South Australia to get $1bn solar farm and world's biggest battery
System will include 3.4m solar panels and 1.1m batteries, with operations set to begin by end of 2017

A huge $1bn solar farm and battery project will be built and ready to operate in South Australia’s Riverland region by the end of the year.

The battery storage developer Lyon Group says the system will be the biggest of its kind in the world, boasting 3.4m solar panels and 1.1m batteries.

The company says construction will start in months and the project will be built whatever the outcome of the SA government’s tender for a large battery to store renewable energy.

A Lyon Group partner, David Green, says the system, financed by investors and built on privately owned scrubland in Morgan, will be a “significant stimulus” for South Australia.

“The combination of the solar and the battery will significantly enhance the capacity available in the South Australian market,” he said.

Scientists can use the sun to make seawater safe to drink

  • While access to clean drinking water remains an issue in many parts of the world, there’s no shortage of water on the planet: 97% of Earth’s water can be found in our oceans.
  • Turning the ocean’s saltwater into freshwater is generally an elaborate process that requires a lot of energy, but a team of scientists at Rice University’s Center for Nanotechnology Enabled Water Treatment (NEWT) have created a new method using nothing but sunlight.
  • Now, thanks to researchers at Rice University, an off-grid desalination technology is available requiring only solar energy.
  • The federally funded study, published in the journal Proceedings of the National Academy of Sciences, developed the “nanophotonics-enabled solar membrane distillation” technology, or NESMD. Read more (6/20/17)

Real life solarpunk: neighborhood microgrid in Brooklyn:

Solar Experiment Lets Neighbors Trade Energy Among Themselves

In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door.

The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching. The idea is to create a kind of virtual, peer-to-peer energy trading system built on blockchain, the database technology that underlies cryptocurrencies like Bitcoin.

Solar Cell Self-Repairs Like a Plant

When leaves are damaged by intense ultraviolet light, they’re able to repair themselves, constantly producing new cells to replace the damaged ones. If only solar cells could do the same thing, they’d last a lifetime. Luckily, scientists have found a way to replicate that natural process using proteins, bacteria and water. These solar cells can’t compete with silicon cells just yet – it will take decades of research to improve them – but it’s an impressive start that could improve ‘artificial leaf’-type solar cells even further.

Dual-function nanorod LEDs could make multifunctional displays

Cellphones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, thanks to new LED arrays that can both emit and detect light.

Made of tiny nanorods arrayed in a thin film, the LEDs could enable new interactive functions and multitasking devices. Researchers at the University of Illinois at Urbana-Champaign and Dow Electronic Materials in Marlborough, Massachusetts, report the advance in the Feb. 10 issue of the journal Science.

“These LEDs are the beginning of enabling displays to do something completely different, moving well beyond just displaying information to be much more interactive devices,” said Moonsub Shim, a professor of materials science and engineering at the U. of I. and the leader of the study. “That can become the basis for new and interesting designs for a lot of electronics.”

Printable solar cells just got a little closer

A U of T Engineering innovation could make printing solar cells as easy and inexpensive as printing a newspaper. Dr. Hairen Tan and his team have cleared a critical manufacturing hurdle in the development of a relatively new class of solar devices called perovskite solar cells. This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator.

“Economies of scale have greatly reduced the cost of silicon manufacturing,” said Professor Ted Sargent, an expert in emerging solar technologies and the Canada Research Chair in Nanotechnology. “Perovskite solar cells can enable us to use techniques already established in the printing industry to produce solar cells at very low cost. Potentially, perovskites and silicon cells can be married to improve efficiency further, but only with advances in low-temperature processes.”

Technology doesn’t tend to just disappear: what is the social network of solar punk? How do we order and deliver goods? What do cars and public transport look like? What is our power grid? Are personal and street lights now bioluminent, or are they charged solar pieces? Are cell phones and computers integrated into our brains, updated frequently? What are advances in Wi-Fi technology? Are there people who prefer to go all natural, forgoing implants for suspicion of technology or religious reasons? What do robotics look like in a solar punk society? Are they humanoid, passing as people? Do they have rights? Are robotics used to supplement human bodies, like with functional prosthetic limbs and replacement parts? Or do we slowly eschew robots in favor of technology to grow whole new body parts, to create new organics for ourselves?

