Online radio !!!
Alternative energy field becoming an integral part of field development and production of electronics. An example is a completely new topic: Israel and the U.S. researchers are developing an innovative method in recent years to absorb energy from the sun using tiny online radio antennas.
These unintentional antennas TV or online radio frequencies known, but very short frequencies of electromagnetic radiation in the infra - red. This allows to produce electrical energy very efficiently, since the electromagnetic waves absorbed the antenna do not waste energy through heat.
Paper - Antenna - online radio
Recently introduced INL researchers from plastic sheet printed on 260 million thin metal molds, used receiving antenna electromagnetic energy from the sun. The idea is based on the most fundamental principles of antenna theory, which is designed resonance frequency antenna which is set to electromagnetic radiation, can become a source of energy if you join her circle of alignment whatsoever.
Online radio was the Idea ,This idea was illustrated by the - by the company Reitaon, which in 1964 introduced the idea of Rectenna: Microwave antenna RECTIFIERS, allowing microwave radiation to convert electric current directly. In the 80 developed in collaboration with NASA Reitaon more elaborate model based on dipole array antennas manufactured using a film - with a thin alignment diodes. The aim was to test the ability to transmit energy to remote installations such as ships or aircraft, using microwave radiation.
INL laboratory used these ideas, but to achieve another goal: instead of transmitting energy from afar Online Radio , they looked for a way how to absorb energy and "broadcast" from the sun regularly - and instead focus on microwave radiation - infrared waves to focus on - red closer to the optical field. In fact, they apply electronic techniques known to produce energy.
Innovation in TechTime
Israeli news site and high-tech electronics, TechTime, provides extensive coverage of these new areas. The site explains Shlmra electromagnetic Another advantage: the typical pattern of the transmit and receive antennas does not require just a line - a front view with the source of energy - hence the electromagnetic solar panel need not follow the course of the sun in the sky - to achieve maximum absorption.
The research began several years ago, after investigators concluded production techniques allow to produce small structures so small antennas, the resonant frequency will be infrared radiation - red. Next, several models were built using layered manufacturing technology, which allows to build a matrix of 81 spiral antennas are linked to each other. The antennas are built on a silicon substrate on which thin gold stripes Terms thickness of 200 nano - meter.
This basic structure has replicated several times in the technique of printing the result was a silicon slice of 8-inch diameter, containing 10 billion antennas. Next, open primary process that allows these antennas printed on a sheet of polyethylene, for - to get a flexible energy absorbing sheets.
New approach
It should be noted that this is an experimental project and everything is solved. However, this is an interesting exploitation of wireless communications elements to create solar energy. If the technological challenges will be resolved, will open wide cushion innovative applications, such as new insulation methods based on thermal curtains, mobile accessories bucket - supplier of energy in their immediate vicinity collections, utilization of energy wasted by heat and scattered. This is similar to another new field of incoming products and components electronics industry.
