6 Craziest Patents Owned By Google!
2. Floating Wave-powered Server Farm
Watching videos on YouTube for long hours or chatting to your girlfriend till late nights will surely increase your internet bills but do you know how much Google has to pay to offer you these services, building a strong server. Google has to spend million megawatts of electricity in a year. 
Now that’s a serious matter of concern for Google.
It is thus in 2008, Google filed a patent application for a "Water-Based Data Center" to reduce its electricity bills. This would consist of a barge or cargo ship outfitted to harvest energy from tides and convert it to electricity, which then would be used to power computer servers for Google's global information network.
3. Gadgets that projects keyboard onto your hand
Did you notice “Tony Stark” in the “Iron Man” movies was equipped with a voice and gesture-activated computer with an optical head-mounted display that helped him in almost every fight.
Apprehending the idea and technology, Google filed a patent for “Methods and Systems for a Virtual Input Device,” technology in 2013. This technology will enable Google’s Glass to project a virtual keyboard onto the user’s hand turning it into a virtual smartphone-style touchscreen for the user's other hand.
And thus here you become quiet close to be an Iron Man! Wow, that’s a catch.
