Here we present the first full cell battery device that is developed entirely from scrap metals of brass and steel—two of the most commonly used and discarded metals. A room-temperature chemical process is developed to convert brass and steel into functional electrodes for rechargeable energy storage that transforms these multicomponent alloys into redox-active iron oxide and copper oxide materials.
What about energy?
In physics, energy is a property of objects, transferable among them via fundamental interactions, which can be converted in form but not created or destroyed.
Physics it is the general analysis of nature, conducted in order to understand how the universe behaves.
After all the healthy humanity living in a peaceful, secure and awesome living planet achieve the knowledge of how Nature could synergie objects and energy… then there will be other great problems to solve but at this point humanity has yet accomplished the main steps and procedures to extend a more “universal” and natural way of live.

Solar panel that produces water
Water is collected from thin air, evaporated to remove pollutants using the energy produced from the solar panel.The water collected will then flow out of the faucet placed on the side of the panel.

Clean water with clean energy
New research provides 'stamp' sized nanostructured devices that clean water usign energy from solar spectrum...
Now researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have created a nanostructured device, about half the size of a postage stamp, that disinfects water much faster than the UV method by also making use of the visible part of the solar spectrum, which contains 50 percent of the sun's energy.

More efficient batteries for consumer electronics
“With two-times the energy density, we can make a battery half the size, but that still lasts the same amount of time, as a lithium ion battery. Or we can make a battery the same size as a lithium ion battery, but now it will last twice as long,”

Piezoelectric Generator based on cellulose microfiber
This could be the energy source for implantable electronics...
Cellulose nanogenerators could one day power implanted biomedical devices
Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body—its heartbeats, blood flow and other almost imperceptible but constant movements.
It delivers a high electrical throughput that is an open circuit voltage of ∼30 V and power density ∼9.0 μW/cm3 under repeated hand punching. We demonstrate to power up various portable electronic units by HPG. Because cellulose is a biocompatible material, suggesting that HPG may have greater potential in biomedical applications such as implantable power source in human body.
