Happily, Orange has increased the number of Chill 'n' Charge tents to help make sure lines of communication stay open and - in what is now becoming as much of a tradition as Glastonbury itself - the company has announced the development of a new green charging technology. Previous projects have included a <a href="https://web.archive.org/web/20111013153051/http://www.gizmag.com/green-energy-charger-ready-and-pumped-for-uks-biggest-music-festival/11801/" target="_blank">Power Pump</a> and last year's <a href="https://web.archive.org/web/20111013153051/http://www.gizmag.com/thermoelectric-orange-power-wellies-generate-electricity/15346/" target="_blank">Orange Power Wellies</a>, and the latest prototype charger is no less impressive.

That’s exactly what is necessary, however, to allow power and data to flow to and from audio and other sensors mounted on the exterior of the vessels. Not only do these holes present a leakage risk, but they also diminish the hull’s structural integrity, <em>and</em> the submarine must be hoisted into drydock in order for any new sensors to be added. Now, a doctoral student at New York’s Rensselaer Polytechnic Institute (RPI) has come up with a method of using ultrasound to transmit power and data wirelessly through a sub’s thick metal hull – no holes required. <a href="/web/20111013153051/http://www.gizmag.com/ultrasonic-data-and-power-transmission-through-metal/18097/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> <a class="small" href="/web/20111013153051/http://www.gizmag.com/goodthinking/" style="float: left; ">GOOD THINKING</a> </div> <div class="clear_both"> <h2><a href="/web/20111013153051/http://www.gizmag.com/ibm-next-five-in-five/17391/">IBM's annual list of five innovations set to change our lives in the next five years </a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111013153051/http://www.gizmag.com/author/ben-coxworth/">Ben Coxworth</a></p> <p><em>17:15 December 28, 2010</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111013153051im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111013153051/http://www.gizmag.com/ibm-next-five-in-five/17391/#comments">12 Comments</a> </p> <p><img src="/web/20111013153051im_/http://www.gizmag.com/images/icons/splashyIcons/image_modernist.png" alt=""/> <a href="/web/20111013153051/http://www.gizmag.com/ibm-next-five-in-five/17391/picture/126877/">6 Pictures</a></p> </div> </div> </div> <center><a class="noback" href="/web/20111013153051/http://www.gizmag.com/ibm-next-five-in-five/17391/"><img src="https://web.archive.org/web/20111013153051im_/http://images.gizmag.com/hero/ibm5in5.jpg" title="IBM's Next 5 in 5 list predicts 5 technologies that will impact us in the next 5 years " alt="IBM's Next 5 in 5 list predicts 5 technologies that will impact us in the next 5 years "/></a></center> <div class="summary"> <p><a href="https://web.archive.org/web/20111013153051/http://www.gizmag.com/tag/ibm/" target="_blank">IBM</a> has announced its fifth annual <em>Next Five in Five</em> – a list of five technologies that the company believes “have the potential to change the way people work, live and play over the next five years.” While there are no flying cars or robot servants on the list, there are holographic friends, air-powered batteries, personal environmental sensors, customized commutes and building-heating computers. <a href="/web/20111013153051/http://www.gizmag.com/ibm-next-five-in-five/17391/">Read More</a> </p> </div> </div> <center class="snap_noshots"> <div class="next_prev"><strong> <span>1</span> <a href="/web/20111013153051/http://www.gizmag.com/tag/piezoelectric/2/">2</a> <a href="/web/20111013153051/http://www.gizmag.com/tag/piezoelectric/3/">3</a> <a href="/web/20111013153051/http://www.gizmag.com/tag/piezoelectric/2/">Next </a> » </strong></div> </center> <div class="dotsontop">  <div id="search_form_bottom"> <form action="https://web.archive.org/web/20111013153051/http://www.gizmag.com/search/" id="cse-search-box-bottom"> <span class="title">Looking for something?
