The Price Of Fluids

Sunday, September 5th, 2010

I read this article at ABC news stating that the bottled waters Aquafina and Dasani are really just municipal tap water, filtered one more time. One of the sources of Aquafina is the Detroit River. ABC had various bottled waters and various municipal tap waters sent to a lab. All were equally safe. ABC then did a blind taste test using avowed bottled water fans. Among the unscientific results were tap water being the winner some of the time and the most expensive brands of bottled water not winning at all.

Since I had some shopping to do today I decided to write down the price of various fluids as I visited my local gas station and my local supermarket. This is part of what I found:

 Fluid   Price Per Gallon   Commentsnbsp;
Aquafina $5.68 owned by Pepsi
Dasani $4.76 owned by Coke
Gasoline $2.64 cheapest gas at Shell
Tap Water $0.003 $2.71 per 1000 gallons

I got the price for my tap water off of my water bill. My municipality has an impressive water treatment facility. When I called them to ask them about the quality of the water I got to talk to an engineer, very proud, who gave me a very long lecture. My only problem with my tap water is that during the winter time it is contaminated by the run off from snow melting. Their solution is to put enough chlorine in the water that I can smell it when I draw a bath. My solution was to buy a Brita water pitcher for about $20. Very cheap, very convenient. Problem solved.

Western tastes for diets rich in meat and dairy products are unsustainable as the global population surges towards a predicted 9.1 billion people by 2050.”

This is exciting news.

Electric passenger cars would solve so many large problems. However, range has been an issue. The best only last for about 150 – 200 miles between charges. A charge on a home charger can take up to 8 hours.

Enter JFE Engineering with an industrial strength charger that can give a small EV an 80% charge in just five minutes. You read that right, five minutes. About the time it takes to get gas.

If that news wasn’t good enough, hold on. MIT has just licensed battery technology to a private firm. The technology uses carbon nanotubes which can make the batteries store 5 times as much energy as a conventional ultracapacitor.
