Graphene amplifier unlocks hidden frequencies in the electromagnetic spectrum

February 18th, 2020 at 12:26 pm » Comments Off

Light in the THz frequencies hits the ‘sandwich’ and is reflected with additional energy. Credit: Loughborough University Researchers have created a unique device which will unlock the elusive terahertz wavelengths and make revolutionary new technologies possible. Terahertz waves (THz) sit between microwaves and infrared in the light frequency spectrum, but due to their low energy, […]



Lasers etch a ‘perfect’ solar energy absorber

February 18th, 2020 at 12:23 pm » Comments Off

Using femto-second lasers to etch metallic structures, University of Rochester Institute of Optics professor Chunlei Guo and his team have developed a technique that can be used to collect sunlight to heat etched metal surfaces, which can then power an electrical generator for solar power.

New research explains how solar panels could soon be generating power at night

February 16th, 2020 at 12:44 pm » Comments Off

As beneficial as current solar panel technology has been in our quest to switch to renewable energy, such panels can’t generate electricity at night. Now, new research suggests it could be possible to design panels that can operate around the clock. Under optimum conditions, at night these specially designed photovoltaic cells could generate a quarter […]



Company to harvest green hydrogen by igniting oil fires underground

February 14th, 2020 at 11:55 am » Comments Off

Injection wells at the Superb oil field in Canada. To make hydrogen, workers heat the reservoir with steam and feed it air, setting off underground oil fires. This month, on the frozen plains of Saskatchewan in Canada, workers began to inject steam and air into the Superb field, a layer of sand 700 meters down […]



New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

February 13th, 2020 at 12:51 pm » Comments Off

New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based electricity generator (DEG) with a field-effect transistor (FET)-like structure that allows for high energy conversion efficiency and instantaneous power density […]



10 disruptive trends for 2020

February 12th, 2020 at 12:07 pm » Comments Off

Disruption is everywhere. Here are 10 trends that will create opportunities – and threats – in 2020. Twenty years ago, when I started advising startups and Fortune 500 companies on their innovation strategies, a “2020 vision” served as a key staple in most business planning efforts. The future is finally here. Emerging technologies catalyze disruption. […]



MIT’s solid-state battery breakthrough may see phones last for days

February 11th, 2020 at 12:51 pm » Comments Off

A breakthrough in battery architecture could lead to lithium batteries with far greater energy densities than those used today One of the many ways scientists hope to improve the performance of today’s lithium batteries is by swapping out some of the liquid components for solid ones. Known as solid-state batteries, these experimental devices could greatly […]



New quantum switch turns metals into insulators

February 10th, 2020 at 12:04 pm » Comments Off

Artist’s impression of the dissolving of the electronic ‘traffic jam.’ The red atoms are different in their quantum nature and allow transport of electrons in their surroundings. Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick […]



Hydrogen is a bad car fuel, but it’s the perfect boat fuel

February 9th, 2020 at 3:13 pm » Comments Off

Because boats are cars too There are issues inherent with hydrogen as a fuel for cars. It is incredibly expensive and energy intensive to create, it is difficult to pressurize and transport, and the infrastructure for hydrogen as fuel is far less developed than battery electric charging. A few automotive manufacturers, chiefly Honda and Toyota, […]



Hydrogen-fueled Drones Will Inspect U.S. Gas Pipeline

February 6th, 2020 at 2:57 pm » Comments Off

Public-safety drone consultancy Skyfire Consulting has announced a partnership with UAV company Doosan Mobility Innovation and hydrogen-fuel service provider ReadyH2 to tackle a pipeline-inspection project for an unnamed American company. Doosan will deploy a hydrogen-powered octocopter. The drone sports a hydrogen-powered generator fueling two hours of flight time per mission over nearly 50 miles. ReadyH2, […]



The smart cell turning solar energy into hydrogen

February 6th, 2020 at 2:54 pm » Comments Off

What could be better than a solar cell that captures most of the visible light spectrum to generate energy? A cell that can capture the whole visible light spectrum and turn the energy into hydrogen. The cell is actually a molecule, and it is a busy molecule: it not only harnesses 50 percent more solar […]



Is America’s fossil fuel empire collapsing?

February 3rd, 2020 at 12:14 pm » Comments Off

Since the close of World War II, the United States has overseen an expanding global order built on fossil fuels. That era has come to an end. Where coal powered the British Empire, and oil powered the American Century, renewable energy technologies are now set to drive the post-American world. Europe’s “Green Deal” represents the […]
