A Higgs boson event as seen in the Compact Muon Solenoid detector at the Large Hadron Collider. This one high-energy collision illustrates the power of energy conversion, which always exists in the form of particles. Energy plays a tremendous role, not only in our technology-rich daily lives, but in fundamental physics as well. The chemical energy stored in gasoline gets converted into kinetic energy that propels our vehicles, while the electrical energy from our power planets gets converted into light, heat and other forms of energy at our homes. But this energy always seems to exist as merely one property of an otherwise independently-existing system.
A new clip from the upcoming movie Black Panther was recently shown during an episode of Ellen. In the scene (which I assume isn't a spoiler, since it was on TV), the Black Panther is in pursuit of (or being pursued by) some people in another car. As the Black Panther rides on top of the car (which is, of course, the most efficient way to travel as a superhero), the bad guys are pelting him with bullets. Honestly, I shouldn't make such judgements--maybe they're not bad, just misunderstood.
Edison International is launching a business that will help reduce energy costs, improve efficiency and offer more environmentally friendly options for large energy users. The company's new subsidiary, Edison Energy, aims to serve commercial buildings, data centers, retail centers, healthcare operations and educational institutions nationwide. The new business recognizes sweeping changes affecting energy production and consumption, Edison International executives said Tuesday at a conference titled "The New Energy Future" held at UC Irvine. With growing opportunities to tap renewable energy sources, such as solar and wind power, and to employ energy efficiency and energy storage, consumers are seeking ways to reduce their utility bills and the impact of electricity use on the environment. Energy companies such as Edison also are working to navigate the changing energy landscape as consumers increasingly become self-generators of electricity.
Ever imagined using energy from your own rooftop solar panels to power all your air-conditioning units, heat up water and charge your smartphone? This can now be a reality. In Singapore, smart-enabled HDB flats to be completed in Punggol next year will allow homeowners to track energy consumption via a mobile app, and control just about any appliance that is connected to a power source. By 2040, one billion households and 11 billion smart appliances can actively participate in interconnected electricity systems, allowing these to alter when to draw electricity from the grid, according to the International Energy Agency (IEA). Other demand sectors, such as transport, buildings and industry, are also feeling the effects of a seismic shift in the energy sector.
Till now in this article series, we discussed how to optimise power consumption in BLE connected things to increase battery life and how to increase usable battery capacity of coin-cell batteries. The discussion was about getting the most out of battery. Talking about primary batteries, they also bring in other challenges. To address these challenges and to further increase battery life, an alternative power source comes to a rescue. In this part of the series, we will discuss the challenges imposed by primary batteries, and energy harvesting system.
