Even huge, expensive reactors haven't worked.  But now, engineers in the U.S. and Russia say they've fused atoms together in a drink-size glass container.  The claim is not "cold fusion."  The engineers say they've momentarily generated temperatures as hot as the sun within tiny bubbles that have been quickly collapsed using sound waves.  The same claim was made two years ago, but controversy caused the engineers to refine their experiment.  They say re-designed instruments can now clearly detect the tell-tale byproducts that prove fusion.  Details will appear this month in the respected journal Physical Review E,  and former critics are taking a second look.   Stay tuned!  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
