Smart(er) switch

My new(ish) living room smart switch

I bought a smart switch to help with the somewhat weird layout of our living room at the time. I had intended to reflash it with Open Source Software so I wasn’t sending data to some nameless company with remote servers that would render my switch useless if I lost connection to them. I had used the Tasmota firmware on another cord-based switch before and it proved simple and reliable.

There are a handful of different chips in these inexpensive smart wall switches. Some use the maker-favorite ESP chip, and others use a chip from a company called Tuya. The ESPs are usually easy enough to reflash after adding a programming header, but the Tuya chips require connecting directly to the pins on the chip. Someone designed a 3d printed jig to help with this, but I wasn’t able to print one that was usable which led to the long break between purchase and use.

In December, I found the switch again and decided to give it another go. I found that there was now a tool called Tuya Convert that allows you to change the firmware over your home WiFi network. With things approximately 1000x simpler, I was able to get the switch working with the Tasmota firmware in just an evening.

The firmware includes an option to turn the light on or off at a particular time, including a set number of minutes before or after sunrise/sunset. The device does need a little extra configuration to know its time and location, but it has been working reliably since the initial setup.

One of the reasons I prefer switches to smart bulbs is that everyone already knows how to use a wall switch. When I first installed the firmware, the physical switch function didn’t work, so I had to ask Alexa to turn it on or off instead of being able to do it myself. After some digging around on the Tasmota list of supported devices, I got it working by modifying a profile from a switch that was actually supported. I strongly support going with a supported switch to save yourself the headache. I saw they even had some options now with Tasmota from the factory, which is probably the best option. As the project is Open Source, I was able to suggest an update to the database with the settings I found working for this particular switch in case anyone comes across it again in the future.

I’m happy with the switch since I can turn it on or off from other parts of the house or turn the light on or off while I’ve got my hands full. Our kitchen and living room are attached, so it’s especially helpful when I’m cooking or doing dishes.

Do you have any smart appliances or lighting in your home? Do you find it helpful, or are smart IOT gadgets just something that’s unnecessary to solarpunk life? Let us know below!

Energy: A Human History – Review

1 Reply

Energy: A Human History by Richard Rhodes chronicles the development of industrial power sources with a focus on the innovators and scientists who developed the technologies. Starting in Elizabethan England with none other than William Shakespeare, Rhodes weaves a compelling tale of the western world’s energy sources starting with the transition from wood to coal in 1600s Britain.

The book paints the picture of the industrialists we now love to hate as human beings with hopes, dreams, and failings. It can be hard to remember after so long that James Watt and Henry Ford were once actual, living beings, and that they had hoped to make the world a better place with their inventions.

Drawing from many primary sources, Rhodes has lifted many gems of what the people of the time found concerning about these new technologies. With references to coal as “the devil’s excrement,” and many other such epithets, one might wonder why such dirty fuels ever became predominant. As Rhodes points out in the book though, industrialization with coal and other fossil fuels led to a near doubling of human life span and a higher standard of living. Rhodes does devote a fair bit of the book to the work that various towns and nations did to combat the air quality problems associated with the use of fossil fuels to varying degrees of success.

Concerns were not just constrained to air quality. Safety of steam engines, locomotives, and automobiles were a great concern of the time. As to cars, we have definitely come out on the wrong end of that technology with many US cities being designed for cars instead of people, but some of the concerns for trains seem amusing now as this quote Rhodes found shows.

“What can be more palpably absurd and ridiculous,” asked a reviewer for London’s Quarterly Review who favored a plan for a railway to Woolwich, “than the prospect held out of locomotives traveling twice as fast as stagecoaches! We should as soon expect the people of Woolwich to suffer themselves to be fired off upon one of Congreve’s… rockets, as trust themselves to the mercy of such a machine going at such a rate… We trust that Parliament will, in all railways it may sanction, limit the speed to eight or nine miles an hour, which… is as great as can be ventured on with safety.”

If you are firmly anti-nuclear, the end of the book will not be to your liking. As a cautiously optimistic person regarding nuclear energy, I feel the author may be a bit nuke-happy. Many of his points in favor of nuclear base loads are legitimate, however. Current nuclear generation technologies have been shown by IPCC and NREL (National Renewable Energy Laboratory) analysts to have a carbon footprint similar to wind and solar. With many cities and states looking at 100% renewable commitments, including nuclear as a base load to counter the intermittency of renewable sources seems reasonable in geologically stable areas. Unfortunately, when states set “renewable” goals for their energy goals, they sometimes include waste incineration, which is both gross and bad for local air quality.

