Designers seem to be setting a new trend for solar chargers, turning small scale renewable gadget charging into something resembling a bouquet of flowers. Hot on the heals of the Sunny Flower solar charger concept we showed off in September comes the iPetal, a design strikingly similar, and perhaps establishing a trend for stylish solar.
LivinGreen Materials showed off their drop-in solution to creating more efficient, cheaper solar cells. And their claim is no small number. They say their solution - which would remove one layer from the solar cells currently manufactured and replace it with a layer created by their new technology - could improve efficiency by 50% all while making it cheaper to manufacture solar cells.
Everyone loves a kit, and Soltac has put solar cooking in one tiny bag, creating a product that looks perfect for camping or disaster situations. The all-in-one CookSack looks like a big parabola with a pot in the middle when unfolded, and offers a fast set-up for solar cooking.
It has been a science fiction dream: the completely integrated, closed loop system "micro-farm." And we get it with the Inka Curve, a vertical minifarm that provides herbs, grasses, fruits or vegetables grown on a vertical "bio-quilt."
Sometimes the most impressive products at Greenbuild are the most innocuous and boring looking things; last year I thought the best of show was Agriboard, a SIP made from straw. This year I spent some time trying to figure out this ridge vent for a standard shingled roof with tubes running through it, thinking that there wasn't much surface area on it and it isn't going to do much. Then I realized that all of the heat in an attic runs through the ridge vent and this thing turns your entire roof into a solar collector.
Space Solar Power System Closer to Reality
Japan's space agency, USEF, is in the news again with their plans to build a space solar power station, equivalent to a medium sized nuclear plant, by 2030. Inspired by hope that such a sci-fi vision becomes reality, we have some advice for the Japanese space agency, some wisdom learned in the trenches of the fight against global warming. The nugget of knowledge that could make the difference between success and failure for the ambitious space-based solar station is this:
Only the other week I posted about an innovative project to integrate solar power with food production, and while the photo-shopped graphics for that post may have left something to be desired, a new installation may give a better idea of what's possible. In what's billed as the "first, cable-suspended free span solar energy system"REM eyewear and P4P Energy have created a patented system that could help expand the potential for integrating solar with other types of land use.

There's often something left to be desired when it comes to the styles of solar bags. Many are simply ugly, though quite a few also make it into the realm of hip. This bag falls somewhere in between, bordering on ugly if it didn't do such a great job of stating the obvious via a massive solar cell on the front flap - "This Bag Is Solar Powered!!" It's the Energy Sun-Bag from Neuber and Konarka Technologies....
If I didn't already have a solar bag from Voltaic, I'd be so jealous right now. Attendees at this year's PopTech received as their swag bag the FLAP - Flexible Light and Power. It's messenger bag with built in flexible solar cells that can charge up a mobile device, or power an LED in the bag, turning it into a lantern. It certainly sets a new standard for swag bags at events. How great is it to offer attendees not only a cool bag, but off grid charging capabilities too?! Check out how neat this bag is - it's far more than just fancy swag, it's a solution for off-grid lighting for impoverished people.

Imagine a free solar array for your home, combined with a full eco-makeover to eliminate draughts, improve comfort, efficiency and air quality. That's the prize on offer to green minded UK householders right now. It's just one part of the 10:10 Campaign's call to cut UK carbon emissions by 10% by 2010. (See also their search for the Voice of Green Britain.) So what do you have to do to qualify? ...

The sleek design of the Regen ReNu offers customers a solar panel charger, that looks like well a solar panel, but also looks like it would blend into the background of a modern, chic, loft apartment. Styled similar to many iProduct docking stations, the Regen ReNu can recharge a variety of electronic gadgets and get several charges off of one battery. But will it be available in time for the holiday rush?...
Park In the Shade, Recharge Your Plug-In Vehicle
Dell's headquarters in Round Rock, Texas, now have a shaded solar parking structure called the Solar Grove. It was built by Envision Solar, and it has a capacity of 130 kilowatts, which should help avoid about 145,000 pounds of greenhouse gas emissions per year. But the clean electricity is only part of the benefit; there's also some energy savings that come from the shade produced by the "solar trees" since cooler cars don't need as much A/C....

