Paper Solar Panels? Who Says Solar Power Isn’t Portable?

Paper Solar Panels? Who Says Solar Power Isn't Portable? | 40Tech

I have to say, I’m loving Google+’s Sparks for the interesting stories I find there. Today’s gem comes via the L.A. Times blog, and is something our good friend Josh Farkas would be proud of. During Josh’s short stint as a writer for 40Tech (until life got in the way), he piqued my interest in the wonders of modern green technologies — and this latest innovation is a wonder, indeed.

Solar panels are classically big, bulky, glass things that are unwieldy and don’t produce enough power to run anything significant. The technology has come a long way, in recent years, and can now be had as a film, crystalline silicon, a nano-particle spray, and even transparent plastic. However, the methods for creating these solar power solutions are generally expensive, and not all that environmentally friendly. True, mass-production of paper solar panels may not be the best think for trees, but the “ink” that contains all of the solar goodness can print solar power onto tracing paper, newspaper (with printing still on it), tissue paper, and pretty much any other kind of paper as long as it is plain and untreated.

According to the article, the process is similar to the way the “shiny interior of potato chip bags” is created, and is not actually that far off from inkjet printing — except, you know… it’s printing solar cells. A regular-sized sheet of paper can power small electronics like LCD clock displays and the like, and the solar cells are created from “common elements” which are more friendly to the environment and allow for a cheaper, more sustainable way to generate power.

One of the most interesting aspects of this solar paper is the portability of it. It’s a piece of paper — you can tape it up, keep it in your binder or notepad, and it can even be made into clothing. Basically, it can go wherever paper can go — and that also means in your pocketses. Even if you fold it into a paper airplane, it will still work when you flatten it out again. Oh, and if you’re worried about the practicality of the paper in the face of things like rain, believe it or not, you can laminate it too.

Unfortunately, this new solar tech isn’t ready for sale at the moment, but the bright fellows over at MIT who created it are busily improving on it so we can all have our very own awesome paper solar panels in the near future. Hopefully, they will get it working with significant power output on recycled paper, or more types of paper ready for recycling, as it will then also help us reduce waste and maybe even save a few trees. I like solar power and its potential — but I like oxygen even more.

Check out the video, below, to see that the paper solar panel still works even after being subjected to multiple folds:

Spray-on Solar Power, Printers That Make Buildings & Generating Power While We Walk

Spray-on Solar Power, Printers That Make Buildings & Generating Power While We Walk | 40Tech

Green tech isn’t waiting on the sidelines while the rest of the tech world progresses. Innovations are happening daily as scientists and visionaries search for ways to tap cleaner, sustainable energy sources. Some of the things that are coming out of those big, green-focused brains are nothing short of amazing, and the folks over at Inhabitat.com have put together a list of inspiring examples. Check out the highlights below:

  • Remember when solar panels were big, ugly… panels? Well, now there is a transparent nano-particle spray that can generate energy across the surface area of an entire building — or the top of a car, or most anything else.
  • Freaked out at the cost of building materials? There’s a 3D printer in development that can print entire stone buildings out of sand — at less cost and with less waste than Portland cement.
  • What do you think about floor titles that convert the kinetic energy you expend walking into useable energy? Wouldn’t that be a neat way to power a subway system? What about mini-generators in the soles of your shoes? You know, to charge your cell phone or power some blinky lights while you run?

Me? I think this all sounds very, very cool. My one concern would be the energy needs and waste that would result from mass production of this kind of tech. After all, if you kill 10 fish in a pond just to catch one with a “humane” hook — next season will be rather slow, yes?  (* /metaphorical-wisdom *)

A Car That Runs on Your Own Poo

08.10.10 - Gas pump

So you’d like to improve gas mileage because you’ve got a 100 mile round trip commute, gas isn’t getting any cheaper, or you just want to put out less CO2?  Whatever your reasons, there are tons of hybrid and electric choices, and new offerings all the time.  But with any new technology, there is what I will refer to as “hype,” and cars are no exception. 

If you think that there is too much “hype” around these electric and hybrid vehicles, then we have found the technology for you!  On Monday, Volkswagen premiered the “Bio-Bug” which will run on human sewage or some of that…”hype.”  Discovery News’ tech blog is referring to it as a poo-powered Beetle.  Let the jokes begin; I would think something about a dung beetle is fertile ground for comment.

Would you consider owning a hybrid / electric / sewage fueled car?  Do you already?  If so what do you think?

Green Tech to Save Some Green: A New Monthly Column

Green Tech to Save Some Green | 40Tech

Short of spending $18 billion of your hard earned cash on speculative research, there are things that each us can do to reduce our impact on the environment.  Yes, you can walk to work and stop using toilet paper, and those are certainly admirable and possibly uncomfortable efforts if combined, but let's be practical: most of us just aren't going to do that. So we wanted to take today to announce that 40tech will be starting a monthly column on environmental technology. We’re calling it Green Tech to Save Some Green. But wait! Didn’t we just say something about $18 BILLION on speculative research? Ohhh yes! Read on!
