A Full Tank Running on Empty

-

An electric car weighs the same whether the battery is fully charged or empty. Or, is it heavier when it is fully charged and lighter when there's no charge?  An internal combustion car is heavier when the tank is full and lighter when the tank is empty.  Does that mean the traditional ICE car is more efficient when the tank is less full because it's hauling around less weight?  Or is energy invisible in an electric car?  It must be because all the green new deal and electric car fanatics seem to think all you have to do is plug an electric car into the wall and viola, it's got a full tank of gas.  Too bad they don't understand the dominant resources used to make electricity.  Burning coal and natural gas.  Electric cars really aren't any better for the environment - they just displace the carbon footprint to where it can't be seen.  Out of sight.  Out of mind.

Why are electric cars so expensive?  It's really just a chassis with an electric motor, a switch, a rheostat and a battery.  Plus the typical hydraulics, creature comforts and safety gear.  Shouldn't they be cheaper?

Here's some food for thought.  Why aren't autonomous cars driven by drone pilots?  There wouldn't be near as many accidents caused by the limitations of technology.  People don't want to drive.  Hire someone to do it for you without having them share your space.  In America, the interior of the car is a sanctuary.

I shoulda been a mechanic

-
I often say I should have been a mechanic or a carpenter.  Probably mechanic.  Our front door lock mechanism has been acting up.  It has a typical entry from the front where you push down with your thumb to turn the cylinder to open the door.  The back of the door door knob fell off because it had gotten loose and stripped out the holes.  Turns it out it was much more than that - I had to figure out how to get the entire front pull door handle off to fix it because the latch mechanism fell apart.  I learned this after replacing the door knob and it was still not working properly.  I figured out how to get the pull door handle off and it hit the ground and fell apart into like a dozen different pieces.  I had never seen the mechanism together....  with some trial and error I figured out how it works and was able to time the mechanism and put it back together.  I rebuilt it!!  All the plates, gears, levers, pins, springs and gears. ...

My Mom Died

-
On Monday my mom proclaimed the promise of her baptism. After years of suffering from dementia, she was restored; made whole on the other side. One thing you may not know about my mom is she was tough as nails while having the grace of an angel. She carried my dad through some medical scares and was a huge advocate to him getting the care he needed with her medical background as a registered nurse. Roughly 10 years ago I was charged with taking mom back to Pennsylvania to see her dad, my pappy when he moved into a nursing home. We went to his house and there had been some changes to the back porch. It was my job to take care of mom. I saw my uncle and leapt up onto the raised porch. There used to be a railing around the porch. Mom tried to do the same and tripped on the ledge letting out a yell. Her leg got pretty torn up and was bleeding pretty bad. We got her into the house and decided she needed to go to the hospital. Mom never flinched or complained about the situati...

I've seen things

-
The last couple days of my mom's life...  don't quite know what to say about them.  I remember last Sunday when I came to her house and saw her slumped in the chair barely able to move after the medication fell out of her mouth and onto her shirt.  No one was available to change her shirt.  I asked my Dad if he would do it and he declined.  I did it.  It was the most awkward thing.  I had her told the clean shirt up to cover herself as I carefully removed the dirty shirt.  I planted by eyes next to her head looking at the back to her chair and was able to help my Mom be comfortable while preserving her dignity.  There are some things about your parents that you shouldn't know.  Like what an 80 year old body looks like while deprived of nutrients and exercise....  So there was that. Then seeing my Mom in the hospital bed after she could no longer walk.  Laying there with her head cocked to the side and her mouth open as dying pr...
