Original Post: British company Cool Technologies has unveiled a car seat that wraps a child in a protective bubble and calls emergency services. The Carkoon is made of Kevlar, the same material used in body armor. In an accident, it deploys a Kevlar and fireproof Nomex air bag. The air bag covers the entire seat and can withstand impact from flying objects. A transmitter signals emergency services with GPS coordinates and details of the accident. The Carkoon could go on sale as early as next year and will sell for about £499.
