Underwater balloons could give us a new way of storing renewable energy

Posted by in category: sustainability

While solar or wind farms are now contributing more energy than ever to the world’s power supply, traditional energy sources are often required at peak times or to supplement renewable sources during dips in availability — at night, for example. So Canadian startup Hydrostor has invented a system of pressurised underwater balloons that can store renewable energy until it’s needed, which could reduce the need for diesel or gas as a back-up source of power.

The company says its solution can last twice as long as the best batteries we have today, and at a much lower cost. The first facility has been set up in Lake Ontario near Toronto, with a series of balloons set 55 metres under the surface of the water and connected to the power grid via a pipeline.

“Compressed air’s been around for 40 years,” Hydrostor CEO Curtis VanWalleghem told Canadian Manufacturing. “It’s finding places to store the air that’s been the problem [and] why it hasn’t been massively adopted. We open it up to thousands more sites because we use hydrostatic water pressure.”

Apple to Introduce 100% Solar-Powered Retail Store

Posted by in categories: policy, solar power, sustainability

Tech behemoth Apple is set to become the first completely solar-powered company in Singapore.

As part of a long-term partnership with Sunseap Group, Apple will draw upon Sunseap’s vast network of more than 800 solar panel-equipped buildings, which will satisfy the energy requirements for the company’s forthcoming 2,500-person corporate campus and retail store operations in Singapore.

According to Lisa Jackson, Apple’s vice president of Environment, Policy and Social Initiatives, the company aims to completely kick its dependence on fossil fuels and rely instead on renewable energy sources for its facilities worldwide.

Bioengineered Shark Fins Could Save 70 Million Sharks

Posted by in categories: bioengineering, biotech/medical, food, information science, sustainability

Each year, an estimated 70 million sharks are killed for their fins. The brutal shark finning process involves cutting off a live shark’s fins and returning the debilitated animal back into the water to die a slow death. Highly valued in traditional Asian medicine and cuisine, the fins can sell for as much as $300 a pound on the black market.

What if an artificial shark fin could remove sharks from the equation completely?

New Wave Foods, a San Francisco-based sustainable seafood company, is developing a bioengineered fin product that could pull the rug out from underneath the shark trade.

This new laser could make things hotter than the centre of the Sun almost instantly

Posted by 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 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 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 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 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 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.
