Japanese farmers have long believed that lightning strikes are great for mushroom farming. They said it made the mushrooms multiply. The world scoffed dismissively and went back to what they were doing.
And yet, a recent study shows that this is actually correct. A very short burst of extremely high voltage electricity improved yields by 80%.
This is of interest to mushroom farmers, who can inexpensively boost yields (since the burst need not be high amperage), and mushroom eaters, who can expect cheaper and more abundant mushrooms in the future. More mushrooms on my pizza, please.
