I. Introduction FOR the 2017 solar eclipse ballooning, the live streaming of the videos capturing the shadows of the solar eclipse was one of the main objectives. All teams who participated in the 2017 solar eclipse ballooning project were initially provided with a baseline ballooning system [1][2] that consisted of a ground station and four […]
Leveraging the natural adsorption–desorption exchange of water molecules from ambient air at the interface of a nanoporous mesh of protein nanowires, a team of researchers from the University of Massachusetts has demonstrated a durable form of energy harvesting that could potentially compete with solar cells on volumetric power density. By Julien Happich @ eenewseurope.com Publishing their

Using tiny arrays of carbon nanotubes, a team of researchers at Rice University has designed nanoscale incandescent light source that could be tuned to precisely emit at specific wavelength, based on the materials’ configuration. The so-called nanoscale thermal emitters described in a paper titled “Non‐Hermitian Selective Thermal Emitters using Metal–Semiconductor Hybrid Resonators” published in the journal of

As the world has become more environmentally conscious, we’ve seen an uptick in projects that monitor or control home energy use. At a minimum one of these setups involves a microcontroller and some kind of clamp-on current sensor, but if you’re looking for resources to take things a bit farther, this Raspberry Pi energy monitoring system

Bringing a product to market is not easy, if it were everyone would be doing it, and succeeding. The team at Pycno is in the process of launching their second product, a modular solar powered IoT unit called Pulse. It’s always interesting to get an inside look when a company is so open during the development

Miniature technology is a claim in today’s world. We talked recently about the tiny gyroscope which is the size of a grain of rice, and now clothes embedded with miniature solar cells the size of a flea can allow wearers to generate electricity outdoors, and charge items like mobile phones and smartwatches. The cell developed

The first step to designing a battery charger is choosing a battery charger IC from the vast field of available solutions. To make an informed decision, a design team must first clearly define the battery parameters (chemistry, cell count, etc.) and the input parameters (solar, USB, etc.). The team must then search for chargers that

The researchers at Soochow University in China, have published a paper on the hybrid device that is able to harness the power of sun and rain using a hybrid panel. By attaching a transparent nanogenerator to a silicon solar cell, researchers have designed a device that harvests solar energy in sunny conditions and the mechanical energy of falling raindrops in rainy conditions. The dual
