The Mall of America Does Not Have a Central Heating System
By Chad Upton | Editor
In case you’re not familiar with the Mall of America, it’s a 2.5 million sq. ft. shopping center in Bloomington Minnesota, a suburb of the “Twin Cities” (Minneapolis and Saint Paul). The mall opened in 1992 and contains more than 520 stores, two seven story parking garages with a total of 20,000 parking spaces, a giant aquarium and of course an indoor amusement park.

I was there in 1993 on a big family road trip and it was amazing. A building of this size seems like it should have a massive heating system to stay comfortable during winter months. But, the engineers had a much more creative solution in mind. (more…)
The Vancouver Olympic Medals Contain Recycled Metal
I realize the Olympics ended yesterday, but I wanted to drop one final Vancouver Olympics secret. A week and a half ago, I did some research and crunched some numbers to get the value of an Olympic Gold Medal.
As our economy tightens its belt and the value of our natural resources strengthens, there is an increasing focus on reducing consumption while reusing and recycling where possible. The Vancouver games were no exception and they hold the title of the greenest Olympics to date.
The Vancouver medals range in weight from 500 to 576 grams. In a 30 part process that included 9 strikings, 1014 medals were created for the games. Part of the metal used was sourced from cathode ray tubes from old TVs and circuit boards from other discarded electronics. In fact, 6.8 metric tonnes of circuit boards were used.
The story behind the medals is almost as amazing as some of the athlete’s performances. If you’d like to see the story, you can watch it here.
Regardless of whether you believe in global warming or not, there is no doubt that our planet’s resources are endangered. That fact is one of the driving forces in the constantly increasing price of precious metals, oil, gas and other types of energy. Doing your part to reduce, reuse and recycle is good for the planet and will help your pocket book now and in the future.

How to Get the Best Price When Shopping Online
The internet has completely changed bargain hunting and finding the best price couldn’t be any easier.
I like to use Google products (formerly known as “Froogle”). It compares prices at thousands of retailers and show you the best deals along with ratings for each retailer.
Google products also searches sites like ebay. Although, it’s worthwhile checking ebay independently, there are lots of auctions for new products or if you’re willing to take a used one then you’ll get a great deal. If you’ve looking for something that doesn’t ship well, such as appliances, be sure to check craigslist.org or kijiji.com (owned by ebay). They let you search for products in your area so shipping is not necessary.
Sometimes the best price is at a website you’ve never heard of. This is when customer ratings and common sense are really helpful. If you’ve never heard of the retailer and can’t find a phone number for the office on the site, then I probably wouldn’t order from them. Amazon might be the only exception to this and in fact they’re one of my favorite online retailers, they frequently have the best price and their shipping and customer service are great.
If you’re searching for cameras, be weary of small companies based in New York City. They usually have the best price on camera equipment, but there are lots of online horror stories about some of these companies.
The Ideal Vehicle Speed for Best Fuel Economy
The precise number varies by car and environmental conditions, but the sweet spot is generally between 40-60 mph (65-95 km/h). Most small and medium size cars get the best mileage at about 50 mph (80 km/h).
A lot of factors affect the fuel economy of your car. Some of them don’t vary much with speed, such as the resistance of the engine pumps and accessories. Other factors, like the size of the frontal area and the drag coefficient create increasing resistance with speed.
The faster you drive, the more energy is needed to overcome the aerodynamic resistance of the car. Up to 40 mph, that isn’t really even a factor. So, if you’re driving a box then your best fuel economy is likely closer to 40 mph than 50. If you’re driving a teardrop shaped eco-car, then you’re likely closer to 60 mph. Of course, engine size and other factors are involved too. (more…)
Warm Your Car Up Faster
My friend Todd told me about this secret many years ago. He has rebuilt more cars in his suburban home garage than anyone I know.
I met Todd at my first part time job, we used to work early weekend mornings during high school. I was too young to have a driver’s license, so my dedicated parents would always drive me.
That was before remote starters, so I would usually start the car a few minutes before leaving. Actually, that’s not true — my Dad was usually the one starting the car a few minutes before I was ready to leave, which was about 10 minutes after I told him I would be ready to leave.
It didn’t make much difference to the car — it was still cold for at least half the trip. On the rare occasion that I started the car, I would turn the heater to its hottest setting and turn the fan to full blast. That’s actually the slowest way to warm the car, so lets talk more about the fastest way. (more…)
Why do Airplanes Fly at High Altitudes?