From a 25-megawatt photovoltaic plant in Florida to a 4,500 acre solar thermal installation in California, solar just keeps getting bigger. Within that context, a 100kw array may seem hardly worth mentioning, but folks in my community are excited, and not without reason. (Disclaimer alert: Friends of mine are involved with this project.)You see traditionally, unlike wind, large-scale solar has often meant displacing otherwise productive land, to the point where some areas like Ontario are looking at banning solar from class "a" and class "b" farmland. What sets this project apart is that it aims to not just co-exist with productive farm land, but actually enhance the agricultural process. ...

It's about time we see a piece of solar clothing that you'll want to wear. The Zegna Ecotech Solar Jacket looks slick, stylish, has a good cut, inconspicuous solar cells that (almost) don't look like a bad reference to the 80s. And, it's made from recycled plastic! ...
Recycled plastic can be turned into just about anything these days, and while it still gets a bad rep as a green product, now it's being produced with the help of solar power, making it just a little bit greener. In what is the largest construction of a thin film cylindrical solar system, Plastic Package Inc wants to make some of the greenest recycled plastic products on the market. ...

The Source Of The Myth
This myth recently surfaced in the sequel to Freakanomics, call Superfreakanomics. Some people are very disappointed with the authors, who created quite a stir with their first book. The source of the myth is a quote by Nathan Myhrvold, the former Chief Technology Officer of Microsoft (commenting outside of his expertise):...
Is this a scene from the future? Nope, it's happening now....in Germany. Image via: tristam_sparks on Flickr.com
In a four-part series by Der Spiegel, the paper explains how Germany is taking charge of the future energy revolution and it is all happening today. From mega projects like smart grids and deserts covered in lakes of solar panels, to the smaller house-hold projects like cutting edge appliances and mini-power plants in every basement, Germany is taking this whole efficient energy production idea very seriously, and as The Environment Report reports, they have managed to cut their carbon emissions 23% since 1990 by supporting and taking a chance on many of these ideas. While American energy markets are almost fearful of what that knowledge might mean, preferring to not allow consumers to have any idea even how much electricity they are using from day to day. Germany on the other hand is putting all of the power back in the hands of the consumer and allowing them to produce their own electricity and make an extra buck or two if they are proactive enough....

The world's largest solar-powered footbridge has now opened in Brisbane. The panels not only power its LED lighting but they also feed the main grid: this will save 38 tons of CO2 annually!
Connecting South Brisbane and the city center, it's expected about 36,000 people will use the new Kurilpa Bridge every week to walk or bike across the Brisbane River. A must have as 1,500 people move into South East Queensland every week! Brisbane is in fact the fastest growing urban region in Australia.

A solar powered DJ booth (see photo below), tree seedlings from Hiroshima, a Human Glacier performance and Yoko Ono - all of this is happening under the High Line in New York this month. The Drop and exhibition 2012+ is about art, the city and the environment. Its title is inspired by the Mayan calendar, indicating an upcoming shift from one phase of life to something new about to take shape. Here is how the curators, Alexandra Chang and Mie Iwatsuki, explain their concept:...

If you thought there were water wars brewing before, just wait. The sun is often touted as a fantastic source of energy, which it is, but there's a hitch: Many solar projects consume enormous amounts of water. How much water are we talking? According to a recent New York Times article, proposed plans for two solar farms in Nevada would gulp up 1.3 billion gallons of water annually--or 20 percent of the area's available water. And the worst thing is this heavy water use in renewable energy projects is all about the bottom line....

Sempra doesn't know yet if it's going to be solar PV or solar thermal, or a combination of both. ...
