Gallery: Rawlemon’s Spherical Solar Energy-Generating Globes Can Even H...


The solar energy designers at Rawlemon have created a spherical, sun-tracking glass globe that is able to concentrate sunlight (and moonlight) up to 10,000 times. The company claims that its ß.torics system is 35% more efficient than traditional dual-axis photovoltaic designs, and the fully rotational, weatherproof sphere is even capable of harvesting electricity from moonlight.

The ß.torics system was invented by Barcelona-based German Architect André Broessel. He sought to create a solar system that could be embedded in the walls of buildings so that they may act as both windows and energy generators. But the project isn’t only noteworthy for its solar efficiency capabilities –  the ß.torics  system is designed to generate lunar energy too!

The spheres are able to concentrate diffused moonlight into a steady source of energy. The futuristic ß.torics system is catching a lot of attention for its clean and beautiful design. (Despite solar power’s huge potential, we haven’t seen too many beautiful solar power technologies). We’re excited to see how architects will incorporate these energy generating orbs into alternative energy agendas and future building designs!

    What is the efficiency of solar cell alone ,you are using?

  2. nikhilpunnoose June 12, 2015 at 5:04 am

    What is the size of spherical lens and size of solar cell to get 35 % efficiency?What is the efficiency of solar cell alone ,you are using?

    Rather than focusing on a PV cell, it would be more effective to use a heat exchanger filled with molten salt. The heat could be stored for many hours (overnight at least) and used to boil water to turn a small turbine to generate electricity. PV’s and batteries are very inefficient compared to molten salt. Water boils at 212F so the light would not have to be sharply focused to generate the heat to get the salt over 700F, which would be more than enough to keep water boiling overnight.

    Been involved in PV and wind for sometime and this looks like something out of science fiction, lol!
    But I think the concept behind it is solid. Wonder what’s the wattage of the model in the pic?

    This could be California’s answer to the fried birds problem with their solar field. Studies are currently underway seeking a solution. This alternative could be the solution.

    I wonder how well this would work on Mars =)

    i need one ,for my domestic use can it generate ,tv,bulbs extra,i come across small of same,here and installed like bulbs on roof,whats your capacity in watts.

  9. Pete Kwok April 30, 2014 at 4:32 am

    As much as I like reading about solar power and energy:

    1) I’d like to know how much energy one of these systems is capable of harnessing. Typical systems can max out at 2kwh-5kwh…

    2) The system looks heavy and probably wouldn’t be able to sit on a rooftop of a garage or a standard roof?

    3) Is this something that can take advantage of the Feed-in tariff

  10. rlpridgen April 16, 2014 at 9:29 pm

    I wonder what one of those would cost for a resident home installation?

  11. Robert Goetz Sr April 15, 2014 at 8:38 am

    As a retired Electrician, I can truly appreciate the thought and engineering behind this. I would like to see how it functions in “Real-Life” applications in Building Construction and their related Electrical Systems.

  12. rosethyme April 15, 2014 at 8:32 am

    When would these be avaiable to individual homeowners? Love this!

  13. mshel April 15, 2014 at 5:13 am

    Has there been any developments with this project?

  14. trayc.vincent April 13, 2014 at 8:34 pm

    Do the Energy generating orbs/spheres come portable? like for people who rent if not they should, good idea I would definitely buy one :)
    Love the whole idea how it havasts electricity from the sun and the moon light. Way to help the people good on you.

  15. Alan Michelson April 13, 2014 at 4:52 pm

    The sunlight (or moonlight?) can strike the sphere at any angle, and the heat can be focused the way a magnifying lens works.

  16. Hervé Lemesle December 29, 2013 at 4:19 am

    Hello, I found this idea very interresting and would like learn more from this project about cost and weight of used materials. If it is 35% more efficiente as normal PV system with less carbon mark on Earth, what happen about installation of very powered system? What are the biggest power could it be wait from this type station? Is it install somewhere already?
    Well, continue to progress in your way because for future we will realy need Long-lasting(Sustainable) and renewable energy 😉

    Please contact me when these are available, Thanks – Jeff

    How big your balls have to be in order to generate 10KW ? and how is converted ?


