Animation production

In this blog, our design team engineer Jorge will give our visitors some introduction of animation rendering by AutoCAD Inventor. The featured video you see in our crowdfunding requires extensive design of individual parts, assembled into a virtual mechanical product. The animation will be produced based the assembly file.

1. 3D model drawing and assembly constraints

Before creating an animation using inventor, the first step is to finish the 3D model which will be animated. All the pieces or assemblies need to be constrained. In most cases, at least one piece should be grounded (this will not be the case when the object you are creating needs to be displaced). In this particular case, the BETE engine should have at least one piece grounded because it won't move from its starting position (Only internal pieces will move or rotate here).

2. Creating motion constraints

After the model is completed, the next step is to constraint the pieces which will move using the "Motion constraints" feature.
There are 2 main kinds of constraints here:
- Rotation: this is used when a piece rotates thanks to the action of another rotating piece. For example a pair of spur gears.
You only need to define the ratio of rotation and the direction.

motion constrain in Autocad

- Rotation-Translation: this one is used when the rotational movement of a piece, creates a linear movement in other, or vice versa. A common use of this is a Rack gear with a pinion spur gear.
The things that need to be defined are the direction, and how much the linear piece will advance every time the rotational piece completes one turn.

autocad constrain

For this specific animation, the motion constraints that will be used are:

- Rotation-Translation constraints, so that when the pistons move back and forth in a linear way, the rack gears will make the pinions rotate.

This also applies to the SM Carriage where the rotation of the output spur gear, will make the carriage move.

- Rotation constraints, so that all the rotational movement from the gears, can be transferred to their respective pairs of gears. Eventually this rotational movement goes to the output shaft, and will move the Synchronous belt to create the output electrical energy.

Now that the motion and assembly constraints are created, you can move on to the animation.

3. Inventor studio

To start the animation, go to the "Environments" tab, and then "Inventor Studio".

Inventor studio menu

  1. Create animation
  2. First create an animation. Procedure: In the left panel of inventor, right click in "Animations", and select "New animation".

    new animation

    Name the animation after it is created. Right click in the animation you just created and select "Activate". Make sure it is active by having a blue check.

    name the animation

    This will be the file in which our animation will be created. Nevertheless, you can create multiple animations if you want to.

     

  3. Creating a scene style
  4. Next step is to create a scene style. Click in the "Scene Styles" button.

    creating a scene style

    Select "New Style" in the upper left button of the window that appeared.

    After it is created, right click on the new style and select "Rename Scene Style". Change its name.

    Right click again and "Activate" the scene style, because this is the scene we want to use for the animation.

    In this example, the Scene is called "BETE Motor Scene".

    Scene styles selection

    There are somethings which should be defined for the scene.

    - Background:

    Select the type of background you want and its color. You can use a gradient background with two colors, or import an image to use as background. In this case we'll use a single blue colored background.

    Scene background selection

    - Environment:

    Select the direction of the ground plane, and an offset if necessary. Also, define the shadows and reflections percentage.

    Scene Environment selection

  5. Creating a lighting style
  6. Click in the "lighting styles button"

    Scene lighting style selection

    Right click and "Rename Lighting Style". After that, right click and "Activate".

    In this example, the lighting style is called "BETE Motor Lighting".

    Lighting Styles selection

    Right click in the new lighting style, and select "New Light".

    New light selection

    There are some things which have to be defined here:

    - General Tab:

    The first thing to do is to select a target for the light to point to. After that you may change the position from where the light comes from. Select what kind of light you want. You can even flip the light direction.

    General Tab for lighting

    Select the color of the light you want and its intensity (in percentage).

    illumination of lighting

    - Shadows tab:

    Select the type, quality and density of the shadows.

    Lighting shadow tab selection

    - Directional tab:

    Define the latitude and longitude where the light comes from.

    Lighting Direction Tab selection

    You can click OK now and the light will be finished.

    If you need additional lights you can repeat the process. In the lighting style you created, right click and select "New Light". Define all settings for the new light. You can create several Lights inside a Lighting style.

