    Be smart – don’t pay any more electricity bills. more info: solar.xfollow.me (Copy to your browser’s address bar)

    Great job! I would like to see a cost analyst against our traditional energy producing methods like oil and coal.

    Thankyou very much. Very impressive!

    You may be interested in the “Suncube” photovoltaic solar tracker (website: greenandgoldenergy. com. au) that recorded a 34.1% peak efficiency only a few months after the SES’s solar stirling record.

    It looks like a “Reflective Stirling” vs “Fresnel Lens Photovoltaic” efficiency competition is afoot! :D

    i tried to send you some links twice but they failed both times.

    “your 50% figure might be something like ‘thermal efficiency’, which is a completely different concept.”

    your right, i am confusing the two concepts ^.^’

    look up appendix B solar sterling engine. they have an energy conversion efficiency of 31.25%

    “If they really converted 50%, people wouldn’t be bothering with solar photovoltaics.”

    they would if the economics were more feasable with photovoltaics.

    sorry to be a stickler, but can you give me more info please?

    Because i’ve looked into this stuff: Solar concentrator Stirlings generally convert around 23%-27% of the sunlight into energy. If they really converted 50%, people wouldn’t be bothering with solar photovoltaics.

    your 50% figure might be something like ‘thermal efficiency’, which is a completely different concept.

    some sterling engines are almost 50% efficient.

    are you sure that compressed hydrogen filled Stirling engines are more efficient than solar panels?
    Coz i know solar panels that are over 30% efficient.
    I don’t know any Stirling engine that efficient.

    Great video, a message that needs to be heard.
