The creation of a fully artificial living cell would signify progress in both understanding current life and the development of synthetic organisms. A crucial component of any living organism is energy generation: the means to power its internal machinery. Because of their relative simplicity, catabolic reactions are the classical means for providing carbon and energy to synthetic cells, and much work has been done in optimizing which energy substrates work best for particular reactions ([ 1 ][1]). Despite robust success using small-molecule energy sources, the possibility of designing anabolic mechanisms that can harvest virtually limitless energy from light is very alluring yet remains unrealized.

Hungarian tech company Platio is expanding the way people can harness solar energy. Its new solar pavers work on home driveways, patios and terraces. Learn more.

But a new invention could allow us to continue generating renewable energy even in the dark, the New York Times reports. Electrical engineer Aaswath Raman, at the University of California in LA, has come up with a device that can harness energy from a dark night sky to power an LED — hinting at a new frontier in renewable energy.

Power of the Dark Side

Raman’s findings were published in the journal Joule today. His device — made from easy-to-find materials including Styrofoam and off-the-shelf aluminum parts — takes advantage of radiative cooling, the process that allows objects to release heat after the Sun sets.

Semi-transparent solar cells that can be incorporated into window glass are a “game-changer” that could transform architecture, urban planning and electricity generation, Australian scientists say in a paper in Nano Energy.

The researchers—led by Professor Jacek Jasieniak from the ARC Centre of Excellence in Exciton Science (Exciton Science) and Monash University—have succeeded in producing next-gen perovskite solar cells that generate electricity while allowing light to pass through. They are now investigating how the new technology could be built into commercial products with Viridian Glass, Australia’s largest glass manufacturer.

This technology will transform windows into active power generators, potentially revolutionizing building design. Two square meters of solar window, the researchers say, will generate about as much electricity as a standard rooftop solar panel.

Circa 2012 Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Innovative 3D designs from an MIT team can more than double the solar power generated from a given area.

Sunflower Electric Power Corp.

JOHNSON CITY – Sunflower Electric Power Corp. and Lightsource BP have announced that the Johnson Corner Solar Project entered commercial operation on April 7. The $37 million project, which was financed and constructed by Lightsource BP, is located approximately 2 miles southwest of Johnson City in Stanton County.

Lightsource BP, a global leader in the development, financing and management of utility-scale solar energy projects, is the project owner and operator. All the energy from the project is being sold under a 25-year power purchase agreement (PPA) to Sunflower, a nonprofit electric utility providing wholesale generation and transmission services to six member-owners serving in central and western Kansas. The National Renewables Cooperative Organization (NRCO) played a key role in helping Sunflower develop this important project for the public power community.

Scientists at the National Renewable Energy Laboratory (NREL) have fabricated a solar cell with an efficiency of nearly 50%.

The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.

“This device really demonstrates the extraordinary potential of multijunction solar cells,” said John Geisz, a principal scientist in the High-Efficiency Crystalline Photovoltaics Group at NREL and lead author of a new paper on the record-setting cell.

A team of organizations has completed construction of a ground-breaking eco-building in Morocco that combines hemp construction with a high-tech solar energy system for total independence from the electrical grid.

The SUNIMPLANT project, designed as a single-family dwelling, was created as an entrant in the recent “Solar Decathlon” organized by the United States Department of Energy and Morocco’s Centre de recherche en Energie solaire et Energies nouvelles. The biannual international competition challenges teams of students to design and construct solar-powered buildings. The most recent edition was hosted in Ben Guerir, Morocco, the first time the competition has been held on the African continent.

“This ‘space-ship’ is advanced in time and reflects a turn not only in North Africa but in hemp construction, which doesn’t have comparable prototypes anywhere in the world,” said Monika Brümmer, a German architect and natural builder who led the project.

Algeria and Germany have initiated project DESERTEC, a huge solar panel project that feeds European/North African countries with green power.

It was intially something they should have done in 2011.

Anyhow, good 👍

So much have time.have been wasted, its time to move on. Time is running out.

L’Algérie et l’Allemagne ont signé un accord préliminaire depuis plusieurs jours pour démarrer le gigantesque projet Desertec. Cela a été communiqué.
