This is the kind of thinking that could lead to better battery technology. Wouldn't it be amazing if the energy density of a system like this beat out gasoline?
Only if you ignore some of the operative words in the announcement: "virtually", "Just the right angle (about 35 degrees)".
For this to work as a storage medium it would have to work at an angle much closer to 90 degrees to avoid excessively large equipment and there would have to be a near perfect conversion both on the input side and on the output side (which as far as I know we currently don't have).
