Oman has a warm desert climate and along the coast you will experience great humidity in summer. Temperatures during summer may exceed 50 degrees Celsius, so keeping those miners running.... will be costing them a fortune.
They'll be using bitmain hydro cooling bitcoin miner on the farm. With liquid the system will stay cool at all time, no extra difficulty or charges would arise.
possibly a backup option when the oil runs out.
Not only a back up project, but a way to initiate her citizens into bitcoin technology, which will help the individual economy of their youths in future, thereby increasing the country's economy. They'll be hiring locals to work there, an excellent decision, citizens who work there will practically study bitcoin, how it works etc, in few years the information will circulate amongst other citizens in the country, increasing the use of blockchain technology in Oman. They believe, it's the future and indeed it is.
Contrarily to that, profits from mining in Asia countries is quite recommended due to low electricity costs, but mining difficulty keeps increasing; surged at around 6.17% at block height 804,384 and nobody can predict how difficult it would get in future. The only difference that I can point out why the Oman Government invest so much into bitcoin mining is what I said above, enlightening her citizen on the importance and future benefits of blockchain technology.
