Archimedes did this 2000 years ago

It has been around since 1976 or so.
from the web page:
"
Operated by Sandia National Laboratories for the 
U.S. Department of Energy (DOE), the National 
Solar Thermal Test Facility (NSTTF) is the only 
test facility of this type in the United States. 
The NSTTF’s primary goal is to provide 
experimental engineering data for the design, 
construction, and operation of unique components 
and systems in proposed solar thermal electrical 
plants planned for large-scale power generation.

In addition, the site was built and instrumented 
to provide test facilities for a variety of solar 
and nonsolar applications. The facility can provide:
    * high heat flux and temperatures for 
materials testing or aerodynamic heating simulation;
    * large fields of optics for astronomical 
observations or satellite calibrations;
    * a solar furnace; and
    * a rotating platform for parabolic trough evaluation. "
I just thought it was interesting how much of the 
plastic and the tree survived a flux of over 300 WCm2.
I also was reminded of a plant in the Ring World
