Some electrical clarification

Over the past several months, a local writer has shared some more or less dubious opinions about electrical supply grids, in general, and electrical vehicles (EVs), in particular. I’d like to counter some of this with my experiences.

My EV has a 75 kWh battery (energy equivalent of two gallons of gasoline), which provides a real-world range of over 300 miles. A comparable performing gasoline car (0-60 in 5.0 seconds, top speed 140 MPH) would cost about $16 to travel 100 miles (25 MPG at $4 per gallon). My cost is no more than $7 for the same distance (25 kWh at $0.28 per kWh at public 480V DC high-speed charging stations, less expensive for slower home charging).

I typically recharge in my garage using 48A at 240V AC, or about the same power consumption as two central air conditioners (common for larger Antelope Valley houses). This 11.5 kW adds 45 miles of range per hour to my car and is at the high end of what EV manufacturers provide for home use today. Higher amperage options available earlier were discontinued due to low demand for faster charging at home. For home charging, there is no predicted demand for power above 240V because EV owners routinely recharge relatively slowly over time, often overnight when electrical demand is lower.

While the electrical grid will indeed require more capacity over time due to increasing EV and other electrical demands, there is no need for an immediate grid reconfiguration driven solely by EV usage.

They’re all geniuses

How is it possible that a whopping 735 Antelope Valley High School students can get a grade point average of 4.0 or better, as reported in the AV Press dated April 17.

I graduated from high school back in the 60s and only a handful of students in my entire senior class of 928 pulled down straight A grades.

Kids are being given A grades by generous teachers who probably think they are helping students by inflating their grades and improving their self esteem. Actually, they are doing them a disservice. What happens when these A students get out of school and lack those academic skills needed to succeed in the real world?

California is 10th from the bottom of states having the worst academic scores in the country. Our liberal education system wants to look good in the public eye by puffing up these kids egos with super grades and high graduation requirement rates.

Teachers with high standards, have a relevant curriculum and dole out  grades that students actually deserve. The are often criticized as being bad teachers because they are strict and don’t give out A grades willy nilly. Unfortunately, these teachers are slowly disappearing from our schools.

I’d like to believe that these students are worthy of their A grades, but when schools in California have low academic standards, I can see why so many kids are getting these inflated grades.

Fix the

 potholes already

State Highway 138 west of Highway 14 is falling apart. Huge chunks of asphalt are missing. They are so bad people are driving on the wrong side of the road to miss them.

All the state has done on that road for the last 20 years is halfway patches, slurry coats and 2-inch caps. Over the full length from the 14 to the I-5, not a single pothole has been patched. At the dangerous 90th Street West intersection, drivers have to drive around the potholes in 138 to get across it, adding to the danger of the crossing.

I am not advocating a complete reconstruct, just patch the potholes before someone gets killed dodging them.

There must be

 a better place

Sprouts will be a welcome addition to our valley. The fly in the ointment is that it will be within two miles of other small specialty grocery stores.

Traffic congestion around the mall is already irritating. Poor initial planning now has emergency vehicles, 18-wheelers, buses, delivery vans, RVs and cars backed up or at a standstill. Broad avenues and truck beltways should have been factored in at the start.

Will the proposed condos and apartments meet the needs of current residents or bring in an influx of new folks to further overtax our infrastructures?

How about a Sprouts off Elizabeth Lake Road at Ranch Center Drive or Avenue O at Seventh Street West or between Division Street and Sierra Highway off Rancho Vista?

South or East of Anaverde development by West Avenue S is unincorporated land just waiting for a classy complex. A Sprouts next to middle-class  homes for the valley’s retired seniors would be ideal.

Imagine a walkable community!
