| Radio Energy Harvested With Inkjet-Printed Antenna |  |
| judgecorp writes "Everlasting green energy for RF tags and other low-power devices could be possible as scientists have harvested energy from ambient radio waves using cheap antennas printed by an ordinary inkjet. The scientists, from Georgia Tech, started at 100MHz but have now produced systems which scavenge power at up to 60GHz, allowing them to draw power from most of today`s major radio technologies."

| How to Improve Wind Energy Reliability with Cable Standards | |
| When it comes to advancing technologies for alternative energy, there are many issues to consider. Those that impact the system`s efficiency, reliability and life-cycle cost should be at the top of the priority list. For example, it`s important to be sure that the cables specified for the wind farm align with the standards of the larger grid. To specify anything less is short-term thinking that could result in lost revenue due to downtime, expensive repairs and negative publicity. |
