| For this, a safety factor should be introduced in the above value, of one microwatt per square centimetre. |
|
| But even if we went down to 1 microwatt per centimetre squared, it would be taking a huge step forward. |
|
| The power consumption of a typical solar-powered calculator, for example, is only about 5 microwatts, he said, and that of a typical digital thermometer with a liquid crystal display is one microwatt. |
|
| Well we are now in 2007 and I personally think that we have to be down at about a nanowatt, one thousand times lower than one microwatt, in order to begin to say, it's possible that's okay for chronic exposure. |
|
| The smallest, most efficient laser yet, a nanoscale device that consumes just I microwatt of power, could one day be a component of faster computers. |
