PETD-I

PETD concentrates a smart, precise, high power pulse to the ice/substrateinterface for between .01 - 4 seconds to heat a minimal layer of interfacial ice tojust above the melting point causing the ice to slide off a resulting thin water film.

"An ice surface has a high electric charge. Ice doesn't simply cake onto surfaces,it bonds in three ways: via the hydrogen atoms themselves, via an electrostaticbond caused by the current and via comparatively weak van der Waals forces.

There is no surface coating which can suspend those three forces. That is whythe search for ice-phobic coatings has failed. PETD melts just a few microns ofthe ice interface and gravity does the rest." - Dr. Victor Petrenko

Plane Deicing

The chemicals normally used to deice aircraft - ethylene glycol and

propylene glycol are both deadly substances even in small quantities.Ethylene glycol causes central nervous depression and kidney and liverdamage and propylene glycol is just as toxic. While no studies havebeen done on its effects on humans, each winter large amounts of fishand wildlife are poisoned to death by aircraft deicing chemicals.

Additional pollutants, including fuels and other toxic substances, arealso washed off the planes during deicing procedures.

Compared to the rest of components of aircraft pollution, this is a minorone, though it could have harmful effects on those few who perform thisactivity, and on some unfortunate fish and fowl. This aspect of aircraftpollution has not received much attention so far.- Source

:Uddevalla Bridge: Current Projects

Uddevalla Bridge, Sweden

PETD technology was tested in Sweden in 2006 where a 1712-

meter-long "cable stayed" bridge has major problems with icingand must be closed down for significant periods of time during thewinter months due to dangerous chunks of ice falling at random offthe towers and cables from heights of up to 140 meters.

Each steel cable is covered by a thin polymertube (wrapped in stainless steel foil) to preventrusting. "We apply [an] electric pulse to eitherend of the cable for about one second,"Petrenko says, "and all ice attached to it fallsdown." - Scientific American article

The first tests of PETDdemonstrated instantdeicing action withminimal energyinvestment.
