Stuff Matters by Mark Miodownik

It's a book about material science that opens with the narrator getting stabbed! What more could you ask for‽

From the multiple crystal forms of chocolate to the chemical reactions that make cement, Mark combines a love of materials with excellent narrative and takes you through a small sampling of the amazing materials that make our everyday life possible. Stuff matters, indeed.

MIT Scientists May Have Found a Cheap Way of Storing Huge Amounts of #Energy in #Cement

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."

MIT Crack The Concrete Capacitor - It’s a story we’ve heard so many times over the years: breathless reporting of a n... - https://hackaday.com/2023/08/01/mit-crack-the-concrete-capacitor/ #supercapacitor #energystorage #greenhacks #cement

Cement usage dates back to 6,500 BCE. Carbon black was the ink used in writing the Dead Sea Scrolls. What would happen if you put the two together? Engineers recently mixed these two ancient materials in electrolyte-infused water and may have solved a modern energy dilemma. More from Popular Science: https://flip.it/YnvXXF

Was intrigued why #EU and #France are so quick to condemn the coup in #Niger. Usually those sort of crises in Africa, like the current mess in #Sudan, are pretty much ignored by the West. Turns out #Niger has huge mineral wealth especially #Uranium #Gold #Salt #Cement and more ..so seems the French mining companies involved in extraction are worried the coup may mean they can't carry on exporting stuff out.. or the new army rulers may pass minerals on to others willing to pay. Always struck by the irony that #Niger is an extremely poor landlocked country and all that mineral wealth never trickles down to their people. https://en.m.wikipedia.org/wiki/Oil_and_mining_industry_of_Niger

How is Bellingen's "Road Renewal Program" going?
The road reconstruction of Gleniffer Road and diversion (Roses Road) is supposed to be completed by July 2023.

A preview at what once was a scenic forest road has now the charm of a highway.
Apart from the logging scars along it, the road is widened and reveals steep bare gullies where the biodiverse flora and fauna has been eliminated.

The widened shoulders of the 'highway' are mostly lined with prefabricated concrete gutters and culverts. The most fertile layer of the earth is sealed with a thick layer of cement. A rock-hard second skin entombs the living, fertile soil and brings great convenience to fossil fuel enthusiasts on their 'drive'. The road shoulder used to be soft with terrestrial orchids growing on the edges. Now it's given the hard shoulder to channel runoff and pollution down into the bush and the creeks as a fast runoff. It's called taming nature.

Concrete is considered the most destructive material on Earth, it is one of the main producers of carbon dioxide. “If the cement industry were a country, it would be the third largest carbon dioxide emitter in the world with up to 2.8bn tonnes, surpassed only by China and the US.”
https://www.theguardian.com/cities/2019/feb/25/concrete-the-most-destructive-material-on-earth

The channeled cement gutter flow of these hydraulic stormwater structures has negative impacts on stream habitats and biota. Migrating animals find the widened road with slick cement hard to cross. The water quality and habitat become fragmented and degraded.

Soon the speeding vehicles will crack the cement blocks (As can be seen at any NSW roundabout) and they will crumble as rubbish into the bush.

The project doesn't seem to add to Australia's ‘fair share’ to contain global heating or refraining from engaging in extinction.
