This 2,000 trillion watt laser could re-create the Big Bang–and make clean energy

Posted by in categories: cosmology, solar power, sustainability

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts—two petawatts—for an incredibly short duration, approximately a trillionth of a second or one picosecond.

Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.

LFEX is only one of a series of ultra-high power lasers that are being built across the world, ranging from the gigantic 192-beam National Ignition Facility in California, to the CoReLS laser in South Korea, and the Vulcan laser at the Rutherford Appleton Laboratory outside Oxford, UK, to mention but a few.

Transparent Solar Panels Will Turn Windows Into Green Energy Collectors

Posted by in categories: solar power, sustainability

A team of researchers from Michigan State University managed to develop a fully transparent solar panels – a breakthrough that could lead to countless applications in architecture, as well as other fields such as mobile electronics or the automotive industry. Previous attempts to create such a device have been made, but results were never satisfying enough, with low efficiency and poor material quality.

New Research Could Be First Step Toward Buckyball-Powered Quantum Computers

Posted by in categories: biotech/medical, computing, quantum physics, solar power, sustainability

Scientists have characterized the quantum behavior of buckminsterfullerene molecules, also known as buckyballs, with the hope of perhaps one day turning them into miniature quantum computers.

Buckyballs are the Nobel Prize-winning molecules that consist of sixty carbon atoms arranged in a closed, soccer ball-shape. Their peculiar structure bestows them with strange observable quantum properties, and has given them uses in solar panels and even medicine. But a team of scientists from JILA, a research institute run by the National Institute of Standards and Technology and the University of Colorado, has made measurements in preparation for exploiting buckyballs’ quantum properties in even stranger ways.

All-in-one transparent transistors

Posted by in categories: computing, solar power, sustainability

Small tweaks in component ratios generate electronically different layers from the same material to create transparent transistors.

Worldwide demand is growing for transparent conducting oxides for use in , , smart windows and semiconductor-based consumer electronics. KAUST researchers have engineered a zinc-oxide-based that displays tunable electronic properties depending on the tweaking of a new type of dopant.

Transparent electronics rely on indium tin oxide, a transparent and electrically conductive material that has an exorbitant cost due to the scarcity of indium. Zinc-oxide-based materials, such as hafnium-doped zinc-oxide materials, are expected to offer affordable, green and abundant alternatives to . However, hafnium-doped zinc-oxide materials typically require high deposition temperatures and display inadequate performance for real-life device applications.

Scientists Create Liquid Fuel That Can Store The Sun’s Energy For Up to 18 Years

Posted by in categories: solar power, sustainability

No matter how abundant or renewable, solar power has a thorn in its side. There is still no cheap and efficient long-term storage for the energy that it generates.

The solar industry has been snagged on this branch for a while, but in the past year alone, a series of four papers has ushered in an intriguing new solution.

Scientists in Sweden have developed a specialised fluid, called a solar thermal fuel, that can store energy from the sun for well over a decade.

Self-assembling nanomaterial offers pathway to more efficient, affordable harnessing of solar power

Posted by in categories: nanotechnology, solar power, sustainability

Solar rays are a plentiful, clean source of energy that is becoming increasingly important as the world works to shift away from power sources that contribute to global warming. But current methods of harvesting solar charges are expensive and inefficient—with a theoretical efficiency limit of 33 percent. New nanomaterials developed by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York (CUNY) could provide a pathway to more efficient and potentially affordable harvesting of solar energy.
