A Cure for Capitalism

A lot of people I know have already given up on the future. I think it is because they don't know what to do and don't want to even think about doing more than what they're already doing to pay the rent, which includes paying for an energy gulping, smog spewing vehicle!

if you think it is impossible to change our lifestyle and It doesn't matter because global environmental entropy is not man made you will never even try to change your excessive lifestyle.

Profit based business creates entropy simply because they have no clue how to design a minimalist vehicle without using the cheapest parts. That's what capitalism is all about; undercutting the small scale high quality business. 

But if we don't start building a social movement to create the ground work, like building worker directed community owned businesses, life will become very hard to survive.

Be warned that “Entrepreneurialism” is another word for “venture-capitalism”

A thriving co-operative economy through entrepreneurialism?

All that is needed is a credit union with a commitment to helping co-ops and employee-owned firms that are committed to sustainable development of communities. Like entrepreneurial organizations ready to help solve such problems as downsizing our life styles. If we wait for the “market forces” to to pay for the downsizing it will be too late to do anything.

Solar Pedal-Electric Hybrids?

3D modeling:

The reason solar cars are not on the road yet is that solar-voltaic cells convert only 30% of the energy received into electricity to move the wheels. So on a dark day, you're not going very far. Solar concentrators can be used over the voltaic cells. Solar panels may be helpful if your vehicle can be parked in the sun for several hours.

But in the real world you will need a fast charger and a pedal powered generator as well.

Direct drive hub-motors were developed for racing, not stop-n'-go city driving. But with this new “magnetic gear motor” things could change if it really works like they say. Or an AC three phase hub-motor that can be vector controlled.

Carbon fiber is not the “strongest” material. It's the epoxy laid into the substrate that makes it strong. News-paper would be a good substitute; it is not much heavier than carbon fiber.

There is no reason that these micro cars would cost too much to build, if you can keep the weight and speed down to bicycle part's abilities. And if you consider how much hidden expense there is in using petroleum power.

But beware of the efficiency paradox:
If you make a machine that is more efficient it will serve to proliferate larger vehicles. Take the efficiency of the catalytic converter for an example: the American car industry created a demand for larger vehicles. So now the amount of fuel used, and subsequent pollution is even more than before. This is the best reason to keep the vehicle small enough to use the human powered pedals, is that pedal powered vehicles are more efficient than electric vehicles could possibly be.

Electric Overdrive

Variable Field Brushless Motor

Variable rotor stator alignment for a solar racing car. It creates more speed per power used when the stator is pulled out of the rotor; like shifting into a higher gear. But probably won't give more torque-thrust per wattage.

Magnetic Gear Motors?

This is a new kind of machine, but not a new idea. It is “the most compact highest torque-thrust electric machine ever made”. It could solve the hill climbing problem of direct drive hub-motors by producing a much wider usable speed range; but no one seems to know if this is going to work like they say it will. Magnetic gearing?

It seems to me that this tech would be really well suited to a crank drive since you can achieve great torque output while still being efficient at low speeds!


The bottom line is that their 1,000 watt PDD's with a 500 rpm output weigh 6 kilo's! (13.22 lbs) a bit much for most “weight weenys”, but not too bad for a large cargo bike!

Conspiracy or Opportunity?

Never Give Up!

I just do not understand how anyone can afford an effing car!
It can take 9 thousand dollars a year just to maintain a new car.

A barrel of oil contains about 11 years of manual labor.
And the average Amerikan uses the equivalent of 60 barrels a year. That is about 660 years of manual labor. Nothing will replace this decadent use of energy.

Extreme conservation might cut the need down to 80% but that is still 528 years of labor that each person needs. So you can forget about electric cars. You will be very luck if you can afford an electric cargo bike, or any bicycle at all.

The more preparation done in advance of the coming crises, the less of a crises it will be! The only reason it is a crises at all, is because not enough people are prepared to change their lifestyles! If you want a conspiracy to think about, look inside yourself!

The great awakening will start a movement like none other in all of mankind's existence before. Building an infrastructure that does not depend on a dirty fuel, that keeps us from taking care of our self's, will change the world's “class” structure also.

Solar energy has the largest potential to disrupt the fossil fuel industry's grip on our lives. But people are going to have to downsize their power usage severely!!

If we cannot learn to develop a sustainable paradigm, life can only get much harder. Deforestation and soil degradation will destroy our so called civilisation; both are caused by our insanely unnatural lifestyle. Humanity will be making some serious changes soon, you may as well make the best of it.

Only a crisis -actual or reprieved- produces real change. When that crisis occurs the actions we take depend on the ideas laying around. That is why we must develop alternatives to existing transportation now.

  Feed your dreams with realistic new solutions, and your fears will starve

Energy returned on Energy invested

The only way to save our biosphere from our consumerist culture is by returning to a tribalistic lifestyle. We have no chance of survival at all if we continue our relationship to each other “purely as consumers”. Our brainwashing is so complete that we can''t even think about sharing. Personally I believe that it will take several massive disasters for most of us to return to a “group-effort” lifestyle.

New electric vehicles will not solve one damn bit of the problem! And not just because 13 tons of hazardous manufacturing waste is produced for every ton of new vehicle! But because capitalism has failed and will continue to fail to give the vast majority of us what we really need; a sense of community.

It takes 10 calories of hydrocarbon energy to produce one calorie of food in the industrialized world.

Energy returned on energy invested (world average) ratios
Oil 10:1 (it started at 100:1)
Coal 3:1
Tar sands 2:1
Nuclear 2:1
Wind Electricity 25:1
PV Solar Electricity 10:1
Ethanol 1:1
Hydrogen 0.5:1 (hydrogen fuels are a scam)
Biodiesel 2:1

Vector Control or Voltage Multiplier

Field oriented control is a better way to make motors produce more thrust at lower and higher speeds than using gears. With controllers having more computing power now, they can control a motor much better than ever before. It requires a three-phase AC motor and a more expensive controller. These would be very good for a motorcycle that needs a wider range of torque-thrust than a simple electric bicycle.

