One thousand ice sculptures melt in the sun to highlight global warming,
an artist has come up with a cool idea to raise awareness of global warming.
London Daily Telegraph picture and words.
Whats global warming got to do with kit boats I hear you ask,well at one end of the scale,we can now start to consider not only the North West Passage but from news I heard recently,the Russians have now done the North East Passage,such is the effect of global warming on the ice always found in both regions.
On the other side we are informed that the national electricity supplier for South Africa,named Eskom,having increased tarrifs in the year 2009 by around 36% alone,now want a further tarrif increase of 45% per year for the next three years! in real terms this ammounts to 300% with it being a compound effect,the bottom line for myself is a roof mounted solar water heater in an attempt to reduce my daily electricity consumption,Eskom even pay you back 20 to 30% of the installation cost,thats an indication of how things are looking for our future?
We are no strangers to either solar or wind power,the boat has both and runs 24/7 a fridge and what ever lights we need,if the house was a boat we would not need Eskom,so we start to think about this line of attack,only this week we had an enquiry from Chris re what insulation should he use in his Lavranos GRP yacht? I told him to use a polyurethane foam as used in industrial applications,just a 25mm layer of that will stop most of the decks heat entering the boat,the difference is amazing.
So now Roy is tuned into things solar and whats next,well on 567 Cape Talk yesterday was a guy talking about heat reflective roof paint,they nearly cut him off as it was starting to sound like a sales pitch ( it was )however,the caller said' listen,I just want you to know the technology exists,you can use any suppliers paints' that kept him on air and he got his point across.
This was the basis of it:
Electricity and its higher end use and cost. Basically he is saying massive amounts of Eskoms power goes into air conditioning,he was talking about Malls and large office spaces with large roof areas but did say it can transform a normal three bed home for about R20,000,which costs less than buying one aircon,which then of course needs electric power? We were all listening by then I can tell you,its a NASA spin off from those heat shield tiles on the space ships,I know in summer our upstairs area is as hot as hell when no windows are left open,check out this Ausi site,I can not find the local lot,its named Ken Kote?
I find no mention of this particular KenKote but did find a company in Australia producing the same thing?

Whats on my mind is to use that on my boats decks,the none slip areas are a pale grey,which will soak in a fair bit of heat,possibly this heat reflective paint will reverse this?
