To ensure the future of clean drinking water, we save thousands of liters of rain water below the hotel during rain falls. This also prevents the city center from getting flooded. The energy poles are beneficial as they suck in surface water into the deep via gravity and thereby warm these. That way we can make 50 KW if heat with only 10KW of electricity. There is no bacteria residue of the shower and bathing water as the water is only boiled when needed.
This way we can not only invite our neighbours for a nice tea, but also produce environmentally friendly energy.
