Introducing LaserMotive’s FAQ Series – How does wireless power via laser work?
Written by Scott Milburn on Wednesday, April 4th, 2012
As we mentioned earlier this year, LaserMotive is listening to you, our friends, followers, and the general public and is answering some of the most frequently asked questions about laser power beaming, or, as we also call it, wireless power via lasers. We’re proud to post our answer to our first question: How does wireless power via lasers work?
We sometimes describe our wireless power solution as an “invisible extension cord” because, just like a real extension cord, it supplies power at a distance from your electrical outlet.
In our case, the process works much like solar power, where the sun shines on a photovoltaic receiver (solar cell) that converts the sunlight to electricity. We take electricity from a source such as a wall plug or generator and convert it into light (via laser). That light is transmitted over a long distance to a photovoltaic receiver that converts the light back into electricity, where it can be used to run a motor, charge a battery, or anything else you’d want to run on electricity!
The significant differences between our wireless power solution and solar power are that laser light is much more intense than sunlight, you can deliver the power anywhere that is in line of sight, and power can be delivered 24 hours per day.
