Happy New Year! Ain’t that awesome? Here we are surviving at least to be MORE awesome in 2019!
I challenge you to invent something that will change the world. A machine, a song or even a poem to make people’s lives different (in a good way). Be Steve Jobs, be Nikola Tesla, be a hero! Saving the world is no easy task, but at least we’ve enjoyed the journey towards progress.
This is not a special water pipe, I’m talking about the ordinary water pipes that is used by a city to distribute tap water. And, this is not the small pipes around the house, I’m talking about the huge pipes that engineers made for water distribution in the city.
Why water pipes? Water is pumped through these pipes so we could use it. It uses pressure to push through water and uses electricity. So, how can it produce electricity?
Just like windmill generators, it uses the same concept on generating electricity by using a motor that generates current when the armature inside the the turbine rotates between two polar field magnets. Now, by using the same turbine, you can put this to apply it on water pipes to generate electricity. And, you are talking about 24-hour, round-the-clock electricity for the whole city.
I’ve been dabbling previously with a Raspberry Pi single-board computer, and amazed on how this tiny computer can do so many things. You can add sensors like temperature sensor to monitor the environment and record this in a file where you can review its data. Or, you can attach a servo so you can turn on the light switch by Tweeting a command online, anywhere!
The only problem is it is a mini desktop and you need to plug it in an electrical outlet. Therefore, portability is a problem.
An idea just switched on me since Raspberry Pi is an Internet Of Things computer, why not create a laptop that has IO board you can attach to a USB port or Thunderbolt ports, and you can now use this laptop just like a Raspberry Pi!
This is super useful for students and teachers alike, and it would be great to do so much more and even save the world!
This is a vertical-axis wind turbine that rotates in different wind direction, thus ensuring electricity generation efficiently. You can stack this into three per pole to provide more energy and saving space. Materials for this is cheaper using plastics, which is lighter for stability and easier deployment.
Here is a render:
Vertical Axis Stacked Wind Turbine
As you can see, the upper half of the sketch is just tilted vertically to view the scale of the turbine. The bottom half of the render shows the side view and the top view.
This is basically the same principle as the weather apparatus used to measure wind speed.
This took me days to figure out what’s wrong. Although I got it from the Internet on how to make this, and there are step-by-step instructions, I just couldn’t figure it out. Luckily, after searching, I found a video that explains for this to work, you need the coil to have only one side exposed in a vertical manner. You just have to sand paper one side of the coil at both ends, touching the electric current from the battery.
How I wish that they use glass bottles again instead of plastic pet bottles. Glass bottles can be reused by dipping them in antiseptic solution and it is clean again, while pet bottles are just thrown and piled up in landfills that cause pollution on seas, riverbeds, poison the soil, kill wildlife and damage the ecosystem. If you’re going to recycle plastic, you’ll need expensive equipment and costs are high. While glass bottles are more cost effective and have longevity.
I am currently studying electronics and had an idea that you can reverse the rotation of an electric motor that can be used in a wide variety purposes. For example, an electric fan’s motor rotation can rotate clockwise AND counter-clockwise without any mechanical but pure electronics. By reversing the polarity of an electric charge, the motor will rotate in a reversed motion. Practically, this can be applied in electric fans and serving also as an exhaust fan.
Another idea is to use a remote control to the fan, for the customer’s convenience sake. Funny, because this is used primarily on children’s toys like remote controlled cars or RCs.
Here is a render of the electric/ exhaust fan with remote control:
Note: I used 3D Rota-aire design as basis.
I have to point out from the render that the rotation of the grills is different from the rotation of the electric motor.