  19. schauberger September 27, 2013 at 11:12 am

    i wonder about the price and the ecological-energy cost to produce this marvel …

  20. MJR54 June 5, 2013 at 12:03 pm

    Perfect candidate for being fabricated in orbit — in microgravity, molten glass would form sphere without any (or at least minimal) work by manufacturer.

  21. johnny frechette June 4, 2013 at 1:16 pm

    If that is solid glass it would take months to computer~cool to keep from cracking due to liquid(molten) center. Once this object is made it’s potential and workload is optimal and beautiful and maybe requires a wipedown once in a while.
    excruciatingly cool.

  22. Tara Mills May 12, 2013 at 2:46 pm

    Becca, you made me laugh because I had the exact same thought! I’d love one of these. I live off-grid.

  23. Gordy May 11, 2013 at 9:03 pm

    How much does it wiegh? the idea is brilliant.

  24. Judee Doyle May 11, 2013 at 9:25 am

    I want one in my backyard please!

  25. Sweetivy May 9, 2013 at 3:06 pm

    this fits a community project I\’m looking into providing workshops on. Every home in the world that has a roof or windows that wants power should have solar of some sort on it, in it or near it.

  26. gregvan May 8, 2013 at 5:43 am

    Is it solid glass, water filled or air filled? Weight? If filled with glass or water it would be very heavy…

  27. May 7, 2013 at 6:39 pm

    This is awesome and the designer is pretty hot too. :)

  28. Saylor Gilbert May 7, 2013 at 3:19 pm

    The cost, in money, time, and effort, to make the glass sphere alone makes me question the cost effectiveness of something like this. Something you could compare it to in difficulty is a giant telescope. When you start having curved glass at that size you run the major risk of it cracking or warming under its own weight, and when the smallest warp ruins its effectiveness to focus light you have to handle with extreme care. To me it appears that the only thing changing on this compared to conventional solar panels is that the sphere is able to focus the sun more effectively, 35% apparently. But if it costs 200% more than people on a budget will almost always opt for the 3 panels that together will generate more power, than the lone sphere. This being said it may not be made out of glass at all. And if it is they may be looking into alternative materials to lower the cost.

  29. Jonathan Kroiss December 31, 2012 at 8:32 am

    I wonder what the biggest size is that you could make one of these that should replace that stupid silver bean in Chicago.

  30. Jonathan Kroiss December 31, 2012 at 8:30 am

    still need to be careful with birds they might run into the glass lol

  31. Jonathan Kroiss December 31, 2012 at 8:29 am

    Hey Tony Stark called he wants his Incredibleness back

  33. dlevy2013 October 22, 2012 at 1:26 am

    This is great! Would make an epic solar steam engine! Have you looked into this potential?

  34. bubbarago September 23, 2012 at 8:33 am

    reminds me of the crystal sculls put it in the pyramids and see what happens. make one out of crystal next.

  35. bharani kumar September 21, 2012 at 9:18 am

    Hi Bro,

    Can U give us the estimation

  37. SolarBest September 19, 2012 at 11:49 pm

    Would very much appreciate the opportunity to learn more about the system if you are in a possion to share with an NDA/NCND in place.
    We are preparing to do a project in PR; would you consider allowing for Distributorship or License?

  38. MsLiberty September 19, 2012 at 1:03 pm

    How much???

    Could this technology be used to heat my pool and spa

  41. ---hurtzdonut September 19, 2012 at 1:09 am

    Is this a different technology than solar technology or a more powerful version in a prettier form? From someone who doesn’t know the difference.

  42. sundramurthy September 18, 2012 at 10:18 pm

    wonderful invention. Bro keep it up.Feature really need your help.

  43. feminva September 18, 2012 at 9:42 pm

    Wow… this is exciting … seems beautifully artistic/pleasing to the eye and psyche (calming) standing alone or incorporated into a structure.

  44. justusnak September 18, 2012 at 9:39 pm

    Amazing! How would someone get in touch with the maker of these, and get a quote? Or, are they even available to the public yet!?

  45. peaceful September 18, 2012 at 5:30 pm

    I’d like to know the costs of one of these for a residential backyard for onee who would like to get off the grid. Is there a practical use for the residential use?

  46. florencemb September 18, 2012 at 2:21 pm

    How about using small marble-size water filled glass bubbles for anyone to use?
