The Solbot, made by startup QBotix, stops at each array and extends a cylindrical arm to adjust the angle of the photovoltaic panels so they capture the most amount of sunas it moves across the sky and through the seasons.
That's because asthe Earth moves around theSun, it is moving into a stationary field of dark matter - and for half the year it will be moving against the tide of dark matter - just like driving into the rain.
