Technology
Imagine a Smart Home in harmony with nature. The best of technological advancement while respecting nature fully. Everything made useful and using common sense without overextending the resident. Even more when it comes to temperature preferences. The air conditioning unit is completely noiseless. You always enjoy the temperature that is most comfortable for you, day and night. All from the energy of the sun. Of course you can open the windows as well. Whatever you prefer most.
Technology can be more.
When technicians of different trades start to think holistically and think outside the box, much more will be possible than has been imaginable.
A power station for all and everything.
The sun gives us more than we need. Heat, growth and energy. More than all power plants in the world combined.
