Sonofusion is a developing alternate energy technology that has the potential to replace polluting hydrocarbons which include fossil fuels. The economics for sonofusion appear feasible now with its application to heating large structures. Control of the environment where people shop and work could use sonofusion for space heating where more than 30% of our available grid energy in the US is used. The future of sonofusion has the potential for the complete replacement of CO2 producing fuels. This would have world changing economic, political, and environmental consequences.

cold fusion is real through sonofusion

Sonofusion energy is harvested from many billions of TCBs, transient cavitation bubbles, produced/sec in 1 cc of D2O, the volume of the device that experimentally produces around 40 watts of sonofusion heat. There is a big advantage using small devices as large sonofusion devices at 20 and 40 KHz (thousand Hertz) that I initially used were expensive and inefficient by comparison. Also the number of bubbles produced per acoustic cycle per second is greatly increased at the higher frequencies. In all devices the TCBs are formed by ultrasound. The small device is driven by a 1.6 MHz (million Hertz) piezo with D2O circulating through its operating system. As the D2O passes through the device, it carries Qx produced by sonofusion and Qa from the acoustic ultrasound input and (if the oscillator is in the D2O flow its heat is also included). So all the heat input Qi plus Qx can be used for heating. The D2O circulation keeps the device from overheating.

To help with the monitoring of the device and its D2O environment the SL, sonoluminescence, photon emission was measured using a photomultiplier. SL is always associated with TCB production and has been studied throughout the world for years, but is still not understood. This puzzle has support from a varied spread of theories. The advantage of SL measurements provides direct knowledge of the device's TCB plasma condition as photons are emitted relate to the dissociation of D2O into deuterons, D+.

Power is generated from TCBs produced in D2O. D2O fuel is found in ordinary water to the extent of one part in 6000 and is potentially a million years of the world's energy supply. The amount of energy that can be extracted from D2O is 1 million times that of gasoline. The cost of very high grade D2O is 50 cents a gram and this one gram is more than enough to power a car for its lifetime (Einstein's mc2). The car will wear out before running out of its fifty grams of fuel. The reaction product of this fuel is helium with no long range radiation by-products as measured in the Los Alamos National Laboratory and my twenty years of experience working with this cavitation process. Like the puzzle of SL, the lack of radiation products in the sonofusion phenomenon is explained by several published theories and is still controversial.

The experimental apparatus, data collected and its graphical representation are presented on page 2 and needs more explanation. The sonofusion device is very small and at this point is the size of a wristwatch weighing 20 grams, producing 40 watts, and using 1 gm of D2O. These small devices can be ganged together to form a battery like device of any size with a high energy density. To avoid overheating it is important to remove the heat quickly.

Experiemental. The 1.6 MHz piezo oscillator device, orange, drives the sonofusion device as the D2O, blue, is circulated through it by the pump. The D2O is saturated with Ar in the bubbler. In the circulation line are the pump, heat-exchanger, filter, sonofusion device, flow-meter, and bubbler. The heat-exchanger's H2O, light-blue, removes heat from D2O maintaining a constant temperature to the sonofusion device. The PMT, photomultiplier device, measures the level of SL photons that indicate the condition of the plasma in the final stage of the TCB collapse. These experiments require complete darkness

Data Plot. Graph I shows the resultant, purple , of three parameters (Qx, Qi, and SL) measured during the initial experiments of Series A with the low mass 1.6 MHz sonofusion device. SL, sonoluminescence, indicates the presence of the high density partial plasma from the collapse of TCBs in D2O. The TCB collapse process produces jets during the last stage of the bubble collapse. These jets contain D+ and e- plasma that are accelerated into a metal target where sonofusion takes place producing Qx, excess heat. Qi is the 60 cycle input from the wall which is related to Qa, driving the 1.6 MHz acoustic power oscillator. The acoustic input to the sonofusion device Qa equals 0.33 of Qi.