  7. Creating a camera
  8. Next we have to create a camera so we can "Record" the clip from a specified angle.

    First, set the inventor into a View you would like to use for the camera. Then, go to the tree in the left side of inventor and right click on the Cameras Icon. Select "Create camera from view".

    In this example, I wanted the camera as my home view.

    3 15

    After created, change the name of the camera if you want to. Then right click and select "Edit".

    Change camera name in edit

    • Select the target and position of the camera.
    • Select the type of projection. A perspective projection enhances the realism in the animation.
    • You can change the camera roll angle to create effects.
    • Define a zoom level for the camera. Make sure the whole image fits in the rectangle which represents what the camera will see.
    • The depth of field can create more advanced effects. By enabling this, you can set the camera to focus a specific area of the picture. This area will look detailed, while the objects outside this area will look blurry.

    Camera advanced effects

    In the previous picture, the rectangle shows what is going to be displayed from this camera view.

    You can create additional cameras if you need to.

    These are the basic settings you can set in order to improve the quality of your animations. Now we can start to create the clip timeline.

  9. Editing the animation timeline
  10. Click in the "Animation timeline" button.

    Editing the animation timeline

    A timeline for the current animation will appear.

    Animation timeline

    The first thing will be to define the animation options. Click in the "Animation Options" button located in the upper right side of the animation timeline.

    Animation timeline options

    Here you have to set the total length of your clip. You can also change the "Default Velocity Profile" so that the animation uses a constant speed, or a non-constant speed which you can define. After setting this, click OK.

    Set animation clip length

    The main things we want to animate in the clip are:

    • The views from the camera or cameras.
    • The motion or assembly constraints defined before.
    • Pieces or assemblies can be faded to show internal things of the model.
    1. Camera Views Animation:
    2. First we will define the starting position for the camera. Click in the list box located in the right side of the animation timeline, and select the camera you want to use (In this case, the one we created before. It's called BETE Motor Home View Camera in this example).

      Starting position for camera

      Click on the camera icon called "Add Camera Action" which is in the left side of the list box. Now the clip will start with this camera view at the beginning of the animation.

      Add camera action

      Now we can take a look at the action editor. Click in the "Expand Action Editor" button, located in the right side of the animation timeline window. Here you can see in detail what is going to happen in the animation. So far, we can see that the camera view will be set in the second 0 of the animation.

      Expand Action Editor

      Now let's suppose we want to leave the camera static for 3 seconds. The procedure to do this is: Change the time of the clip to second 3. You will see that the blue timeline will change its position to 3.

      Add camera at static speed to clip

      Click again in the "Add Camera Action" button (the one with a camera picture). Now you will see that the Camera view Timeline will be filled in blue from second 0 to second 3. That tells us that the view will remain static for these 3 seconds.

      Static animation in clip

      Let's animate the camera moving. For example, let's say I'd like to move from the actual view to another corner in 5 seconds. In the clip, this will go from second 3 to second 8.

      Select second 8 of the animation.

      change static action in clip

      Now go to the view of the model and rotate it to where you want to go with the camera.

      Go to the view of model

      Click again in the "Add Camera Action" button. The timeline will be filled in blue from 3 to 8. During these 5 seconds, the animation will go from the starting home view, to the second view we defined before.

       Add Camera Action

    3. Constraints animations
    4. Let's say I want to animate a piece of the assembly moving.

      Click in the "Animate Constraints" button.

      Constraints animations

      Now you have to select the constraint you want to animate from the left tree. These constraints were created before in the 3D CAD model. In the example, I selected "Mate 16" constraint to be animated.

      Here you can select: the start and end of the constraint animation. Also you need to define the start and end time for the animation.

      In the example, I'm animating Mate 16 from 105 mm to 15 mm. This will happen in a 2 seconds lapse, starting in second 8 and ending in second 10 of the clip.

      Animation constrains

      Additionally, you can set the velocity profile for this animation. You can set a constant or specify a custom speed.

      Animation custom speed setting

      After clicking OK, the animation will appear in the timeline.

