AN umbrella that lights up?
So here's an innovation: An umbrella that takes the kinetic energy from raindrops hitting a conductive membrane
called PDVF and transforms that energy into electrical energy powering embedded LEDs.
1. Rain
2. PDVF membrane
gives 3. electrical energy.
Sang-Kyun Park has created a pretty awesome way to navigate a rainy night, but I can see a wider potential application, if the size of the membrane could be increased and fitted any where (or kept in a mobile state) can we not generate electricity to be used for anything, not just LEDs?
Without being of a scientific mind and having the actual article in front of me, it is hard to say, but it certainly seems like there is the possibility to expand on this idea.
Here is a wikipedia primer on PDVF: key points to note might include it's "relative low cost" and applications such as "piping products, sheet, tubing, films, plate" and even more interestingly - as a paint! Could a roof be made of/coated with a membrane of this sort?
This page says the highest average rainfall is in Hawaii... I'd volunteer to scope out the scene there any day!

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
The meal
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. I walk to the fridge and open it to see what there is for me to eat.

Foods are vacc** sealded for easy…See More
Future
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.
