applications for electricity, but suffered from a tendency to lose voltage over long distances. Nonetheless, when Nikola Tesla invented a means of long-distance transmission with alternating current (AC) power, he was doing so in direct competition with Edison’s technology, which happened to be 110V. He stuck with that. By the time people started to realise that 240V power might not be such a bad idea for the US, it was the 1950s, and switching was out of the question.

Words were exchanged, elephants were electrocuted, and eventually, the debate was settled: AC power was the only option, and national standardisation started in earnest. Westinghouse Electric, the first company to buy Tesla’s patents for power transmission, settled on an easy standard: 60Hz and 110V. In Europe—Germany, specifically—a company called BEW exercised their monopoly to push things a little further. They settled somewhat arbitrarily on a 50Hz frequency, but more importantly jacked voltages up to 240, because, you know, MORE POWER. And so, the 240 standard slowly spread to the rest of the continent. All this happened before the turn of the century, by the way. It’s an old beef.

For decades after the first standards, newfangled el-ec-trick-al dee-vices had to be patched directly into your house’s wiring, which today sounds like a terrifying prospect. Then, too, it was: Harvey Hubbell’s “Separable Attachment Plug“—which essentially allowed for non-bulb devices to be plugged into a light socket for power—was designed with a simple intention:

My invention has for its object to…do away with the possibility of arcing or sparking in making connection, so that electrical power in buildings may be utilized by persons having no electrical knowledge or skill.

Thanks, Harvey! He later adapted the original design to include a two-pronged flat-blade plug, which itself was refined into a three-pronged plug—the third prong is for grounding—by a guy named Philip Labre in 1928. This design saw a few changes over the years too, but it’s pretty much the type we use now.

Here’s the thing: Stories like that of Harvey Hubbell’s plug were unfolding all over the world, each with their own twist on the concept. This was before electronics were globalised, and before country-to-country plug compatibility really mattered. The voltage debate had been pared down to two, which made life a bit easier for power companies to set up shop across the world. But once they were set up, who cared what style plug their customers used? What were you gonna do, lug your new vacuum cleaner across the ocean on a boat? Early efforts to standardise the plug by organisations like the International Electrotechnical Commission (IEC) had trouble taking hold—who were they to tell a country which plug to adopt?—and what little progress they did make was shattered by the second World War.

Take the British plug. Today, it’s a huge, three-pronged beast with a fuse built right into it — one of the weirder plugs in the world, to anyone who’s had a chance to use one. But it isn’t Britain’s first plug, or even their first proprietary plug. In the early 1900s the Isles’ cords were capped with the British Standard 546, or Type D hardware, which actually include six subversions of its own, all of which were physically incompatible with one another. This worked out fine until the Second World War, when they got the shit bombed out of them by Germany, and had to rebuild entire swaths of the country in the midst of a severe shortage of basic building supplies — copper, in particular. This made rewiring stuff an expensive proposition, so the government was all, “we need a new plug, stat!”

Here was the pitch: Instead of wiring each socket to a fuse board somewhere in the house, which would take quite a bit of wire, why not just daisy-chain them together on one wire, and put the fuses in each plug? Hey presto, copper shortage, solved. This was called the British Standard 1363, and you can still find them dangling from wires today. Notice how all the way into the 1940s and ’50s—practically yesterday!—the UK was devising a new type of plug without any regard for the rest of the world.

Now imagine every other developed country in the world doing the same thing, with a totally different set of historical circumstances. That’s how we ended up here, blowing fuses in our Paris hotel rooms because our travel adaptors’ voltage warning were inexplicably written in Cyrillic. Oh, and it gets worse.

You know how the British had control over India for, like, 90 years? Well, along with exporting cricket and inflicting unquantifiable cultural damage, they showed the subcontinent how to plug stuff in the British way! Problem is, they left in 1947. The BS 1363 plug—the new one—wasn’t introduced until 1946, and didn’t see widespread adoption until a few years later. So India still uses the old British plug, as does Sri Lanka, Nepal and Namibia. Basically, the best way to guess who’s got which socket is to brush up on your WW1/WW2 history, and to have a deep passion for post-colonial literature. No, really.

Is There Any Hope for the Future?

No. I talked to Gabriela Ehrlich, head of Communications for the IEC, which is still doing their thing over in Switzerland, and the outlook isn’t great. “There are standards, and there is a plug that has been designed, the problem is, really, everyone’s invested in their own system. It’s difficult to get away from that.”

When Holland’s International Questions Commission first teamed up with the IEC to form a committee to talk about this exact problem in 1934. Meetings were stalled, there was some resistance, blah blah blah, and the committee was delayed until 1940. Then a war—a World War, even!—threw a stick in the committee’s spokes, (or a fork in their socket? No?), and the issue was effectively dropped until about 1950, when the IEC realised that there were “limited prospects for any agreement even in this limited geographical region (Europe)”. It’d be expensive to tear out everyone’s sockets, and the need didn’t feel that urgent, I guess.

Plus, the IEC can’t force anyone to do anything — they’re sort of like the UN General Assembly for electronics standards, which means that they can issue them, but nobody has to follow them, no matter how good they are. As time passed, populations grew, and hundred of millions of sockets were installed all over the world. The prospect of switching hardware looked more and more ridiculous. Who would pay for it? Why would a country want to change? Wouldn’t the interim, with mixed plug standards in the same country, be dangerous?

