Planning for Avalanches

Technologie Alpine de Sécurité creates gas-powered avalanche control systems. The blog Pruned shows pictures of the system installed at Val Thorens, France.

"From a distance, they look like disembodied talons jutting out from the rockface, ready to prick at imminent disasters. With their array of remote sensors, they are constantly reading the landscape; the mountains are kept under constant surveillance, lest they want to endanger quaint Alpine hamlets and new luxury ski resort developments above Denver or lose skiers to the wintry wilds.

When an avalanche is deemed likely, it detonates a mixture of oxygen and propane gas in its explosion chamber. The resulting hot gas is then directed downwards to the zone at risk."
