There was one special bettery among the hundreds in our room. My partner and I assesesed the voltage (V) of the battery before lunch. It was 2.68 v. We then checked after lunch and it had increases by point 7 V. Then the real fun started. We never thought we would have a sufficient scientific break-through in five hours of sitting in a comfortable chair. However, we drained the battery by short-circuiting it and five minutes after, it had revived itself! This is true…! We have broken the banks of discovery, Now there is no horizon which innvoation cannot cross. We have finally found a battery which recharges itself!!!!!!!