Solar Panel Goals

So as you might have seen, I got portable solar panels a couple days ago, and a big ol’ power bank yesterday (all told, this investment was $110, including shipping, if you were wondering).

I did this for a number of reasons, the most significant being that I want to be able to demonstrate, any time and anywhere, the sheer power and awesomeness of solar energy. These panels are roughly the size of a sheet of paper, fold in half for easy transport, and have attachment rings to hook onto backpacks, car windows, decks, etc. You can literally take them anywhere, open them up, and immediately begin charging.

If we can show people how affordable, powerful, and just overall exciting this is, we can change how they perceive renewables, Maybe even convince them to invest in their own household renewable technologies!

My second mission is to break my portable device charging dependency. Starting on May 31st, all the power I put into my phone came from sunlight. As of 8:30am on June 1st, 100% of the power stored in my phone was solar energy. The first real goal I have is to go a full month without plugging my phone into a wall, ever. Not even when my phone is dangerously low….which it shouldn’t reach, because…

Of the power bank you see in this picture! The black box in front of the panels. Fully charged, it stores enough energy to charge my phone about 7 times. The solar panels themselves have a storage device capable of holding about 3 charges. Combined, that’s 9-10 full charges for my phone–about a week’s worth, maybe more.

The other thing about the solar panels is that when in full sunlight, with my phone plugged in, they generate enough energy to recharge about 1% per minute. You know, just about the same rate of charge that a wall charger provides. This isn’t a guess, or something I read in the manual. This is what I measured yesterday and this morning when I plugged my phone into the panels. It’s literally just as good, and even better than a wall plug. Because wherever there is sunlight, there is power. No more searching under tables at the coffee shop, or fighting people at the airport. It even works through windows (as seen in this picture!)

The solar panels you see here, from iNiCE, cost me $55. The power bank was $50. Unless I decide to go live in a cave for the rest of my life, I will literally have unlimited energy.

Future goals include getting my laptop off the charging grid, too, and providing energy to my family/friends when needed to reduce THEIR energy consumption. It might be just nickles and dimes at a time, but it adds up.

I’m just gonna say it: I’ve had these solar panels for two days, and they’ve already proven to be an exciting, worthwhile investment, with promises for what the future holds!

Concept for Armored Soul Configuration

DSI-LRDRN E-SMGH ‘Executioner’

20XX

The pilot is referred to as ‘the Executioner’ by both elite pilots and common infantry. One glance at the infamous machine and its unorthodox weaponry would suggest this soul as being twisted and brutish–the gold-plated allegory of raw, crushing force.

The front of the frame shows little in the way of movement ability, but multiple verniers on its backside and between the plating, along with thrusters installed on the Capital Hammer allow for deceptively fast movement and attack patterns. The machine uses a prototype version of the old solar technology from the Golden Kingdom, and it can only be deployed at very close range.

The pilot’s past lies in bloody mercenary work and varying periods of imprisonment. One among the Order of Knights of the Golden Kingdom recognized his abilities and, in exchange for unwavering loyalty to the kingdom, was granted a rank in this order. It is almost entirely thanks to this combination of speed, precision, and power that not one soul has been able to enter the Golden Kingdom as of yet.

Water-Based ‘Artificial Leaf’ Produces Electricity

Solar cells that mimic nature could be less expensive and more environmentally friendly than current solar technology. In 2010, researchers at North Carolina State University developed water-gel-based solar devices that are essentially ‘artificial leaves’ that couple plant chlorophyll with carbon materials, mimicking the way nature harvests solar energy. They’re flexible, which is a huge improvement over today’s problematically brittle cells.

So I’ve been binging on solarpunk stuff this morning and something occurred to me. I am behind this 10,000%, but I feel the need to point out that while we strive for sustainable technology, agriculture, architecture, etc., we need to advance eco friendly batteries.

Currently, solar panels work by charging a battery which is used to power whatever you need powered. Those batteries are about as advanced as your cellphone battery, using lead-acid and sulfuric acid, both of which are toxic and corrosive. There have been some experiments done with biodegradable batteries, and eco-friendly options exist, but not at the capacity needed for massive solar panels all over the world. We need to pump more money and attention into that idea, so that all other solar-based technology can be actually sustainable.

It is important to view knowledge as sort of a semantic tree - make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details. Otherwise there is nothing for them to hang on to.
