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.

Is Sarah Snyder the solution to our planet's energy problems?

It’s estimated that one look from Sarah Snyder generates more energy than a dozen solar panel arrays.

This liquor store was in a blackout, but when Sarah Snyder threw this pose, everything powered on. (Including that ATM, which wasn’t plugged in) 

One side-effect of the all the energy that Sarah Snyder generates is that her body outputs around 500 BTUs per minute, which is a contributor to global climate change. 

Whenever Sarah Snyder rides in an electric vehicle, the battery becomes permanently charged, defying all known scientific theories. 

Sarah Snyder generates so much energy that the clothing she wears is radioactive afterward, and has to be deposited in lead caverns underground.

Since 2010, all space launches have been powered by a single selfie of Sarah Snyder (the same photo has been reused for each launch, with apparently no reduction in power). This new form of energy has been dubbed “selfie power." 

Policy centers are concerned about the economic disruption that Sarah’s limitless source of power will have on unemployment in the energy sector. For example, after Sarah Snyder struck this pose, the national grid was overloaded with electricity, fracking went out of business, and about half of Canada caught on fire.

what the heck is solar punk?

It’s a proposed genre of science fiction & art that I’m currently obsessed with. Here’s a link to a Tumblr post about it that received a lot of attention, and here’s a link to the article I first saw about it, “Solarpunk: Notes toward a manifesto.” 

It’s about embracing alternative energy, renewable resources, urban agriculture, as well as the artistic integration of these principles into aesthetic experience. One of the examples that gets kicked around a bunch is stained-glass windows that are solar panel arrays. Art Nouveau is a popular proposal for the style and philosophy that the work / movement might draw on.

I’m excited about it because it’s the first concrete proposal I’ve seen this century for a way to write sci fi that isn’t about how the world is about to end, or just finished ending. Optimistic near-future SF is important, and currently basically absent.

A stunning view of the planet at night from an altitude of 240 miles. The lights of Moscow, Russia are near picture center and one of the station’s solar panel arrays is on the left. Aurora and the glare of sunlight lie along the planet’s gently curving horizon.

Electrodialysis Could Help India's Drinking Water Problems

by Michael Keller

The first thing that might come to your mind when asked to think about water in India might be “monsoon,” the drenching season of downpours that is currently plaguing the country with devastating floods.

But India’s bigger problem with water is a deficit, not a surplus. According to UNICEF, the country is home to 16 percent of the world’s population and only 4 percent of its water resources. Demand is already outstripping supply, and surface water sources are being continually degraded from many different sources of pollution. 

That leaves the nation’s groundwater supply to shoulder a heavy burden for a thirsty populace. While these underground sources are considerably cleaner than water that flows on the surface, they also contain significant amounts of dissolved salts that make them brackish. A recent report in the Journal Desalination claims that 60 percent of India’s land area sits atop such brackish waters. 

These saline impurities leave the water less salty than the sea, but relying on it as a source of drinking water can still lead to long-term health impacts. Salty groundwater also doesn’t taste very good, pushing people to look for other sources that might actually be more harmful. What’s more, reverse-osmosis plants, the typical infrastructure used to purify saline water to make it fit for drinking, need a connection to the electric grid for power. Many parts of rural India lack such a power supply.

A recent report by MIT engineers analyzed the problem and found that an acceptable technological solution exists to clearing brackish waters of dissolved salts without needing a nearby electric grid.

Alien Post #13: Dyson Spheres

Geoff Marcy, an astronomer at U-Cal Berkeley, discovered 70 of the first 100 exoplanets ever found.

He worked with the robotic telescope Kepler as it harvested light from distant worlds and recently he put together a project for Kepler that has interesting implications.

The Kepler telescope watches as a stars brightness dims due to a planet moving in front of it as it orbits. This is how it finds planets. Marcy decided that assuming there are hyper-advanced alien civilizations out there somewhere, it’s possible we aren’t looking entirely at planets, but something far less natural:

Marcy was awarded $200,000 from the Templeton Foundation to search for things called “Dyson spheres”.

What are those you ask? Imagine a solar panel. Now imagine a huge array of solar panels. Now imagine a huge array of solar panels wrapped around a star. Now imagine how much energy that would generate.

These theoretical machines would be wrapped around entire stars and could produce the energy needed to support a super advanced, possibly interstellar, civilization.

Using his grant money, Marcy is going to lease time to use the Keck Observatory and develop methods to hunt for things like Dyson spheres that would indicate advanced extra terrestrial intelligence. This all while scouring through the Kepler data, looking for aberrations that would indicate we may not be looking at a planet after all.

Solar array panels on Russian segment of Space Station

Solar array panels on the Russian segment of the International Space Station and a blue and white part of Earth are photographed by an Expedition 38 crew member while the crew watches for the arrival of the ISS Progress 54 cargo spacecraft, loaded with 2.8 tons of food, fuel and supplies for the station crew. The new Progress, which docked to the station at 5:22 p.m. EST on Wednesday, Feb. 5, is loaded with 1,764 pounds of propellant, 110 pounds of oxygen, 926 pounds of water and 2,897 pounds of spare parts, experiment hardware and other supplies. Progress 54 is slated to spend about two months docked to the complex before departing to make way for ISS Progress 55.

Two sets of CubeSats were deployed late Wednesday, Feb. 26 and early Thursday, Feb. 27, leaving just two more launches to go of the 33 CubeSats that were delivered to the station in January by Orbital Sciences’ Cygnus cargo ship. The latest CubeSats were sent on their way at 8:50 p.m. EST Wednesday and 2:40 a.m. Thursday. CubeSats are a class of research spacecraft called nanosatellites and have small, standardized sizes to reduce costs. Two final batches of CubeSats are set for deployment at 11:20 p.m. Thursday and 2:30 a.m. Friday, but more are scheduled to be delivered to the station on the second Orbital commercial resupply mission in May.

Astronaut Kathy Thornton jettisons a damaged solar array panel into space during Hubble’s first servicing mission, STS-61, in December 1993. When the solar panels were replaced, astronauts found a bend in the casing of this panel. The panel couldn’t be returned safely to Earth, and was released into space. Earth’s gravitation pulled the jettisoned panel toward Earth’s atmosphere, where it entered and ultimately burned up.

Hubble’s solar panels generate power for the telescope by converting sunlight into electricity. The arrays power the telescope and charge its batteries while Hubble is in sunlight. When Hubble moves into the dark portion of its orbit, the batteries provide power.

In this April 25, 1990, photograph taken by the crew of the STS-31 space shuttle mission, the Hubble Space Telescope is suspended above shuttle Discovery’s cargo bay some 332 nautical miles above Earth. The Canadian-built Remote Manipulator System (RMS) arm, controlled from in-cabin by the astronaut crew members, held the huge telescope in this position during pre-deployment procedures, which included extension of solar array panels and antennae.
