I don’t know if Yann Arthus Bertrand is known abroad. If not, let me introduce him. He is an ecologist or an environmentalist. It is almost the French Al Gore, but as a photographer and not as a politician…

He has made several ecologist events : books about the state of the earth (Earth from above), films also and exhibitions. And he is also interested in mankind and the show 6 billion others is one of them.

This exhibition was first presented in Grand Palais in Paris and, then a smaller city but still the capital of Brittany Rennes and then far away New York… It presents mankind… 5000 interviews in 75 countries and 40 answers to 40 questions.



It is trite to say but sometimes it is very surprising to compare people's responses to issues such as violence, love, belief, happiness ...

Everyone gives his feeling : a man explains that the birth of his son is the Event of his life, another hopes that the trial of Pol Pot will happen sson, for a third one, happiness is easy … Another does not support people repeating again and again. Or when his wife makes bad cooking.… A survivor of a plane crash who loves life ... You can also leave your testimony, in order to reach .... 6 billion others ...

What I did like ?
It is nice to see mankind speaking… The expo in Rennes was presented in a smaller room than Paris – No wonder it is a smaller city ! – So it had to be adapted to this new space. The solution was to change the themes exposed in the 3 yurts every 10 days.
In short, the show is renewed quite often and you can go several times as long you wait 10 days between the visits ...

What I do not like ?
No where you find explanations to understand how they dedided the themes of the 40 questions… Or how they found the people they interviewed… I know everyone can leave its message but I would have liked to know how they began… Is it spontaneous or sorted? And for what? It's a bit embarrassing to see an exhibition and this lack of transparency ... I know it is not a sociologist work but it tries to look like one…

It is also expensive : 10 euros in Paris, 4 in Rennes, I don’t know how much it will be in New York but …I thought the philosophy of Yann Arthus Bertrand was to permit to everyone to see its works…
Specially when you know that lots of sponsors (cities too) give him money to realize his pictures and films, it would be understandable to get a free entrance…

Open every day except Monday and Sunday until the end of August.

Everybody knows the french crêpes ! And what about the crispy dry ones ?

This crepe is extremely fine, crisp to perfection. Without preservatives or additives. Ideal for ice cream and water ice this summer.

The gavotte has changed since 1920, date of the beginning of its fame. It has different tastes : milk and dark chocolate, caramel with salted butter ...



As very often in the kitchen, the food's great discoveries are due to an error of the cook... who forgot an ingredient in the dough or cook it too long ...

The gavottes are part of those great culinary mistakes ... Here it is not a cook but a woman of Quimper, a Madame Cornic, who at the very end of the 19th century cooked too long his pancakes and the gavotte is born...

The crepe industry began at Quimper, (100 crepes an hour) in 1920. Success !! 30 years later 1500 pancakes were produced in 60 minutes. And as the success continues, a factory is created in Dinan.

Today the group Locmaria includes several brands of biscuit in Brittany. The company signed the Pact of the United Nations for sustainable development ... respect for human rights and environment. In short, a product in accordance with our planet ...

Once upon a time, there were forests... and trees... now there are climbing courses for adventurers who like to be acrobats.

From April to November, you can in the afternoon climb trees in a park in Rennes (when it is not school holidays, it is open Wednesday, Saturday and Sunday). Depending of the weather, of course ... Heavy rain and - du vent à décorner les boeufs - (wind that will dehorn cattle, as we say in French !) are usually day-offs!



Children can try with 2 (my girl was 3 ½ years and a friend 5 years ... they did the course for 2-4 years). Very quickly, kids are independent and climb alone. They can't fall as they are secured by a rope and an equipment including harness and carabiners ... They learn easily and do not get dizzy, those young climbers.

Several other outdoor courses are possible: for 5-8 years, one for 9-13 and then for over 14 years. The rates are on their website ...

Forêt adrénaline is a specialist... they're not only professionnals of tree-climbing, they are also designers of park adventure: they have already opened several parks in the area: one in Carnac in the 2000s ... one at Betton, 10 kms from Rennes.



Don't panic if you are "stuck" on your monkey bridge or if you're frightened by the zip line above the lake. Supervisors, professionals, will help you through.



Adrenalin Forest also offers corporate seminars, "unusual acrobatic exercices" (to test what you're able to do, you and your boss!). Or you can also check thanks to those flights between the trunks'crowns the team spirit of your company. ... You can also celebrate original birthday parties ... or whatever you like ...



In short, they are professionnals in recreational entertainment.

The park entrance is near the campsite Gayeulles... You can't miss it :there are lots of things hanging in the woods ...

