Welcome indoors, solar cells

Posted by in categories: internet, particle physics, solar power, sustainability

Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.

As the internet of things expands, it is expected that we will need to have millions of products online, both in public spaces and in homes. Many of these will be the multitude of sensors to detect and measure moisture, particle concentrations, temperature and other parameters. For this reason, the demand for small and cheap sources of renewable energy is increasing rapidly, in order to reduce the need for frequent and expensive battery replacements.

This is where organic solar cells come in. Not only are they flexible, cheap to manufacture and suitable for manufacture as large surfaces in a printing press, they have one further advantage: the light-absorbing layer consists of a mixture of donor and acceptor materials, which gives considerable flexibility in tuning the solar cells such that they are optimised for different spectra – for light of different wavelengths.

USA’s First “Pick-Your-Own Hemp” Field Opens in Maine

Posted by in categories: food, neuroscience, sustainability

Customers can trim branches for $35 a pound or cut down the whole plant (like a Christmas tree) for $25 a pound. In a video of the field’s grand opening, a customer buys a 15-pound plant for almost $400.

That may sound pricey, but considering you’re lucky to find most refined hemp products for $25 an ounce, it’s a bargain, according to the farm’s customers, who tell the local newspaper, they’ll be using the plant’s flowers to make CBD oil, lotions and tinctures for pain, anxiety, depression and insomnia.


Instead of conventional row crops, they now grow one of the most lucrative plants on the planet.

Neutrinovoltaic Technology is Opening Up the Future of Sustainable Energy

Posted by in categories: climatology, particle physics, solar power, sustainability

BERLIN, August 21, 2019 (Newswire.com) — The Neutrino Energy Group cooperates with a worldwide team of scientists and various international research centers, which deal with application research, the conversion of invisible radiation spectra of the sun, among other things the neutrinos (high-energy particles, which ceaselessly reach the earth) in electric power.

Is renewable energy hurting consumers?

During the last decade or so, consumers around the world have been encouraged to install solar panels on top of their houses. In certain climates, these rooftop photovoltaic installations can more than cover the electrical needs of an individual home, and many solar-equipped houses feature photovoltaic systems that wire directly into the grid. At times when the home has excess solar-generated electricity left over, this energy feeds back into the grid and helps out with the electricity needs of other energy company customers.

Congratulations to 2019 Nobel Prize in Chemistry Winners John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino

Posted by in categories: chemistry, computing, mobile phones, sustainability, transportation

The 2019 Nobel Prize in Chemistry was awarded to John B. Goodenough (The University of Texas at Austin), M. Stanley Whittingham (Binghamton University, State University of New York), and Akira Yoshino (Asahi Kasei Corporation and Meijo University) “for the development of lithium-ion batteries”. With the creation and subsequent optimization of lithium-ion batteries to make them more powerful, lighter, and more robust, the seminal work of Goodenough, Whittingham, and Yoshino has had a profound impact on our modern society. This ubiquitous technology has revolutionized our daily lives by paving the way for portable electronics and made renewable energy sources more viable. While attempts to improve the performance of batteries continue, the lithium-ion battery has remained the world’s most reliable battery system for more than 40 years. The three winners will each receive an equal share of the roughly $1 million award. At 97, Goodenough is now the oldest person ever to win the Nobel Prize.

“A long-awaited recognition for the creators of lithium-ion batteries has come true. The electrochemistry and material science communities – and the greater chemistry community as a whole – are excited to hear the news of the 2019 Nobel Prize award to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino for their pioneering contribution to lithium-ion batteries,” said ACS Energy Letters Editor-in-Chief Prashant Kamat. “As we all know, the lithium-ion battery has revolutionized our modern-day activities. From mobile phones to laptops and from electronic gadgets to electric cars, these storage batteries have become part of our everyday life. We at ACS Publications are excited to be part of this celebration.”

Whittingham laid the foundation of the lithium-ion battery while working at Exxon in the 1970s. During that time, the oil crisis in the United States was ongoing, and there was a strong drive to develop methods of energy storage and transport that did not rely on fossil fuels. Whittingham developed a 2V lithium-ion battery based on a titanium disulfide cathode and lithium metal anode. While a seminal contribution to the advancement of the lithium battery, adopting Whittingham’s system for everyday use would be limiting due to the high reactivity of lithium metal and risk of explosion.

Ever heard of an anti-solar panel? Here it is

Posted by in categories: solar power, sustainability

In a recent paper (Generating Light from Darkness), published on Joule, Stanford University researchers Aaswath P. Raman, Wei Li, and Shanhui Fan are reporting the successful creation of a device that is able to generate electricity by exploiting the difference of temperature that can be established during the night between the surrounding air and the surface of the device that is cooling itself by emitting infrared radiations towards the night sky.

The possibility to generate electricity by exploiting thermal difference is not new, what is new here is the idea of creating a temperature difference by having part of the device radiating energy into the outer space.

Lab-grown meat could be on store shelves by 2022, thanks to Future Meat Technologies

Posted by in categories: food, sustainability

Are consumers ready for meat grown in a lab?

Companies like Memphis Meats, Aleph Farms, Higher Steaks, Mosa Meat and Meatable are all trying to bring to supermarkets around the world meat made from cultivated animal cells, but the problem has always been the cost.

Now, Future Meat Technologies has raised $14 million in new financing to build its first pilot manufacturing facilities to bring the cost of production of a cell-made steak down to $10 per pound — or $4 if the meat is combined with plant-based meat substitutes.

Laser could be used to make rain on demand

Posted by in categories: particle physics, sustainability

Circa 2010


Ultra-fast pulses from a powerful laser can create droplets of water out of thin air, according to a new study. With the right conditions and large enough droplets, the researchers say, the technique could be used to make rain on demand.

Rain forms when water condenses around tiny particles in the atmosphere. Most of the time, dust or pollen do the job, but humans have long attempted to speed the process by seeding clouds with chemicals like silver iodide. Those chemicals provide the so-called “condensation nuclei” that trigger the consolidation of water into raindrops.
