The 12 storeys are constructed of wooden building elements with straw insulation. It is a climate-positive building that stores the carbon dioxide the trees and the straw bound as they grew - perhaps also the world's most climate-positive building.
There are solar cells on the roof, balconies and facades and the building is a PlusEnergy building - it produces more energy than the tenants use. No district heating is needed, the building is heated with heat recovery from the ventilation air plus a heat pump.
The building consists of 52 apartments for rent (34-91 sqm) owned by ETC Bygg. On the ground floor are premesis for shops/offices and under ground are rooms for bicycles and a shared laundry.
The financing is unique since the base is crowdfunding: more than 3000 people have chosen to save and invest in the ETC building and solar companies (with returns), the rest of the project is financed through bank loans.
Built: 2026. Architects: Hans Eek and Kaminsky Arkitektur.

On Saturday we went to San Francisco to watch the history Solar Impulse solar aircraft fly over the Golden Gate Bridge. We had a nice picnic a Crissy Field. I took this shot of Alcatraz with a tele-zoom lens.
I processed a balanced and a paintery HDR photo from a RAW exposure, selectively merged them, and carefully pulled the curves to make the scene pop.

With Solar Cells on the Roof...
In Augsburg-Inningen
Inningen was an agriculture-based community until the 2nd World War. After the war, the village developed into a preferred residential area near the city of Augsburg, which eventually annexed it in 1972.

The Past on the Edge of the Future - A modest, mid-century, country home decays on the edge of a solar farm and a soybean field in Hertford, NC, USA.
With solar cells on your roof you are not dependent on any other country!
Export of locally produced electricity that you don't need yourself during sunny days and purchase of electricity from the grid at other times.

In front the floating eggs with solarpanels, part of the artwork SOH19 (Alex Vermeulen / Van der Waals).
The startrails are the result of 96 shots, each 15 second exposure time (total: 24min) @ ISO1000, f/5,6
The overal image looks too chaotic due to lack of composition... But even in the center of a (big) city, startrails are possible :-)
The black squares are parts in a photovoltaic system (solar cells) that produces electricity. They are spaced out more on the end of the balcony so you can look out there.

The tall building called "Fyrtornet" ("The Lighthouse"), is Sweden's tallest wooden office building. The glass facade to the left is partly windows and partly solar cells (the small black squares).
The block "Embassy of Sharing" is situated next to the railway station in Hyllie, a part of Malmö city. The block consists of seven buildings with different content, some of them are under construction. In the block there will be, among other things, nearly 300 homes, offices, bazaars, startup environments, a library, a bicycle café and small industries.
"Embassy of Sharing" was the winning proposal in an architectural competition. It is designed by Wingårdhs Arkitekter and built by Granitor.

Solar cells for space are typically grown on slices of germanium metal. An ESA General Support Technology Programme (GSTP) project looked into being able to remove and recycle this rare, expensive metal, resulting in much thinner and cheaper solar cells for missions.
The activity tested a method where the surface of the Germanium substrate is treated so that a cavity is introduced just below it. Once a solar cell is grown on the Ge surface, this 0.001 mm thick gap, or cavity, allows everything above it to be removed, leaving just a very thin layer of germanium still attached to the cell – around 10 micrometres thick instead of the previous 150.
This huge saving of weight and volume of a rare material will result in major cost savings, especially when multiplied across the roughly 10 000 solar cells needed for each satellite mission.
For more than a quarter of a century ESA’s optional GSTP has been preparing promising technologies for space and the open market. Read our GSTP Annual Report for 2019 to learn more about programme activities.

A macro shot of small solar cells on my pocket calculator. I guess that the dust gives a feeling for the size of the visible part of the solar cells.
Captured with my iPhone 8 and the "Black Eye" macro lens.
Thank you for viewing, commenting and / or adding this photo to your favorites. It's very much appreciated.
The towers in the background are the Palo Verde Generating Station, largest power plant in the United States by net generation. In the foreground is a solar farm, another producer of electricity with no CO2 emoission
Here is my capstone team posing in what is supposed to be a propaganda like pose in front of their project. They had the assignment to build a tracking solar system on top of a trailer for the BYU archeology department. I had wanted this picture to be with them facing the rising sun but the weather did not cooperate and they are only facing rising clouds where the sun should be.

These four solar cell lanterns are hanging in my greenhouse. I haven't seen if they work yet because I haven't been on my allotment after dark so far.
You can see them in the background in this picture. (The previous owner used the green house as her kitchen so there isn't many plants in it. I do have two tomato plants and one chili, though)
A solar cell is being turned into a light source by running electric current through it. Such ‘luminescence’ testing is performed routinely in ESA’s Solar Generator Laboratory, employed to detect cell defects – such as the cracks highlighted here.
By happy accident the solar (or ‘photovoltaic’) cell was invented in 1954, just before the start of the Space Age, allowing satellites to run off the abundant sunshine found in Earth orbit and beyond.
Made from the same kind of semiconductor materials as computer circuits, solar cells are designed so that incoming sunlight generates an electric current. But the process can be reversed for test purposes: apply an electric charge and a solar cell will glow.
Solar cells, carefully assembled together into arrays, are an essential part of space missions, together with specially-designed batteries for times when a satellite needs more power, passes into darkness or faces a power emergency – plus the power conditioning and distribution electronics keeping all parts of a mission supplied with the power they require.
“Space power technologies are second only to launchers in ensuring European competitiveness and non-dependence,” comments Véronique Ferlet-Cavrois, Head of ESA’s Power Systems, EMC & Space Environment Division.
“Without the research and development ESA performs with European industry to ensure the continued availability of high-performance space power systems and components we would be left utterly reliant on foreign suppliers, or missions wouldn’t fly at all. We will be taking a look back at the important work done during the last three decades during this month’s European Space Power Conference.”
The 12th European Space Power Conference (ESPC) is taking take place in Juan-les-Pins, Côte d'Azur, France, from 30 September to 4 October, with almost 400 participants. Véronique is chairing the event.
“It will begin 30 years to the week from the very first conference in the series,” adds ESA power conditioning engineer Mariel Triggianese, ESPC’s technical coordinator.
“So we’ll be commemorating our past but also looking forward. Our theme is ‘Space Power, Achievements and Challenges’. The chief technology officers from Airbus, Thales, Ariane Group and OHB will be joined by ESA’s Director of Technology Engineering and Quality, Franco Ongaro, to discuss the space power needs of their markets into the future.”

The frame and the walls are made of wood - a climate-positive building that stores carbon dioxide. It's a super insulated passive house. On the roof there are solar cells. 41 apartments in two buildings in a tenant-owners' society called "Brf Notuddsparken". On the ground floor there is a room for parking and washing of bicycles. The tenants have two electric transport bikes and two electric cars they share. Those two cars have parking places next to the two buildings - other cars have to use the multistory car park at the entrance to the neighborhood. The buildings will be environmentally classified.
Built: 2021. Builder: Bright Living AB, Alingsås. Architects: OkiDoki.
