When it comes to the term “nuclear”, often associated is fearful radiation thus ones may have concern of the safety.
Though being concerned about the problem with sun light, nevertheless as you know, the sun light is vital to most of the life form obviously.

The sun is exploding with its nuclear fusion process and at the same time it is contracting due to the huge gravity of its enormous mass and these two forces opposing against each other are in a equilibrium state so that its shape is kept in sphere form.
Apparently however, very strong radiation that comes from nuclear fusion is emanating from the sun. Nevertheless, thanks to the magnetic shield around the Earth, such a dangerous radiation will not reach on the ground. Human can never built such a stunning, high perfection and big capacity nuclear fusion reactor.
But, we human being are seeking putting it close to our reach the further highly dense energy, that has been recently getting quite a bothering issue.
To warm up a room, to illuminate brightly a night town, to drive far distant at high speed, to transport huge amount in a short time from a foreign country.
Thus, with large scale power plants and/or engines, this demand has been fulfilled. However herein let a point be raised, “Why don’t you purely focus on the sun?”.
The matter is not of solar power on the ground.
It may sufficiently work, by extending application of capability that human being have in its nature, to rely on mostly that divine natural nuclear fusion reactor.
So ideally can it be stated in that manner but contrary it could be difficult in reality.
Even I, always rely on high dense energy. Sometimes to drive to a place where I can go on foot, or sometimes to use air conditioner, or else that daily goods are product of huge energy.
Long time ago, human do not use such a huge amount of energy and there were no such things as internet nor IT stuff. And even production of vaccine was not available and the existence of virus was unknown. Child survival rate was very low.
Now a days, network and IT are working in well advanced level, vaccination gets available in a remarkably short period of time. Whenever necessary, medical service is available. So, being wished is that the direction of energy consumption is to be toward these purposes while human knowledge is kept so that our lifestyle is of minimized in calorie consumption. Anyhow, that will require a well determined spirits because that sort of lifestyle means to nullify or reduce something that have already matured deeply.
If truly and absolutely correct relation between human and the power of nuclear energy of the sun is not like the present, probably our knowledge and wisdom may possibly lack something.
It’s not a talk of philosophy though now being expected is new scientific way that can solve this problem.
