The Future of Solar Power: Ordering Sunlight Online

KAZI ABUL MONSUR#

You place an online order, and suddenly—a ray of sunlight arrives at your doorstep.Soon, you’ll be able to buy sunlight to escape the cold. This isn’t a story; it’s reality. Over 30,000 pre-orders for sunlight have already been placed. It remains to be seen how this concept of “buying sunlight” might stir excitement across the globe.
Reflect Orbital, a California-based startup led by Ben Nowak, is exploring new possibilities for solar energy with its ambitious project, Sunlight on Demand. The initiative plans to use 57 satellites equipped with Mylar mirrors (a type of reflector) to redirect sunlight to specific locations on Earth. This innovative approach aims to enable solar power plants to continue generating electricity for up to 30 minutes after sunset.

In an initial test, sunlight was successfully reflected onto a solar panel 800 feet away using a gas balloon. This reflected sunlight generated approximately 500 watts of energy per square meter. The project holds promise not only for increasing solar energy production commercially but also for fulfilling lighting demands in dark areas.

While the project faces challenges such as weather-related disruptions and concerns about light pollution, it has the potential to revolutionize solar energy usage. The first satellite is scheduled for launch in 2025, and the company has already received over 30,000 service requests.

The system involves deploying 57 small satellites in low Earth orbit (LEO). Each satellite will feature a 33-square-foot reflector made of Mylar, a highly reflective polyester film. Users can request sunlight by providing GPS coordinates through an online interface. The satellite system will then direct reflected sunlight to the specified location. This can extend solar energy production for an additional 30 minutes after sunset or provide targeted lighting during nighttime peaks in electricity demand.

In a prototype experiment, an 8×8-foot Mylar mirror mounted on a gas balloon reflected sunlight onto a solar panel, generating 500 watts of power per square meter. Although this is about half the intensity of direct sunlight, the results are encouraging for future applications.

Challenges like cloudy weather or storms may affect the reflection process. Astronomers have expressed concerns about light pollution, but the design of the mirrors has been optimized to minimize such effects. Though the cost of satellite deployment remains high, it is expected to decrease over time.

If successful, Ben Nowak’s project could revolutionize solar power generation, meeting the growing demand for renewable energy. Beyond solar plants, this technology could open new possibilities for personal and industrial lighting needs. The first experimental satellite launch is planned for 2025, and the company is optimistic about the project’s commercial viability.

Reflect Orbital is poised to become a pioneer in selling sunlight, potentially ushering in a new era of sustainable energy solutions.#
