Researchers say they've designed a floating sea farm that can produce freshwater and crops without any human involvement.

I live on a coast where there’s not a huge amount of farmland and am always interested in solutions that could help us increase our local food security. But I wonder how scalable this particular concept is, and I’m curious about the claims that it uses only solar power and seawater to grow crops. 🤔

I love this TechXplore article about the potential benefits of developing more agrivoltaic farms in Alberta – especially how it seems to have been written specifically to appeal to the conservative provincial government that recently placed a seven-month moratorium on renewables development in the province.

US FARMERS ARE WARMING UP TO AGRIVOLTAICS – an interesting article on the growing support for agrivoltaics, a "specialized field of renewable energy development that co-locates solar arrays with grazing fields, row crops, pollinator habitats, and other forms of agricultural activity."

Makes sense to me! Instead of buying into a false "agriculture vs. renewables" dichotomy, why not use the land for both?

Interesting article in the NYT yesterday on how green technologies are becoming more widespread in the US even in conservative areas where many don't believe in climate change.

According to the article, the key to encouraging green tech adoption (surprise, surprise) is to appeal to people's wallets – not their altruism.

Energy-storing supercapacitor from #cement, water, black carbon

Date: July 31, 2023
Source: MIT

Summary:
Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently #renewable energy, such as #solar or #wind energy.

"'The material is fascinating,' Masic says, 'because you have the most-used human-made material in the world, cement, that is combined with carbon black, that is a well-known historical material -- the Dead Sea Scrolls were written with it. You have these at least two-millennia-old materials that when you combine them in a specific manner you come up with a conductive nanocomposite, and that's when things get really interesting.'

"As the mixture sets and cures, he says, 'The water is systematically consumed through cement hydration reactions, and this hydration fundamentally affects nanoparticles of carbon because they are hydrophobic (water repelling).' As the mixture evolves, 'the carbon black is self-assembling into a connected conductive wire,' he says. The process is easily reproducible, with materials that are inexpensive and readily available anywhere in the world. And the amount of carbon needed is very small -- as little as 3 percent by volume of the mix -- to achieve a percolated carbon network, Masic says.

"Supercapacitors made of this material have great potential to aid in the world's transition to renewable energy, Ulm says. The principal sources of emissions-free energy, wind, solar, and #tidal power, all produce their output at variable times that often do not correspond to the peaks in electricity usage, so ways of storing that power are essential. 'There is a huge need for big energy storage,' he says, and existing batteries are too expensive and mostly rely on materials such as #lithium, whose supply is limited, so cheaper alternatives are badly needed. 'That's where our technology is extremely promising, because cement is ubiquitous,' Ulm says.

"The team calculated that a block of nanocarbon-black-doped concrete that is 45 cubic meters (or yards) in size -- equivalent to a cube about 3.5 meters across -- would have enough capacity to store about 10 kilowatt-hours of energy, which is considered the average daily electricity usage for a household. Since the concrete would retain its strength, a house with a foundation made of this material could store a day's worth of energy produced by solar panels or windmills and allow it to be used whenever it's needed. And, supercapacitors can be charged and discharged much more rapidly than batteries.

"There is a tradeoff between the storage capacity of the material and its structural strength, they found. By adding more carbon black, the resulting supercapacitor can store more energy, but the concrete is slightly weaker, and this could be useful for applications where the concrete is not playing a structural role or where the full strength-potential of concrete is not required. For applications such as a foundation, or structural elements of the base of a wind turbine, the 'sweet spot' is around 10 percent carbon black in the mix, they found.

"Another potential application for carbon-cement supercapacitors is for building concrete roadways that could store energy produced by solar panels alongside the road and then deliver that energy to electric vehicles traveling along the road using the same kind of technology used for wirelessly rechargeable phones. A related type of car-recharging system is already being developed by companies in Germany and the Netherlands, but using standard batteries for storage.

"Initial uses of the technology might be for isolated homes or buildings or shelters far from grid power, which could be powered by solar panels attached to the cement supercapacitors, the researchers say."
