Cycle Paths verses Bike Lanes





Cycle lanes are to damn dangerous, the ducth cycle paths need to be copied in the USA but it is going to take many years of work.

A Heavy Duty Trike





This is a trike my neighbour made some years ago. I don't know how much he would need to charge you, but you should ask him to put a proper sized gear reduction on it rather than using one of the over sized hub motors he sells.

You will need to ask for extra strong hydraulic disc brakes also. Some people just do not understand how dangerous 'cable-pull' brakes can be in the rain on a steep hill with 500lbs or more. I wouldn't trust them even in hot dry weather.

I also recommend 16” moped tires (20” O.D.). And mind that he does not use cheap hubs that parts are becoming scarce for, like any with loose ball-bearings. It's about time the bicycle industry joined the rest of the machine world in using sealed cartridges. 

He should to learn to build spoked trike wheels also. And mounting the rim pulley can be found here.

E-Bike frames



This is the best e-bike frame I have ever seen. Most frames are not made to hold all the batterys and electronics. This would be a very good job for a custom frame builder.

This would make a very strong cargo bike, but the motor still needs to be in the center because hub-motors are worthless for hauling hundreds of pounds up steep hills.

Geared hub motors are not available in more than a 5:1 reduction ratio. And direct drive hub-motors are set in such a high gear that you would need much more energy to climb any hill.

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. This is exactly what the social engineering of the plutocrats is trying to do.


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 money oriented 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.



As long as the bottom line is money, profit or affordability, everyone will loose the competition with the larger business. I also believe that quality is easier to achieve by a small group of people.

Marxism is not communism. Marxism has nothing to do with hierarchical government. The only way Marxism can possibly work is if all the people involved have a say in all the decisions. This is what a true democracy is.

We can't even try to confront the realities of what ails us until we can agree on what the realities 'are'.


This is why the overlords own the news media and create distraction by propagating fear of the kind of change that we need, by hate mongering !!!The money mongers must be controlled!

Marxism is an analysis of the systemic sycophantic behavior of capitalism.

Solar Pedal-Electric Hybrids?

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?

Pros
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!

Cons:

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


https://www.youtube.com/watch?v=cdiZUszYLiA



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.

By increasing the number of phases it is also possible to increase the torque per RMS ampere for the same volume machine. It is assumed that iron saturation can be neglected and that only fundamental air gap flux is taken into account.


It has a rugged simple structure, low manufacturing cost, high torque per unit volume, and the absence of rotor windings resulting in simple control schemes and decreased losses. Therefore, this kind of motor is an attractive candidate for numerous e-bike and electric car applications.

Asymmetric Motor Windings

Asymmetric motors require less voltage to achieve the same maximum rpm and should improve efficiency while reducing current requirements.

The idea of the Asymmetric motor is to balance two Inductors so that as they function in parallel so that the “Back” electromotive forces will cancel them self's out.
The other idea is that a magnet as the driving force for magnetic flux,would work better than brute force originated by copper coils.