A few years ago, I was on a short, low altitude flight on a cold December evening in the Northeast. Because it was a short flight to a tiny airport, the aircraft was a small turboprop plane.
The flight was bumpy from the start. Somewhere in the middle, the flight crew was providing beverage service when the captain turned on the fasten seat belt sign. He instructed the crew to return to their seats and buckle up; before they made it to their seats, we hit a low pressure air pocket and the plane took a sudden drop.
It was just like a roller coaster making its towering first drop. We were in free fall for what felt like a really long time, but was probably only a couple of seconds. A few people flew out of their seats and hit their heads on the overhead bins, the crew was in the isle and did the same. Drinks, books, purses and other personal articles were thrown around the cabin, making a huge mess. (more…)
Botox can be Prescribed by Your Doctor
Botox is widely known as a beauty product used to reduce winkles.
It works really well for that because it prevents the neurotransmitters from contracting the muscles it is injected into. The wrinkles disappear because the muscle is completely relaxed.
Botox (botulinum toxin) is a toxin produced by botulism bacteria and it is extremely dangerous in sizable doses. Doses are measured in MU (mouse units). They’re called mouse units because it’s the quantity of toxin required to kill 50% of mice of a specific weight, strain and sex.
In fact, due to the prevalence of this bacteria in honey, it is not advisable to feed babies honey.
Despite its danger and common use for vanity, there are a number of reasons why your doctor may actually prescribe it. (more…)
Why Vinyl Records are Becoming Popular Again
By Chad Upton | Editor
There have always been cool record shops in the hip parts of town hocking vinyl to the enthusiasts. But, it had been a long time since the major record stores carried them, until last year.
Maybe you’ve noticed, maybe not. But if you’ve been into BestBuy recently, some of their stores have a massive vinyl record selection. A year ago, they had a few, now they have hundreds. It’s not every store, but some of them.
Vinyl Edition
For many people, it’s probably hard to imagine that anyone would go back to using records.
Records are not convenient to use. They don’t play for very long, about 26 minutes before you have to flip it over or put a new one on. You can’t easily skip songs at the push of a button. They have to be kept very clean to sound good. The needle drags on the record so the sound degrades over time and worst of all, they are expensive.
Since all of these drawbacks are easily overcome by digital formats like CDs and MP3s, it surely makes people wonder, why are vinyl records making a mainstream comeback? (more…)
How Much is the Gold in an Olympic Medal Worth?
By now, I’m sure many of you have caught some of the Vancouver Olympics. I was talking to my mom tonight and she thought it would be a good time for me to write about an Olympics Secret — I couldn’t agree more.
Since I live in the US, I’ve been watching the games on NBC. They’ve done a pretty good job of squeezing the excitement into a few hours of prime-time every night. It would be nice if it was all live, all day but they need to pay the bills. NBC estimates they will lose about $200 million broadcasting these games (the difference between what they paid for the exclusive rights and how much advertising time they can sell during the games).
I think the games have gone over really well, maybe better than NBC expected. I was talking to somebody today who was really surprised by their own excitement for these games. They were surprised because the Winter Olympics don’t always get the same hype and attention the summer games do. (more…)
Why Airplanes Don’t Always Fly in Straight Lines to Their Destination
If you’ve ever been on a flight equipped with a screen that shows the flight path, you might notice some zigs and zags that make your direct flight look like a scenic air tour. There are a number of reasons for this, but most of the time it comes down to Air Traffic Control (ATC).
Some people think that air traffic controllers are the guys that stand on the ground, waving lighted wands to guide the plane up to the gate. Those guys are actually part of the ground crew and they only have control over your flight for the last couple hundred feet before you reach the gate. The rest of the flight is controlled by someone else and it’s not the pilot.
The pilot flies the plane, but his course is being set by somebody on the ground. Those people are known as Air Traffic Controllers.
This system is a lot more complicated than it seems.
At the airport, the air traffic controllers sit up in the control tower. Those guys decide who gets to take off and land, which runways they use and when. They also direct planes that are moving around on the ground between gates and runways on the apron and taxiways. This aims to provide an organized flow of ground traffic and a safe flow of air traffic.
Once your plane has left the immediate area of the airport, the pilot must then communicate with a regional controller at an Area Control Center (ACC). If you’re on a long flight, you may get passed from one ACC to the next multiple times as you fly across the country.
