Urgent Evoke

A crash course in changing the world.

I was thinking about something I use every day as a student, my desk lamp, and how much of an impact that it has every year. In Canada there are about 1 million tertiary students, and if they study a mere hour a day during the school year that's about 11760 giga watts using 60 watt light bulbs for the year.

I thought it would be amazing to use something that doesn't depend on burning coal or produce too much waste, so I thought why not utilize something biological.

I know though that this idea isn't really feasible since it hasn't been developed, and I'm sure that there will be many challenges in developing a bioluminescent light source, and it's definitely not something that's supposed to replace all lighting since the amount of light that these bulbs could produce right now would be only bright enough to light a desk but not a room.

Basically its a glass sphere that has a mesh filling it to provide a framework for the bacteria to grow on. Nutrient broth or another nutrient source is fed through the top every day and feeds the entire bulb with a small tubing system, the bottom allows the few excess drops to come out.

Different solutions could be used, a first one to inoculate the bulb with the bioluminescent bacteria, solutions to feed the bacteria and solutions to clean out the wh*** system; killing all the bacteria and resetting the bulb.

Hi Rahman! I know you are in my geographic region and I thought you would be interested in this: IKEA sells a solar desk lamp. For every one you buy, they purchase one for students in Africa, so that they can study after dark. http://www.ikea.com/us/en/catalog/products/90154371 My husband just went to the Amazon jungle for 2 weeks and brought one lamp with him there. When he was finished using it at the end of the 2 weeks, he gave it to a villager for his daughter to use.

Lee: thanks for the solar desk tip!

Rahman: I love your idea of a bowl of nutrient broth fueling a bulb of light. Maybe the design would be less like a light bulb and more like a fish bowl? Thanks for this!

I love it. it's the most imaginative idea I've heard here yet.

Fourth of July on the Lake

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

Stinging Nettle

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

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

public servants

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.
