Ryobi Airgrip Laser Level Review

Visit: and 7, a class of 2nd Wind

Under the sun this time!

In partnership with Pierre Baffalie Maisons de France and Sandra Farmer Pradier Service Inventory of Heritage Country Midi Quercy.
A very pleasant afternoon with a class of 2nd High School Capou. About twenty people, curious and reactive.
Thanks to them and to Jean-Pierre Cassagne, their teacher at the origin of this output.

The purpose was to talk about heritage buildings, mud brick and sustainable development.
I think it's going to talk about "dry toilet" tonight at the table!

They were treated to a volley of questions and they did not even leak!

There is an interesting link between heritage and to sustainable development, to bring the why, because looking at the sustainable backward positions the sustainable into the future.

My notes for bulk storage and sharing:

The goal is to talk about sustainable development, eco-home.

I'm going back to the roots to speak of. At the end we speak rather comfortable house, logic, economic, safe, supportive, ecosystem ...

First, the result and the difference from the past 50 years: less expensive to build, 4 x less energy and €.

I'll start with questions. No questions to get an answer, this is not a Interro. To solve a problem, really, completely, one must go back to the big questions, as defined. So to talk about how we can build a house, let us return to meaning.

You just see so-called heritage: things made by others before us, they sent us. Things preserved and enhanced by others before us, they sent us.
* What we have done, what we have preserved what we improve, what do we communicate? I talk about things that will still be useful in 100 years, things that we still find beautiful in 100 years?
* Who has pictures block housing? Who comes to tourism in a subdivision? Who comes to appreciate the beauty of a highway into the sunset? Who feels a great sense of happiness when leaving a mall? Who wants to have his window overlooking the parking Leclerc? Who comes walking in family around a landfill? Who bathes his baby in the Tarn the Aveyron? Who drinks water from streams? Crunches on an apple tree after the treatment plant ...

In our basic needs, there "to be protected "Have a cave, a cabin, a house over your head. If I build this shelter, what is most important?

Knowing that today, we go in, + ¾ of our day.

* Is it comfortable? (Warm in winter, cool in summer, no rain, no wind, no humidity)
* Is it continues to be comfortable if a power outage for 1 week? Is it me, living in this house, I master this comfort ? Or is it that this comfort is dependent on a distant energy source? Or does it depend entirely comfortable with a machine (which breaks) or another person (who has other things to do)?
* Is it effective? Is not effective when using a tree to crush a fly. That is to say what means for what result?
* Where does it come? How it was made? Does everyone on Earth could do the same thing? (Or else there would not be enough for this or that everybody) Is if we all like that, our children can also do it like that? And their children?
* Is it not break my health or someone else?
* Does the person who made it were happy to do so? Is she proud?
* Is it beautiful? Is it beautiful in the landscape? And in 100 years?
* Is it going to take long? (Or he will do it again?)
* What it will become, if it is demolished? (Reuse, pollute?)

long time (the first humans (genus Homo ') = 4 million years , mastery of fire = 400 000 years, writing 3,300 years), that almost anything done by the men with the means at each time.
When I'm saying is what they did, I'm not saying they reflected on all that, I say that when you look at the result, we see this: for the time, relative to their needs, we see the top of the comfort and efficiency, real cheap, techniques and materials used by everyone, we see things that take as long as possible AND who have be reused again and for several tens of generations.


• And since we expected to find a source of easy and inexhaustible energy (100 years), we stopped doing that way. We started to smash flies with a tree trunk.
• With enormous resources, we arrived at a result not terrible
boxes were made: very comfortable that we are expensive, full of pollutants for us and our environment, that does not last.
machines were put in to compensate and recover a little more comfort (heating, air conditioning), but the machines are often détraquent and use energy, so the sub.
And we put a whole bunch of complicated systems to move around a lot of electricity, a lot of energy, lots of water, to clean a lot of dirty water ...


After that, explanations and concrete examples, with the educational triptych colander (insulation) + shock (inertia) + Gore-tex (perspiration), which helps explain the relevance of eco-materials without simply "well, it's natural."
