About this project

Your electricity price can be 10 times profit mark-up by energy business

For people living in Australia, when you pay your electricity bill, the profit mark-up is about 10 times when coal energy is converted into electrical energy. Steam turbines in the power station will lose nearly 70% of energy produced from coal. 10% of lost energy will occur during transmission. Even at such high energy loss, electricity companies still have a profit mark-up of approx 1000%.

One kilogram of coal costs 7.4 cents. To convert 2 kg coal into electricity at 100% efficiency (which is impossible), we would pay the electricity supply business AU$4.60. That is a potential price mark-up of 3000%. Any efficiency improvement, by the electricity companies, will flow into their business profit. Do not expect that they will pass that saving onto you. It is not that hard to live "off grid" and save money if you have the same technologies as the energy companies. Unless you take your energy generation into your hands, you will not have a say on how much you are going to pay for your electricity.

Below is a table showing the profit mark-up data, when coal is converted into electrical energy. There are many costs involved, for example, power transmission, whole sale electricity and retail electricity are part of the energy business cost. The cost, of these middle men, whould not be needed when you manage your electricity generation at home or in your business, i.e., to live off grid.

What you can see is that at 10% heat engine efficiency, the profit mark-up is still quite good. At the moment, line 7 (30% engine efficiency) is what most electricity grid supply companies can achieve. The higher the engine efficiency, the bigger the profit margin the electricity business can make.  

To live off grid electricity, you need heat engine and generator.

There are many back up power generators in the market. Quite likely it will be a petrol or diesel engine generator. The engine will be less than 20% energy efficient. It is noisy and no one would willing choose to use such a product to generator electricity for home of business.   

Our engine is much more efficient and quiet because it has an extraordinary innovation that will improve energy efficiency as well as reduce noise and emissions.

The challenges in heat engine design. 

  • GAS EXPANSION FORCE IS NOT A CONSTANT FORCE: When a gaseous body has higher pressure than the ambient environment, it will expand until both the expansion body and the environment come to pressure equilibrium. Gas expansion has many types, for example, when the body expands at a constant temperature (isothermal expansion), it will cover more area, as indicated by the curved P_V diagram, than the so-called adiabatic expansion. This means that there will be no transfer of heat or matter between the gas body and the environment. With isothermal expansion, the rule of thumb of rule is that for every 100% expansion in volume the work done will be the same. As seen in the chart below, for the energy that becomes work under the curved P_V diagram, every colored area will be the same in terms of work being done. But when pressure is high, the displacement of the expansion boundary is much shorter than the low pressure region. When you use this gas expansion to a loading that is constant, you will waste a lot of energy, which means the energy efficiency is very low. Why so? Well, in the chart below, the gray color will cover nearly 50% of displacement, while the energy level is 1/8. The brown color occupies 25% of the displacement, with a 1/8 energy ratio. This is one reason that the heat engine is not very efficient when you directly couple the expansion force against a loading that is constant.

  • DO NOT USE TURBINES: This is a hard topic to when using a heat engine. The famous ideal gas law equation PV=nRT is well known. When we apply this equation to a heat engine design, engineers do not seem to understand that when a heat engine is a turbine, the V factor is almost like INFINITE, due to the open gap in between the turbine blades. When the quantity of gas molecules n, and its temperature T are initially constrained by a limited volume V, turbine style heat engine would instantly allow air molecules the opportunity to escape through the turbine blades, which cannot hold them back effectively. It is impossible to make every gas molecules exerting a force turbine blades before before being vented. Have you tried to pump up a balloon using a fan? It is not possible, but you can easily do this with a piston pump, or you can simply blow it up using your mouth.

  • DO NOT USE A CRANKSHAFT: It was James Watts who incorporated crankshaft into heat engine. It is still used in many (or ALL) reciprocating engines. But, there is a problem when the crankshaft is used to convert reciprocation motion into rotary motion. It will cause a massive energy lost.

Crankshaft will make engine very inefficient

Here is the proof using mathematics. As you can see, the torque has no linear relation with the angle of the crankshaft cycle. When the shaft cycle angle is zero, the efficiency is zero.

The heat engine is about THERMAL EXPANSION.  

When water is heated up by fuel, it can become steam. This well-known phenomenon was used by inventors in the 17th century to build steam engines. The steam engine is very inefficient. It is convenient to make steam but LATENT HEAT makes the steam engine very low in energy efficiency.

The power of leverage
The power of leverage

For over 3 centuries, gas expansion has still been the fundamental principle used to power human civilization. From steam engines to Internal Combustion Engines (ICE), from steam turbines to jet engines, engineers work hard in various applications for the benefit of human civilization. The focus in designing heat engines is energy efficiency. One thing that is different with our invention from all of the others, is how to properly modulate the curved expansion. The solution is leverage.  

