Laptop manufacturer Framework commissioned Fraunhofer IZM to do a detailed life cycle analysis on their Framework Laptop 13, which is designed to be upgradeable, repairable, and customizable. The functional unit used in the study is the use of this notebook over 5 years. Although the laptop is modular and repairable, no product failure and thus no repair was assumed. The configuration was assumed to include 16 GB of memory, 256 GB of storage, and two expansion cards with USB-A and USB-C connectors.
Unfortunately, the researchers only calculate the environmental footprint of the laptop in terms of global warming potential and resource depletion, not energy consumption. Nevertheless, the study is interesting for its detailed breakdown of components, with the display and the electronic circuits responsible for the largest environmental damage. The total impact for the Framework Laptop is estimated to be 200 kg CO2e. Almost 70% of this is due to the production phase.

“In 1909, inventor George Cove posed in front of an early rooftop solar panel of his own design for a photograph. One hundred and ten years later, the resulting image was reprinted in the official journal of the US’ most prestigious research institute – but Cove was nowhere to be seen.
Using a range of sources such as newspaper archives and historic city maps, Bellingcat sought to establish the seeming mystery of Cove’s ‘disappearance’ from the photograph. This analysis of archival material from the pioneering days of solar energy tells a cautionary tale about the ease of misattributing historic photos.”

This is a guest post by Mikhesh The Steamer.
It does not have to be just about the winter regarded with apprehension, which did not prove to be as much problematic in Europe at all. In the outlying hills, there is a lack of electricity or gas source. On the other hand, there is usually water and wood nearby. A steam heater can be assembled from things you find in a garbage dump, thrown away in a workshop or in a hobby market.
In a cabin with a fireplace after thirty minutes, the temperature is at best slightly higher, but with steam heating, a T-shirt is enough for that time. You can also spread the steam behind several corners and you don’t have to rely on heat radiation. Wood consumption is equal to a regular fireplace. The difference is in how we deal with its energy.
Steam, that’s what it’s all about.
It is not surprising that many cities used steam for heat distribution in the past. Steam has a much greater heat capacity than water. A supply of 10 liters of water in the tanks is enough for my system to heat a 30m3 brick house from an internal temperature of 5-10°C to 30°C within 3.5 hours. The heat will then pass into the walls and I will last until the morning at 18°C with an outside temperature of 5-10°C. I reach a comfortable temperature within 30 minutes.
I heat these 10 liters of water in pipes which are forming a tank with a total volume of 20 liters. I expect a reserve due to bubbling water and easier regulation. The water itself evaporates according to the intensity of the heating. You will know the appropriate volume after a few tests of your setup and its sound: It manifests itself with a strong bubbling sound.Disadvantages and risks
The system works with minimal pressure, at a rough guess up to 0.3 atmospheres. I solve the risk of overpressure with a plug loaded with a small weight directly on the tank. I covered this part with a metal cover into which I enter through the small door.
Blowing the plug could be unpleasant. It would flood the room with rapidly cooling steam, which is why I cover it. This has never happened in practical use. The steam must have free passage through the pipe at all times. For this reason, I lead the steam through a rubber hose near the ceiling and gradually slope it downwards so that at no point can the condensing water freeze.
It is not necessary to vent the heating steam system. The penetration of steam through the system and the displacement of air is spontaneous. Only at the end does another exhalation occur – plain water, which I take out of the building through the walls. The captured water can be reused.Common use
I pour water before starting the fire, never during it, because I might get scalded. The heating does not retain heat and cools down immediately after the fire burns out or the water runs out. In practice, however, the room stays warm for many more hours. Then I repeat the cycle.Kit sheet
When constructing tanks, you cannot avoid welding. The evaporation containers are sunk into the interior of the fireplace and pass through the plate. They consist of 4 pipes connected in pairs and these are immersed in the combustion space itself, which reduces the internal volume of the fireplace. A tank placed on top of the stove alone would not be efficient enough.
*A fireplace with a cooking plate that will be adjusted for:
*Thick-walled non-galvanized pipes with a wall of 4 mm and a diameter of 40-50 mm for the tank itself in the fireplace. We plunge these through the stovetop and connect them at the top. Their shape therefore resembles a “C”. From there, we lead the couple further to…
*Ordinary water pipes with G thread. An oakum impregnated with vaseline is wound on the screw-threads. Never use a rubber gasket. The steam continues to..
*Brass taps for regulating the given distribution branch. Previously, these taps were used for gas in Central Europe. From here we take the couple out to…
*Thick-walled rubber hoses of the required length. Hoses from compressors for the distribution of compressed air have proven themselves. Subsequently, the steam passes into..
*Old radiator. We are already draining the water from it outside the building.
*All elements must be resistant to 100°C.
*Try to assemble the device in a smaller version in the workshop. You will learn to regulate it and check if it makes sense for you.
I successfully conduct steam up to ten meters away. But it depends on your enthusiasm for experiments. I built my system myself from scraps from work and landfills. Even yours can be unique, where the steam will warm you, also with a great feeling of using discarded items and well-done work.Plan:

