In Hamburg, Germany, the construction of the first residential building in the world whose energy it consumes is produced from the sun and algae has recently been completed. The pleasure of home in your eyes?

One of the most interesting and original developments in the field of renewable energy is a five-story building, the construction of which was recently completed in the city of Hamburg, Germany. The uniqueness of the building is that all its sides facing the sun are covered with flat containers containing algae.

No need for electricity
Water, carbon dioxide and minerals, which the algae love, regularly flow into the tanks, and in return the algae provide bio-fuel that is stored in the tank, from where it flows to the generator located at the heart of the building and produces energy. The same containers are also used as thermal solar collectors, so that the energy produced from the algae and the sun provides all the needs of the building, and it does not need to be connected to the electricity grid or any other man-made external energy source.
The green building, literally, contains 15 apartments, and is the first residential building in the world whose energy it consumes is produced by algae. The planning work and construction of the building lasted about three years, and its cost is about five million euros.

The most effective is to grow marijuana in the walls and in return buy regular fuel for generators. The generators will of course be activated when it is not possible to use unaccumulated solar electricity.
As a matter of fact. There is probably only half of the real story here. As a house for use in a non-insulated settlement, the method is bad, since it is cheaper to connect to the electricity grid and if it is not possible to connect to the electricity grid, use generators and regular fuel. This house can only be suitable for isolated places, where there is no electricity network and no fuel is available.
Why did we build in Hamburg? It is probably a subsidized experiment (not at the expense of the tenants).
Utilize the walls of the building to produce energy for the building's use? genius idea!
How do you do it? The million pound question.
Or rather, the million Deutsche Mark question.
Possible, but the capitalists who hate alternative energy prevent it through their control of the Ministry of Energy.
Or, I have long wondered how the walls of houses in our sunny country can be used to create energy like solar boilers.
Imagine this knowledge leading to a wall or 2 in our buildings that get the most sun? Maybe we can provide most of the electricity ourselves?! In 20-30 years? I'm not in a hurry..
The interesting thing is not the existence of the building,
but the data that can be collected on the functioning of the building after a reasonable period of activity.
What happens when there is no sun? in winter? How much does it cost to maintain the building? What are the steps in maintaining such a building?
How often does glazing require cleaning, and the effect of dirt on the electricity output?
Is it necessary to replace the algae (I don't understand algae much)? Is there a need for a routine examination by a marine biologist in order to examine the health of the aquariums? And again and again very interesting questions.
I am disappointed by such letters. As an experiment, inhale. But the article presents this as a goal in itself, I hope there will be a follow-up article after the function of this building.
And what will happen when they build another building next to it that will hide the sun? Or in other words - what is the distance at which it is forbidden to build another building so that it can still use the sun's energy?
