The penguin man? Engineering humans to survive below -30 deg C

+0
−0

my question is as follows: How cold temperatures can withstand a genetically modified person who has the opportunity for a long time (more than a day ) at low temperatures (below -30 ° Celsius ) to acquire a special layer of dense hair, like what we can see in penguins?

The plumage of penguins is dense and dense: some small short feathers cover the body of the bird like a tile, protecting it from getting wet in cold water.

https://pikabu.ru/story/sherstyanoy_pingvin_6554346?cid=135510523 ( Only photographs of the plumage structure of the Emperor Penguin are important. Is it possible to create similar in my people? )

In General, how much cold this genetically modified person can withstand and how much it is possible to preserve the human form ( so that in normal times it does not differ from another ordinary person)
