Eerie Glowing Green Sea near Hunterston Power Plant
23 January 2012
The sea near a Hunterston nuclear power station in Scotland is glowing lime-green, according to a set of satellite photographs.
A local resident raised the alarm when they spotted a luminous green patch on the satellite photos surrounding a nuclear power station on Google Earth.
And according to the images, there is an equally vivid area visible inside the satellite boundary at Hunterston nuclear power station in Ayrshire.
But according to the energy company that generates electricity from the Hunterston B reactors, the luminous green waters can be explained by a simple explanation.
A spokesperson for EDF energy said that "bubbling water" is causing the glowing green patch to appear on the satellite images.
According to the French energy company, the nuclear plant takes in large amounts of seawater to cool its reactors, and then discharges it back into the sea.
The greenish area at sea is where the warmed water bubbles up from the pipeline, and the greenish area on the site is a shaft through which the water surges.
A spokesperson for EDF said: “The Google shot taken offshore is where out-cooling water exits a pipe and enters the sea, producing a bubbling effect.”
“The other photograph is of our surge shaft, which the cooling water passes through.”
Critics agreed that the green glow was probably not caused by radioactivity, but argued that nuclear power had other drawbacks.
Peter Roche, a nuclear consultant and former Government radiation advisor said: “No matter how green the glow from Hunterston it cannot make nuclear power as environmentally sound energy source.
“We still have nowhere to put the highly dangerous waste and there are continuous reports of health problems associated with radiation emissions even without any accidents like Fukushima, Chernobyl and Three Mile Island.”
Building an Energy Efficient Green Access Control System with Borer Data System.
The cost of energy to power a door access system is seldom taken into consideration. With the cost of energy escalating and set to increase substantially over the coming years, energy costs should not be left out of the purchasing decision.
As an illustration, here is a calculation for the cost of energy to power a 100-Watt domestic light bulb assuming it is left illuminated for one year: -
0.1kW (100 Watt light bulb) x 24 (hours in the day) x 365 (days in the year) x £0.106 (cost of 1kWh of electricity) = £92.856 (cost of energy for one year)
Using these figures as a guide we can easily calculate the cost of energy for an access control system. Competitive Legacy access control systems often consume around 85 Watts or more for each door controlled (hence if a 100 Watts light bulb cost £92.856 then 85 Watts will cost £92.856 X 0.85 = £78.93 to power one door for one year).
It therefore makes sense to calculate the total lifetime costs of each of the systems under consideration taking the following costs into account: Purchase Price, Infrastructure, Labour and Energy.
Do not simply assume that all systems are equal and purchase the system with the lowest price tag because it may end up costing the Earth.
