Sustainable Design Update

via Jetson Green; posted by Matt Grocoff

In the very near future, expect to be able to control devices, appliances, and lights in your home with the help of Google. That’s the information coming out of Google’s developer conference, Google I/O, where Android@Home was first announced. With the right app, an Android-powered smart device, and an intelligent LED replacement bulb from Lighting Science Group, a savvy homeowner could geek out a home without much effort.

One exciting new entrant into the LED market is the Panasonic “Filament” LED.  It’s designed to look like a traditional filament light bulb but uses only a tiny, tiny fraction of the energy.  It won the 2011 Good Design Gold Award at this year’s Good Design Award show hosted by the Japan Institute of Design Promotion.

It’s a traditional screw in bulb, uses only 4.4 watts (almost 80% less than it’s incandescent counterpart), and it has a soft, warm glow (for you lighting geeks . . . that’s a 2700 kelvin light temperature).

I think I’ll soon have to write an obituary for the CFL.  As my good friend Michael Klement says “CFL’s are the 8-track tape of the lighting world.”

The 100th Object - British Museum

It took curators four years put together the British Museum’s blockbuster exhibit “A History of the World in 100 Objects,” an attempt to tell the history of the world through objects pulled from the Museum’s huge collections.  The result:  a four hour BBC Radio show + book of the same name, soon to be published in the U.S.

Choosing the 100^th object we find was difficult and long debated.  In the end the curators chose a humble solar home lighting system for people who don’t have access to electricity.

As many SDU readers know we have been working on a home solar lighting system that can be assembled in the country where it is to be used.

Solar Home Lighting System

In 2008 an international research and development team lead by the Appropriate Technology Collaborative was awarded a grant by the Lindbergh Foundation in order to work with our partners in Guatemala and Nicaragua to build and evaluate various designs for LED lights that are superior in performance to the kerosene lamps widely in use in those low income countries today.  Energy efficient LED lights are both safer and more affordable than kerosene lighting.

The Appropriate Technology Collaborative will be working with engineers and educators in Guatemala to teach local tech school students how to design and install home lighting systems in February and March 2012.  We will have updates from the field.  Stay tuned.

Soaking in a hot tub after a walk around one of the most beautiful lakes in America. Relaxing by the fire after a fine meal downtown. Slipping between soft sheets at the end of a perfect day. Welcome to your next “green” vacation.

This exceptionally ambitious venture boasts solar, wind, geothermal and an aerobic mound system.   Fritz Kreiss and his wife, Catherine McQueen are the creators of The Green Leaf Inn located in Delavan, Wisconsin and will have 19 luxurious rooms.  The 50kW wind turbine will help produce as much energy as the hotel’s occupants consume.  This may be the first hotel in North America to achieve net-zero energy.

A couple years ago when I launched Greenovation.TV I posted a video from Brazil about a creative hack to turn soda bottles filled with water into 50 watt equivalent lights. After 700,000 hits on that video, I just found another cool BBC video about a similar use of these inexpensive sun tunnels.

A simple initiative in the Philippines is bringing a bit of brightness into the lives of the country’s poorest people.  The project is called “Litre of Light”, and the technology involved is just a plastic bottle filled with water.  It’s an environmentally-friendly alternative to an electric light bulb, and it’s virtually free.

Game over. LEDs win. Early in 2011 I wrote about the rapid ramp up of high-quality LED bulbs. Shortly afterwards, the big box stores started selling absolutely flawless bulbs at the eye-popping cost of $39.95. Even at that price the life-cycle payback still beat the old school incandescent bulbs for total cost. The problem was that it was about an 18 year break even.

That didn’t keep customers from grabbing these bulbs off the shelf. One big box store I visited said they were having a hard time keeping the LED bulbs in stock.

Now you can walk into a big box store and get a Philips Endura LED that uses only 12 watts for only $24.95. Today I was giddy over the sudden price plummet of these bulbs. You haven’t seen this kind of joy except from little Japanese girls finding Hello Kitty hats on sale. Please don’t judge me.

This is a game changer in lighting. Here’s why . . .
