Ingenuity can go a long way in meeting people’s essential needs with the simplest of materials.

The recipe: Start with students from the Massachusetts Institute of Technology (MIT), add basic materials destined for dumps and landfills around the world, mix with filtered water and bleach, install, expose to sunlight. And voilà!–a light that will last for 10 years!

The Solar Bottle Bulb is based on the principles of Appropriate Technologies – a concept that provides simple and easily replicable technologies that address basic needs in developing communities.

Networking for Artists?

The CEO of a well-known company sent me a message on LinkedIn. He said that he knows lots of artists, who would all like to network and why don’t I start such a thing… Well, why not!

I shall look for every visual artist I can find on WordPress and follow them and pray that they do the same. There must be quite a number of us on this platform. Let’s mix, let’s mingle, let’s art-network! You never know where this might lead…

Let me start by introducing myself: I am Reginald Van Langenhove, from Belgium. Also known under my pen name Ralphie A Burcke, from I have not yet been able to make a living with my art, but I consider myself an artist, because I live and breathe art and will continue to do so till I die. Please to meet you!

How to build a Scottish Blackhouse.

From Natural Homes:


This is the blackhouse at Arnol, Lewis, Scotland. It’s one of the few blackhouses that survive in the settlement which saw the demise of blackhouses, which were then called taighean (‘houses’), when people were moved to stone and lime mortar homes that were refered to as whitehouses. This blackhouse was built in 1880 and was occupied until 1966.

10 Ways to Go Green and Save Green.



How can we live lightly on the Earth and save money at the same time? Staff members at the Worldwatch Institute, a global environmental organization, share ideas on how to GO GREEN and SAVE GREEN at home and at work. 

Climate change is in the news. It seems like everyone’s “going green.” We’re glad you want to take action, too. Luckily, many of the steps we can take to stop climate change can make our lives better. Our grandchildren-and their children-will thank us for living more sustainably. Let’s start now.

We’ve partnered with the Million Car Carbon Campaign to help you find ways to save energy and reduce your carbon footprint. This campaign is uniting conscious consumers around the world to prevent the emissions-equivalent of 1 million cars from entering the atmosphere each year.

Keep reading for 10 simple things you can do today to help reduce your environmental impact, save money, and live a happier, healthier life. For more advice, purchase State of the World 2010 – Transforming Cultures: From Consumerism to Sustainability, a report from 60 renowned researchers and practitioners on how to reorient cultures toward sustainability.

  1. Save energy to save money.
    Set your thermostat a few degrees lower in the winter and a few degrees higher in the summer to save on heating and cooling costs.
    • Install compact fluorescent light bulbs (CFLs) when your older incandescent bulbs burn out.
    • Unplug appliances when you’re not using them. Or, use a “smart” power strip that senses when appliances are off and cuts “phantom” or “vampire” energy use.
    • Wash clothes in cold water whenever possible. As much as 85 percent of the energy used to machine-wash clothes goes to heating the water.
    • Use a drying rack or clothesline to save the energy otherwise used during machine drying.
  2. Save water to save money.
    • Take shorter showers to reduce water use. This will lower your water and heating bills too.
    • Install a low-flow showerhead. They don’t cost much, and the water and energy savings can quickly pay back your investment.
    • Make sure you have a faucet aerator on each faucet. These inexpensive appliances conserve heat and water, while keeping water pressure high.
    • Plant drought-tolerant native plants in your garden. Many plants need minimal watering. Find out which occur naturally in your area.


  3. Less gas = more money (and better health!).
    • Walk or bike to work. This saves on gas and parking costs while improving your cardiovascular health and reducing your risk of obesity.
    • Consider telecommuting if you live far from your work. Or move closer. Even if this means paying more rent, it could save you money in the long term.
    • Lobby your local government to increase spending on sidewalks and bike lanes. With little cost, these improvements can pay huge dividends in bettering your health and reducing traffic.


  4. Eat smart.


  5. Skip the bottled water.
    Use a water filter to purify tap water instead of buying bottled water. Not only is bottled water expensive, but it generates large amounts of container waste.
    • Bring a reusable water bottle, preferably aluminum rather than plastic, with you when traveling or at work.
    • Check out this short article for the latest on bottled water trends.

How Your Old CDs Can Turn Sewage Into Drinking Water.

Magnificent new idea, copied from


Taiwanese researchers have made a breakthrough in wastewater treatment, but will anyone actually drink it?

Good news, fans of terrible 90s bands—your unhealthy obsession with Hanson, Sugar Ray, or Creed could turn out to have a happy ending. No, their music will never be palatable, but the actual CDs on which their tunes were laser-printed, the very same audio discs currently collecting dust in your mom’s basement, could be used to make dirty water potable. At least this is the potential new use for old CDs recently proposed by a team of Taiwanese researchers.

“Optical disks are cheap and readily available,” said lead researcher Din Ping Tsai, a physicist at National Taiwan University, in a press release. “Close to 20 billion disks are already manufactured annually, so using old disks for water treatment might even be a way to cut down on waste.”

Each month, roughly 100,000 pounds of CDs become obsolete, with millions being sent to landfills around the world. When a CD decomposes, it releases Bisphenol-A, a toxic chemical that’s been linked to brain impairments, cancer and more.

Tsai’s process involves using a CD’s flat surface as a platform on which to grow zinc oxide. Later, when illuminated with UV light in a prototype water treatment device, the zinc oxide acts a photo-catalyst, breaking down organic pollutants in sewage water that’s filtered in by a hose.

In a test, the researchers found that “over 95 percent of the contaminants had broken down after just 60 minutes. That’s about 150 ml of waste water per minute.” For comparison, a typical bottle of water contains 500 milliliters.

Calling All Art-lovers.

There may be some outstanding artists in your very neighbourhood, who are barely making a living with their art, because most people content themselves with buying a reproduction of a famous artwork. Why not buy a real, unique piece of art from a contemporary artist? Think it over!
