Renewables


Dear all

I wrote this on 26th April 2008, but only had time today (18th May 2008) to upload it.

I wish all my Jewish friends a Chag Sameach this Pesach.

I wish all my Christian Orthodox friends a Happy Easter this weekend.

Further to my previous email, my Renewables research continues at a pace. I attach a slide that I am using as a basis for my research. Click on the image for a bigger version.

I would welcome anyone who wishes to get involved with a number of projects that I will be hosting over the next few months including:
solar water heating: buy or make?
photovoltaics: buy or make?
wind turbine: buy or make?

There is a lot of research that still needs to be done.

Besides this I will be buying some of the "toy" kits that are listed in the slide. If anyone would like to build them with me, please let me know.

I am looking for a school (or schools) that might be interested in learning about solar energy and I need some land for experiments, eg building a geodesic dome and building grey water systems. If anyone is interested, please let me know.

I am also looking for funding to fund these projects. Again, please contact me if you are interested.

I also need electricians, electronics experts, welders, gardners, etc. Please volunteer your time or services.

Love
David

Designing your own electricity system - part 7 (fridges)

Here are some specifications regarding energy saving fridges. Tafelberg sell some of the Ardo range of fridges. The Ardo rating is: 130KWH rating per year. Even if it really uses 165KWH per year, that will be amazing as an A++ energy star fridge is rated at 380KWH per year and a normal fridge much higher than that. My normal fridge (which I still need to replace) uses approximately 660 kwh per year which at 70 cents per kwh (my rate) is about R40 per month. Note that this is only based on one day's usage. After a few months, I will have a more accurate number. The Ardo fridge uses about 40Watts when it is on and is so quiet that a friend on mind has it in his passage outside two of the bedrooms. At 165kwh per year , the Ardo fridge costs R10 per month. A normal fridge is about R2000 and an Ardo fridge is about R8000. The difference is R6000, so R6000 / R30 (saving) = 200 months = 17 years. Not a very good payback period, but remember what I said in an earlier part of this blog s
