I vaguely recall a Discovery article a while back that said that given today's solar cells it would only take 100 square miles of desert to meet the US's expected power needs for the next 20 years. And this was allowing for space such as preventing one panel from shadowing the other, roads, service buildings et al. I could look up the article....but then again, I'm sure there is someone else that knows how Google works.

Apuleius (6901) | more than 13 years ago | (#142934)

Your exercise bike came linked to a dynamo, so that you could use it to store up power in an array of rechargeables, so you could then then use a Zener diode setup to bypass the power supplies on some of your appliances (when and only when the batteries were up) and power them with the sweat of your brow? You could have an array of Zeners for each voltage level on your radio or other small appliances, and it wouldn't take too much soldering to hook these up. It would make a really cool demo, especially now that Fornicalia is having rolling blackouts and other states may soon as well.

bigger? (2)

Jeremi (14640) | more than 13 years ago | (#142935)

Correct me if I'm wrong, but if you made the spring and the crank larger (say 5 feet across) you could store much more energy in it, maybe have the it power the computer for a day?

Then add a second spring-and-crank mechanism, and a way to 'hot-swap' from the first to the second and back without interrupting the power flow, and you could have a web server that would run continuously, as long as you remembered to wind it up every morning.

Midnight Thunder (17205) | more than 13 years ago | (#142937)

This would almost be great for power cuts. When the server gets shut down because of the power-cut lasting longer than the UPS this thing could kick in. The reason I said almost is because while this solves the web-server problem it doesn't sort the problem of the optical-copper bridge, which most companies have, loosing power or the gateway loosing power.

A hand-powered webserver

Have you ever thought it'd be cool if you could have an environmentally-friendly computer ? I've always wanted one, I even powered my old ZX81 with a bicycle, a dynamo and a bridge rectifier circuitry once. Trouble is, even the poor little ZX81 needs a lot of pedaling to simply boot up.

Then, on Friday, I came across this hand-powered lantern while browsing the net, and the idea clicked in my head : the manufacturer of this little gem ships it with a 3V 650mA light bulb (1.95 W), and the uCdimm from Lineo needs 3.3V 350mA (1.155 W) at most, so the lantern should be able to power a uCdimm confortably.

So I called up a bunch of places here in Toronto and found one of these lanterns. When I came back to the office, our local electronics guru Sergey, our local geekhead Evan and myself took the thing apart, cranked up the spring and measured the voltage : without the lanterns' battery and light bulb, the internal DC generator spews out a heroic 5 V. Cool, that's perfect for a 3.3 V regulator and a uCdimm !

So I spent the week-end cleanly ripping the guts of the lantern out (it's surprising the amount of electronics this thing has inside), installing a 3.3 V regulator inside, a serial port and an ethernet port at the back, rewiring the power plug that used to serve as battery charging port to power the uCdimm while working on it, rewiring the button (that is also a clever brake to stop the spring from unwinding when the lantern is not in use).

The hardest was soldering a bunch of wires on the uCdimm's bus (man! those pads are tiny) and installing it nicely in lieu of the original light bulb and reflector.

One nice thing about the uCdimm (apart its low power consumption of course) is that it boots into Linux quickly, which is crucial because the dynamo only provide a little over 2 minutes of power with 60 cranks, so every second spent booting up the board is a second lost that can't be used to browse.

So here it is : the "uCdynamo", the first webserver you can bring with you and use in a desert :-)

The uCdimm embedded in the front bezel, with a background image to make the whole assembly look a little better. The spring ran out of breath before I could finish taking the photo :)

The side of the lantern, showing the business end of the muscle power supply. The button controls the brake applied on the generator's large pulley, and the reset line on the uCdimm at the highest setting. The power led next to the button now serves as "health" monitor, just like on the uCevolution board.

The serial port, ethernet port and additional power plug sticking out at the back of the lantern.

The guts of the beast. You can see the gears demultiplicating the huge torque and low speed of the unwinding spring into a low torque high speed rotation to operate the generator.

