Video: Sun has 'flipped upside down' as new magnetic cycle begins - Science - News - Th... - 0 views

  • The sun has "flipped upside down", with its north and south poles reversed to reach the midpoint of Solar Cycle 24, Nasa has said. Now, the magnetic fields will once again started moving in opposite directions to begin the completion of the 22 year long process which will culminate in the poles switching once again."A reversal of the sun's magnetic field is, literally, a big event," said Nasa’s Dr. Tony Phillips."The domain of the sun's magnetic influence (also known as the 'heliosphere') extends billions of kilometers beyond Pluto. Changes to the field's polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space."

Lights out: The dark future of electric power - opinion - 12 May 2014 - New Scientist - 0 views

  • We tend to think of such events as occasional, inconvenient blips. But in fact they are becoming increasingly common, and will only get more frequent and severe. This is because our electricity systems are more fragile than is commonly supposed, and are getting frailer. Unless we act, blackouts will become a regular, extremely disruptive part of everyday life.
  • The vulnerability of such systems is demonstrated by the Italian blackout of 2003. The event began when a falling tree broke a power line in Switzerland; when a second tree took out another Swiss power line, connectors towards Italy tripped and several Italian power plants failed as a result. Virtually the whole country was left without power. It says something when a nation can be brought to a halt by two trees falling outside its borders.
  • We predict that blackouts will occur with greater frequency and greater severity due to trends in both electricity supply and demand. Supply will become increasingly precarious because of the depletion of fossil fuels, neglected infrastructure and the shift toward less reliable renewable energy. Demand, meanwhile, will grow because of rising populations and affluence.

  • Between 1940 and 2001, average US household electricity use rose 1300 per cent, driven largely by growing demand for air conditioning. And such demand is forecast to grow by 22 per cent in the next two decades.

    While not a green energy story, it is relevant.  The reality is that our demand for power is growing quicker than the volume of power we can produce.
