Described as the world’s most environmentally friendly protein, Solein is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes(微生物) are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’s a natural fermentation(发酵) process similar to beer brewing. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour.
“It is a completely new kind of food, a new kind of protein, different to all the food on the market todav in how it is produced as it does not need agriculture.” Dr Pasi Vinikka, the chief executive of Solar Foods told The Guardian. The process used to produce Solein — converting hydrogen and carbon dioxide to calories — is amazing, as the wonder food can be produced anywhere in the world. It’s also 10 times more energy-efficient per hectare than photosynthesis (光合作用), and 10 to 100 times more environment and climate-friendly in water use than animal or plant based food production.
“Solein also contains all the essential amino acids(氨基酸), but because it is produced using carbon dioxide and electricity, it does not require large amounts of land to produce,” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.”
While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for sustenance. The Helsinki-based company plans to open its first Solein factory at the end of 2021 and scale up production to two billion meals per year by 2022.

Sixteen brave runners recently gathered in the Russian village of Oymyakon, also known as the world’s pole of cold, to compete in the coldest official race in history.
Oymyakon is the coldest permanently inhabited place on Earth, with temperatures constantly dropping to under -50 degrees Celsius in winter time. This place is so cold that a person’s unprotected face can suffer frostbite(冻伤) in a matter of second. Oymyakon can barely be called livable, let alone suitable for a marathon, and yet at the beginning of this year, 16 runners gathered here to take part in a series of extreme races.
On January 5, the brave runners — aged 21 to 71 and very well-trained — competed in bone-chilling marathons for 5, 10, 20, 30 and 42 kilometers across the frozen taiga(泰加森林) of central Yakutia. At the start of the run, the air temperature was an almost unbearable -52 degrees Celsius, and by the time the first and only runner reached the 39km mark, it had increased to -48 degrees Celsius.
“We could see entire amazement in the eyes of tourists who traveled here from Australia, Taiwan, Japan and India to watch the world’s coldest race,” runner Sargylana Neustroyeva told The Siberian Times. “This was our first try at organizing the extremely cold marathon. Next year we are definitely doing another race, and all athletes from around the world are welcome!”
“We wanted to make running in -450C and colder more popular, and to show that athletes can adapt to extremely low temperatures” champion runner Yegor Abramov added.
The world’s coldest race was organized by Alexander Krylov, head of Turuu Tour agency. He plans to do it again next year, hopefully with more brave runners able to endure the extreme winter temperatures of Oymyakon.
