Auto-Tracking Solar Powered BBQ

I had the opportunity to meet with the founder & CEO of California Sunlight yesterday, and check out their Auto-Tracking Solar Cooker:

The super-focus of a Fresnel lens allows the temperature of the device to be easily controlled, and with it's various attachments can be used as a solar oven, stove, BBQ, food dehydrator, water heater/distiller, and even a rotisserie. 

The thin, light & super-efficient Fresnel lens, originally used to distribute light in lighthouses, directs the sun onto a mirror inside the cooker's main frame, and is then directed to the chamber on the left where the cooking, heating, BBQing, etc. is done; the mini-solar panels on the right power the auto-tracker, ensuring that the solar chef never need adjust the cooker until the food or water is ready.  It can even be used indoors!

Here's a video that shows how it works:

Pretty cool if you ask me!

  1. This is a great find, thanks for sharing. I love how better and more affordable solar energy solutions are becoming. That thing does seem a little pricy though.

    1. Thanks Joe ~ yes, the ever-evolving affordability of solar technology is exciting, but it's the new & interesting ways that this technology is being used that is really inspiring! I really like how this solar cooker combines different technologies normally used for other purposes & fashions an entirely new design for solar thermal technology.

  2. The deteriorating situation in the environmental front has necessitated the change in the way we think about energy. best solar pathway lights

  3. It is awesome to see that a few people still invest an exertion into dealing with their sites.
