Holograms could hold the secret to solving a common problem with solar cell designs, allowing solar cells to capture sunlight that would normally be wasted and boosting electricity yields by as much as five per cent.
The research, recently published in the Journal of Photonics for Energy, was led by scientists from the University of Arizona who have proposed the use of ‘holographic light collectors’ to steer light that would normally be wasted towards parts of a solar cell that can convert the sunlight into useful electricity.
The problem the researchers were trying to solve is how to utilise parts of solar cells that are usually blocked from receiving sunlight due to the way solar cells are designed.
And here’s another snippet:
In February, more than 500 scientists and economists wrote to President Joe Biden and other leaders to warn that converting wood into power is a carbon disaster, a forest destroyer and an absurdly inefficient way to generate energy… Trees are more valuable alive than dead.
According to Earth Institute, woody biomass power plants actually produce more “global warming CO2” than fossil fuel plants; i.e., 65% more CO2 per megawatt hour than modern coal plants and 285% more CO2 than natural gas. Meanwhile Canada and the U.S. deliver wood to Europe like there’s no tomorrow.
According to LSA – University of Colorado/Boulder: Wood accounts for 79% of biomass production and accounts for 3.2% of energy production. Wood dominates the worldwide biomass industry. Today 50% of EU renewable energy is based upon biomass, and it is on the rise.
The Organization for Ethical Source Takes on Stewardship of Contributor Covenant
GENEVA, May 27, 2021, the preeminent code of conduct for open source communities. Today, this historic document enters the next phase of its evolution, said Nathan Schnieder, professor of media studies at the University of Colorado Boulder and OES member. This milestone marks its exit to community, as Contributor Covenant graduates from a passion project into a community-owned asset.
Contributor Covenant was created in 2014 by Coraline Ada Ehmke, an internationally recognized engineer and activist. In 2019 she created the Hippocratic License, which prohibits the use of software in the violation of internationally recognized human rights, and launched the Ethical Source Movement. Ehmke co-founded the OES earlier this year, and is announcing her new full-time role as the organization s first executive director.
