And yes, it's done through private funds and with people and organizations who care.
On September 11th at 6:59am PST, at the same exact time that FDNY Firefighter Stephen Siller was killed when the South Tower fell, the Tunnel to Towers Foundation and the Gary Sinise Foundation turned over the keys to Cpl. Juan Dominguez, a triple-amputee veteran from Afghanistan. This video shows the smart home technology used by the Building for America's Bravest Program.
God bless CPL Dominguez and those who made this possible. And, btw, that's some pretty awesome technology.