Voltage Multiplier

If the fixed gear is set at a speed to cruise at 20mph on flat land and you need more power to climb a steep hill, using more amperage could overheat the motor unless it has very thick heavy winding wires. (Electrons cause friction). But you can double the voltage with out increasing the amperage to have enough power, keeping the motor cooler.

But it would be cheaper and more efficient to just have a controller with the phase current you need to power a high enough Kv motor to achieve the torque requirements and speed required.

But you can't expect more than a 10% improvement.

More Motors for more Hill Climbing Power

Multiple motors can pump-up the output thrust without increasing the top speed that is set by the fixed gear ratio. A controller for each motor is needed but then you can program them to power-up the extra motors when needed.

What are the advantages? Electric motors loose thrust ability when climbing hills at a slow speed; if you want your high speed gear-ratio to be set at about 20mph and you need a 10mph gear ratio to get enough thrust to climb your hill with only one motor, a second or third should provide enough thrust at 20mph without having to use a larger motor. The bigger motor would take more amperage to keep running at a high speed when cruising on flatter land, where the extra power is not needed. Also motors made for high speed are more efficient than slow speed motors; less energy is turned into heat. These are 3210 Astro Brushless Motors, they are very expensive and powerful. You can use cheaper motors.

Two speed reduction ratios?

I like the idea of using two motors separately the most. One with a large gear ratio reduction and the other with a higher speed reduction. Then the controllers set to turn on the slower gear reduction when needed and the other to turn off. Making it a two speed machine with the same legal wattage.


Dual motor

You can do this with One battery pack, One throttle, One 3-Way & Cruise & EBrake using Two controllers paralleled, Two motors individually tied to each controller, and Two CAs - one for each.

The overall power is divided somewhat arbitrarily between the two controllers depending on load.
  • Going uphill, both will pull evenly.
  • On somewhat of a flat whilst in Cruise Control, one will take the lead and the other will go into "slip mode"; pull enough current so that it essentially freewheels... however on the slightest increase in load - it will pick up the slack until Cruise cannot be held.

I don't measure Amps; I measure pack Voltage because the shunts have been modified by trace-beefing and I do not have equipment capable of measuring scant ohms accurately, so I just measure voltage. I know the battery capacity, I know from experience how to set the amount of theoretical current to the wheels, and thus am able to calculate roughly the overall power consumption. The CAs validate this by using Miles per charge; I know how many miles I should have covered by x-amount of voltage drop - which is not exactly linear, but then I understand that too.”

Our problem is NOT the lack of appropriate technology.

The problem goes way beyond technical solutions. It is a social problem.

Green solutions are too little too late” says Lovelock. But others say “All we need to do is completely reinvent energy and how we use it”. Think Biological Architecture, light from Algae, and downsized 'velomobile' cars; powered in part with very thin solar voltaic panels.


Earth Day

Most people have no idea what the world is coming to, and would rather not know! Sustainable food supply systems are far from being adequate. Electric and even Nuclear powered vehicles will not keep America moving adequately. This will affect the food supply system more than you can imagine.

There are a lot of people that claim to be getting people ready to live without petroleum. But they seem to be waiting for entrepreneurial companies to do the work, and you know that requires a pre-established market demand.

We should be doing these things for our self's. Every community needs to organize a way to be putting solar electric panels on people's houses and building small electric vehicles, as well as growing food locally. Are people going to wait until they are desperate before they downsize their lifestyles?

New electric cars will NOT save the world! A second generation mainstream electric car is expected to use upwards of 5000 kWh of electricity to drive about 20,000 miles a year. It is now possible to reduce your carbon footprint to very close to zero by using a minimalist vehicle like a velomobile; pedal assisted electric cars. But they should be designed for your local terrain.

I built a small cycle-truck four years ago, designed to sit up straight to keep my back pain from killing me. I could not find a bicycle with all the features that I needed, at any price. And if light weight batteries did not cost so much I would have already put a motor on it.

Now I save at least a thousand dollars a month by not owning a car; And still haul all the cargo I need, but my Bionic legs hurt! I really need an organization to get a grant to start building small heavy duty electric vehicles.

A long European style electric cargo bike can haul enough tools and building materials to pay for for the initial investment in only a few months. And if you motorize it correctly there would be no problem climbing our steep hills. If you want to replace a car with a cargo bike or trike, you really need one that will drive at least 600lbs (total combined weight) up at least a an 8% grade at a legal speed of less than 20mph. That means high torque at slow speeds, not many people know how to build such a machine.

So most people put their trust in the builders, that are built for mostly flat land to get a longer roving range; not the best thing for steep hills.

Velomobiles have an efficiency of 40 miles to 85 miles per kilowatt hour of electricity, depending on the weight, speed, gears used, and hills you climb. As opposed to 3.7 miles per kWh for a full sized electric car. How can anyone not afford to own one of these minimalist vehicles?

33.4 kiloWatt-hour is equivalent to one gallon of gasoline. That's about 125mpg for the full sized car, and over 1347 mpg for the heavy velomobile!

The great awakening!

Soon there will be a mass awakening to the absolute necessity to deal with the global life-support-system collapse. Yes the human race will survive, but it will take a wartime effort. But “climate denialists” will be motivated by money. When the environment crashes, so will the economy. Life will change, the world will be a much better place to live. 

It totally amazes me how people obsess on conspiracies of all kind just to keep from taking responsibility for their part in the global heat problem.
