World’s First Circumnavigation By Solar Powered Ship a Success
Posted by Quinn Sena in categories: solar power, sustainability
Circa 2012
At 2:12 PM local time today, the MS *Tûranor *entered Monaco’s Hercule Harbor, becoming the first ship to travel around the world using only solar power.
It’s the same harbor where the *Tûranor *set out from more than 19 months and 37,286 miles ago. Since then, the ship has made port in six continents, fended off pirates and broke four Guinness world records, including longest journey by solar powered boat and first circumnavigation by solar powered boat.

Goodbye, Oil: US Navy Cracks New Renewable Energy Technology To Turn Seawater Into Fuel, Allowing Ships To Stay At Sea Longer
Posted by Quinn Sena in categories: energy, military, sustainability
Circa 2014
After decades of experiments, U.S. Navy scientists believe they may have solved one of the world’s great challenges: how to turn seawater into fuel.
The development of a liquid hydrocarbon fuel could one day relieve the military’s dependence on oil-based fuels and is being heralded as a “game changer” because it could allow military ships to develop their own fuel and stay operational 100 percent of the time, rather than having to refuel at sea.

Scalable all-perovskite tandem solar cells with a 19.1% efficiency
Posted by Shubham Ghosh Roy in categories: solar power, sustainability
Now, researchers at the Karlsruhe Institute of Technology (KIT) have developed a prototype for fully scalable all–perovskite tandem solar modules. They were able to scale up individual perovskite cells with a power conversion efficiency of up to 23.5% at an aperture area of 0.1 square centimeters to all-perovskite tandem solar modules with an efficiency of up to 19.1% with an aperture area of 12.25 square centimeters.
The aperture area is the usable part of the surface that is not covered by electrodes, frames, or fasteners. At approximately five percent, the loss of efficiency when upscaling is relatively low. “This is the first report of an all-perovskite tandem solar module worldwide,” says Dr. Bahram Abdollahi Nejand, lead author of the publication and team leader for all-perovskite tandem solar modules.
The KIT researchers claimed this remarkable result is the first of its kind reported worldwide. To obtain this, the team increased the efficiency by optimizing the light path and reducing reflections in the solar cell architecture. They implemented an efficient layout for tandem solar modules using high-throughput laser scribing that enables the production of functional tandem solar mini-modules with two-terminal interconnected cell strips. Lastly, they used coating processes (blade coating and vacuum deposition) that are already established in industrial practice.

New ‘future-proof’ method could remove phosphorus from wastewater using bacteria
Posted by Shubham Ghosh Roy in categories: bioengineering, chemistry, climatology, physics, sustainability
A recent study from the Singapore Centre for Environmental Life Sciences Engineering (SCELSE) at Nanyang Technological University (NTU) and published in Wa | Chemistry And Physics.
This study is intriguing since one of the results of climate change is increasing water temperatures, so removing phosphorus from such waters will prove invaluable in the future, with this study appropriately being referred to as a “future-proof” method.

U.S. Eastern Seaboard is Seeing the Beginning of a Freshwater Crisis
Posted by Len Rosen in categories: climatology, sustainability
Below the surface of US coastal cities and towns, the salt line is rising in aquifers used for fresh water. The cause is climate change.
As sea levels rise, saltwater will intrude into groundwater. For more than 600 million who draw on aquifers, it means a freshwater crisis.
