cleggy2: This is how street lights work

The first electric street lighting in one Nelson suburb was powered by a small hydroelectric generator in the hills above the city. To switch the lights on and off, a chicken run was added to the power plant. At dusk every night the hens would go inside their coop and roost on a special hinged perch. This sank under their weight and connected a switch which turned on the street lights. At first light the hens would leave the coop, the spring-loaded perch swung back and the lights went out again.


Fantastic solution. Eat your heart out steam punk. There's a reason behind the saying about chickens coming home to roost -  they are so reliable, you can set your watch by them.

Geektastic: Here in the Wairarapa I would settle for a line network that did not fall over every time the wind got above 10kms!


To be fair, 10km a second is going to blow pretty much anything over! ;-)


Ok, 10 km's then...!


That's a distance not a speed... :-P


Next you'll be telling us parsecs refer to distance and not time...


Geektastic is the only geek to make the Wairarapa run in under 10 parsecs!

Ripple control is something that needs to come back into fashion, either in the traditional form or the more modern 'smart' version...

It's interesting how many 'smart' projects being developed, which are really just reinventing the wheel in a much more complicated way for what is generally a marginal improvement in effectiveness. I'm a fan of smart tech, but increasingly I'm wondering if some of the old ways are much more cost effective solutions to problems...
