The sunspots are coming

Dangerous new groups of sunspots have unleashed a storm of huge solar flares which threaten grid connections worldwide, as astronomers predict two years of storms which could cause chaos on Earth. Airlines and energy suppliers are on alert as the largest solar storm in five years threatens to disrupt flights and power lines
Thirteen years ago these storms shut down the grid in Quebec, Canada.

It took just 92 seconds to kill the grid after solar flares bombarded the area, but far worse could be in store.  Brilliant scientist and sun-forecaster John Kappenman, a former energy company employee who now runs his own consultancy, says that in the event of a mega-flare which takes out  Earth’s power supplies, most other critical infrastructures such as water and food supplies will begin to crumble within a few hours.
But not all electricity sources will be equally affected.…

Grid can’t handle mass solar

Further evidence in favor of Micro-grids and against the so-called Smart Grid.

The runaway take-up of rooftop solar panels in Australia has undermined the electricity supply system, feeding so much power back into the network that it is causing voltage rises that could damage household devices such as computers and televisions. This means we should either rewire every home and every street, to suit the convenience of the big Utility companies, or rethink the way the nation’s energy delivery is organised. What applies to Australia is true elsewhere in the world.…

Solar powered clothes dryer

It’s funny how your perspectives change as you grow. When I was a kid, I used to be embarrassed because my mom hung our laundry out on the line to dry. I hated the smell of line dried clothes, sheets and towels, to me that meant we were poor, we couldn’t afford a dryer. All of my classmates had soft, fabric softener fresh smelling clothes, our clothes, towels and sheets were stiffer and to me were just second rate.
