Consumer electronics companies gathered last week at the Greener Gadgets conference in New York City to showcase their green designs and products. One product on display, the HYmini, offers a green solution to powering portable electronic devices.
The HYmini is a hand-held solar- and wind-driven power bank that uses a small fan to generate energy for electronics. For additional power generation, solar cells can be added onto the unit where the produced energy is stored.
“The HYmini is actually a gearless generator; everything is actually controlled through the circuit board and its analog IC,” says Arthur Huang, managing director of HYmini. “It is different than the conventional gear system; you can blow at it and it has enough voltage to charge into the battery.”
The HYmini can be used to provide a 5V charge to MP3 players, digital cameras, cell phones and PDAs. The device uses a USB transfer cable to deliver power to mobile devices and has various connectors for different devices. The HYmini also has an AC/DC wall adapter.
The HYmini attaches to bike mounts and armbands to give athletes or active individuals the ability to charge their devices on the go. “HYmini is basically a first step that will make people think charging green is an active thing; it’s a cool thing to charge actively,” says Huang. The HYmini is sold for $50 as a base unit with solar panels, bike mounts and arm bands sold separately.
Arthur Huang presents the HYmini to visitors at his product booth during the Greener Gadgets conference.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
