1/3 We are devastated by the passing of Susie Buda yesterday. Susie was an incredible joy and talent, and the world is less today without her. She developed into one of the best staffers in the Senate, and we were thrilled with the time we had with her. ...

The 5.59x10^13 MJ delivered by gas pumps > 1.5x10^13 total electricity produced. Draw your own conclusions, but the way I see it, we don't generate enough electricity to power the fleet even if we give up ALL other use of electricity. (Unless my Nuke friends get on it!!!) (6/6)

Per day, this is 1.53x10^11 MJ of energy delivered, or an annual total of 5.59x10^13 MJ delivered by gas pumps. In comparison, I looked up that in 2018 the US produced 4.17x10^12 kWh or 1.5x10^13 MJ of electricity in 2018. (5/X)

Using the 15gal/90s delivery rate to calculate the energy transfer from each pump and the stated assumptions, I calculated an average energy delivery rate of 20.79 MW per pump, when it runs. (4/X)

Gasoline has 44 MJ/kg, and a density of 748.9 kg/m^3, which translates to 124.7 MJ/gallon. When I taught IC Engines, I asked my students (50) to measure how long it took to fill their gas tank and what volume they put in. The average was 15 gallons in 90s delivery rate. (3/X)

First, I assumed that each station had 6 gas pumps. I've seen everything from 2 pumps to ~60 pumps (Buccee's in TX) - but this is adjustable in my sheet. Then, I calculated the number of seconds in a year and assumed that each pump was in use for 10% time overall. (2/X)

Today, I got DOE Fact of the Week #1114 (I love these emails). It said there are 142,000 public gas stations in the United States. That made me wonder what kind of power supply it would take to replace all of these to power electric vehicles..... so I did the math. (1/X)

When the solid chemicals in an energetic device break down, their size and shape changes. Using neutron imaging during long-term viability testing, NDT professionals can see warning signs such as cracks or bubbles in the materials.http://bit.ly/2BQY9qI
