ARRL FIeld Day 2021 in Village Park

 2021 was my first ARRL Field Day.  I set up in the greenbelt in Village Park.  There was a table for my gear and some nearby trees to string up my antenna.  I used a 40m dipole and a multi band Wolf River vertical coil.  Using a battery and transmitting at 100W, I was able to hear most of the Western US but was only to make contacts in California and Nevada.  Looks like I need to work on transmitting more.

Jaya - UCSD Class of 2021

Jaya finally graduated with a degree in Chemistry from UCSD.  Graduation ceremonies were restricted so we didn't go.  One kid down, one left to go!

Shooting around Southern California

Sporting clays at Raahauges in Corona.  They have a great set of stations.  Worth the drive!

Trying the new 20 gauge pump action.

Combat Steel at Rainbow range.

Fun combat shoot with Oceanside Pistol at Iron Sights.

Father's Day 2021

Awesome Father's Day weekend as my parents made their first trip to California since moving to Tucson.

Spent Saturday at the Antique Gas and Steam Engine Museum with my dad and my son.  AGSEM is a great place and I am glad they are back in action.

Petting zoo

Flywheel of an engine that used to at the Holly Sugar plant in Santa Ana.

Not too many open spaces left in San Diego.

 On Sunday we went to the range to shoot the Lee Enfield No. 4 and the AR.

Green Power Math

Short and concise assessment of the impossible math of going totally "green" and getting rid of fossil fuels.

When I first read it I was curious about the 1.7 PWh of fossil fuel usage and how the author got that number.  By using the first data source reference, you get the energy consumption of CA in 2019.  Adding the first 7 rows which are the fossil fuels, you get 5.7 trillion BTU's.  Converting that to Wh gives you 1.7 PWh.
Note that motor fuel accounts for 1.7 trillion BTU's.  So just replacing all cars and trucks would need 30% of the added power generation.  I.e. one nuclear plant every 9 weeks from now until 2030.  Sounds doable.
