California-based inventor Peter Bevelacqua has launched a Kickstarter campaign for his latest creation, the Power Mole, designed to provide power to outdoor devices such as security cameras and decorative lights when outdoor outlets are unavailable.

The Power Mole comprises two puck-shaped components: the transmitter, affixed to the interior surface of a window pane, and the receiver, mounted on the exterior surface. The transmitter is connected to an indoor household outlet, while the receiver is USB hard-wired to the outdoor device. As an alternating electric current passes through the transmitter’s induction coil, it generates a fluctuating magnetic field that penetrates up to 30 mm of glass, inducing an alternating electric current in the receiver’s coil. A built-in rectifier then converts this AC current to DC, effectively powering the connected device.

Home automation and smart robots have transformed our kitchens, but a crucial element was missing until now: a reverse microwave to cool food instead of heating it. This groundbreaking invention, operational without electricity and emission-free, promises to revolutionize kitchen dynamics.

The absence of a reverse microwave until now can be attributed to the fundamental principles of thermal dynamics. Unlike heat, which can be readily added to objects through various methods, achieving “coolness” requires the removal of heat, dissipating it into the surroundings. The lack of a viable, electricity-free technique for rapid household cooling posed a significant challenge, with existing solutions being either small-scale projects or energy-intensive.

Machine vision, propelled by artificial intelligence (AI), has revolutionized our ability to interpret images, facilitating tasks ranging from autonomous driving to medical diagnostics. Now, researchers are pushing the boundaries of perception further by harnessing machine learning to observe human activity through walls using low-power radio frequency (RF) signals.

This innovative approach, spearheaded by scientists at institutions like Massachusetts Institute of Technology (MIT) and Washington University in St. Louis, offers a glimpse into unseen realms, enabling insights into daily activities without invasive monitoring devices or cameras.
