Are we ready for this jelly? Fluorescent jellyfish may help solve our energy crisis

Jellyfish are worse than your tropical beach holiday.
They blocked the entrance pipes of the nuclear power plant, capsized fishing boats by weighing fishing nets, and launched guerrilla warfare against the ecosystem.
But scientists have also figured out how to use the strength of the tent army.
Sustainable solar cells made from jellyfish goo are just a project in the field of bio-solar, which uses biological materials to take advantage of the energy of the sun.
In other words, one day your life may be affected by bacteria, plants, algae or even-
If it\'s compensation for aquatic animals
Destroy the glue-like spots of your last swim.
We need help.
At present, 80% of our electricity is produced using fossil fuels, which is 1-
Climate change emissions accounted for the third.
While traditional solar panels can provide clean renewable energy
The scale expansion of these devices will face resources.
Limit the problem.
For example, a thin-film dye-sensitive solar cell uses ru-
But it\'s a rare (toxic) metal.
The same is true of cadmium and arsenic.
Most commercial solar panels are made of silicon, the second richest element on Earth, but even these traditional solar cells require silver electrodes.
In addition, silicon must be converted from sand with expensive energy
Intensive process.
Barry Bruce: \"Most silicon panels have to run for 8 to 10 years before they can restore the energy they need to make them, \"Professor of biochemistry, cell and molecular biology at the University of Tennessee and pioneer of bio-solar power told Sharon.
\"So there\'s room for improvement.
In addition, the operating efficiency of most commercial solar panels is less than 15-20%.
When the light particles from the sun hit the battery of the panel, the electrons are separated from the atom and a hole is left.
These electrons and holes then pass through the device in the opposite direction until they meet the electrode and generate current.
But most of the time, these electrons don\'t exist all the time.
They fall into the holes left by other migrating electrons, generating only heat.
But when nature
For example, a piece of spinach leaves, a piece of seaweed or bacteria
Solar energy is converted into usable energy through photosynthesis, and its quantum efficiency is 1.
In other words, it does a good job every time, putting people-
Shame the solar panels.
Bio-solar researchers are committed
Efficient processes that provide clean, economical and sustainable energy for hybrid equipment.
Enter the Bruce lab at the University of Tennessee.
Because photosynthesis occurs in the reaction centers (or protein complexes) of plants or bacteria, scientists there are looking for ways to extract these reaction centers efficiently and cheaply, so, they can be used for cheap and easy-to-make solar cells.
In the end, a thick paste rich in green material may be made ---
Like the garlic sauce produced by energy. -
Can be applied to a transparent film --
Like a conductive coating, as part of a solar cell kit for low charge
Power devices for storing vaccines, such as mobile phones, LED lights, and small refrigerators.
When these devices lose output, it is possible to simply clean and re-code with local Manual
Purchasing factory materials.
Meanwhile, MIT researchers are working on a Betty Crocker solar cake mixture made of agricultural waste for outdoor usegrid villages.
\"Now there are 2 billion people who don\'t have electricity,\" Bruce told Sharon . \".
\"For example, if they have light to read at night, they can learn to treat water, learn to use vaccines, practice birth control, and learn to implement better agricultural practices.
We can help overcome the barriers to illiteracy in the world.
This type of research has always been considered a niche area ---
Important work in no more than 20 laboratories worldwide.
But the breakthrough progress made this year is attracting attention.
This spring, researchers at Binghamton University in New York were able to assemble nine blue bacteria for the first time --
Power the solar cell to the solar panel, which generates the maximum wattage of any existing small solar cell
Biological solar cells of scale-5. 59 microwatts.
This is not a lot.
This is partly because when we combine biological and non-biological materials
Biological material, we got what Bruce called the \"leak connection \".
According to Binghamton\'s website: \"Typical traditional solar panels on the roof of the House, consisting of 60 batteriesby-
10 configuration, generating 200 watts of power at a given moment.
The cells in this study, in a similar configuration, will produce about. 00003726 watts.
But as Seokheun \"Sean\" Choi, director of the bioelectronics and Microsystems Laboratory at Binghamton, told Sharon, it was still a step forward. “For the short-
Term objective, this bio-solar technology can be used in conjunction with traditional energy collection techniques and can provide some spare energy even in cloudy environments or at night-
Unlike traditional solar panels, bio-solar cells can generate electricity during dark hours of bacterial breathing.
In the long run, these cells can help self-release, Cui said. Continuous, self-Efficient Power.
\"The biological system has its own advantages.
Assembly and selfrepairing.
In addition, they are very cheap and eco-friendly compared to traditional solar cells, which can be manufactured and amplified.
But there is still a long way to go, \"he said.
\"First, the power density must be significantly increased.
There are many potential solutions in this regard.
Genetic engineering bacteria are one of them.
\"Other researchers have turned to jellyfish for help optimizing solar cells.
Six years ago, Swedish scientist Zackary Chiragwandi put thousands of Victorian tree species into a blender to separate the green fluorescent protein of the creature. -i. e.
Something that makes it shine.
Current is generated when the droplets are placed on the aluminum electrode and exposed to ultraviolet rays.
Although the derived energy is very small, its potential to power nano devices used in the body for diagnostic purposes has caused a stir.
In addition, the technology eliminates the need for expensive and difficult --to-work-
Titanium was found in the Gratzel battery, a solar cell that uses dyes to simulate photosynthesis in plants.
Now scientists can plant their own mixers. free GFP.
This year, Iranian researchers made a solar cell using green fluorescent protein coupled with light.
Protein activated by bacteria
The open circuit voltage reached (690 mV) is \"equivalent\" to the open circuit voltage of traditional dyes\"
Solar cells.
According to Iran\'s MEHR news agency, \"with further optimization of energy conversion, these batteries can replace the older generation of solar cells in the near future.
Chiragwandi told Salon, \"so is it possible that one day your home will run entirely on the strength of jellyfish ? \" He added: \"I can\'t give more details because I\'m still working on it.
Or, as Bruce told Sharon: \"There is a need for two to ten times more money in this area to determine how economically viable BioSolar technology is . \".
At the same time, it is considered to be something of science fiction. It’s not.
