The name 'heart' came up when we realized this is much more than just a power unit. The sophisticated network of connections suggests it also has some computing functions. The machine is actually working, on a low energy state, but we were unable to attune to it in any way that would provoke a predictable reaction. Since the real nature of both the power source and the whole thing in general remains unknown, we've postponed further experimentation. Who knows if the thing won't explode with an incalculable force?
