Something different altogether

The feeling which comes after inadvertently deleting one's work is difficult to describe. First, I think, comes a wave of disappointment over the time spent and the effort, depending on the quality of what was written. Following, comes a desperate attempt to retrieve the material, even as it is obviously gone. Then there is an assessment of whether to write the entire thing over again or just a synopsis, or perhaps something different altogether.

Did you hear that they are going to start using 'sea-power' to generate electricity in London?

Maybe some day we could generate electricity from all sorts of things.
What if we could generate the electricity in a gym by using 'treadmill-power,' energy taken from the work done by the gym members? I mean, there's got to be a lot of energy generated there, right? I don't know how charging batteries works, what if you could do it just by walking? Self-charge your own iPod? I have no idea how those things could possibly work. But wouldn't the world be a nicer place to live if we didn't have to bear the stress of looming 'environmental concerns' that seem to be getting bigger every day?
