Hydrogen From Tap Water

Spanish scientist José Antonio G. I. developed a prototype system to extract hydrogen from tap water without electrolysis. Pressurized air injected into a tank of water, ferrosilicon, and sodium hydroxide causes a chemical reaction to extract the hydrogen through two additional tanks that can produce 30 litres of hydrogen per minute. Allowing hydrogen to be generated at the point of consumption removes the need for hydrogen transportation.

Sand Battery

#322

Researchers in Finland have commercialised sand battery technology that can store heat energy from excess generation. The excess electricity is used to heat air, and energy is then transferred from the air to the sand using a heat exchanger. The sand battery has been deployed in the town of Kankaanpää in western Finland and is used to power the central heating system for the district.

Freeze Dried Cell Clones

#322

Researchers at the University of Yamanashi have demonstrated the ability to clone a mouse from a freeze-dried skin cell. The process could replace the need to store cell samples for cloning in expensive and sometimes unstable liquid nitrogen.

Artificial Photosynthesis

#322

Researchers in the University of California have developed a method of artificial synthesis that is 400% more efficient at growing plant mass, in the dark. Using a two-step electrocatalytic process, carbon dioxide, electricity and water are used to created acetate. Plants can then feed on the carbon in the acetate to grow without the need of sunlight.

Urine Fertiliser

#320

Farmers and researchers in Niger have conducted trials of urine fertiliser from 2014 to 2016 and achieved a 30% increase in pearl millet yield compared to standard fertiliser. Urine fertiliser is also a much more environmentally sustainable alternative to regular fertiliser.

Infection Resilient Buildings

#319

The Royal Academy of Engineering published a report on building health into construction to make infection resilient buildings. The report shows that in the long run, it is cheaper to build better ventilation and lighting into buildings due to increased health and productivity of its users.

Co2 Battery

#318

Italian company Energy Dome have launched a large scale Co2 battery that can use captured carbon dioxide as a closed system battery. Electrical energy converts Co2 stored in a dome into compressed liquid, while storing the heat generated by the conversion. When the energy needs to be withdrawn, the stored heat is used to heat the compressed Co2 which turns a turbine to generate electricity and refill the Co2 dome.

Underwater Greenhouse

#316

Nemo's Garden is an underwater greenhouse off the coast of Noli in Italy. The greenhouse consists of biodomes used to grow salad greens, beans and strawberries that are richer in nutritional content than more traditionally grown produce.
