Since 4NEW's project tends to install a power plant, I'd say they are more in need of engineers, wouldnt you agree?
Definitely this project will open doors for many engineers and other type of employment as well. No doubt about it. Also in many countries where are planning to have such plants. This project will create huge economic impact in the end for that country.
Depends how they are building the plant, their are companies that 4NEW can handle to purchase the main parts of the plant from outright, but i'd imagine yes they will have to have a decent employment of various engineers, and legal experts etc to make sure that the plan and contracts etc are in place to make sure these somewhat large facilities can operate for the next 30+ years.
That is very true, compared to most Crypto/Blockchain projects this one will require a lot of hard work and dedication from the team, and also a lot of patience from investors.
4NEW could take years to build the energy combustion plants, and they need to ensure they raise enough funds and keep getting new investments and securing new deals.
