Predicting jumps in power input

Predicting jumps in power input
  Today’s commercially available silicon panels account for around 90% of total solar panel production. However, alternative solar technologies such as thin films (particularly perovskite solar cells) are developing rapidly. Renewables are considered the best energy source for reducing pollution and mitigating climate change.

Safe storage method key to hydrogen-powered vehicles

Safe storage method key to hydrogen-powered vehicles
A major new discovery by scientists at the universities of Oxford, Cambridge and Cardiff in the UK, and the King Abdulaziz City for Science and Technology (KACST) in Saudi Arabia, has shown that hydrocarbon wax rapidly releases large amounts of hydrogen when activated with catalysts and microwaves. This discovery of a potential safe storage method, reported in the Nature journal Scientific Reports, could pave the way for widespread adoption of hydrogen-fuelled cars.

The advent of bacteria-powered microscopic 'windfarms'

The advent of bacteria-powered microscopic 'windfarms'
A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic 'windfarms' - or other human-made micromachines such as smartphone components. The study, published in the journal Science Advances, uses computer simulations to demonstrate that the chaotic swarming effect of dense active matter such as bacteria can be organised to turn cylindrical rotors and provide a steady power source.

Reducing meat consumption could save 5.1 million people by 2050

Reducing meat consumption could save 5.1 million people by 2050
A small team of researchers at Oxford University has published a paper in Proceedings of the National Academy of Sciences detailing their attempts to merge region-specific health models that are based on diet and weight related risk factors with global emission economic modules, to produce impact estimates on health, economics and climate change, if the consumption of meat were to be drastically reduced in the near future.

Material increases the lifetime of solar-powered electrons

Material increases the lifetime of solar-powered electrons
Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated such a material. They combined two oxides on the atomic scale. The interface between the oxide materials, one containing strontium and titanium (SrTiO3) and one containing lanthanum and chromium (LaCrO3), absorbs visible light, producing electrons and holes that might be useful for catalysing reactions, such as producing hydrogen fuel.

Stable perovskite solar cells are the new future

Stable perovskite solar cells are the new future
Progress has been announced in the quest to overcome one of the biggest obstacles to cheap solar power. A tandem solar cell exceeding 25 percent efficiency has been proven possible, but the long-run potential is much higher. Perovskite cells have shaken up solar research. They are potentially very cheap to make, and while their efficiency doesn't yet match the best silicon cells, records have been broken faster than for any previous cell-type, and they show impressive adaptability.