Smooth the curve with dynamic leverage mechanism

Here is the engine animation. We have a clever mechanical solution to balance the curved gas expansion and compression forces. The engine will have a constant output force, which makes the energy efficiency much higher.

Because of the curved energy distribution in gas expansion and compression, we have invented a heat engine that can dynamically modulate the force, with one simple lever system.  

Replace the crankshaft with a better solution

In order to replace the crankshaft with a better design, this invention has two planetary gears bridged by a lever, which is a metal bar (part 300). This metal bar has a fulcrum moving freely in between two axis of planetary gears. The leverage ratio is in between the INFINITY and 1/INFINITIY. When the force is very high, due to high compression, the engine will gear up the leverage to make the other side run a proportionally longer distance. When the expansion force is low, and the other side compression force is very high, the inversely gear ratio will increase the force while making the piston run a proportionally less distance. That is how leverage works. In this heat engine, the leverage ratio is DYNAMIC.

 

Free fuel is everywhere!  

Here is another interesting fact to help you understand why the heat engine is important. You are given 15 tons of water, 1 cubic meter of normal pressure air, a kilogram of standard coal (dry), two kilograms of dry tree twigs, leaves and branches (Bio-fuel). How are you going to access energy out of this material? 1 kg of coal it has nearly the same amount of chemical energy in 2 kg of dry Bio-fuel. If you raise 15 tons of water by 200 meters in altitude, you can release the same amount of gravitational energy that would be equal to the chemical energy inside 1 kg of coal. For 1m3 of normal air, if you compress it to 200 bars of high-pressure air at the same temperature, you will store 20% of energy potential similar to 1 kg of coal. If you want to store 1 kg of equivalent coal energy into the battery of a typical Tesla electrical car, you will need a li-ion battery weighing 56 kg. 1 kg of coal has 50% of fuel energy of the average home daily electricity energy usage in Australia. It is hard for people to access coal. It is also impossible to build a water tower 200 meters high in your backyard. It is also not practicable to have li-ion battery weighing 56 kg, as a way to supply electricity to your home because you need to consider that when the temperature drops to freezing, or above 40 degrees Celsius, you will use far more energy than is available than a 56 kg li-ion battery can store. It makes sense that, when you have a heat engine in your home and you have the FREE fuel you can collect from the bush or forest when you drive past these places, you can collect fuel for free.

Below is a picture showing people from the "lock the gate alliance" standing in grassland. What is grass? It is THE renewable fuel that is FREE for everyone. If you want to stop our environment from being overly exploited by CSG or fossil energy mining, consider our heat engine as one of your weapons to fight back.

Versatile heat engine:  

This off-grid electricity product is an energy platform for many types of heat source. One of the most important features of this invention is energy storage. The more energy from clean and renewable sources is used, the less greenhouse gas will be released into the atmosphere.

Pure oxygen combustion is another feature that can reduce pollution and help CO2 sequestration. Oxygen reacting with nitrogen at high temperature will create Nitrogen oxide (NxO), which is a pollutant. In our heat engine, an expansion unit called cryogenic expander will help the process of oxygen separation from the air, and CO2 sequestration after combustion.  

With an efficient engine design, all these functions are now possible.

Take action and make a change:

This project is to give people the opportunity to make a change. Everything we are asking for is well within our manufacturing capability. From the cylinder to the piston, from planetary gear to differential gear, we have designed this heat engine with mechanical components that are all easy to build. If we can double heat engine efficiency, our world can cut emissions by 2020, significantly more than the target set by UN Paris COP21.

This is why we decide to set up this project and MAKE IT HAPPEN.

Risks and challenges

This is not a small project. As a matter of fact, the heat engine has nearly 300 years of history since the steam engine was invented. Each year big companies, for example,= car manufacturers, are spending hundreds of millions of dollars on car engine design, with very small improvements in energy efficiency. They simply fail to understand what we have discovered. We have contacted many car makers about our invention. Only Volkswagen replied, we were told it was 'too early for them to get involved'. At that time, VW was exposed worldwide for its emission cheating scandal. Recently Japanese car maker Mitsubishi was found to have been manipulating its car fuel economy results for the past 25 years. We have proposed a business partnership with Mitsubishi, but as yet we are still waiting to receive a response, if we will get one at all.

This project is our launch platform in order to disrupt future car business. We are concerned the trend of electrical cars hype. We believe a battery has too low an energy density to provide a realistic alternative replacement to the current heat engines, its resultant waste and manufacture will also be cause for other environmental problems. The plan to use a battery to store energy for electricity supply must be decisively terminated, by the use of efficient technological alternatives. With a successful off-grid electricity project, we will soon have sufficient data and experience to apply this project as an alternative car engine very soon.
