Community Day at the Harris Nuclear Plant

Today Progress Energy hosted Community Day at the Harris Nuclear Plant. I live with in the 10 mile radius of the plant and the Harris Plant has been a good neighbor of mine for the 21 years I've lived here. Progress Energy mails me safety information each year which I scan and leave next to the phone in the kitchen. Progress Energy also supplies clean low cost carbon free energy to my home, and along with the other nuclear plants, 40% of the electricity to homes in the carolinas (nuclear power supplies about 20% nationally).

Years ago I had went to the Harris visitor center and viewed the displays. The control room simulator where they train nuclear plant operators was closed on that too long ago visit. The simulated control room is an exact copy to the actual one in use at the Harris plant. Now days the control room simulator is only open to the public this one day a year (generally the last Saturday in August)
, so the chance to take the control room simulator tour made today's visit a must do. The tour is available by reservation for schools and clubs. Kids get to have all the fun!

As luck would have it they were rebooting the simulator during my tour so all the dials, gauges, lights, and displays in the simulator control room were off. I didn't get many pictures this time, but I did get to ask a lot of questions. I also got to see the the computer room that runs the simulator.

Today while I waited for the control room simulator tour to start I visited the booths they had and spoke to the Progress Energy representatives. I learned that their certificate to operate the current reactor at Harris plant has been renewed for another 40 years of operation. I also found out there is 140 years of wet storage in place at the Harris plant. That after 5 years in wet storage that the spent fuel can be moved to dry storage. There is no dry storage at the Harris plant, but I believe that the spent fuel storage problem will be solved in the next 100 or so years. A Traveling Wave Reactor which Bill Gates spoke about at the 2010 TED (Technology Entertainment and Design) conference seems to be very promising solution to the spent fuel problem.

I was pleased to see the solar voltaic sign in front of the visitor center along with a PHEV (Plug in Hybrid Electric Vehicle) Ford Escape. As a BEV (Battery EV) owner I'm a big supporter of EVs and I'm very interested in carbon free ways to produce the electricity needed to charge them. Carbon free renewable energy like the solar voltaic are a part of the answer, but for that enormous base power we need nuclear. Period. So get over it. Go visit a nuclear plant near you. They are a good neighbor and will welcome you and keep you warm on a cold windless winter night.

Burning Up

So it's been hot lately. I've been burning up in this heat. I've never liked the heat and humidity we have here in the south even though I've grown up with it. All the heat has made it difficult to run in the evening. It was still 85F (29.44C) at 9PM last night, so I've been running on a tread mill I purchased from Larry a couple years ago before he moved to Arkansas. It's a good, powerful, full size tread mill and it easily handles me. It has some nice features:
  • digital speed and incline controls
  • time and distance traveled
  • calorie burned
It also allows you to set a calorie burn goal, and when you reach your goal the belt slows, and in a few seconds, stops. Since my favorite part of exercise is when it is over, I like anything that will get me to my favorite part. So I set the burn goal for a whole box of mac & cheese (2 servings, or 500 calories) and started jogging. I was surprised when the thread mill shut off in about 25 minutes, way short of the 40 minutes I was expecting.

So is the 75 calorie for 6 minutes of jogging I used wrong, or is it the calorie counter on the tread mill? Well they are both wrong, and probably for the same reason. Both assume some weight value and chances are I'm not that weight. Well there are calorie calculators all over the web. But very few provide the formula. I found a formula that most scholarly pages site is from Energy Expenditure of Walking and Running, from Medicine & Science in Sport & Exercise, Dec. 2004.
Your Total Calorie Burn/Mile Your Net Calorie Burn/Mile
Running (>5mph) .75 x your weight (in lbs.) .63 x your weight
Walking (3-4mph) .53 x your weight .30 x your weight
Total Calorie Burned (TCB) includes your basal metabolism (what you burn just sitting there), and the Net Calorie Burned (NCB) is just what the exercise burned and is what typically gets shown by calculators.

So just how long do I have to spend on the tread mill to burn up 500 (total) calories? Ever how long it takes me to go 3.12 miles if I run, or 4.4 miles if I walk. So 37.5 minutes based on 12 minutes per mile pace which is about right or me. When walking your center of gravity does not move (up and down) as much as when you run, so you don't burn as many calories. That is an overly simple explanation. How Many Calories are You Really Burning? is a good place to start reading if you want specifics. Also exercising on a tread mill or on a track is about the same. But a flat track and the hills in your neighborhood are of course, different. Proving once again your mileage will vary!

What would you do for some Macaroni & Cheese?