      Animation timeline after constrains on clip

      This is pretty much what you need to know about this topic. You can always animate several constraints, even at the same time.

    5. Fade animations

    Click in the "Animate Fade" button.

    Animation Fade

    Select the component or components you want to fade. Select the Start and End Percentage of fading. After that, select the Start and End time for the action.

    In the example, I will Fade Piece "01_003" from 100% to 0%. This will make the piece completely invisible. The action will be completed in 2 seconds, from second 10 to second 12 of the clip.

    Animation Fade in configuration

    Again, you can configure the velocity profile.

    Animation Fade velocity profile

    After clicking ok, the animation timeline will show the fade animation.

    Animation timeline with fade animation

  11. Rendering the animation

At this point, with all the settings made so far, and the Animation Constraints created, you can start to render.

- Render Image:

You can render a single image to determine if a view angle is OK. Select the "Render Image" button.

Render Image

Select the desired Width and Height of the image.

The Camera, Lighting and Scene Styles, should be the ones we created earlier. Finally, Choose a Shaded render type to increase realism.

Render image

Go to the output window. Select if you want to save the image or not.

Select the level of anti-aliasing. Increasing this value will result in greater realism but the rendering time will increase drastically.

Render Image options

In the last window, you can select if you want the true reflection feature. Again, this will increase both the quality of the animation and the time to render it.

Render image options

Now click OK to see the result.

Render Image result

- Render Animation:

Click on the "Render Animation" button. Some of the settings here are the same. The "General" and "Style" windows have the same settings than when rendering an image. Those settings should be the same.

The changes are in the "Output" window.

  • Select where will you save the rendered files.
  • In the time range you can manually write what section to animate. In the example we will render from 0 to second 12, to show the constraints we animated before.
  • Select the anti-aliasing level.
  • Format: here you can choose to create a video right away with the "Video Format", or to create a sequence of images that can be edited later, with the "Image Sequence Format". In this case we'll use the second option.
  • Frame rate. Putting a higher frame rate will create a smoother video, but it will take longer to be rendered.

Render Animation output

After all is done, click in "Render".

4. Using the rendered images to create a clip

After the rendering is completed, you will have a lot of images. Now you can use a Video editing software to complete the animation, for example, the Windows Movie Maker.

Import all the rendered images to the Movie Maker and set the time each image will be displayed. This depends on the frame rate you chose before. For example if you chose a frame rate of 20, it means you will show 20 images per second, so every image should be displayed for 0.05 seconds.

Composing Animation with Images

Export this file to a video format and the animation will be completed.

Living off grid

Your electricity price can be 10 times profit markup by energy business

For people living in Australia, when you pay your electricity bill, the profit markup is about 10 times when coal energy is converted into electricity energy. Steam turbines in the power station will lost nearly 70% of energy. 10% energy lost incurs during transmission. Even at such high energy lost, electricity companies has profit markup at 1000%.

One kilogram of coal costs 7.4 cents. To convert this 1 kg of coal into electricity at 100% energy conversion rate (which is impossible), we will pay the electricity for AU$4.60. That is potential price markup of 3000%. Any efficiency improvement by the electricity companies will flow into their business profit. Don't expect energy companies to pass that saving to you. It is not that hard to live off grid and save money, if you have the same technologies energy companies have. Unless you take your energy in your hand, you will not have a say on how much you are going to pay for your electricity.

Below is the profit markup data when coal is converted into electricity energy. There are many cost factors involved. For example, power transmission network set up and maintenance, labor cost, whole sale electricity and retail electricity price, supply and demand mismatch etc., are just part of cost to be in business. These middle men might not be needed when you manage your electricity generation at home or in your business, i.e., to live off grid.

Electricity-business-profit

What you can see is that at 10% heat engine efficiency, the profit markup is still quite good. At the moment, line 7 is what electricity grid can likely achieve. The higher engine efficiency, the bigger profit margin electricity grid can make.

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

project-title-2

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% of energy efficiency. It is noisy. No one will choose such electricity supply for normal condition.

