Technology and Market Opportunity for US Seismic Systems, Inc.

MONTCHANIN, Del., April 26, 2012 /PRNewswire via COMTEX/ -- Acorn Energy, Inc. (nadsaq:ACFN) today announced that the company will hold an Investor Day on May 9, 2012 to showcase the domain changing technology and growing market opportunity for US Seismic Systems, Inc.

USSI's target is the oil and gas seismic market, with an addressable size of approximately $1.5 billion. The company believes that its new Ultra High Sensitivity fiber optic sensors have the potential to increase significantly the number of oil and gas fields being monitored. Today, the company estimates that only 3 percent of the fields are currently monitored.

The USSI sensors, powered only by light, are designed to replace the 50 year old sensor systems currently deployed by potential customers and support the new oil and gas recovery techniques needed to meet the world's increasing demand. The USSI systems are more reliable, more precise, less expensive and inherently safer.

The investor day will commence at the:
