Generic Top Level Domain Names gTLD

Jun 23 2011 Published by under American Consumer, Corporate America, Geek stuff

 

ICANN has recently approved the new Generic Top Level Domain Names or gTLD. So how will this change the internet.

1. First thing that came to mind was better security for banks. A bank or finical institution can buy the gTLD and every thing that do can be tied to that gTLD. The user would not need to worry about phishing. there would be on confusion one what domain the e-mail or query is coming from. The only question are the Banks and financial institution willing to fork out $185k fork the security feature.

2. It will make things easier to find and shorter URLs. For example if Google were to buy the top level domain Google. You could access the different Google products by using URLs like. search.Google or Gmail.Google or Maps.Google.

3. The generic Top Level Domain will really help cites and geographic regions group there content or even create a revenue stream by selling domain name.  Example MannsTheater.Hollywood.

4. Other groups could also benefits like Plastic surgeons you could domai name like drBrown.PlasticSurgery or Dr.headman.PlasticSurgery.

These are just a few way that the new gTLD name might change the what we use the internet

PV panels and SMOG

Jun 22 2011 Published by under Geek stuff, Sloar, Uncategorized

Is smog a consideration when planing a photovoltaic solar system? Well in my very un-scientific analysis of my solar photovoltaic system production I have seen some patterns develop.

I have a monitoring system that constantly  collects data on how much the PV system produces every hour and instant production. One thing that I keep monitoring is what is the peak amount of wattage does the system produce.  I deduced that the closer we approach the summer solstice the more power the PV system would producre. General that is true, I have seen a constant increase in monthly production since the winter solstice.

But what I did notice is that for a couple of days after a rain storm the PV system was generating more power then on average. To the tune of 2 kilowatts (or about 5%) more. Two day after the rain storm the production would drop back to the lower average peak output.

The pattern was very constant (see chart below). Rain and then a couple of higher peek production days and then a return to the lower peeks. So I deduced that the days following a rain storm the air is cleaner, less smog. anyone can see, as they fly in the the Los Angelse basin, that most of the time there is thick layer of smog. So the smog is filtering the sun light and less sun is reaching the PV panels.

So you might argue hat the rain cleans off the PV panels. All the rain washes of the dust awasy and the panels receive more sunlight and therefore producer more power.  Sounds reasonable, BUT just recently we has a service clean the PV panels and both the day of the cleaning and the two day after the cleaning the power production was the average peek not the 2 kilowatts higher peek. Both day were also very sunny and cloud free.

So the more I look at the monitor reports, the more I’am convinced that the smog is costing me about 2 kilowatts a day in lower power production. All due to the SMOG levels in our area.

One response so far
