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.

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.

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

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.

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.

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.

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.

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. A pulley works the same way - to pick up something twice as heavy, you pull the rope twice as far.

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.)
