Tesla’s Wireless-Power “Dream” Gets Closer to Reality
13 Oct 2025
POWERLIGHT TECHNOLOGIES - Tesla’s dream of wireless power transmission has long captured imaginations. A new article from EDN, “Tesla’s wireless‑power ‘dream’ gets closer to reality — maybe,” offers a compelling update on how that vision is inching toward practical demonstration.
What’s particularly exciting (and validating) for us at PowerLight Technologies is that optical power beaming is now being spotlighted as one of the most promising paths forward. The article highlights:
- Recent DARPA experiments where over 800 W of power was delivered across 8.6 kilometers via laser transmission.
- A design by PowerLight that encloses the beam in a virtual “safety curtain,” interrupting power delivery in microseconds if something crosses the path, ensuring the technology is responsible, safe, and adaptive.
- The broader challenge in scaling up wireless transmission: atmospheric interference, beam focus, alignment, efficiency tradeoffs.

Note: PowerLight Technologies is headquartered in Kent.
