Researchers have got a technique to extract direct food source from Carbon Dioxide - Science Feed

Yah, You got it right!!!
A new startup company in Finland has a unique idea of extracting edible food from carbon dioxide.
The name of the company is Solar Foods Ltd. and this company is quite interesting because of its idea.

This edible food looks, feels and also tastes like wheat flour which is highly rich in protein, carbohydrates, and fats. This company claims that it uses only air, electricity, water, and special microbes (an undisclosed type of soil-derived bacteria) to produce this food.
Solein is the name given to this single-cell protein by Solar Foods Ltd. The company plans to sell its products by 2021.
During the production of Solein, 100 times less water is needed than soy-based plants and 20,000 times less land is required than traditional farming.

Lets comparison it with beef and soy,
For 1kg of beef, 15,000 litres of water is required.
For 1kg of soy. 2,500 litres of water is required.
But,
For 1kg of Solein, 10 litres of water is required!!!
Also,
In terms of land efficiency, Solein is 10 times more efficient than soy production per acre.
It costs about £4.50 per kg. 

So, How do they make it?

First, they extract carbon dioxide from the air and add it to hydrogen bubbles (via electrolysis) released from the water. Then, feed it to an undisclosed type of soil-derived bacteria. This bacteria releases protein which is dried up to make powder. This type of food production is called a carbon-neutral way.
       
CEO of Solar Foods Ltd., Dr. Pasi Vainikka says,' It is a completely new kind of food, a new kind of protein, different to all the food on the market today in how it is produced as it does not need agriculture or aquaculture.'.

 He also said, 'We thought that making food from the air and the renewable electricity -which is becoming cheaper and cheaper - and would make it for the most environmentally friendly food there is. We could therefore disconnect food production from agriculture, which would then enable scaling without agricultural limitations[such as weather and irrigation].'.

 By the way, it may be used as "Space Food". Once NASA planned to use some kind of food like this but that was only on papers. Solar foods are collaborating with the European Space Agency Business Incubation Centre in order to use it as food in future space missions.
As we know Mars atmosphere is mainly carbon dioxide, which may become a great deal for human colonisation on Mars.


So, That's it for now.

How does a NPU, Neural Processing Unit, works? - Science Feed

By
A NPU (Neural Processing Unit), also knows as AI accelerator, is a computing unit specially designed for the running artificial intelligence and machine learning models efficiently and effectively on a single motherboard with other computing units.  There has been significant rise in the use of NPUs in personal devices like smartphones, laptops, PCs etc. to do personalized recommendations and offline AI processing.  NPUs are capable of parallel processing, low precision arithmetic, hardware acceleration.  These have silicon architecture to kind of simulate the human brain working like human where instruction set of AI efficiently ran. NPUs are not for computing traditional problems as it lacks important physical capabilities. Because of these, AI systems are able to learn faster without wasting time and energy. The parallel computation feature give wings to matrix operations ease, activation functions of neural networks, dot product.  NPUs have got dedicated compute ...

What is Dark Energy? - Science Feed

By
There are different forms of energy. But, there has been speculation of an hidden form of energy that has been kind of hiding from us which constitutes a large part of our universe.  The universe has been found to be expanding faster than the speed of light. The traditional form of energy that we have found has been to be not able to provide that much of push. So, there must be something. This type of energy is called Dark Energy. Dark Energy is that form of energy that is not understood by us but it is fundamental in nature and drives the process of the universe. In Theory of General Relativity, there is concept of cosmological constant which says there is a negative of gravitation or empty space that is all over the interstellar space.  The researchers of DES and others have found that the universe is expanding not alone of known form of energy but some mysterious form of it. This is also related to Big Bang. Dark energy is told to be constituent of 68 to 70% of total univer...

How are LIDARs changing field of Robotics - Science Feed

By
In the field of robotics, there is crucial role of sensors out of which the LIDARs (Light Detection and Ranging Sensors) are very important.  LIDAR sensors send the light and detects back the reflected light from any object to estimate how much far away the object is based on the calculations. Laser is used as primary light source as it can bounce back on most surfaces. These are used to make maps of the area where the robot will move around for navigation.  There are different kinds of LIDAR sensors like 1D LIDARs, 2D LIDARs, 3D LIDARs and even 4D LIDARs.  1D LIDARs are most basic type of it because these emit laser in one direction at a time and a point for point cloud is created. A point cloud is a group of large number of points that create map of the area. 1D LIDAR then moves in other direction and make different point after that.  2D LIDARs are the better version of 1D LIDARs as if you are rotating the 1D LIDAR in continuous rotation to project it in a circular...