Jeff reckons the generator has enough oomph to power an LCD display as well, and there's plenty of space left on the side of the lantern to bolt one on, so maybe we'll turn it into a hand-powered "handheld" some day :-)

Cheap Embedded Hardware? (2)

Mr. Slippery (47854) | more than 13 years ago | (#142943)

A better solution, though, would be to just use batteries. You will get a longer operating time and less carpal tunnel syndrome.

The thing about batteries, though, is that they always seem to have run out just when you need them most.

These hand-cranked gizmos are great for emergency or seldom-used gear, because you don't have to worry about batteries having been stored too long, or having run down. Maybe this would be a good way to power emergency-use-only cell phones? Crank it up to dial 911.

rsw (70577) | more than 13 years ago | (#142946)

You may as well not use Zeners. It's likely that you're going to store voltage between 12 and 24 volts, in which case, switching (dc-dc) converters are more efficient.

Zener regulator setups burn the excess voltage in order to get the proper output; switching converters will (ideally) only use as much power as the load is drawing (of course, it takes a little bit of power to run the switching logic, but that's no big deal). In particular, imagine that you want a 5V supply from a 12V battery, and further that you're drawing 100 mA. If you are using a Zener setup, you'll be pulling a full 1.2 Watts from the battery and only using 500 mW. With a switching power supply, you'll be getting the full 500 mW to the load; the control logic will likely use no more than 50 or 100 mW.

Since storing energy in batteries at higher voltages is more efficient, the payoff is likely to be even greater than this.

rkent (73434) | more than 13 years ago | (#142947)

That hardly ruined much, all it is, is 4 cages on polls.

When I said "land is already ruined," I meant because of its proximity to a major highway. Between noise pollution and air pollution and construction equipment driving all over the shoulders every couple of years, the land immediately surrounding a highway is pretty much a wasteland. And no one wants to LIVE there, so how about some server farms?

Anyway, you also have to consider that most of that land is indian reservation

The only res on I-10 between Tucson and Phoenix is the Gila River community, and that only occupies about the first 20 miles south of Tempe. That leaves about 80 miles of non-res land. Of course much of that is already taken, but there are still huge swaths of empty space which could work for something like this.


Re:Solar Servers (1)

rkent (73434) | more than 13 years ago | (#142948)

If solar power was actually efficient enough in a power/acre manner to run a frickin' data center, don't you think they would have already done it?

a) see "solar host" response below,
b) I did a little investigating and discovered that there are Kyocera cells that claim to operate at around 126 watts/sq meter, DC, under ideal conditions (total sunlight, etc). So you need to shave a bit off for the inverter and to allow for un-ideal light, but even at about a 10% discount for EACH of those, you get about 400KW per acre. I don't know what kind of datacenters you'd be running, but an acre isn't really a huge site, and 400,000 watts is a freakin' lot of power.

It would be waaay too cost prohibitive for anyone to even think of doing it.

That, unfortunately, is a very good point. For an acre of the Kyocera cells I was referring to, it would cost a cool $2.1 million. Not gonna happen soon.


Solar Servers (4)

rkent (73434) | more than 13 years ago | (#142949)

Oh, man. I've been thinking for years that they ought to just cover the land in Arizona with solar-powered server farms and commodity solar "generators." At least along, for example, I-10 between Tucson and Phoenix, where the sensitive ecosystem is already ruined (my first site nomination is that ludicrous abandoned amusment park near Eloy). With 300+ days of sun per year, the power supply would be rock solid as long as you had enough deep-cell batteries to get you through the monsoons. And you could probably collect way, way more power than you actually needed over the area of the server building, and actually push some back into the Grid.

It's win-win!

Well happens of course. However most accidents are entirely avoidable if you keep your skills up to date.

Most accidents arn't that bad either. Most damage comes either from wearing improper gear (just don't do that, the goo dstuff only costs a few hundred $$, will still be good after a crash (not counting helmets) and is comfortable at speed even on hot days), hitting objects (avoid them), or being run over by cars (hard to avoid yourself but...most cars hit the breaks when you go down)

Re:Solar Servers (2)

ParisTG (106686) | more than 13 years ago | (#142958)

At full sunlight intensity, the sun outputs about 1000W/square meter. Most common solar cells right now are about 15% efficiency (although you can get them commercially at atleast 22%), where you'd get about 150W/sq. meter at full sunlight. That's not too bad, considering 8 sq. meters of these solar cells can propell a solar car [] at well over 100km/h.