Beside its overly-western focus, the other main shortcoming of the book is its relatively light treatment of renewable technologies. There was very little regarding solar, hydro, and wind, and I’m not sure if geothermal was mentioned at all. I suspect that this was due to a desire of the author to focus on the technologies that were the primary drivers of industrialization. Regardless, I think this is a good treatment of the subject of modern industrial energy sources and the people who brought them to fruition.

The Green New Deal and Solarpunk

Leave a reply

If you’ve been following US Politics, you may have heard rumblings of a Green New Deal. My first encounter with the term was during the 2012 Presidential Election when Jill Stein noted the necessity of mobilizing the nation to combat climate change and improve the economy at the same time. Seven years later, the US has made little progress at the federal level in addressing climate change. The few exceptions to this are being contested by the Trump administration including CAFE standard improvements and the Clean Power Plan. With the IPCC’s October 2018 report saying we have 12 years to get our act together, it’s time to declare war on climate change.

For a very in-depth look at the Green New Deal, check out David Roberts’ piece at Vox. There are three main criteria for the GND as outlined by Representative-elect Alexandria Ocasio-Cortez and reiterated by Sunrise Movement on Twitter:

As a solarpunk, it’s hard to argue with the goals of the Green New Deal. As a pragmatist, it’s hard to see much happening in the current political climate in regards to real climate action at the scale of the Green New Deal. It isn’t all gloom and doom though, as there does seem to be a glimmer of hope for the two biggest policy changes that I think will bring us closer to a solarpunk future: a price on carbon, and term limits for Congress.

Pricing Carbon

As Sara E. Murphy points out in her piece at Green Biz, while the Green New Deal is the attention-getting piece of legislation, we’re likely to see significant push-back from the Republicans in Congress. A carbon tax or cap-and-trade scheme is starting to see some traction on both sides of the aisle, however, such as the Energy Innovation and Carbon Dividend Act of 2018 with it’s mix of Republican and Democratic sponsors. Putting a price on carbon is the most straightforward way to get the private sector reducing emissions of carbon dioxide here in the US. Even many Libertarians see the logic in accounting for externalities, particularly when they impact people’s rights to the commons of the atmosphere.

While the federal government in the US has fallen behind in climate leadership, California has already enacted a cap-and-trade system for carbon dioxide emissions, and there are many state and local initiatives working to stay on track with emissions targets set by the 2015 Paris Agreement. One that is particularly exciting is the United States Climate Alliance, which will be adding even more members following the 2018 midterm elections.

Term limits for US Congress

Why am I including a possible Amendment to the US Constitution as something to help us reach a solarpunk future? This video from Term Limits for US Congress is a more detailed answer, but the long and short of it is that Congress no longer represents the people. With some recent polls showing that even the majority of Republicans support environmental protection and climate action, it’s increasingly clear that the old guard on Capitol Hill is out of touch with the majority of Americans. The newest members of Congress are a closer match to the actual demographics of the country, but we still have a long way to go to having true representation in DC.

There are two mechanisms for passing a Constitutional Amendment in the United States. The first requires both the House and the Senate to approve the Amendment by a supermajority, at which point the Amendment must be ratified by 38 of the 50 states. Senator Ted Cruz has proposed a Constitutional Amendment that would limit Senators to two terms and Representatives to three terms, but getting career politicians on The Hill to fire themselves seems like a tough sell.

The second way to pass an Amendment, as laid out in Article 5 of the US Constitution, is for 34 states to call for a convention regarding a specific topic where they hammer out the proposed Amendment. Once ratified by 38 of the 50 states, it becomes part of the Constitution just like any of the other Amendments that have been enacted.

My wish list for 2019 would be that we get a price on carbon and term limits for Congress. It might be a tall order, but solarpunks are an optimistic lot, so there is still hope in the face of the strong institutional opposition to climate action.

Why we can do better

I recently went on a gold mine tour in Virginia’s Lake Anna State Park. At one of the stops, the ranger was talking about the various technologies people in the area had used to extract gold from the river. When she started talking about the steam-driven stamp mills, she said that a miner would have about 60 days of operating the machine before they went completely deaf. One of the children in the audience asked, “Why did they make the machine if it would make the miners go deaf?”

My first reaction was to think this was a silly question, since obviously the people who ran the mine would want to extract the most gold for the least cost regardless of what that meant for workers. The more I thought about it though, the more I realized that this was a really good question. Is gold really so important that people should be risking their lives or their well-being for it? The ranger also told us that all of the gold mines in the United States had been shut down during the world wars since gold wasn’t a strategic material.

