This new laser could make things hotter than the centre of the Sun almost instantly
Posted by Shailesh Prasad in categories: materials, nuclear energy, sustainability
Scientists have proposed a laser model that can could heat materials to temperatures hotter than the centre of the Sun in just 20 quadrillionths of a second. That’s 10 million degrees Celsius almost instantaneously.
The discovery brings us one step closer to the dream of achieving thermonuclear fusion energy — the production of clean, sustainable, and limitless energy using the same process the Sun uses to produce heat.
The challenge in harnessing the energy from thermonuclear fusion is that, as with any form of energy production, you need to get out more than you put in, and heating things to temperatures that rival the centre of the Sun is not easy. Current laser technology has failed to make the heating process efficient enough to make the process worthwhile, but a team from Imperial College London in the UK has come up with a model for a laser than can heat things about 100 times faster than the world’s most powerful fusion experiments.

Cops Called After Tesla Model S Owners ‘Put A Child In The Trunk’
Posted by Shailesh Prasad in categories: habitats, sustainability, transportation
Police waited at the home of a family after someone called in seeing the parents “put a child in the trunk” of the car — someone who clearly wasn’t aware that the Tesla Model S can be equipped with a third row of seats for children.
I stumbled upon this video after comments veteran and Twitter tweeter @_McMike_ tweeted it.

Solar Power To Become Cheapest Source Of Energy In Many Regions By 2025, German Experts Say
Posted by Shailesh Prasad in categories: solar power, sustainability
Solar power still amounts for a small share of net electricity generation around the world. In the USA, for instance, as of December 2014 it was responsible for just 0.45% of the total electricity produced.
Things are changing quite quickly, however, and if the German think tank Agora Energiewende is right, faster than expected.
The main obstacle to a more widespread adoption of photovoltaic so far, has been cost: solar used to be very expensive compared to coal or gas, but, according to Agora — that recently commissioned a study on the subject to the Fraunhofer Institute for Solar Energy Systems — this is no longer true.

Austria’s largest state now gets 100 percent of its electricity from renewables
Posted by Shailesh Prasad in category: sustainability
Lower Austria, the largest of the country’s nine states, announced this week that is has gone all in on clean energy, with 100 percent of its electricity generation for its 1.65-million-strong population now sourced from renewable energy.
In the weeks before world leaders meet for decisive UN climate talks in Paris later this month, the announcement of Lower Austria’s achievement is a beacon of hope amid other grim environmental news – and also a testament to how much the state has put into clean energy production.
“We have invested heavily to boost energy efficiency and to expand renewables,” said Erwin Proell, premier of Lower Austria, at a news conference, as reported by AFP. “Since 2002 we have invested 2.8 billion euros (US$3 billion) in eco-electricity, from solar parks to renewing (hydroelectric) stations on the Danube.”

World’s second vertical forest tower will rise in Switzerland
Posted by Shailesh Prasad in categories: habitats, sustainability
Stefano Boeri Architetti won the bid just one year after completing their first acclaimed vertical forest, or Bosco Verticale, one year ago in Milan. Like its predecessor, the forested tower planned for Lausanne will be covered by shrubs and plants, and will add 3,000 square meters of greenery along its 117-meter-tall facade. The new tower is named “La Tour des Cedres” after the architects’ vision to install over 100 cedar trees on the structure.

Scotland to build world’s largest floating wind farm
Posted by Shailesh Prasad in category: sustainability
The Scottish government has announced that it’s approved the construction of the UK’s first – and world’s largest – floating offshore wind development.
The world’s largest floating wind farm is set to be installed 25 kilometres off the coast of Peterhead at the easternmost point of mainland Scotland. The development, called Hywind, will be developed by Norwegian energy company Statoil and is expected to generate enough electricity to power nearly 20,000 homes.
“Hywind is a hugely exciting project, in terms of electricity generation and technology innovation, and it’s a real testament to our energy sector expertise and skilled workforce that Statoil chose Scotland for the world’s largest floating wind farm,” said John Swinney, deputy first minister.

Researchers create lithium-air battery that could be 10x more powerful than lithium-ion
Posted by Shailesh Prasad in categories: chemistry, electronics, mobile phones, solar power, sustainability, transportation
A new lithium-air battery created by researchers at the University of Cambridge points the way to the ultimate battery packs of the future, its makers say. With a very high energy density, more than 90 percent efficiency and the capability for more than 2,000 recharge cycles, the new test battery could prove an important stepping stone in the development of this essential technology.
If you’re getting tired of announcements about breakthroughs in battery technology, that’s understandable: as they’re so essential to modern life, many teams of scientists are busy working on the problem around the clock, but it’s an incredibly complex area of chemistry. Any new battery has to improve on what we already have, be safe to use in consumer gadgets, and be commercially viable enough to be affordable for manufacturers.
Those are difficult targets to hit, and that’s why many ‘miracle’ batteries have since fallen by the wayside – once the initial lab work is done, proving concepts and scaling up production is very difficult to get right. The potential rewards are huge though, not just for smartphones but for electric cars and solar power, where batteries are essential for storing energy to use when the sun isn’t shining.

Microbiomes could hold keys to improving life
Posted by Matthew Holt in categories: biotech/medical, sustainability
Forty-eight scientists from 50 institutions in the U.S. have formed the Unified Microbiome Initiative Consortium (UMIC). The scientists envision a coordinated effort spanning national cross-institutional and cross-governmental agency support with the goal of driving forward cutting-edge microbiome research, enabling breakthrough advances in medicine, ecosystem management, sustainable energy, and production of commodities. Their proposal was published online in the journal Science on Oct. 28.

The Autopilot is learning fast: Model S owners are already reporting that Tesla’s Autopilot is self-improving
Posted by Julius Garcia in categories: Elon Musk, neuroscience, robotics/AI, sustainability, transportation
During the press conference for the release of the Autopilot, Tesla CEO Elon Musk referred to each Model S owners as “expert trainers” – meaning that each driver will train the autonomous features of the system to feed the collective network intelligence of the fleet by simply driving the electric vehicle on Autopilot.
He said that the system should improve everyday, but that improvements might only become noticeable every week or so by adding up. Just a few weeks after the release, Model S owners are already taking to the Tesla Motors Club forum to describe how the Autopilot is improving…
