The Latest in IT Security

For automakers, CES is often dominated by self-driving and the ever-growing notion of the connected car, but Toyotas taking a more environmental tack with todays announcement: its reiterating the call that it will have a hydrogen fuel cell car for sale to consumers next year that produces nothing more than water vapor from the tailpipe. Toyota has said in recent months that it would have fuel-cell tech in consumers hands around 2015, but this is the first time that its locking next year in stone — and itll be a global launch, including the US. Toyota has been driving this camouflaged fuel cell prototype, based on the Lexus HS250h, around the United States for the past year. The systems, which store hydrogen at extremely high pressures, have struggled with sufficient range, problems in extreme weather, and infrastructure — the cars arent any good without hydrogen refueling stations in place.