What things are really so important that people should risk their life and limb to obtain them? Any animal needs water, food, shelter, and space for their habitat. It would make sense that these are the things we should focus our efforts on and be willing to sacrifice to ensure. These are the things afforded travelers by the guest rights present in many ancient cultures.

At our current place in history, it seems we’ve forgotten these basics. We send people into dangerous mines for minerals that could be reclaimed (often at great monetary cost) as corporate capitalism makes human life less worthwhile than inexpensive resource extraction. I don’t suggest we go back to the Dark Ages, but I am suggesting we rethink what we value. If a job is important enough that it needs doing, we should be setting a living wage for the people doing it.

Putting people above profits will give us a more equitable world, one of the most important parts of a solarpunk society. To truly have a free market, you have to take as many variables into account as possible. Externalities like pollution and loss of human life should be factored into doing business and not just laid at the feet of the government or individual citizens. That’s not a free economy. That’s corporate welfare.

What other externalities concern you? What do we need to consider when designing our economies?

Solarpunk and energy fragility

Leave a reply

A couple weeks ago we were treated to a 9 hour power outage here at home. It wasn’t a terrible experience, but it did remind me of how fragile our infrastructure really is. In the US, the American Society of Civil Engineers puts together a “report card” for infrastructure every four years. In 2017, US energy infrastructure scored a D+.

Large sections of the grid are reaching the end of their design life, and we don’t have enough funding dedicated to upgrading and replacing parts. Decentralized power generation such as solar and wind will help immensely as the power can be generated closer to where it’s used. This means when one part of the grid goes down, there still should be electricity in the others. Some communities have started investing in their own local grids, and you can convert some of your usage to solar even if you rent an apartment.

Since one of the main parts of solarpunk for me is decentralization, both political and technological, I think that having a more decentralized grid will lead to more resilient communities and services. Does your community have any programs right now to help people become less reliant on the grid? Let us know below!

 

GoSun Fusion oven on Kickstarter

Want to cook with the sun?

4fabbbe344a1fb6238d2f1df2348cdb2_original

GoSun has been making solar ovens for awhile and is now Kickstarting the GoSun Fusion which can use either solar power or electricity to cook a meal for up to five people. I don’t have any affiliation with GoSun, but their ovens have pretty good reviews, and I really like the idea of being able to cook with the sun both day and night.

I think this oven looks like it would be really awesome if you have an off-grid house or do a lot of campground camping where you have a base camp. It’s probably too big to use for backpacking, although it does look like GoSun has a smaller model that might work for that, the GoSun Go.

Do you have a solar cooker? Do you know of any good DIY plans that we should try out here at Solarpunk Station? Let us know below!

Solarpunk transformative living

Leave a reply

Solarpunks should definitely check out LifeEdited, started by Treehugger founder Graham Hill. Their first prototype apartment was built in NYC to see how much life you could get out of a relatively tiny apartment. They managed to reduce their impact on the environment by fitting a 2-bedroom apartment with room to serve a dinner party of ten in a 420 square foot space!

After an even smaller second apartment, they’ve designed an entire off-grid house with solar panels, battery backup, composting toilets, and since it’s in Maui, plenty of room for surfboards. While all three projects had substantial funding, the underlying techniques used to enhance the spaces are applicable anywhere and and serve as a great inspiration on how to more efficiently use the space you have.

All of the furniture in the apartments and house is multi-purpose. In a place like New York City, where price per square foot is so high, even for renting, the high price of a transforming Murphy bed/couch from Resource Furniture would quickly pay for itself, although if you’re more inclined to DIY, then you can find Murphy bed kits for $200-300 without the mattress.

Transforming tables and folding chairs are often easier and cheaper to get. We have a dining table with leaf that we can remove when we want to save space. This gives us enough room when family visits for eating, but the ability to have a smaller table when it’s just two or three of us. My parents have a gate-leg table for family visits with chairs that fold up and fit inside the table so it only takes a small amount of room unless needed. A gate leg table and a Murphy bed would be great if you like having friends over for dinner but live in a small space.

I shouldn’t find the composting toilet in the bathroom to be the most exciting feature, but I do.

Composting toilets eschew the current trend of flush toilets by treating waste in a waterless or low water manner, composting the waste instead of using clean water to flush it miles away to a treatment facility. I’ve mostly seen them used in off-grid cabins and tiny houses to date, but hope that systems with remote waste collection will allow for usage in more urban environments in the future. Especially in the U.S. where we treat all of our water to drinking water quality (a whole post in itself), using clean water to flush waste back to be treated again is just silly.

Do you have any cool pieces of transforming furniture? Have you used a composting toilet? Let us know about any pluses or pitfalls below, and thanks for stopping by!
