ERA visits Plymouth to demonstrate at GEES

ERA set up at Devon Great Consols

ERA 'Student' set-up at Devon Great Consols mine

On Monday 29th March (2010) we (John and Trevor) visited the Higher Education Academy’s Geography, Earth and Environmental Sciences Subject Centre based at the University of Plymouth. We met with John Maskall and Jason Truscott, and showed them the portable wireless network toolkit we’ve been developing in ERA.

Here is a video clip and some photos from the demo we did at the Devon Great Consols Mine.

Jason by the ore mill

Ground ore was heated in this furnace building

The gasses resulting from the heated ore passed along covered channels into a 'calciner'.

Inside the calciner, purified arsenic condensed onto the interior walls

Workers chipped the cooled and solidified arsenic off the walls for use a a pesticide.

Crystals formed on the walls of the calciner

The 'Student' team view the site and talk to the 'Sherpas'

An additional IP camera provides an overview of the site

Although the site is not the most challenging from a moblility perspective...

... the South West's weather gave the ERA equipment a fair trial
