It will be interesting to see just how much power POET's AOCs will save some of these giant companies if/when they are used.

"Google said it used 4,402,836 MWh of electricity in 2014, equivalent to the average yearly consumption of about 366,903 US family homes. A significant proportion of Google’s spending on electricity comes from its data centers, which support its globe-spanning web services and mobile apps.

Saving a few percentage points of electricity usage means major financial gains for Google. Typical electricity prices companies pay in the US range from about $25 to $40 per MWh, according to data from the US Energy Information Administration. (Prices in different regions range from a few dollars to more than $100). Either way, saving 10 percent on data center power consumption, for instance, could translate to hundreds of millions of dollars in savings for Google over multiple years. Google acquired DeepMind in 2014 for 400 million pounds, or more than $600 million at the time, according to The Guardian."

Kind of puts the cost savings on power usage into perspective.
