Clear material on windows harvests solar energy
A new type of “transparent” solar concentrator can be used on windows or mobile devices to harvest solar energy without obscuring the view. Past efforts to create similar materials have been disappointing, with inefficient energy production or highly colored materials. “No one wants to sit behind colored glass,” says Richard Lunt, an assistant professor of chemical engineering and materials science at Michigan State University. “It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent.” The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. “We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared,” he says. The “glowing” infrared light is guided to the edge of the plastic, where it is converted to electricity by thin strips of photovoltaic solar cells. “Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye,” Lunt says.

Researchers at the University of California San Diego have designed an electronic tattoo—a small, flexible circuit board that can be worn just like the Spiderman temp tats I used to stick on my face—that produces an electrical current.
It works by stripping the electrons from lactate, a byproduct of sweat, with an enzyme imprinted on the e-tattoo’s sensor. In other words, it produces power from your nasty workout juice. And, the researchers say, the technology could eventually generate enough electricity to run devices like phones, smart watches, and heart monitors.
"These represent the first examples of epidermal electrochemical biosensing and biofuel cells that could potentially be used for a wide range of future applications," said research lab director Joseph Wang in a statement.
When spoken word artist Brenna Twohy tells you that she is an unabashed devotee of all things “Potterotica” — erotic fiction based in the magical universe of Harry Potter — your response probably shouldn’t be that her taste is “unrealistic.”
I’m happy to be getting to the point where I don’t have to feel weird about enjoying fanfiction, or having written a bunch of it. Partly it’s that the fandom experience has become more broadly shared. Partly it’s that I stopped giving a shit.
And as for why I like the porny sort of fanfiction, see above. She says it better.
I like sex with context. I like sex when it involves fully fleshed out characters. I like the backstories. I like feeling like these people do other things when they aren’t having sex.
"I’m an inveterate cannabis user, and I wish in a way that I could get a slightly better grip on my cannabis use, because I think the real way to do cannabis is like once a week, by yourself, in silen…
I found this really interesting, my view is similar to Terence’s where i feel it does lift the veil between the unconscious and the conscious minds, it’s also a chakra cleanser in many respects because you will notice your thought patterns shift towards what you need to work on with yourself or maybe you just need to relax. Anyway felt like sharing since i’m sure many of us use Cannabis
Spray-on solar cells take less energy to make and can be put on everything from jeans to cars.
Scientists are one step closer to spray-on solar power. Instead of traditional bulky solar cells encased in glass—which can be awkward to put in places other than a roof, and take a lot of energy to produce—we may someday be able to easily spray paint low-cost, low-energy solar cells on everything from a pair of jeans, to a car, to the side of a skyscraper.
If you use YouTube, you need to know this.
You’ve heard all these rumblings about Net Neutrality over the past several months. Let’s get real: this is about controlling online video. It is estimated that by 2017, video content will account for 80-90% of all global Internet traffic.
This isn’t just about not being able to binge-watch a series on Netflix. It’s about the future of online video as we know it.
Whether your YouTube channel is home to daily vlogs, short films, or just that one video from when the cinnamon challenge seemed like a good idea, you’re a video creator. Your content and comments help shape this community. Let’s keep it that way.
Net Neutrality means that your YouTube videos reach people at the same speed as clips from last night’s episode of the Tonight Show. It means a level playing field for video creators looking to reach an audience. But new Net Neutrality rules could mess that up.
Here’s the deal: Telecommunications companies already charge us to access the Internet through our homes and our phones. New FCC rules could allow them to also charge content providers (like YouTube, Netflix, and even PBS) for access to our eyeballs. It could create a fast lane for Jimmy Fallon’s clips, and slow lane for your YouTube videos.
It is really important that the FCC understands that online video creators care about Net Neutrality. Even if you’ve only ever uploaded ONE VIDEO, you are a creator and you have a voice.
If you can, please add your channel to our petition. We’ll deliver this to the FCC in September and demonstrate that the online video community cares about this issue.
