15 Aug Gunter Pauli’s stories about Solarus technology
Prof. Gunter Pauli is our best ambassador in the world. His mission is to make the world a better place in applying science, technology and common sense based action in creating true sustainable business ecosystems. Serving social, ecological and economical needs. Gunter is a highly appreciated advisor of governments, cities and corporates all over the world. He is an inspiration to many, especially to young scholars and students. And he also is an inspirator for all of us at Solarus.
The Blue Economy
Pauli has written his ideas in The Blue Economy. With the subtitle: 10 Years, 100 Innovations, 100 Million jobs. He has based this book on extensive research he commissioned by ZERI (Zero Emissions Research and Initiatives), which has over 2,000 international scientists and associates. One of the 100 technologies in Gunter’s publication is our hybrid solar collector.
It is Gunters philosophy to start developing a new holistic and systemic way of thinking with kids at the age of 6 to 12. For this reason he has written now 100 fables on all the technologies he has selected for ZERI. In fact even two stories were written about the Solarus technology:
The sun shines on both sides
A geranium is enjoying a bright day in the sun at Table Mountain when a caterpillar crawls over it leave and settles on the bottom for a nap. The cool spot in the shade provides cover while the bright flowers eautify the area.
“If you think you sit safe and cool there, beware because soon the sun will be shining on the bottom as well as on top” remarks the Geranium.
“That is not possible” replies the caterpillar, “if the sun shines on top, then there can only be shadow at the bottom. That is quite obvious”.
“That may seem true but if there is some water that reflects the sun back, it could hit the bottom like these new solar panels are enjoying.”
“Enjoying? How would I ever enjoy loosing my safe and cool little spot to rest?”
“Well you would not be happy, but imagine that all these solar panels that man has been putting on the roofs to make electricity only receive sun on top, never on the bottom”.
“That is because they want to imitate nature? You plants only use the sun on one side don’t you?”
“This has nothing to see with learning from nature, this is more to do with using what you have. They could get double the power.”
“So are you suggesting that these solar panels made from sand should have the sun shining on both sides?”
“Absolutely. If you can make energy on top and on the bottom, why would you only use the top? We have to do more with what we have.”
“Look I want shade, and if this is no more shade then it gets too hot. You may even burn away. And I have heard that if the solar cells get too hot, these do not work so well.”
“What do you do when it gets too hot?”
“I ? – Well I like to take a shower”
“Exactly when it is too hot, you use water to cool down and then what do you have?”
“A nice fresh and cool body!”
“Ah you – what happens to the water”
“It will be dirty with my sweat!”
“Is that all?” wonders the Geranium.
“Oh now I get it. A house can have more energy and hot water that is even clean. That is the way to live in the future.”
And it only has just begun.
Solar power at night
A desert fish is swimming in the sand looking for a cool spot to hide. This salamander like reptile can walk on hot surfaces where even a cricket would burn its feet.
“I am in need of a cool place” screams the cricket.”
“Then you better put up a solar panel!” suggests the desert fish.
“A solar panel – to make electricity?”
“No a solar panel to make a cool space underneath your feet”.
“Ah I get it, we have a solar panel, then we make electricity, then I buy a refrigerator and then I go and sit in there. Sounds fine but that is too expensive for me.”
“You do not need to buy a fridge. You can simply dig a hole and that keeps you cool thanks to the water tubes in the solar panels”.
“Excuse me for being a bit slow, but you can slide into the sand without ever bruising yourself but I cannot see how water pipes in solar panels give me a cool place underground.”
“Well what happens to water in tiny pipes in solar panels during the day?”
“Obviously these get hot. This works like water cooling car engines”.
“Now what happens with hot water?”
“Sorry my friend but in this broiling temperature, I am not in need of any hot water. I need cold water – I want to cool down – and I want it now!”
“You have been around long enough to know the days are hot and the nights are … ?”
“Cold – yes but the problem is I have to survive the day to get to the night”.
“So if the night gets cold, what happens to water in the pipes of these black solar panels?”
“I can very well imagine that gets ice cold!”
“And what happens to cold water?”
“I know – hot water goes up and cold water goes down. Oh now I see. I can even keep cool all day when this water flows around my little hide out.”
“Great – thank to solar panels we can make it cold at night without aircon or refrigerator. That is creative – and cheap.”
“It will take decades for people to figure that one out” laughs the cricket.
And it only has just begun.
