In fact I'm sure there's more than one, but I certainly find it fascinating.
One of the problems today is the rate at which technology advances. The result is that we tend to take astonishing developments on our stride - an amazing technique here, an astonishing device there, we're all a bit laid back about it.
Barely a lifetime ago there were no computers, no jet aircraft, no space exploration, no transplant surgery, or colour TV, or takeaway restaurants, or internet, or mobile phones.......the list goes on and on. Hardly a hundred years have passed (103 actually) since the first powered aircraft flew 120 feet, and now we all travel the world at the drop of a hat, closeted in considerable comfort, 8 miles up, in outside air temperatures of minus fifty degrees or thereabouts.
We have technological overload, and it's not surprising that news of batteries the size of a rice grain doesn't send everyone into paroxysms of amazement.
It is pretty exciting though - these things could work wonders in many ways.