Our engine is much more efficient and quite because it has extraordinary innovation to improve energy efficiency.

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 expand at constant temperature (isothermal expansion), it will cover more area by the curved P_V diagram than the so called adiabatic expansion, which means there is no transfer of heat or matter between the gas body and the environment. With isothermal expansion, the thumb of rule is: every 100% expansion in volume, the work done is the same. As seen in the chart below, 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 expansion boundary is much shorter than 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 grey color will cover nearly 50% of displacement, while the energy level is 7:1. The brown color occupies 25% of the displacement, with 5:1 energy ratio. This is one reason that heat engine is not very efficient when you directly couple expansion force against a loading that is constant.

displacement and energy distribution chart

DO NOT USE TURBINES: This is a hard to explain topic in heat engine. We know the famous ideal gas law equation PV=nRT. When we apply this equation in heat engine design, engineers don't seems to understand that when a heat engine is a turbine, the V factor is almost like INFINITIVE due to the open gap in between the turbine blades. When quantity of gas molecules n and its temperature T is initially constrain by a limited space V, turbine style heat engine would instantly opens so much escape opportunity for air molecules beyond turbine blades, which can't hold them back effectively. It is impossible to make every gas molecules hitting turbine blades before exiting. Can you try to pump a balloon with a fan? I would say no way. You can do this easily with a piston pump. Or you can simply blow it up with your mouth.

blow-balloons

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

engine-efficiency

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

crankshaft-efficiency-proof

The heat engine is about THERMAL EXPANSION.

the-power-of-leverage

For over 3 centuries, gas expansion is still the fundamental principle to power human civilization. From steam engines to Internal Combustion Engine (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 our invention is different from the others is to make the curved expansion and compression force properly modulated. This 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 force. The engine will have a constant output force, which makes the energy efficiency much higher.

Because 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 crankshaft with a better solution

In order to replace 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 will have a fulcrum moving freely in between two axis of planetary gears. The leverage ratio is in between the INFINITIVE AND the 1/INFINITIVE. When the force is very high due to high compression, the engine will gear up the leverage to make the other side run a long way. 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 less distance. That is how a leverage works. In this heat engine, the leverage ratio is DYNAMIC.

Free fuel is everywhere!

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

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

Versatile heat engine:

energy-and-medium-flow-char

Pure oxygen combustion is another feature that can reduce pollution and help CO2 sequestration. Oxygen reaction with nitrogen in high temperature will create Nitrogen oxide, 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 change:

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

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

Energy Trade

Why Blue Energy needs trading

When the fossil fuel traded as commodity in global market, do you think you can do something about the energy you consume everyday?

While writing this webpage, ABC television aired Dick Smith's own documentary production - Ten Bucks a Liter. In this show, Dick had no discussion on engine efficiency. Neither he pointed out many important "attributes" that differentiate fossil energy and renewable energy. Both factors are important to understand why the world could eventually have petrol price at (or more than) $10/L, if we don't address many important issues, such as, heat engine efficiency.

Blue Energy Buoyancy Engine

Buoyancy definition

Archimedes' principle states that: "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." This discovery, only to be true if the object is within a gravity field, because only when such object is within a gravity field then "weight" exists.

Blue Energy Thermal Engine

Blue Energy Thermal Engine (BETE) is a heat engine similar to a reciprocation engine, for example, Internal Combustion Engine (ICE).

Because crankshaft is a component contributing to very high level of energy waste in a reciprocation engine, we have invented a mechanical system to replace crankshaft. This system provides alternating action caused by gas expansion through a dual_cylinders arrangement, and a creative gear transmission system to tangentially transfer reciprocating force into torque force, which minimizes energy lost seen in a crankshaft solution.

About Blue Energy

"Pray if Armageddon is about to happen".

Yes, Pray, this was the advise from Charles Bolden, the NASA chief, who told lawmakers at an US House of Representatives Science Committee hearing on March, 19th, 2013 on the issue if a potential killer asteroid is about to impact our planet. Basically, in Mr. Bolden's view, so far human beings have no technology yet can stop such events from happening.
