Recouping costs claims are BS
"the company claims that buyers can expect to recoup the cost in energy savings in three to five years."
I'd like to see the math backing up this assertion. Here's some math disproving it:
100KWh (kilowatt hours) is about $10 in the US, so a years worth of electricity would cost $87,600 on average. With a price tag of $700,000 it would take about 8 years to recoup your costs *ONLY IF ONE ASSUMES THAT THE COST OF THE FUEL IS ZERO*.
In Hawaii the price of electricity was 32.28¢ per KWh in 2008, at that rate your bloom box "pays for itself" in about 2.5 years (again *ASSUMING THE COST OF FUEL IS ZERO*).
 While this price varies depending on location,10.04¢ was the US average for combined residential, commercial, and industrial costs for 2008-2009.
