Harvesting unused energy with flat thermoelectrics
09 April, 2013A large proportion of the energy we produce disappears unused into thin air via waste heat. Tiny thermoelectric generators can tap this potential, whereby the electricity is produced by way of temperature differences. However, so far their production has been laborious and expensive.
CSIRO explains the mystery of ball lightning
21 January, 2013Australian scientists have unveiled a new theory which explains the mysterious phenomenon known as ball lightning.
Producing AC voltages by manipulating magnetic fields
08 January, 2013Scientists are putting a new spin on their approach to generating electrical current by harnessing a recently identified electromotive force known as spinmotive force, which is related to the field of spintronics that addresses such challenges as improving data storage in computers.
