- Jürgen Kleinwächter, during the technology month in Tamera, presents and explains the very light weigh inflatable membrane mirror, FixFocus, a concentrated solar mirror, developed in partnership, highlighting its great value for sustainability and regeneration of the environment, contrasting its low cost.
"The use of concentrated sunlight allows high temperatures of up to over 2000 °C to be generated for a wide variety of purposes. This enables for example ceramics or building materials to be fired or metals to be processed in a completely clean and emission-free manner.
In order to make this technology accessible to the decentralized village communities, we have developed a new type of solar concentrator, the Fix Focus mirror, which has two outstanding properties:
1- It concentrates the sunlight stationary in a focal point near the earth's surface.
2- Its precise optics is created by “inflating” lightweight membrane cushions and is therefore easy to manufacture locally."
CHALLENGES IN PROCESSING OF MATERIALS WITH
HIGH TEMPERATURES
"Currently in the Global South, the processing of materials at high temperatures as described above, is carried out through the extensive use of wood and charcoal. This intensifies the global greenhouse effect, promotes the development of deserts through deforestation and leads to massive health problems for people through inhalation of the smoke gases. All of these negative effects can be completely avoided by using solar energy."
THE CONCEPT
OF THE FIX FOCUS MIRROR
"Pneumatic shaping of a thin membrane creates a precise eccentric parabolic mirror that can be easily produced locally. The mirror automatically follows the sun and creates a fixed focal point with high energy density. The radiation energy is directed into a cavity and creates a radiant heat chamber."
Fix Focus Mirror demonstration units can be found at the TTT-Center in Portugal.

The thermochemical heat pump is very clever. Thanks for the video.
Thank You, Sir.
✌Cuya! ..., jump. 🙏
great content thanks
can't wait to get those at home!
where can we find more details about everything here?

Great system ...briliant minds .....i've been busting my brains about this things looooong time .....12:45 2 years over ....is it finished? ....what would be the cost of one unit for average home use?

This is great. Are plans available or will they be available?

maby you can use oil pomp heat the oil use the oil pipes true a sand storage
Why not simple use photovoltaic and some LiFePo4 batteries?
panels are 20% efficient best case. Thermal can be near 100% (if you need heat energy for things like HVAC, hot water, cooking) and storage can be much cheaper. 1L of water stores about 1Wh PER degree C that you heat it. Water is cheaper than batteries.
@@dandil Seems You do not know anything about heat pumps. When You mention water, we are in the temperature range of heat pumps.
In some cases, heating and cooling is used at the same time, so the heat pump is far superior to the thermal system.
You simply didn't understand or watched the video. He explained a non-toxic application and fairly accessible to communities. He even mentioned the contrast with PV and lithium based batteries. But in addition, PV end of life are a environmental hazard, no one wants to recycle them being not economically feasible. It's common knowledge by now how it goes with lithium batteries.
@@unagisama5476 We will recycle everything, including 585 billion tons too much CO2 in the atmosphere.
XLnt !
Dieses - zugegebenermaßen schlecht produzierte ;) - Video zeigt deutlich, es gibt Lösungswege. Danke!
"the system must be of course tight to hydrogen, its nothing" WRONG! keeping hydrogen in storage is VERY difficult lol. Getting water from the air is also a tired, unworkable idea. It is WAY more efficient to pipe or truck it long distance. Like orders of magnitude less energy. I love the work overall, especially heat storage and the stirling engines, but this guy needs to brush up on his thermodynamics.
Yeah, wondering about hydrogen embrittlement and maybe some cycle that can perform like a hydrogen embrittlement relief alternating step maybe? Also, wondering about using something like a platinum lining and what the minimum thickness would be required to seal and prevent? Wondering as well what the latest and greatest other materials might be to seal and prevent the hydrogen adverse reactions?
Yeah what the fuck the German science institutes know, right?
