Triple Solar Thermoacoustic Engine Makes A “Bizarre Sound”

Have you ever heard anything like this?  The home experimenter shows us a really cool device.  It almost sounds like when you take a glass with a stem, fill it with water and circle it with your hand, making a strange sound.

Made in 2003 for an outdoor science park exhibit. Three fresnel lenses focus sunlight onto three standing-wave thermoacoustic engines. The light passes through the pyrex caps of the resonators and onto the hot side heat exchangers. See accompanying close up video showing one of the engines in more detail.

Note: Do not try this at home and/or without the supervision of a professional.

When you hear this you might think you are on another planet 😉

Let’s listen to the sound that this device makes in the video on page 2

    Imagine if scientists create the world into a spaceship itself?
    By first creating a heat source to resemble the sun an give off the same thing as the sun does & is a sustainable distance from the earth as well as having some sort of magnet to resemble the pull force of the moon, we just keep the power source & gravitational pull a close but safe distance from (earth) as we move threw space searching for other life forms.

    I fail to see why this is surprising or weird to any one all energy is, is vibrations. Some exist with our perceptible spectrum others do not.
