Saul Griffith dreams of giant kite turbines creating huge amounts of
clean, renewable energy.
Wind is the second largest renewable resource after solar. But the majority of wind power is in high altitudes, well above 300 feet - beyond the reach of today's wind turbines. We don't have a technology (yet) capable of tapping into this rich source of wind energy.
This idea was described by Miles L. Loyd in his paper "Crosswind Kite Power". He… Continue
My everyday wish list includes a shower head that not only saves water (this is common) - but has a "pause" button.
You could stop the water flow at any time (e.g., while shampooing your hair) and then restart the water flow -- at the same temperature.
Some people suggest you turn a shower on and off while you're using it, to save water. If you're fortunate to live where water supply is not an issue, that sudden blast of cold water (while the temperature readjusts) prevents… Continue
Scenario: A pandemic flu reaches my part of the world in the 2011.
I would organize "opinion leaders" from many diverse groups to spread the message online. Individuals would be chosen based on their demonstrated commitment to serving the social good, not celebrity status.
The goal is to reach as many people as possible, and spread reliable information about the pandemic flu - including the URL of a "dark site".
This group of opinion leaders would be diverse and… Continue

It's curious how we can influence and inspire others - without even trying.
When you act true to your deepest values or pursue an undertaking with total commitment, people tend to stop and notice. Chances are you don't realize what's happening because you're so immersed in what you're doing.
You're doing something special. Your actions may impart a lesson that is remembered - long after you are forgotten. And that's okay.
Sometimes you try to influence or help a… Continue
How do you find water in the desert, arid climates, and future deserts (desertification)?
Ancient wells (khettaras) in Morocco:
An ancient solution to creating a reliable water supply in the desert was developed in Iran more than 3,000 years ago. Qanats are man-made subterranean tunnels that lead groundwater to the surface for irrigation. Today these wells are found in the… Continue
This is not a disaster. But when the public transit system (especially the subway) breaks down, parts of my city grind to a halt. The transit system backs up quickly. People are stranded on street, or face a long walk to their destination.
Who is most affected by transit breakdowns in my city?
People who rely on the subway or buses to get to work or school.
People on a fixed income who need affordable transportation.
How can poor farmers grow their crops using less water and fertilizer?
Drip irrigation (also: trickle irrigation or micro-irrigation) saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of values pipes, tubing and emitters.
I first read about drip irrigation in the book "The Blue Sweater: Bridging the Gap between Rich and Poor in an Interconnected World". It… Continue
I'm a long-time supporter of FoodShare in Toronto, Canada. While food banks are necessary, organizations like FoodShare empower people through education, grassroots efforts, and smart local economics. Their wholistic approach looks at the entire food system - how food is produced, distributed and consumed.
Some of FoodShare's initiatives:
Good Food Box - People buy boxes of fresh, healthy foods at cost from local…
The Field-to-Table program is a not-for-profit healthy food delivery system for Toronto’s low-income citizens, operated by FoodShare since 1992. It's a smart wholistic approach to food distribution that is community-based and market-driven in a way that supports local farmers.
In an ideal world, we could convert our physical activity (walking, running, exercising, etc.) into stored energy. Gym equipment would have energy storage cells. Also, wind energy passing through (electric) cars and transportation vehicles would be captured and converted.
Healthier active people. Clean(er) renewable energy.
"I love that you've brought this to attention. An extensive database of uncommon but resistant and hardy plants/foods could be developed and organized by climate. Ease of growth and processing should also be taken in to account. I will try to…"
This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More
It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal.

Foods are vacc** sealded for easy…See More
FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
