The future is sodium batteries instead of lithium batteries?

Several batteries have already been designed, however, for the first time, one of these batteries has been conceived that is capable of storing the same energy as in a lithium battery but at a lower cost. The person responsible for the finding is chemical engineer Zhenan Bao and his Stanford collaborators, materials scientists Yi Cui and William Chueh.
This innovative thermal battery would also be able to produce electricity overnight
This innovative thermal battery would also be able to produce electricity overnight
Storage has long been an obstacle to renewable energy, but this innovative thermal battery that is being developed is also capable of producing electricity overnight. This thermal battery is part of the concentrated solar energy system (CSP) developed by United Sun Systems, which requires a battery to store and release energy to allow the generation of solar energy without interruption.
Americans used more energy in 2018 than in any other year
Americans used more energy in 2018 than in any other year
A BTU, or British thermal unit, is a unit of energy measurement; 3,400 BTU is equivalent to approximately 1 kilowatt-hour. According to the most recent energy flow charts published by the Lawrence Livermore National Laboratory (LLNL), the United States had a total energy consumption of 101.
This method that converts sunlight into fuel is more efficient than photosynthesis
This method that converts sunlight into fuel is more efficient than photosynthesis
This new method managed to absorb more sunlight than natural photosynthesis, which could revolutionize the way we can convert sunlight into fuel. The method to 'divide' water into hydrogen and oxygen by altering photosynthetic machinery in plants has been developed by researchers at St John's College in Cambridge and published the results in Nature Energy.
Solar cells that combine silicon with perovskite have achieved a record efficiency of 25.2%
Solar cells that combine silicon with perovskite have achieved a record efficiency of 25.2%
If the energy produced by the Sun in a single second could be stored, the current energy consumption of the United States could be satisfied over the next nine million years. That is why it is very important to reach new efficiency records in solar cells. A new combination of silicon with a relatively rare mineral in the earth's crust, perovskite, has achieved an efficiency never before achieved: 25.2%.
Transparent cells turn windows into solar panels
Transparent cells turn windows into solar panels
This thin, plastic-like material can be used in buildings, car windows, cell phones or other devices with a clear surface. It is actually a transparent luminescent solar concentrator that when placed in a window creates solar energy without interrupting the view developed by engineering researchers at the University of Michigan State that can turn a simple window into a solar panel.
Solar cell developers seek inspiration from black butterflies
Solar cell developers seek inspiration from black butterflies
A technique that improves the ability of photovoltaic cells to absorb sunlight has been developed by researchers at the California Institute of Technology (Caltech) and the Karlsruh Institute of Technology (KIT) in Germany. His source of inspiration has been the black butterflies. Black butterflies The wings of the black butterfly (Pachliopta aristolochiae), which inhabit South and Southeast Asia, have been the inspiration to improve the improvement of photovoltaic cells, as the wings of these lepidopterans are covered by micro and nanostructured scales that They harvest sunlight in a wide range of angles and wavelengths.

The production of solar cells with new materials receives a boost
The production of solar cells with new materials receives a boost
Two million euros to produce solar cells with materials such as colloidal quantum dots and halide perovskites have been invested by the Jaume I University of Castellón (UJI) has obtained the first Grant Consolidator of the European Research Council (ERC). The Professor of Applied Physics Iván Mora Seró, also a researcher at the University Institute of Advanced Materials (INAM), has won the European grant to develop this project, as you can see in the following video.
The most powerful laser in the world
The most powerful laser in the world
The confinement ray of the United States Ignition Facility (NIF), a fusion research laboratory, is considered the most powerful laser in the world. It is an ultraviolet laser with an output power of 500 terawatts. The machinery and electronic components that activate the NIF laser require a larger space than a football stadium.
How much wood would you need to light your house?
How much wood would you need to light your house?
Today we press a simple key and the light turns on as if by magic, illuminating all the recesses of our room, or even the entire house. However, we are not very aware of the energy we are spending. Or rather: we are unaware of the efficiency leaps that humanity has taken to allow us to illuminate our house by spending just a few euros a month (well, in reality they are increasingly more euros, at least in Spain, but that is another matter ).
Improving the efficiency of solar panels in high altitude balloons
Improving the efficiency of solar panels in high altitude balloons
Although Ikea rules out selling solar panels in Spain due to legal lack of control (surely the sun tax has something to do with it), and that in the city of Woodland (North Carolina) a proposal for a solar garden has been rejected after Some citizens will be worried because, according to them, solar panels could "absorb all the sun", the field of solar energy is increasingly leading major advances.
What is the oldest nuclear power plant?
What is the oldest nuclear power plant?
Iceland is a paradise for renewable energy energies: 100% is the proportion of electrical energy in the country from such sources (75% hydraulic and 25% geothermal). The first house powered by hydroelectric power is over a hundred years old and aspired to be a "palace of a modern wizard" (where the first light bulb also shone).
When electric cars were more common than gasoline cars
When electric cars were more common than gasoline cars
The use of electricity to boost our car or our bicycle, although it is becoming widespread, is still something unusual, almost exotic. However, at the dawn of the twentieth century, electric vehicles were very common. At that time, steam, gasoline and electricity competed for automotive supremacy and did it almost at the same level, because electric cars were much simpler and more reliable, as well as silent and less polluting.
With this portable wind turbine you will have power anywhere
With this portable wind turbine you will have power anywhere
Given the energy consumed by our gadgets, every time in greater numbers, we all go on excursions equipped with a powerbank, or a solar panel, and even a dynamo. The latter could be a portable wind turbine, like the one you can see in operation in the video that heads this entry, and that is being financed through a Kickstarter campaign.
An organic device to reduce water to hydrogen from sunlight
An organic device to reduce water to hydrogen from sunlight
A novel organic device that allows reducing water to hydrogen from sunlight only has been developed by researchers from the group of Photovoltaic and Optoelectronic Devices of the Jaume I University. The work has been published in The Journal of Phisical Chemistry and framed in the European project PHOCS (Photogenerated Hydrogen by Organic Catalytic Systemscto).
New battery that will charge in two minutes and will last 20 years
New battery that will charge in two minutes and will last 20 years
Batteries will recover 70% of their charge in two minutes, and will have 10,000 recharge cycles, that is, they will last up to twenty years of conventional use. This is how researchers from the Nanyang Technological University in Singapore promise to be the batteries soon. Those batteries that last a sigh in our smartphone or in our electric cars, for example.
Rice husks to generate electricity in the third world
Rice husks to generate electricity in the third world
The lack of electricity is a problem that affects almost a quarter of the world's population and that slows the socioeconomic development, education and health of people who suffer from it. Initiatives such as that of the Husk Power Systems company that produces electricity from rice husks in Binhar, one of the poorest areas in India.
