Printable Batteries Should Arrive Next Year 92
FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Now we can have an unlimited supply of electrical energy. Just keep photocopying the batteries!

Now we can have cards with OLED displays that can show a message delived by you in person, via a video! Quite cool, I think.

So, you can record "I hate you, you fucking bitch" on a greeting card, and it plays the first time she opens it, then the battery runs out and the audio is lost, so she can't get a restraining order based on it...

I just want to know if these batteries will be available as a PDF so I can print my own.

Could we put it in an endless loop so it keeps printing over the battery that it just drained to print the battery it uses to print?

That's genius! Then we would use the heat from the photocopier to power other stuff...

Excellent idea, while copying the batteries, we could tell complicated jokes and harvest the wind energy when someone misses it!

Yes, and HP will sell you battery ink in cartridges for $2200.00 per gallon, just like regular ink jet ink.

No, they will be available as a PDF to _prevent_ you from printing your own.

I did something REALLY stupid when I was about 10 years old. I knew enough about parallel vs. series battery piles to be dangerous. Did you ever lick a 9V battery to see if it was good? If you got a really painful sting, it was good, and if it didn't hurt, it was probably too dead to run the game? Well, have you ever tried connecting 20 of those in series, making a pigtail and licking the conductors to see if it worked? I did. I learned a very quick lesson about that. I saw a flash of light and was dazed for a little while. I'm embarrassed to admit that here, but hey, I was only about 10 years old. Yep, I've always been a bit of a geek like that. That year I learned a lot of lessons: why a lot of batteries wired in series can be as dangerous as mains (my first mishap with electricity was when I was about five years old where the batteries in my pinball machine went dead so I made a cord to plug it into the mains - I fried both the outlet and the pinball machine internals), I learned why one should check the flyback circuit cables to make sure there is NO dry rot when working on internals a live (CRT) TV (or end up with a numb arm if there is a crack in the line and the screwdriver goes near it), why a magneto on a motorbike engine should not be played with while it's running. Those lessons were painful! :-D

Laser printers, meboy! Sure the toner costs $100 for a replacement cartridge, but you can print 5,000 pages with one of 'em. And as a plus, it's got a laser in it! Quiet, fast, cheap...all made possible with the humble laser. Inkjet printers rightfully should be dumped into a hole in the ground.