- Building and Monitoring a SolarPowered Web Server. [ETH zürich] “In this thesis we focus on building a solar-powered web server. We present existing websites which are fully or partially solar powered, introduce some background about battery state of charge estimation and how to determine the right solar panel and battery size. Reusing components from older projects, we host a static website on an exemplary setup, which is solely solar powered.
Low-tech Magazine’s bike generator powers a record player. No batteries are involved: a buck converter in the control panel keeps the voltage output constant at 12V. Power use is very low and pedaling is easy. Record: Jean-Jacques Perrey et son Ondioline.
We also published a video of our pedal powered video projector.
Human-powered dot-matrix printer. Direct power. No batteries are involved. Directly powering a dot-matrix printer is challenging, especially when printing longer documents. The power demand is variable and can increase suddenly for a short time. You must pedal very fast to anticipate these peaks. If you fail, the voltage drops, the communication between the printer and the laptops breaks down, and the machine prints the document all over again. Capacitors could solve this. A laser printer has a very high power use during startup and is incompatible with a bike generator (or a small-scale solar installation).

“Solar energy often appears a technology without a history, perpetually new and oriented towards the future. This sense of perennial novelty has gone unchallenged by historians, who have generally neglected renewable energy outside the rich world and all but ignored solar energy everywhere. Left to industry professionals, solar history is typically narrated as a triumphalist tale of technical innovation centered in the global North. Such accounts often conflate solar energy with solar photovoltaics (PV) for direct electricity generation… It is tempting to draw a straight line from this innovation to the huge solar PV installations of the twenty-first century; India’s largest, Rajasthan’s US$1.4 billion Bhadla Solar
Park, sprawls across an area the size of Manhattan.”
“Rejecting the eschatology of climate change, such huge mega-projects have reignited the high-modernist idea of progress. They fuse an optimism about the possibilities of science, technology, and human innovation to deliver sustained improvements in economic production and the satisfaction of human needs. In this bright new age, endless rows of solar panels promise to square the circle of economic growth and environmental preservation by providing virtually infinite amounts of clean power for all—and empowerment for women to boot. These utopian ideas, the environmental humanists Imre Szeman and Darin Barney suggest, are coalescing into ‘one of the sharpest and most powerful of ideologies’ today…”
“After the oil shocks of the 1970s, activists in the rich world saw in the sun’s dispersed rays a revolutionary path towards a decentralized ‘energy democracy’, emancipating newly self-reliant citizens from the authoritarian infrastructure of the fossil-fuel-fired electric grid via rooftop solar panels or designer solar homes. Before this point, though, solar energy was more often pigeonholed as something much drabber. A postwar generation of experts cast solar as the ‘poor man’s energy’, to quote a phrase from the period’s best-known international advocate, arguing that the diffuse and intermittent quality of sunlight made it a second-best energy source suited to the scattered rural populations of ‘underdeveloped’ nations… Together these experts imagined solar not as a post-carbon energy source, but a pre-carbon parallel track for those left outside the modern energy economy—a substitute for firewood and dung rather than the abundant and flexible energy of fossil fuels and grid electricity…”
“In the contemporary rich world, going off-grid is framed as a choice. As this earlier episode suggests, though, for much of its history solar energy did not signify the empowerment of the high-tech ‘prosumer’, but spartan compromise with a low-energy past. The physical characteristics of solar energy—available in immense quantity, but diffuse, intermittent, difficult and land-intensive to capture—shaped expert assumptions about its appropriate deployment. In and for the arid tropics, it was seen less as a substitute for fossil fuels than a way to circumvent the expensive expansion of electric grids, marking an admission of the postcolonial state’s inability to deliver public power to the rural majority. Even after independence delivered regimes committed to rapid industrialization, research into solar technologies continued along a low-modernist parallel track. Not simply energy modernization but energy dualism was the pragmatic prescription of the day: large infrastructures for industry and cities, cheap and simple devices for the vast hinterlands of the rural poor. The result was a two-tier energy system, structured by hierarchies of town and country, class, race, and the traditionally gendered division of household labour.”

