Stored as heat in a bath of molten material, extra energy could be tapped when needed.
Researchers at Massachusetts Institute of Technology (MIT) discovered that adding a highly conductive substance called carbon black to a water and cement mixture created a construction material that could also serve as a supercapacitor.
Supercapacitors can charge and discharge extremely efficiently but are typically not capable of storing energy for long amounts of time. So while they lack the functionality of traditional lithium-ion batteries – which are found in everything from smartphones to electric cars – they are a useful method of storing excess electricity generated from renewable energy sources like solar and wind.
Since first unveiling the technology last year, the team has now built a working proof-of-concept concrete battery, the BBC reported. The MIT researchers are now hoping to build a 45-cubic-metre (1,590-cubic-feet) version capable of meeting the energy needs of a residential home.
In advancing sustainable waste management and CO2 sequestration, researchers have crafted reactors that mineralize carbon dioxide with fly ash particles. This avant-garde technique is set to offer a sustainable and lasting solution to the pressing issue of greenhouse gas emissions, repurposing an industrial by-product in the process.

National University of Singapore (NUS) chemists have developed hexavalent photocatalytic covalent organic frameworks (COFs) which mimic natural photosynthesis for the production of hydrogen peroxide (H 2 O 2), an important industrial chemical.
The conventional method of H 2 O 2 production involves using anthraquinone as a catalyst to convert air and hydrogen into H 2 O 2. However, this process requires substantial energy, costly noble metal catalysts, high-pressure hydrogen gas and hazardous solvents. Artificial photosynthesis of H 2 O 2, resembling the natural photosynthesis process with the use of sunlight as an energy source and abundant water and air as feedstocks, presents a sustainable and promising alternative to the conventional anthraquinone process.
However, such an artificial system faces three key challenges: insufficient charge carrier generation and fast charge recombination, which lowers the efficiency; limited number of available catalytic sites, which results in low productivity; and lack of efficient delivery of charges and reactants to the catalytic sites, which causes sluggish reaction kinetics.

O.o!!!! Woah even the news is talking about Dyson spheres now o.o
By Jacopo Prisco, CNN
(CNN) — What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.
“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept.
