More back alley science

Hey guys, hows the domes holdin up after that spooky neutrino shit? Oh you weren’t phased by that? Apparently breaking the speed of light is whatevs, well let me lay some real HEAVY shit on you.


So we all know how bitchin LED TV’s are. Well what if I told you, we put them sukkas in some CONTACT LENSES. (ok, well one pixel, but dammit thats good enough for me)

Don’t worry tho they are powered by Radioactive Isotopes, TOTALLY SAFE.

Technically yea, they are safe, but come on, im supposed to put radioactive shit in my eyes?

Good thing we are developing this:

Flexible microchips, powered by the kinetic energy of your HEART. I mean it’s keeping you alive, big deal, it needs to also power our Ipod, and our super awesome eyeball TVs

Dear future, hurry up and make me Robo-Cody


Scientists in India and Germany have unveiled a material that generates tiny amounts of electricity from mechanical stresses like a person’s touch or step. The idea is to create a biodegradable energy source that can pump electricity into a storage supercapacitor to power electronics, replace batteries and safely break down without polluting the environment. 

Their material, described in the journal Applied Materials & Interfaces, is a biodegradable plastic polymer called polyvinylidene difluoride sandwiched between conducting carbon electrodes. Interestingly, they mixed DNA with the plastic because the genetic material is biodegradable while having properties that help harvest electricity. In fact, DNA is known for its ability to accumulate electric charge when mechanical stress is applied to the molecule, a property called piezoelectricity.

In lab tests, a researcher pressing on a small piece of the prototype material generated enough electricity to light 55 blue LEDs. Putting the material on a shoe and then juggling a soccer ball, they recorded small bursts of electricity with every hit.

Electricity generating fabric

Above: Schematic illustration shows the microfiber nanowire hybrid nanogenerator, which is the basis of using fabrics for generating electricity.

The researchers harvested energy from the environment by converting low-frequency vibrations into electricity. Those vibrations came from simple body movements, the beating of the heart or movement of the wind. They did so with zinc oxide nanowires that conduct the electricity. The zinc oxide nanowires are piezoelectric — they generate an electric current when subjected to mechanical stress. The diameter and length of the wire are 1/5,000th and 1/25th the diameter of a human hair.

Flexible nanogenerator sees 40x energy efficiency increase - Infinite power to be commercialized soon

NANOGENERATORS are innovative self-powered energy harvesters that convert kinetic energy created from vibrational and mechanical sources into electrical power, removing the need of external circuits or batteries for electronic devices. This innovation is vital in realizing sustainable energy generation in isolated, inaccessible, or indoor environments and even in the human body.


Self-powered clothes?

Fabrics with the ability to create electrical charge through movement have been an area of interest for a few years. Researchers at Georgia Institute of Technology, USA, have added solar energy to this concept, developing a fabric that can simultaneously gather energy from motion and the sun.

The fabric is made with a commercial textile machine, which weaves together solar cells made of lightweight polymer fibres with fibre-based triboelectric nanogenerators. The nanogenerators use the trobelectric effect and electrostatic induction to generate power from movement.

The material is 320 micrometres thick when woven together with strands of wool. The team envision it being used in tents, curtains and wearable garments.

Being held out of a car window, causing it to blow in the wind, a 4x5cm piece of fabric was tested. The results showed that two volts were obtained in a one-minute period.

The team say the fabric is robust and able to withstand vigorous use. The next steps include further optimisation for industrial use.  

New fabric uses sun and wind to power devices

Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers at Georgia Institute of Technology have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion.

Combining two types of electricity generation into one textile paves the way for developing garments that could provide their own source of energy to power devices such as smart phones or global positioning systems.

“This hybrid power textile presents a novel solution to charging devices in the field from something as simple as the wind blowing on a sunny day,” said Zhong Lin Wang, a Regents professor in the Georgia Tech School of Materials Science and Engineering.

The research was reported September 12 in Nature Energy.

200x power increase in nanogenerators could enable powering of many devices simply from movement

Korea Advanced Institute of Science and Technology (KAIST) researchers have discovered how to radically improve conversion of ambient energy (such as body movement) to electrical energy for powering wearable and portable devices.

As has been noted on KurzweilAI, energy-harvesting devices can convert ambient mechanical energy sources — including body movement, sound, and other forms of vibration — into electricity.