- The vertical farming bubble is finally popping. [Fast Company] “In a typical cold climate, you would need about five acres of solar panels to grow one acre of lettuce”.
- Seaweed as a resilient food solution after a nuclear war. [ResearchGate] “We find seaweed can be grown in tropical oceans, even after nuclear war. The simulated growth is high enough to allow a scale up to an equivalent of 70 % of the global human caloric demand (spread among food, animal feed, and biofuels) in around 7 to 16 months, while only using a small fraction of the global ocean area. The results also show that the growth of seaweed increases with the severity of the nuclear war, as more nutrients become available due to increased vertical mixing. This means that seaweed has the potential to be a viable resilient food source for abrupt sunlight reduction scenarios.”

Some low-tech computing links:
Quoted from: Couillet, Romain, Denis Trystram, and Thierry Ménissier. “The submerged part of the AI-ceberg.” IEEE Signal Processing Magazine, September 2022.
The energy consumption of a single training run of the latest (by 2020) deep neural networks dedicated to natural language processing exceeds 1,000 megawatt-hours (more than a month of computation on today’s most powerful clusters). This corresponds to an electricity bill of more than 100,000 euros (figures in the millions of euros are sometimes found) and 500 tons of CO2 emissions – that is, the carbon footprint equivalent to 500 transatlantic round trips from Paris to New York. In comparison, the human brain consumes in a month about 12 kWh, i.e., a hundred thousand times less, for tasks much more complex than natural language translation.
Unlike a mere ten years ago and in spite of the improvement in desktop computer capabilities, it is no longer possible today to train a modern neural network on a personal computer (it would theoretically take up to 405 years)… One may object that it is probably not surprising that deep learning algorithms be far less energy efficient than three billion years of biological evolution and that the figures may rather suggest a huge room for potential improvement… This objection would displace the focus of the point made here: in a matter of ten years, the absolute consumption of AI learning skyrocketed to reach levels of hundreds of tons of equivalent CO2 for a single learning task. These levels are at stunning odds with the requirements for the human society to drastically reduce its carbon footprint at a rate of −7%/year, starting today.
Let us pursue on the objection line of argument: “once trained”, the algorithm can be reused billions of times, improving billions of users’ satisfaction and well-being, at a comparatively negligible cost on individual devices; this would make the initial investment, however large, possibly worth it, if not desirable. The argument here makes the untold assumption that AI algorithms do improve human welfare, which is already a debated position, but also hides (i) the fact that practical R&D in AI is a continuous process of trials and errors of deep architectures run on an increasing amount of dedicated servers and (ii) that new algorithms run on up-to-date devices or even dedicated devices, thereby making former equipment obsolete and enforcing the continuous purchase of new terminals.

“You hand pump seawater or polluted water into a bowl. Throughout the day the energy from the sun heats up this water and, instead of evaporating into the atmosphere, it gets trapped in the top section. All the fresh water will then trickle down into this bottom basin and all the impurities of the salt and polluted water stay behind. You’re going to have a left-over salt brine which is going to be a waste resource, but instead of throwing it away, this salt brine goes into the series of seawater batteries around the perimeter that can light a LED strip during the night. At night you can turn on the light and you get an energy source through the salt batteries. And during the day, this is like a skylight, bringing natural light to the interiors.”
“The power of the sun is amazing, and I was trying to copy this hydrological cycle. It can kill 99% of dangerous pathogens, remove salt brine and reduce the need of having to boil your water. I am not necessarily reinventing the wheel; solar distillers have been around for a long time, but a lot of these systems are heavy, expensive to make and with very complicated designs. I wanted to think about one which could potentially be portable and simple to construct, made out of local materials and able to Achieve a higher yield of water.”
“This new design was exactly the same but at a large scale. We created a recipe book that is a step-by-step guide on how you can create this same design using bamboo and local work. It could be flat packed into a bag and deployed very simply and quickly and then attached to a bamboo structure which allows structural rigidity but also a community shaded spot, where you can produce around 18 liters of purified water everyday.”
