Nano-Spike catalysis; Discovery of the Oak Ridge National Laboratory made a little ... by chance! The process makes it possible to obtain ethanol from CO2, electricity and water in the presence of a specific nano-catalyst called Nano-Spike. The reported return on electricity is 60 to 70%, which is acceptable provided renewable electricity is used (the process [...]
While France continues (almost) everything to rely on nuclear electricity ... countries are now, and regularly, beating records of production in renewable electricity! This month it is the turn of Portugal to realize a real tour de force of the renewable! A few days after Germany produced so much renewable electricity that producers [...]

An electric car emits CO2 and not a little! This is the confession, very honest, of a Mitsubishi official in front of France2 last week about the MiEV, electric car last born of the brand. The Mitsubishi MiEV is an 100% electric car that would emit, indirectly, taking into account only the manufacture of [...]
Geothermal heat pumps, energy savings and emissions CO2
To ourt, geothermal energy is all too often presented as a renewable and "green" energy.
This article concerns the surface geothermal energy, called heat pumps, not deep geothermal or deep heating networks catchments themselves are completely renewable.
So if the energy [...]
