|Nikola Tesla: 5G network could realise his dream of wireless electricity, a century after experiments failed|
At the height of his career, the pioneering electrical engineer Nikola Tesla became obsessed with an idea. He theorised that electricity could be transmitted wirelessly through the air at long distances – either via a series of strategically positioned towers, or hopping across a system of suspended balloons.
Things didn’t go to plan, and Tesla’s ambitions for a wireless global electricity supply were never realised. But the theory itself wasn’t disproved: it would have simply required an extraordinary amount of power, much of which would have been wasted.
Now, a research paper has suggested that the architects of the 5G network may have unwittingly built what Tesla failed to construct at the turn of the twentieth century: a “wireless power grid” that could be adapted to charge or power small devices embedded in cars, homes, workplaces and factories.
Because 5G relies upon a dense network of masts and a powerful series of antenna, it’s possible that the same infrastructure, with some tweaks, could beam power to small devices. But the transmission will still suffer from the key drawback of Tesla’s towers: high energy wastage, which may be difficult to justify given the urgency of the climate crisis.
