GLASS BOTTLES

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.

Reuse is better than recycle.

Electric Fan, Exhaust Fan with Remote

I am currently studying electronics and had an idea that you can reverse the rotation of an electric motor that can be used for a wide variety of 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’s 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:

Electric Fan with Remote and Reverse Feature (2)

 

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.

Thank you!

 

 

 

 

 

 

 

Replaceable 9-Volt Battery LED Light Science Project

LED lights and lamps you buy have rechargeable batteries inside, and I must say that it’s a pain to replace them. After how many charging cycles and even though it still works, you just throw the whole lamp away and causing so much waste of resources. So, why not use the LED lamp that lasts using a changeable battery you buy almost everywhere?

I bought a cheap LED flashlight that works great and replaced the rechargeable battery with a 9-volt Eveready battery. Simple enough.

I hope this would help manufacturers design a rechargeable battery that can be replaced easily and make even more affordable.

Harnessing Radio Waves For Electricity

Radio waves are also electricity didn’t you notice? Waves that travel on air to your phones or AM/FM radios by capturing it to an antenna. So, by creating a smaller “radio” transmitter for your home, you can also wireless charge your devices.

A UK firm has also discovered this and developed this idea using multi-band antennas to capture different “radio stations,” to increase the electricity harvested, for low-energy IoT (Internet of Things).

This is exciting times since by this you can wonder how this technology could change our lives by using “free” electricity. Just as Nikola Tesla (the inventor) has envisioned. It’s like that movie where Doctor Octavius wants to harness the energy of the man-made sun to provide cheap electricity for the whole world. Not a lofty goal but perhaps a crazy one (haha).
