[Wayne] found an interesting device called a Micro Blower that will blow small amounts of air from a small, lightweight device. A few modifications later, and he had a piezoelectric vacuum pump ...

In our design, by using a properly rated submersible pump, the water delivery system can be considered electrically safe. Air from the leaf blowers is also delivered to the foam cone by pipes ...

An international research team has developed a novel solar-air dual-source heat pump (SAHP) for water heating applications. The system's innovation lies in using a blower fan that enables forced ...
