13. Bio-Inspired Lightning Protection: Nature’s Wisdom in High-Tech Form
Inspired by nature, scientists and engineers are seeking for novel lightning protection systems. One amazing example is the creation of lightning protection devices motivated by the survival capacity of some trees under frequent lightning hits. These bio-inspired solutions safely channel electrical current by use of a network of conductive routes within building materials, emulating the internal structure of lightning-resistant trees Researching how some animals anticipate and escape incoming storms results in still another nature-inspired invention. Like these animals, ultra-sensitive electric field sensors have evolved to detect the minute variations in atmospheric electricity that precede lightning. In order to produce surfaces less prone to become conductive during rainstorms, so lowering lightning risk, some researchers are even looking at how to recreate the water-repelling qualities of lotus leaves. Using millions of years of evolutionary knowledge, these bio-inspired technologies present creative and usually more sustainable methods of lightning protection.
14. Space-Based Lightning Deflection: The Ultimate High Ground
Some scientists are focussing on space-based alternatives as we consider the direction lightning protection will take. The idea, currently in the theoretical stage, is to affect the behaviour of lightning from orbit by means of satellites fitted with strong electromagnetic field generators. These satellites would operate by producing localised changes in the ionosphere of the Earth, therefore guiding lightning away from sensitive regions. One benefit of a space-based system is its capacity to guard large areas devoid of ground-based infrastructure. The possible advantages are great even if the technical difficulties—power needs and exact targeting among other things—are major. Such a device might safeguard whole towns or areas, therefore saving countless lives and perhaps sparing billions in damage. Concepts like space-based lightning deflection approach reality as space technology develops and becomes more accessible, providing a glimpse into a future whereby we can manage one of nature’s most strong forces from the ultimate high ground.
