A crash course in changing the world.

ACT 3 Using alternative forms of energy. BE PEEPARED

This was not my idea but i feel the need for a little humor and silliness to add to the amazing ideas that people have.

Scientists around the world are clamoring to design inexpensive biochips to quickly test for a variety of
diseases. But no one has been able to make a similarly small and
power source.

Lee and his team of researchers at Singapore's Institute of Bioengineering and Nanotechnology have
tackled this problem by using the very substance being tested - urine -
power the test.

To make the battery, Lee and his team soaked a piece of paper in copper chloride and then sandwiched it
between strips of magnesium and copper. Then they laminated the credit
card-sized unit between transparent plastic films.

When a drop of urine is added to the copper chloride paper, a chemical reaction takes place and produces electricity, which is harnessed by the battery. A few drops
generate about 1.5 volts, the same as a AA battery.
The battery needs to be developed further to make it commercially

"Our urine-activated battery would be integrated into biochip systems for healthcare diagnostic
applications," Lee said.

Lee and his team also found that they could alter the battery's performance - voltage, power, or duration -
by adjusting the design or materials.

The chemical composition of urine indicates a person's general health and is widely used in diagnostic
tests. For instance, doctors measure the concentration of the sugar
glucose to
determine whether someone is diabetic.

Lee predicts that one day people will be able to monitor their own health at home using biochips powered
by this type of battery.

"These fully-integrated biochip systems have a huge market potential," Lee said.

Wow I just had to share this whereever I had access ... facebook, twitter, Bushcraft USA ... just .... WOW!

Reading further via links ... the tech is really here NOW!!!! The batteries are can be powered by any liquid! Water, beer, blood, cola! Anything!

i really like the ideas that involve recycling waste; we all produce so much waste every day. kudos!

this is really cool sunny
Comment by Michele Baron on April 23, 2010 at 11:18pm
very cool. Made batteries with potatoes for my little guys--was told lemons worked, and thought of branching out. I am not sure I will tell my two little boys and littler girl (well, she isn't a problem this way yet...) about this one until they are a bit older and less literal-minded --or maybe just with water or something... lol... thanks for the post

Brilliant great post :) keep up the good work!

Thanks guys, you know when I share these ideas with most of the people I know they just shake their heads at me!

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.

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.
