Adapting electricity demand to production. Not the other way around
04.09.15 - Instead of aligning energy production with consumption, wouldn't it be possible to make consumption adapt to the intermittency of renewable energies? François Vuille, director of development at the Energy Center, shares his thoughts.

Light That Adapts to Your Needs Through the Eye of a Camera
Light That Adapts to Your Needs Through the Eye of a Camera
Researchers have developed a camera that sees like the human eye, providing clues about the sensation of visual comfort. The instrument could optimize natural and artificial lighting to constantly adapt to the needs of the user. How can we combine visual comfort with electrical energy savings? Light inside the home is a theme that has interested researchers for over a half century.

Paying rent with sugar and fat
Paying rent with sugar and fat
Powering coral reefs: Scientists have revealed how coral-dwelling microalgae harvest nutrients from the surrounding seawater and shuttle them out to their coral hosts, sustaining a fragile ecosystem that is under threat. Coral reefs are the jungles of the oceans, home to some of the planet's most fertile fishing grounds, and hotspots of global tourism.

Experiment sheds new light on cloud formation
Experiment sheds new light on cloud formation
CERN 's CLOUD experiment has shown that biogenic vapours emitted by trees and oxidised in the atmosphere have a significant impact on the formation of clouds, thus helping to cool the planet. These biogenic aerosols are what give forests seen from afar their characteristic blue haze. The CLOUD study shows that the oxidised biogenic vapours bind with sulphuric acid to form embryonic particles which can then grow to become the seeds on which cloud droplets can form.

Sunlight to jet fuel
Sunlight to jet fuel
In the framework of the EU-project Solarjet, scientists demonstrate for the first time the entire production path to liquid hydrocarbon fuels from water, CO2 and solar energy. The key technological component is a solar reactor developed at ETH Zurich. By playing this video, you agree to the use of cookies by YouTube This may include analytics, personalization, and ads.

The entire production path of "solar" kerosene
With the first ever production of synthesized "solar" jet fuel, the EU-funded SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide (CO2), therein potentially revolutionizing the future of aviation.

Analyzing Lake Geneva from the air
Analyzing Lake Geneva from the air
One year after the MIR submersibles dove into the depths of Lake Geneva, the elemo program is delivering its first scientific results. The operation will be extended with a campaign to make observations above the lake surface from a sensor-packed ultralight aircraft. The same experiments are planned above Lake Baikal in Russia.

The historical value of pre-fabricated buildings
The historical value of pre-fabricated buildings
Is post-war industrial and pre-fab architecture worth preserving and renovating? To answer this question, architects conducted a three-year pioneering study into the restoration of modern buildings.

Humans influencing climate since over 2000 years
Humans influencing climate since over 2000 years
New data extracted from Greenland's glaciers show that methane in the atmosphere follows the waxing and waning of civilizations. Humans have been producing substantial amounts of greenhouse gases since long before the industrial revolution 2012. By studying the tiny amounts of gases trapped in air bubbles in Greenland's glaciers, researchers have been able to add details to an emerging picture of historical human induced environmental change that reaches as far back as the Roman Empire and the Han Dynasty.

Nano-velcro clasps heavy metal molecules in its grips
Researchers develop nano-strips for inexpensive testing of mercury levels in our lakes and oceans with unprecedented sensitivity Mercury, when dumped in lakes and rivers, accumulates in fish, and often ends up on our plates. A Swiss-American team of researchers led by Francesco Stellacci at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and Bartosz Grzybowski at Northwestern University has devised a simple, inexpensive system based on nanoparticles, a kind of nano-velcro, to detect and trap this toxic pollutant as well as others.

Under a warm blanket of snow
Researchers are studying the effects of climate change on the degradation of organic matter in the soil. First results underline the importance of the thermal insulation provided by an intact layer of snow on the dynamics of soil microorganisms. You'd think that during the winter, all life trapped beneath a layer of snow would shut down and wait for warmer days.

A guiding light for new directions in energy production
Advances in the field could help solve the energy challenge. The science of light and liquids has been intimately entwined since Léon Foucault discovered the speed of light in 1862, when he observed that light travels more slowly in water than in air.

Unprecedented insight into cloud formation
Unprecedented insight into cloud formation
The CLOUD experiment has been designed to study the effect of cosmic rays on the formation of atmospheric aerosols - tiny liquid or solid particles suspended in the atmosphere - under controlled laboratory conditions. Atmospheric aerosols are thought to be responsible for a large fraction of the seeds that form cloud droplets.
