I am a specialist in solar energy (in 12Volt systems)
and eco buildings (round wooden houses, yurts, domes)
and I like to give my skills to younger people,
in order to better the world bit by bit.
I could come to any place in the world,
to make a workshop,
or give practical or theorectical lessions.
My main language is German, my english 85%, my spanish 35%
So I would need some translation help when I have to teach in spanish.
I am married and a father of 2 young daughters.
So if the project goes longer than 2 weeks,
I would prefer to have my family with me.
I am used to live very simply.

I'm offering a professional service with a defined price
