However, what if all that power could be harnessed to produce cheaper and more efficient electricity? This is just what Canadian engineer Louis Michaud proposes to achieve, with an invention dubbed the “Atmospheric Vortex Engine” (or AVE).  <a href="/web/20130116011732/http://www.gizmag.com/vortex-engine-tornadoes-electricity/25508/" class="readmore_link">Read More</a> </p> </div> </div> <div class="summary_item " data-article="25512"> <div class="summary_details"> <div class="clear_both"> <h2><a href="/web/20130116011732/http://www.gizmag.com/citisense-air-quality-monitor/25512/">Portable sensor lets users monitor air pollution on their smartphone</a></h2> <div class="summary_details_left"> <div>By <a href="/web/20130116011732/http://www.gizmag.com/author/ben-coxworth/">Ben Coxworth</a></div> <div class="date">December 19, 2012</div> </div> <div class="summary_details_right"> <div class="has_comments"><a href="/web/20130116011732/http://www.gizmag.com/citisense-air-quality-monitor/25512/#comments">3 Comments</a></div> <div class="has_pictures"><a href="/web/20130116011732/http://www.gizmag.com/citisense-air-quality-monitor/25512/pictures">3 Pictures</a></div> </div> </div> </div> <a class="noback hero_link" href="/web/20130116011732/http://www.gizmag.com/citisense-air-quality-monitor/25512/"><img src="https://web.archive.org/web/20130116011732im_/http://images.gizmag.com/hero/citisense.jpg" title="The CitiSense sensor provides smartphone users with real-time air quality readings for the..." alt="The CitiSense sensor provides smartphone users with real-time air quality readings for the..."/></a> <div class="summary"> <p> Air quality is one of those things that many of us should be more concerned about, but aren’t. According to some people, this is because we’re not easily able to know how clean the air around us really is – we just assume it’s “clean enough.” Computer scientists at the University of California, San Diego have set out to change that. They’re developing a compact, portable air pollution sensor that communicates with the user’s smartphone, to provide real-time air quality readings for their immediate surroundings.  <a href="/web/20130116011732/http://www.gizmag.com/citisense-air-quality-monitor/25512/" class="readmore_link">Read More</a> </p> </div> </div> <div class="summary_item " data-article="25399"> <div class="summary_details"> <div class="clear_both"> <h2><a href="/web/20130116011732/http://www.gizmag.com/renewable-energy-reliable-study/25399/">Renewable energy is reliable, new study claims</a></h2> <div class="summary_details_left"> <div>By <a href="/web/20130116011732/http://www.gizmag.com/author/antonio-pasolini/">Antonio Pasolini</a></div> <div class="date">December 13, 2012</div> </div> <div class="summary_details_right"> <div class="has_comments"><a href="/web/20130116011732/http://www.gizmag.com/renewable-energy-reliable-study/25399/#comments">28 Comments</a></div> </div> </div> </div> <a class="noback hero_link" href="/web/20130116011732/http://www.gizmag.com/renewable-energy-reliable-study/25399/"><img src="https://web.archive.org/web/20130116011732im_/http://images.gizmag.com/hero/energystudy.jpg" title="A new study claims that a municipal grid could be powered almost entirely via renewable so..." alt="A new study claims that a municipal grid could be powered almost entirely via renewable so..."/></a> <div class="summary"> <p> Although critics of renewable energy may claim that it isn't reliable enough to power a grid, a new study gives proponents of clean power – such as wind and solar – fresh ammunition to respond. A thorough analysis carried out by the University of Delaware and Delaware Technical Community College concluded that renewable energy could reliably power a large electrical grid 99.9 per cent of the time by 2030, at a cost that matches today’s electricity prices.  <a href="/web/20130116011732/http://www.gizmag.com/renewable-energy-reliable-study/25399/" class="readmore_link">Read More</a> </p> </div> </div> <div class="summary_item " data-article="25430"> <div class="summary_details"> <div class="clear_both"> <h2><a href="/web/20130116011732/http://www.gizmag.com/cappa-compact-hydropower-generator/25430/">Ibasei's Cappa provides hydroelectricity on a small scale</a></h2> <div class="summary_details_left"> <div>By <a href="/web/20130116011732/http://www.gizmag.com/author/darren-quick/">Darren Quick</a></div> <div class="date">December 12, 2012</div> </div> <div class="summary_details_right"> <div class="has_comments"><a href="/web/20130116011732/http://www.gizmag.com/cappa-compact-hydropower-generator/25430/#comments">19 Comments</a></div> <div class="has_pictures"><a href="/web/20130116011732/http://www.gizmag.com/cappa-compact-hydropower-generator/25430/pictures">4 Pictures</a></div> </div> </div> </div> <a class="noback hero_link" href="/web/20130116011732/http://www.gizmag.com/cappa-compact-hydropower-generator/25430/"><img src="https://web.archive.org/web/20130116011732im_/http://images.gizmag.com/hero/cappa_hydropower.jpg" title="The Cappa compact hydropower generator can deliver 250 W of electricity" alt="The Cappa compact hydropower generator can deliver 250 W of electricity"/></a> <div class="summary"> <p> Despite being the most widely used form of renewable energy worldwide, hydroelectricity is generally reserved for large-scale commercial installations built around massive dams.
