Good data

I got a lot of questions on that number from the end of my Ignite! talk.  As far as holmz is concerned, that number is close…  Let’s walk it through.

Let’s get our data straight:

• Vroom gets about 32 MPG;
• one gallon of gasoline comprises 1.3E8 joules; and
• its a 215 mile drive from Boston to NYC.

From that, if we use holmz’s calculator, then we can just run the formula “((215 [mi] / 32 [mpg]) * 1.3e8 [J/gal]) @ [kWh]” and the result is 242.6 kWh.

And now - to compare that against a 60 W power adapter for my MacBook.  If we go back to the calculator and evaluate “(last / 60 [W]) @ [day]” that gives me a result of 168.5 days. What’s a few days between friends?

I gave an Ignite! presentation on holmz at Ignite NYC II last night!  For those of you who don’t know, Ignite! presentations comprise 20 slides that are automatically advanced every 15 seconds - my slides conspicuously are absent of text, but I stuck them up on Slideshare anyway.

Once the video is posted, I’ll put a link up to that too.