So, I'm trying to lose a few pounds (a stone or so for you Brits, not money) and was wondering what was a calorie that I see on those labels all the time. I knew that a calorie was a unit of energy so with a little searching I found a handy California Energy Commission web page What is Energy?
The California Energy Commission web page says a piece of buttered toast contains about 315 kilojoules (315,000 joules, or 75.28 food calories) of energy. With that energy the web page says you could:
  • Jog for 6 minutes
  • Bicycle for 10 minutes
  • Walk briskly for 15 minutes
  • Sleep for 1-1/2 hours
  • Run a car for 7 seconds at 80 kilometers per hour (about 50 miles per hour)
  • Light a 60-watt light bulb for 1-1/2 hours
  • Or lift that 5 lb (2.26 kg) sack of sugar from the floor to the counter 21,000 times!
Sort of helps you picture just how much effort it takes to burn off a 250 calories candy bar - like lift that sack of sugar 70,000 times.
I can't confirm or explain their numbers. I did the metric-English conversions for this post, but I've heard before that running a hour is about 700-800 calories burned, so I suspect they are in the ball park (on the pitch). I suspect 75 calories is low for a piece of butter toast, but 315K joules is 75.28 kilo-calories (aka food calories).
I think on food labels they should put "Jog 20 minutes after eating this" or other depressing (but meaningful) warnings on the labels.
For me? What will I do for mac & cheese? I'll just take a 5 hour nap.

2010 Peachtree

Peachtree 2010
I'm sure you all noticed I've not posted much this year. Not a lot going on. Just work mostly. I did run in the Peachtree this year. This was the 2nd time for me. I cut 10 minutes off my time this year. Mostly because it was cooler and much less humid. That and I drank more before and during the race. I think last time I struggled because I got a bit dehydrated.

Again with the Cables

Hello and Happy New Year!
For Christmas I got myself and new Blu-Ray DVD player with internet video streaming (aka Netflix). Beside watching Blu-Ray and regular DVDs I can also watch movies streamed 'on demand' from the internet. The Blu-Ray player is connected to the internet using the the Wired Ethernet port I installed next to my 'media cabinet.' But to hook up to the plasma I needed to run a second HDMI cable from the Blu-Ray in the media cabinet to the plasma.

The media cabinet is actually in a closet that shares a wall with the den. In the den my plasma is mounted on the fire place hearth. The picture shows the plasma just after I hung it a couple years ago. If you look closely you'll notice there are no cables connected to it in that picture. Sort of reminds you of those commercials where a handsome couple sit watching their flat screen hanging cable free on a perfectly clean wall. If you read the disclaimer that flashes up during the commercial it says 'simulated picture shown' - most people believe they say that to make an excuse for why their super HD picture looks so bad on your crappy TV. But I know different. They 'simulate' the picture because you can't get a real picture on a flat panel without running lots of cables to it! And cables showing can really spoil the picture - which I'm sure some readers know too well.

Well over the last couple years as I hooked up various devices to my flat screen plasma and cable (mis) management got to be a real problem. No perfect picture here.

On the lower left you can see the hole in the wall the cables use to pass through to the closet on other side. I never finished the opening. I have enlarged the hole as I ran more cables through it.

The Blu-Ray used the last remaining connection on the plasma's input panel, so with no more cables possible I decided it was time to finish off 'the hole.' I also wanted to hide the cables. The next picture shows the finish outlets with the new connectors. 2 HDMI, 2 component video, 1 video, external antenna, 3 speakers cables, sub-woofer, and power cords.

Not bad. Much neater for sure. I ended up adding a 2nd opening for speaker wires for the surround sound. The black bundle of (13) cables snakes up the side of the bricks. Way better than it was, but I was still not happy.

While staying with Dexter and Jan in Atlanta for the Peachtree Road Race I noticed Jan had put their cables inside of a tube she made out of fabric. It was gathered fabric and I thought it looked nice and did a good job of hiding the cables. I don't have access to a sewing machine, so Gale suggested I just make the hem using glue. Then use hook-and-loop along the edges of the fabric so when fasten it would form a tube. So I took a shot at it and made my own cable tube!

I don't have Jan's sewing skills so it does not gather as nice as hers. My fabric also does not match the wall paper like hers (Wall paper? What wall paper? I anit got no wall paper in my house!). But, I think it turned out pretty good. Doesn't look like a snake crawling up the wall now.

So after about $150 in cables and connectors, a bit of fabric and glue I'm having a Happy New Year!

I Remembered my Camera

Toronto
So I had another quick trip up to Toronto this last week. We needed to be there Monday AM so Wally and I flew up Sunday. We decided to take a late morning flight so we have time to do a bit of sight seeing. I had been to the Rogers Center on a earlier trip but forgot my camera, so I didn't get any pictures. I got a few this time.

Oh BTW - I'm on Facebook now. Look me up, and let's connect.

1223 Vs 858


So I picked up a pair of New Balance 1223 to replace my 2 year old 858 at the New Balance Outlet store in Lawrence, MA. In the store I had a new 858 on one foot and the 1223 on the other and liked the 1223's better (they were the same price). So when I got home I was surprised when I ran that the 1223s sort of jarred me way more than I remember the 858s did. So next day I ran in my old 858s and sure enough THEY JARRED ME more than the 1223s! WHAT!

So I'm now running in the 1223s. Moral of the story: Don't take 4 days off from running before buying shoes!
