I believe the elephant in the room is natural immunity. I'm not a doctor but I believe that the current vaccines work by attacking a specific "spike protien" on the virus which if I recall is made up of 29-32 spikes. That vaccine is most effective on that particular spike and marginally on other spikes. It's effectiveness in doing so diminishes over time which is why booster shots are required to restore effectiveness. The difference between the current variants is that a different spike is active and the vaccines were not developed to attack that spike which is why different vaccines have to be developed to most effective against that variant just like annual flu vaccines are developed to be effective to most recent variants of the flu virus.

When a person contracts the Covid virus, their immune system produce natural antibodies which attack the whole virus (all the protien spikes) and destroy the virus regardless of which variant is present. Further, your body produces these antibodies in the bone marrow which is part of a natural process and continues on into the indefinite future. That means not only are you immune now but always so are not succeptible to new strains. Like I said, I'm not a doctor but that is my understanding how this works.

Many foreign studies are confirming these results with peer-reviewed studies which show this to be the case. Most notable are the Israeli studies that show that natural immunity is up to 27 times more effective in dealing with Covid than vaccinations. We, in this country, have not seriously considered natural immunity as a viable solution to Covid.

Quite interesting. I'm particularly fond of a technology that I don't think is being used today. Diesel locomotives run on electricity. The diesel engine is simply used to run a generator that creates that electricity that runs the traction motors that turn the wheels. On a similar idea, a small, efficient internal combustion engine could run a generator that recharges the batteries in a car. Thus, providing a large mile/gallon efficiency. Couple that with no lengthy charge times. I'd be interested in seeing something like that developed.
