Urgent Evoke

A crash course in changing the world.

Here's a very quick Photoshop image I made as a concept design. It's basically quite a simple idea: using the extra space on rooftops to grow vegetables. What better way of increasing our food security than start growing our own crops. If low energy heating systems are installed the greenhouse could work during the cold seasons as well, if the vegetables grown can grow at cold temperatures such as 10 degrees Celsius.

interesting - how would rooftop gardening work in for instance scandinavia during the winter? as the current winter has shown us - a global warming can well result in a local cooling during winter in scandinavia. do you have any links to case studies of this? i havent found any - i was thinking of something similar last week

Actually this was just an idea I had of the top of my head. I haven't found any case studies either, maybe it's a dead end since it might be to cold, or someone just hasn't thought about it. The problems probably boils down to the temperature aspect. Which is the lowest temperature the crops can grow in, and if heating is required, is it a net gain? Anyway it might be worth looking into.

agreed. i am sure Sweden has a university or college / högskola which has studies related to this. some professor sure knows something about this. i will try find out who it is at the college at Ås outside Oslo who knows about this, and refer them to this post by you and ask them what they think. feasible?
lets bring on the experts.
lets not waste too much time re-inventing the wheel, but rather work on innovation further from Current best practice, or on Implementation projects!

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.
