Short Film: Momentum

There are so many people making interesting short SF films.  This one is by Stage 5 TV.  They've got a bunch of SF themed videos on their youtube site, including the Space Pals series, a humourous riff on 2001: a Space Odyssey with adult content; Biohazards, a job interview at the Umbrella Corporation (for Resident Evil fans) and a lot more.  

Here's their synopsis for Momentum, a film by Matt M. Murphy and Jeff J. Daniels:

In a not so distant future where fossil fuels is scarce and the search for the next energy source is at its highest, a lonely inventor struggles to develop the "never-ending battery". When a mysterious woman enters his life, it seems he's not the only one interested in his invention.
