Read this article this morning and it will certainly impact the metal construction industry. Take a read for yourself and let us know what you think. We are starting to see science and metal construction come closer together than ever. It’s always had that relationship, but it continues to be more complex. Anyhow read the article and let us know what you think.

http://www.zmescience.com by Tibi Puiu – Solar cell technology has improved dramatically over the past couple of year, yet it will be a long time before multi-junction cells – then kind that can reach efficiency well over 40% – will become affordable to small home owners or even large scale installation. New methods are always explored, however, each with its own angle to harnessing solar energy, benefits and disadvantages included. One of the biggest challenges to improving solar cell efficiency is collecting light frequencies that are outside the visible spectrum, and a new technique developed at Caltech makes use of a most interesting physical effect: plasmon resonance on the surface of metal nanoparticles.
