Sunny Morocco seems like the ideal place to produce solar power.

Just north of Marrakech lies the Green Energy Park, where researchers are working on making green energy technology more affordable, as part of Morocco’s drive to reduce energy dependency.

Euronews’ Denis Loctier visited their concentrated solar power (CSP) plant, where he spoke to the coordinator of the EU-funded project, MinWaterCSP, Falk Mohasseb.

How we can turn the cold of outer space into a renewable resource | Aaswath Raman

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he’s developing to harness “night-sky cooling” — a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it — which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.

STIRLING ENGINE FRESNEL LENS SOLAR POWER GREEN ENERGY SUN Sterling Motor

GREEN POWER SCIENCE STIRLING ENGINE AND A FRESNEL LENS 1800 RPMS. HAD TO STOP AS ENGINE HEAT SHAFT WAS GETTING TOO HOT. This stirling engine converts heat into kinetic free energy from the sun.

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. Or more specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. It is the inclusion of a regenerator that differentiates the Stirling engine from other closed cycle hot air engines.
Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.
The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source. This compatibility with alternative and renewable energy sources has become increasingly significant as the price of conventional fuels rises, and also in light of concerns such as peak oil and climate change. This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.[

Sweden ‘Most Sustainable Country in the World’

“Sweden is the most sustainable country in the world, a ranking it earned for its use of renewable energy sources and low carbon dioxide emissions, as well as social and governance practices such as labor participation, education and institutional framework, according to a report by sustainability investment firm Robecosam.”

The World’s 5 Most Environmentally Friendly Countries
