Science Technology  Designing Wireless Sensors To Be Dropped
Into Volcanoes 126  Posted by Soulskill from the appeasing-the-
spectrum-gods dept. Thorfinn.au writes with this quote from El
Reg: "Topflight engineers based in Newcastle have hit upon a
radical plan for warning of volcanic eruptions. They intend to
build a heatproof sensor unit which can be dropped into a
volcano's caldera and wirelessly transmit data to monitoring
stations despite being possibly immersed in molten rock. 'At the
moment we have no way of accurately monitoring the situation
inside a volcano and in fact most data collection actually goes
on post-eruption. With an estimated 500 million people living in
the shadow of a volcano this is clearly not ideal,' explains Dr.
Alton Horsfall of Newcastle Uni's Centre for Extreme Environment
Technology. 'We still have some way to go but using silicon
carbide technology we hope to develop a wireless communication
system that could accurately
