Urgent Evoke

A crash course in changing the world.

Heres the thing. We have a stationary bike at home and it has a digital display so it needs electricity and so does the system, which controls the difficulty of your training. So in order to get the display and the difficulty control up and running, you need batteries. My thought is, why not make the bike produce energy for itself? Oh, wait, there are such bikes, Ive seen them in fitness studios. Apparently, the fitness studio owners know a lot about paying as little as they can for the energy, they dont have to. So instead of stationary bikes, that need batteries, they bought bikes, which convert the mechanic energy generated during the workout into electricity to power themselves.

Lets take it further. I suspect, that there is still much more energy being produced in the standard work out session, than is needed for the little display and the difficulty control. Why not include USB connectors in the bike, so that you can plug in your MP3 player, to charge it, while you work out. Or other small appliences. Or you could have a built in standard battery charger, and you could charge your batteries and then use them anywhere you want to.

And we could expand the idea even more. It would take a lot of engineering and careful planning, but eventualy, there has to be a way, to design a wh*** fitness studio, so it would power itself. Of course harnessing the power generated through weight-lifting would be a bit complicated, but. There is also a lot of biking (and simmilar stuff), lever-pressing and pulley-pulling going on. These could generate the power for at least the sound systems, or refrigerator. Furthermore I think, that you dont need to add weights to increase resistance in your training. You can also shift gears, which will not only provide increased resistance (you know it from mountain bikes) but also greater momentum. That way, the more "weight" you are working with, the more energy you produce.

Central computer system could then monitor the energy output and adjust accordingly using standard connection to the electric grid as a backup.

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.