One more thing ... Forests'lovers don't have to worry, those professionals are tree/true friends: they do everything to avoid damaging them (don't forget trees are their way of earning a living), or to hamper their growth (the trunks you climb on!). They try to limit their impact on nature and environment. That 's what they say!

Or everything you always wanted to know about the wind turbines .

What is a wind turbine?

It was once the wind god Aeolus, who wanted ... No, stop. Wind turbines are the new generation of the old windmills, used to grind grains or to produce oil. Or to extract water, for irrigation. Our modern mills do something different more virtual, they generate electricity.

Who invented them and why?

It is a Dane (end XIX th) who created the ancestor of the wind turbine.
And it was almost forgotten for about a century. Until, until the energy crises : oil in the 70s and now the desire to diversify energy supplies, the fight against climate change and greenhouse gases…
Nowadays the first countries that are using this energy are Germany (22000 MW), Spain, United States and India (6000 MW).

What about France?

France has a very good potential (the second in Europe), and they plan to install 17000 MW of windpower for 2015. The actual capacity is only 2500MW…
The governement insists on saying that France needs to develop the renewable energy sector to reach 20 % of final energy consumption in 2020.

And in Brittany?

The electric production covers only 5% of its needs. The Rance dam is the main producer thanks to tides. The tidal barrage produces the equivalent of one year's consumption of a city like Rennes (around 300 000 inhabitants).
Brittany could be an ideal place for horizontal-axis wind turbines (HAWT) ... it is quite difficult to find places where you don’t have any house at a sufficient perimeter (300 feet minimum).

Why is it so high a HAWT (horizontal-axis wind turbines)?

Because there is more wind up. The blades can be 15 meters long and the tower up to 100 meters.

Can it be installed anywhere?

There are plenty of conditions necessary to install a wind turbine :
a stable ground, a close electricity network (costs of connection to the main electricity network can be too expensive), a location with frequent and regular winds that blows in the same direction (the material does not like changes, nor winds too strong). In France, it can’t be located on a protected area or if homes are too close.
The site has to be accessible : it is not easy to transport the future wind turbines (which can reach 100 meters) and to install the blades or the tower (up to 100 meters) with no crane. !!!

And power ?

There are 4 types of turbines :
The big ones with a power of 350 KW, the middle one (between 36 to 350 KH).
The other two are for individuals, farms or businesses. the small wind turbine has a power ranging from 1 kW to 36 kW and the very small (1 kW) is used on recreational boats.
An example of consumption: a 100-watt bulb burning for 1 hour a day will consume in a year 36 kWh.

For maintenance ?

In new generations of wind turbines, there are elevators ... but when it does not work, it’s better not to forget the tools down, on the ground !

Against ? Why ?

Plenty of reasons:
The irregularity of the wind energy: it is not very reliable. Wind mills can only be associated with other energy supplies ...

Its storage : what happens when too much energy is produced ... We still don’t know how to store its overproduction.

Waves ... can affect TV reception.

And they are dangerous to bat ...

For it ?

Contrary to popular belief, wind turbines projects pay attention to birds : they avoid migration corridors and even studies from the French League for the Protection of Birds show that it is not worse than the city lights and other nuisances ...

Noise : the first generation were noisy and today the wind turbines respect strictly very specific standards about the decibels they emit. And it is one of the criterion that determines its location. The noise of a HAWT at 500 meters away from a house will be 35 decibels, which the equivalent of a whispered conversation.

The electricity produced does not degrade the quality of the air (no release of greenhouse gases or air pollution), does not pollute the water or the soil where it has been erected. A wind turbine lasts about 20 years.

France should accelerate the development of wind energy and produce in 2020 10% of its electrical consumption. It corresponds to the production of several nuclear reactors.

As for health is concerned, various studies do not indicate any health impact.
A green energy ...

And economically

The wind industry is work ... It is estimated that for an installed capacity of 10 000 MW in 2010, over 20 000 jobs were created in France.
Nationally, wind energy contributes to diversification and independence of the country.
For those who want to invest in France, you can rent your land to receive a wind turbine. You’ll get a rent for that.

Domestic wind turbines

A little one in your garden?
It provides electricity for the home but with some conditions:
- Its size (12m). In France, it is ok without building permits, but above, it requires one and the permission from neighbors.
- a garden (we do not recommend fixing it against a house because it vibrates a lot) but you do not fix it at more than 15 m from your house to avoid the loss of electricity.
And finally, they are not very efficient ... for now. But are perfect for farms, businesses who want to enhance their image of lovers of a friendly energy environment or for those who want to diversify their supplies of energy.
