Ninety-two-year-old Peter Davey of New Zealand says he invented a unique water boiling gadget 30 years ago. He claims it uses sound waves, not a heating element, to boil water in seconds.
Davey noticed as he played the saxophone at home that everything resonated at a different frequency.
"The glasses will tinkle on one note. Knives and forks in the drawer will tinkle on another note and I realised that everything has its point of vibration," he said. "In the same way, a component in the ball is tuned to a certain frequency."
A retired engineering professor, Arthur Williamson, was invited to look at the boiler in action. He said:
"I don't know enough about sound to know whether you can transfer that amount of energy via soundwaves. I doubt it," said Williamson.
He did remember an alternative kettle years ago that had two perforated metal plates inside. The power ran between the plates, through the water. "The resistance through the water provided the load. I wonder if it isn't working like that? Without taking it to bits, you can't tell."
Someone, please, take it to bits.

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
