For two days in October 2011, SEED and the Schlumberger Museum of Crevecoeur Foundation participated in the French national event “Fête de la Sciences” (Festival of Sciences) at Caen, France.
SEED has been collaborating with the museum for five years. Together, we have participated in “Fete de la Sciences” four times.
During the 2-days sciences expo, I joined museum staff Christophe, Florence, and Nathalie to welcome the public at a SEED and Museum science booth.

Hello Seed Community!
Why have hydrogen powered cars not been developed further? Or not already on the market?

The 11th minute of the 11th hour of the 11th day of the 11th month of the 11th year of the 21st century. How often can we have a moment like this is our lifetimes?!
I am 22 years old, and about a week ago I slipped and fell on my left elbow. It was my first fall in a long time ago. My arm was hurting, but I thought that I had fallen when I was younger and everything was fine, so it would be fine this time too. But the following night my arm became very swollen and it hurt to bend or stretch my arm. In a few days the pain got better, but I still had trouble stretching my arm or picking things up, so I went to see a doctor.
In a few short years compact fluorescent light bulbs have gone from “what’s that weird twisty bulb thing?” to bulbs that are readily available and routinely used. Although the bulbs themselves cost more upfront than incandescents, they save money -upwards of $30 per bulb- because they use less energy and last longer than traditional incandescents. The bulbs themselves have also improved—with more natural-looking light, and the same features as incandescent bulbs, such as three-way capability, and compatibility with dimmer switches. We have all been encouraged to switch to CFLs. Incandescent bulbs will be phased out by 2012 in the United States.
However, in order to get the most out of these bulbs and use them most efficiently, there are some things you should know.
1. Most important is to know how CFLs, and traditional fluorescents for that matter, wear out. The number of times you flip the light switch contributes to the life of a fluorescent bulb. The starter wears out, so the more times a fluorescent light gets turned off and on, the shorter the lifespan of its bulb. So, what does this mean for CFLs? Well, they function best when installed in places where they will stay on for at least 20 minutes at a time, if not more. I originally put one in my utility closet, but once I realized the role of the starter, I switched back to an incandescent bulb for that spot. I then put CFLs in the fixture over my bathroom vanity, my office, and my kitchen, locations where lights stay on for a long time.
This year has been an odd year. I have had some horrible low points and I had some of my dreams fulfilled.
Fruit Power in Bolivia!
We have been organizing our very first Seed Workshop in Escuela Flamingo, Santa Cruz, Bolivia after the school re-grant, it´s the Fruit Power!! On Wednesday, Nov 09th we will have around 100 students learning a little bit more about science and energy!!
Thank all volunteers and teachers involved in this beautiful project!
Hope all goes well!