To support your point, there was a story on /. a short time ago (sometime in the past two weeks) about a company creating UPS systems based on flywheel technology. The idea is similar - using something besides batteries or "the grid" to supply power to a machine.

I'm all for alternative forms of power, but the things that keep holding everything back are twofold: (1) consumers are cheap and only want to spend as little as possible; (2) alternative forms of power (batteries, solar, wind, geothermal) are expensive and not nearly as efficient as good old coal, nuclear, and fossil fuel. These two things do not make a good combination for the embracing of more ecologically sound forms of power.

But as you said, small steps to big goals! The best thing about this project is the creativity factor. These are the kinds of guys you want on your engineering team.

You could apply more torque to the system with a longer crank, but you'd have to move the crank further, in direct proportion, to do so. Each crank would require a 15 feet circuit, applying force the whole way. Having a longer lever won't enable you to push harder.

Hey, Olympic caliber athletes can put out about .5 hp, or 370 W. For a couple of minutes, then they throw up. Most fit people are closer to about 70 watts for short periods of time. So, assuming you have awesome power conversion system and are getting close to 100% efficiency, you could power a rather dim lightbulb, for a short period of time. Cool, eh? But not so useful - save your breath, and bike to work. Your car is less than 100% efficient, and extremely heavy, so you're saving ~20,000 W by riding your bike, versus generating 70 W riding a bike connected to a generator.

Dune - Desert Web Power (1)

WillSeattle (239206) | more than 13 years ago | (#142991)

Actually, there's a few tens of thousands of us who go to Burning Man>/a> each year who might find these very useful, since the entire event is held in the desert (on the playa near Black Rock, Nevada). []

And those hand-cranked flashlights are kind of useful there, too.

Maybe this might also have some kind of military application, too ...

Troll? It was a joke! Well, at least two out of three moderators got it (two +1 funny, one -1 troll). Who is the idiot that can't distinguish the difference between a troll and a joke? Oh well, I guess I'd rather have you moderating Slashdot than going out and reproducing... as unlikely as the latter seems.

New Nike webserver... (3)

fmaxwell (249001) | more than 13 years ago | (#142996)

Maybe Nike could create a huge version of this that had a 10-foot long crank. It could then have third-world children lashed to the crank. The children would pull the crank (like dogs on a dog-sled -- but cheaper), to keep the Nike webserver running.

Nike might even be able to do web hosting for so that Kathie Lee could showcase her clothing line on the web.

It wouldn't be hard to build a battery recharging device that runs off barometric pressure or changes in temperature, although it would require a very low voltage device. There are a few very rare "perpetual motion" clocks in history that used this mechanism to get enough energy to tick until their gears wore out (or, more likely, were take apart for various reasons.)

Of course, this device seems to draw a lot more current.

In science museums you'll find exercise bikes hooked up to lightbulbs to show exactly that.

Didn't they have a similar rig in Gilligan's Island? I remember they would run their washing machine and recharge the radio's batteries with an exercise bike.

The Ultimate Use! (2)

MagikSlinger (259969) | more than 13 years ago | (#143001)

Of course! Instead of a web-server, add a peer-to-peer client. Add wireless Ethernet and a Carusoe chip, and you can create the ultimate peer-to-peer network for the third world! Imagine it, paying small children to crank their little P2P stations all day in order to provide free MP3's or find the cure for cancer. It's brilliant. Why didn't I think of this before?

What about boating? (1)

ImaLamer (260199) | more than 13 years ago | (#143002)

Hell, they are just coming to me now!

Lets say you got a wireless thing in your city-you could run this in your car. Connect it to a windmill on your hood or roof (maybe several small ones).

Maybe you have a boat? Using the right gear ratio that wind could be easily used to run this thing. Now just add a monitor or some other low power display and boom! Maybe not a web server, but a client that downloads data about [tides|weather|sunrise/fall|slashdot articles].

This is what we need! Renewable energy computers. Hell, give me a solar panel, a few pentium 100's and we'll crack any task they throw at us - and now black outs.

But I guess that would be the main use. Cali blackout - crank up the web server.