But the IEC didn’t quite abandon hope, quietly pushing for a standard plug for decades after. And they even came up with some! In the late ’80s, they came up with the IEC 60906 plug, a little, round-pronged number for 240V countries. Then they codified a flat-pronged plug for 110-120V countries, which happened to be perfectly compatible with the one already used in the US. As of today, Brazil is the only country that even plans to adopt the IEC 60906, so, uh, there’s that.

I asked Gabriela if there was any hope, any hope at all, for a future where plugs could just get along:

Maybe in the future you’ll have induction charging; you have a device planted into your wall, and you have a [wireless] charging mechanism.

Last time I saw a wireless power prototype was at the Intel Developer forum in 2008, and it looked like a science fair project: It consisted of two giant coils, just inches apart, which transmitted enough electricity to light a 40W light bulb. So yeah, we’ll get this power plug problem all sorted by oh, let’s say, 2050?

She took care to emphasise that the standards are still there for people to adopt, so countries could jump onboard, but even in a best-case scenario, for as long as we use wires we’ll have at least two standards to deal with — a 110-120V flat plug and the 240-250V round plug. For now, the Commission is taking a more practical approach to dealing with the problem, issuing specs for things like laptop power bricks, which can handle both voltages and come with interchangeable lead wires, as well as as something near and dear to our hearts: “We have to move forward into plugs we can really control,” Gabriela told me. She means new stuff like USB, which is turning into the de facto gadget charging standard. The most we can hope for is a future where AC outlets are invisible to us, sending power to newer, more universal plugs. My phone’ll charge via USB just as well in Sub-Saharan Africa as it will in New York City; just give me the port.

In the meantime, this means that things really aren’t going to change. Your K-Mart shaver will still die if you plug it into a European socket with a bare adaptor, Indians will still be reminded of the British Empire every time they unplug a laptop, Israel will have their own plug which works nowhere else in the world, and El Salvador, without a national standard, will continue to wrestle with 10.

In other words, sorry.

Actually, that’s four hours on a 3-phase 400V/32 source. It takes 28 hours on a standard, European 220V outlet. To put the benefits of an electric-powered boat in perspective, consider this: a full charge only runs about five euros (about $8). The boat may be priced 30 or 40 per cent higher than an equivalent diesel powered craft, but you could save money over the 10-year life of the battery on fuel costs.

Sounds great, but if you have the means it might be worth waiting a bit longer for Nimbus to improve the technology. Apparently, a new generation of batteries that can double the range will be available “soon”. That would make it a serious competitor will diesel boats in terms of performance while offering you more juice to rig up a way to electrocute fish. [Nimbus via Luxist]

Nothing in this world can take the place of persistence, and William Kamkwamba has it in spades. At age 14, while many of us were sneaking out of classrooms, William was struggling to sneak into them — his family was unable to afford the $US80 annual tuition. As is bound to happen to most students, he was caught. But instead of being sent to detention, he was barred from the school. In a show of the driven man he would become, he didn’t allow that to hinder him and instead started spending his days in the local library. While there, he encountered a book called Using Energy:

Using Energy described how windmills could be used to generate electricity. Only two percent of Malawians have electricity, and the service is notoriously unreliable. William decided an electric windmill was something he wanted to make. Illuminating his house and the other houses in his village would mean that people could read at night after work. A windmill to pump water would mean that they could grow two crops a year rather than one, grow vegetable gardens, and not have to spend two hours a day hauling water. “A windmill meant more than just power,” he wrote, “it was freedom.”

This book is what changed his life. And I don’t mean that as an exaggeration. It was truly what made a difference in his life. Because of that book, and the potential he saw in its ideas, William began to build:

William scoured trash bins and junkyards for materials he could use to build his windmill. With only a couple of wrenches at his disposal, and unable to afford even nuts and bolts, he collected things that most people would consider garbage-slime-clogged plastic pipes, a broken bicycle, a discarded tractor fan-and assembled them into a wind-powered dynamo. For a soldering iron, he used a stiff piece of wire heated in a fire. A bent bicycle spoke served as a size adaptor for his wrenches.

Imagine that. A young boy being so motivated by ideas and the sheer need to build something life-changing that he discovered materials and uses for them which most of us wouldn’t even dream of. As Mark Frauenfelder put it:

For an educated adult living in a developed nation, designing and building a wind turbine that generates electricity is something to be proud of. For a half-starved, uneducated boy living in a country plagued with drought, famine, poverty, disease, a cruelly corrupt government, crippling superstitions, and low expectations, it’s another thing altogether. It’s nothing short of monumental.

After completing his first windmill, William “went on to wire his house with four light bulbs and two radios, installing switches made from rubber sandals, and scratch-building a circuit breaker to keep the thatch roof of his house from catching fire”. His project had the attention of village locals early on, but at this point he gained the attention of TED, Technology Entertainment Design, through whom he was introduced to individuals willing to contribute to his plans to “electrify, irrigate, and educate his village, as well as pay his tuition at the prestigious African Leadership Academy in Johannesburg.”

In short: A young man struggled to educate himself, to build something his village needed, and in the end made a difference to the entire locale and gained the education he’d always wanted. Yes, it’s a fluffy, feel-good story with a happy ending. What should you take from the it? Maybe that there’s hope in the bleakest of situations, maybe that your teachers and parents were right about the power of education, maybe just that I’m a sappy bookworm with a soft spot for happy endings. No matter, if you wish to learn more, you can read the recently released The Boy Who Harnessed the Wind, check out William’s blog, or peek at this video from before he ever wrote his autobiography.
