Fresnel lens, recovers in an old flat TV
Good to know, you can get beautiful Fresnel lenses in the 1st generation of flat TVs (with internal projector). Watch this little video http://www.youtube.com/watch?v=sAT6IRBK_uE
For the record the first I had seen was in 1-92 at Fnac Strasbourg, displayed at the price of ... 93 francs! Yep 100 frs of the time, in short in the 000-100 euros currently ...
So what do we piss off today with purchasing power? We really became dirty selfish consumers of shit !!!

Ah yes read too quickly ...
I thought you were talking about portable CD players ... the first ones must have cost 1 francs in the mid-5000s ...
Should I get the neighbor's doc: this is an advertisement for household appliances from the late 90s ... You will cry over the prices!
So on the EM; we really have become too spoiled dirty kids!

The prices are reasonable, failing to be able to recover, remains to be seen the use that can be made of it ..... heating a stirling engine?
