So, heat pumps are more than 100% efficient, in that they move more heat than the energy needed to run them. Therefore, the neighbour should also install this system, creating a closed system that keeps both houses warm at better than 100% efficiency. I think this might solve all our energy needs, and global warming in one go. Tsk, to think the so called scientists have been trying to get fusion working when this solution is already practical.
University is about a lot more than the piece of paper you get at the end. If it’s of any real quality, and you are actually engaged with it, you’ll be learning from experts in your chosen field, amongst engaged and eager peers, whilst also being exposed to different viewpoints on everything from what to have for lunch through the latest innovations in your field, and adjacent ones, to the geopolitical state of the world. The people you meet, and the connections you form can, and often do, form the bedrock of your working life from then on.
All of that does make the assumption that you actively engage with university life and those around you. Make friends in different subjects, seek out your professors during office hours and talk to them about their interests, join clubs, do stupid, but ultimately harmless things.
It also assumes you are attending a ‘good’ university, rather than a profit driven degree mill, and those might be harder to find in some places than others.
