The MIT solar thermoelectric generators are made through a nanostructured process, and have no moving parts, unlike other such systems that typically involve vast arrays of movable mirrors that track the sun and focus its rays on a small area. The generator is, instead, placed inside a vacuum chamber made of glass, and covered with a black plate of copper that absorbs sunlight, but does not re-radiate it as heat. The other side is in contact with ambient temperatures and, when placed in the sun, the entire unit heats up, even if it is not directly facing the sun. The unit requires much less material than conventional photovoltaic panels, so it could be much less expensive to produce. Gang Chen, MIT\u2019s Carl Richard Soderberg Professor in Power Engineering and director of the Pappalardo Micro and Nano Engineering Laboratories, and a co-author of the paper published in the journal Nature Materials, said the concept \u201cis very radical.\u201d Chen said the new system won\u2019t be a substitute for solar photovoltaics, but does offer another way of tapping into solar energy. It can also be easily piggybacked onto the existing solar hot-water industry, with \u201cno subsidies required,\u201d Chen said. \u201cIt can be a game-changing thing.\u201d<\/p>\n<p><a href=\"http:\/\/web.mit.edu\/newsoffice\/2011\/flat-solar-thermal-0502.html\">http:\/\/web.mit.edu\/newsoffice\/2011\/flat-solar-thermal-0502.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Massachusetts Institute of Technology (MIT), United States, have developed an unusual, high performance way of turning the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[34],"tags":[],"class_list":["post-2347","post","type-post","status-publish","format-standard","hentry","category-technology-update"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