Remember the Apple eMate 300/Freeplay combo? (2)

cryptochrome (303529) | more than 13 years ago | (#143004)

Sorry guys, but you're many moons too late for this to be new - Apple beat you to it in 1996, in the form of the ill-fated eMate 300 [] (incidentally, the first translucent Apple product) coupled to a Freeplay generator [] , for the useful purpose of education and as written in this 1997 press release [] . Furthermore, although the eMate (and it's parent the Newton) are long dead, the idea is still pretty much on the table with Apple, as this 1999 WIRED article [] points out. Who knows, with Apple seemingly interested in getting into the PDA market again, we may yet see this idea resurrected in commercial form.

Long and short of it - screw webservers. Think of powering keyboard-equipped highly functional PDAs with these things.

I saw an episode of the Six Million Dollar Man where Steve was on this old U-Boat (complete with Nazis). The power went out, but LUCKILY there was a hand crank that could be used to power the boat in an emergency. None of the retread Nazis that were on the U-boat could turn it (Presumably, only pure Arians would be able to). Good thing for them Steve Austin was there. He just fired up that ole bionic arm of his and they sailed home in style.

This is pretty obviously a blatant plug by the parent company of BayGen, LNUX, to sell their hand powered flashlights [] . Bet tomorrow we'll see their parallel marketing show up on ThinkGeek. This is the same kind of stuff Viacom does with making Destiny's Child show up on MTV eating Popeye's fried chicken.

The corporate leveraging is everywhere. Don't be fooled, and don't let them tell you what to buy.

I went down at about 50 MPH about 2 weeks ago... came out of it with a sprained wrist

Wow! 50 and only a sprain? That's amazing.

When I had my motorcycle I can remember at least two occasions where a little extra bad luck would have left me either dead or wishing I was.

People make mistakes. People get distracted. It happens. Once that happens it's just a matter of whether or not some other unfortunate thing is happening at the same time (like a driver of a car also being distracted and happening to come at you.)

I happened today to hear Stephen King talking about his accident. He was nearing the crest of a hill when he was suddenly struck by a van coming the other way.

It turns out that the driver of the van had a cooler of meat in the back seat that his dog was trying to get into. He reached back to smack the dog. Stupid, but being distracted in this way he did not realize his van had drifted onto the shoulder just as King happened to be approaching. As the van suddenly appeared at the top of the hill King had no chance, and was flattened and nearly killed.

Had King been in the same place but on a motorcycle the result would have been the same. Had he been in a car with airbags it'd be another story. Same amount of outrageously bad fortune, but he'd have walked away.

You may be the greatest motorcycle rider who ever lived, but you still are giving up some amount of life expectancy to ride that bike.

(By the way, the van was on the road because the driver was heading into town to buy the Mars Bar he was craving.)

ColGraff (454761) | more than 13 years ago | (#143016)

Imagine putting seti@home on one of these lantern computers, along with a wireless modem and Iridium hookup. You wouldn't even need a display, just crank in order to get a few of those oh-so-crucial work units out for Team Whatever. You could distribute these computers in third-world countries, and have massive computing power from millions of people just cranking these things a few minutes at a time.

No, I am not being serious.

Gazelem (460580) | more than 13 years ago | (#143018)

I see a potential use in cases where you can connect to an ISP of some kind via line-of-sight but in an area that is environmentally sensitive such that you don't want to introduce power or where the interference of running power would be harmful to the conditions of an experiment. What this could do is allow a machine to do data sampling and serve it immediately rather than have it uploaded and then served. It essentially takes out a middleman.

The more innovative technologies we can have, the more the inventive minds can implement those technologies is useful and beneficial ways.

Re:Actually... (2)

Gazelem (460580) | more than 13 years ago | (#143019)

Yeah it does and while I agree that by itself it is of limited use, I'm more referring to its potential in underlying technology implementation.

Technology advances in small steps, not giant leaps. Unfortunately, to get to what appears to be those leaps, the small steps in between can often seem rather silly. But if we look beyond things as they exactly are and use something like this to say, "It's not quite right but if I added this one little thing..." then the technology advances.

My major point was that this type of technology has some good use, even if the actually application still has kinks.

I want a fair share. (1)
