A crash course in changing the world.

ACT 3 Using alternative forms of energy.

Hello my fellow Evokians

I had a dream around twenty years ago and when i woke up i knew that it was something that I want to make. If I could make this I will add jobs where there are none and help our ailing economy.
I want to make a car that is very lightweight and the shape is semi-spherical. The method of running the car is such that there is a ball in the place of the eccelerator . You would use your foot to spin the ball which causes an electromagnetic induction. "Electromagnetic induction is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field. Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831 (1) I imagine that I would have to build an electric motor that would have enough torque to supply the amount of energy needed to move the vehicle.
1. The circuit must be closed, otherwise electric charges carried by the current acc**ulate at its ends and those acc**ulations create their own electric field, stopping the flow of any additional current.
2. If a current does flow, it contributes its own magnetic field, modifying the one creating it and generally weakening it.
3. If some more complicated relation takes the place of Ohm's Law (as happens, for instance, in plasmas), that relation rules the current flow, often making it more complex.(2)
4. --And... if there is NO electric conductor in the region of changing magnetic field, NO electric current flows. However, there still exists an "induced" electric field E, a modification of the properties of space, though without any material on which it acts, it would be hard to detect it. (2)

So ive found a concept for Description of motion in one dimension from Hyperphysics
Description of Motion in One Dimension
Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). Velocity is the rate of change of displacement and the acceleration is the rate of change of velocity. The average velocity and average acceleration are defined by the relationships:(3)
So this makes me wonder if you can make the acceleration rate climb by using this (ball to connect to induction motor) if my idea will work.
In any case I know that in the US we need jobs to replace outsourced jobs that are never coming back. I would love to design a car that based on the induction method or other electrical sources that are small enough to drive to do errands and at the same time cut down on energy used to do so. I will add my drawing of the car soon. I do not understand the laws of physics to properly show the scale of the motor needed nor the size of the vehicle but I believe it can be done.
I hope that all those who know physics will bear with me!

very interesting how art overlaps the realms of physics and energy

Cool huh?!?!?!?!!?

yes, very

So you're saying that you have to spin a ball constantly to make your car move forwards? Sounds intriguing, but probably very hard to calibrate ahah.

I would imagine so! I was hoping that maybe there would be a series of generators that started from the small force of action of rolling the ball with the foot and that mechanism would set off a series of accelerated amping up of power and you would have to use the same momentum of foot that you do when you ride a skateboard or used a kickwheel to throw a clay pot. I know that the idea is way outer limits stuff but it stuck with me for so long i had to share!

Guys look at this plastic car it is a work of beauty!

Oh one note I am not a shill for shell! hee hee

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. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…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.
