A carbon-neutral synthesis of kerosene, or jet fuel, has been produced by scientists, made by combining sunlight with water.

5% of human emissions are generated through kerosene use in aviation, which currently has no alternative for long haul jetting.

It consists of 169 sun-tracking reflective panels that redirect and concentrate solar radiation into a solar reactor on top of a tower built at IMDEA Energy Institute in Madrid back in 2017.

A large percentage of a building’s energy usage is consumed by heating and cooling, but a new dynamic shading system designed by researchers at the University of Toronto could help. Inspired by the skin of krill, the system uses cells of blooming pigment that can block light on demand.

Krill are tiny marine organisms that are usually transparent, but have the ability to move pigments around in the cells beneath their skin, allowing them to turn darker to protect themselves from UV damage in bright sunlight. This, the UToronto team reasoned, would be a useful ability for windows and building facades to have.

This Video Explains Lactic Acid Fermentation.
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.

Using Newtonian physics, physicists have found an expression for the value of kinetic energy, specifically KE = ½ m v^2. Einstein came up with a very different expression, specifically KE = (gamma – 1) m c^2. In this video, Fermilab’s Dr. Don Lincoln shows how these two equations are the same at low energy and how you get from one to the other.

The Australian Capital Territory government has firmed its commitment to deliver one of the largest battery storage systems in the Southern Hemisphere to support Canberra’s energy grid and the continued uptake of renewables with funding allocated in the upcoming budget to progress the Big Canberra Battery project.

The results of the study by Wells Fargo Foundation and NREL initiative showed that PV-coated windows can appreciably lower the solar heat gain coefficient.

From pv magazine USA

In the IN² NEXT project, PV-coated windows from NEXT Energy Technologies were tested against traditional commercial windows, tracking performance based on their respective solar heat gain coefficient (SHGC), an industry-standard performance metric for commercial windows. The results show that NEXT Energy’s technology could lower the SHGC from an otherwise equal window to below .20.

Wireless charging roads equipped with energy storage systems are promising electric vehicle solutions by virtue of their strong advantages in time saving and reduced pressure on the existing power infrastructure, according to a paper by Cornell researchers published this month in Applied Energy.

The electric vehicle (EV) industry has experienced remarkable expansion and technical development during the last decade. It is estimated that EVs will comprise 48%, 42% and 27% of light-duty vehicle sales in China, Europe and the United States, respectively, by 2030, according to co-authors H. Oliver Gao, the Howard Simpson Professor of Engineering, and Jie Shi, a former Cornell systems postdoctoral researcher.

Integration of wireless charging roads into the existing electricity market and efficient management of the corresponding energy storage system are crucial for successful implementation of the wireless charging road systems.

A scientific article just published by four Brazilian and two American scientists reports gains in electric and thermal energy obtained when brewer’s spent grain (barley bagasse), an abundant waste produced by the beer industry, is treated with ultrasound before undergoing anaerobic digestion, a microbiological process involving consumption of organic matter and production of methane.

Pre-treatment generated biogas with 56% methane, 27% more than the proportion obtained without use of ultrasound. After purification in methane, the biogas can be used as vehicle fuel with a very low carbon footprint compared to conventional fossil fuels. Moreover, in cogenerators, the methane can be burned off by the brewery to produce electricity and heat. The final waste can be used as biofertilizer instead of mineral fertilizer. The methodology is described in detail in the article, which is published in the Journal of Cleaner Production.

The innovative process was developed at the Laboratory of Bioengineering and Treatment of Water and Waste (Biotar) in the State University of Campinas’s School of Food Engineering (FEA-UNICAMP). The research group lead, T nia Forster-Carneiro, is principal investigator for a project supported by FAPESP.
