U.S. Navy Seal Rebreather equipment:

With Rebreather equipment underwater there are no bubbles coming up at all so no one knows you are there when traveling underwater. Even the electric motors with propellers that transport Navy Seals underwater are so quiet most people would never hear them or know that they are there. 

begin quotes:

 

Navy SEALs utilize closed-circuit rebreathers, such as the Dräger LAR V (MK 25) and Siel Caimano MK4/SEAL MK1, for stealthy, bubble-free, and long-duration underwater missions. These 100% oxygen or mixed-gas systems recycle exhaled gas through a CO2 scrubber, featuring low magnetic signatures, and compact, ergonomic designs for tactical operations. 

This video explains the basics of how rebreathers work:

• Siel SEAL MK1 PRO: Compact 90-minute oxygen rebreather, 6 kg, suited for boarding and tactical ops.
• Components: Breathing loop, CO2 scrubber (soda lime), oxygen supply system, and counterlung.
• Safety Features: Often equipped with three oxygen sensors for redundancy, with some models allowing for CO2 sensor installation. 

• 
  

Operational Details

• Oxygen Use: 100% oxygen systems are used to avoid detection via bubbles.
• Depth and Time: Siel SEAL MK1 Pro is rated for depths >12 meters (40 fsw).
• Maintenance: Uses consumables like Sofnolime (CO2 absorbent), Tribolube (O2-compatible lubricant), and sanitizers.

It is not technologically feasible to transport Oil Tankers through the Straight of Hormuz under present conditions. Why?

 Iran never used big ships like destroyers or battleships to stop oil tankers before.

What they used before is something the size of Zodiaks that are partly inflatable with machine guns and Scuba divers who attach mines to the sides (underwater) of Oil tankers. So, they don't need destroyers to do this just Zodiaks with Scuba divers and that's all. Maybe they would need electric underwater machines to transport the scuba divers long distance to the Oil Tankers or aircraft carriers but that is all they would need to stop Oil Traffic of 20% of the oil that travels all over the world. And people wouldn't necessarily know that anyone was under the water there because it would be so quiet and they could use re-breathers so there wouldn't be any bubbles showing coming up from Scuba Tanks.

NOTE: I got my Scuba diving license when I was between 12 and 14 years old in Southern California and I have been down about 50 feet underwater off of Catalina Island in I think it's called Emerald Cove where I went down the anchor chain and the dive ship looked like it was sitting on top of a telephone pole or something like this in the very clear water there that day. end note. 

So, I know a lot about Scuba Stuff having done that a lot then and I still snorkel with a mask and snorkel in Hawaii every time I go there to this day even though I'm now in my late 70s. We go often to Hawaii about once every year or two now and often stay there on two or more different islands for 2 to 3 weeks time. 

Also, the metal sides of an oil tanker are usually about 1 inch to 1 1/2 inches thick metal and an aircraft carrier is about 4 inches thick of metal. So, an oil tanker can blow up and sink pretty easily but an aircraft carrier doesn't.

Also, if the Iranians sank a nuclear powered Aircraft carrier (and they all are nuclear now from the U.S.) they would create a permanent radiation zone that could make living anywhere near this wreck uninhabitable for thousands of years. So, this might make people have to move 300 to 500 miles away not to die of radiation poisoning for the next 1000 years of more. 

 

So, how to survive all these changes to gas prices which will likely affect the cost of everything you buy including food

Why? Because food has to be hauled from where it is grown to where you live. So, unless you are going to a farm to buy your food direct from the farmer you are going to pay higher prices for everything because of the gas or diesel it took to get it to you. So, the cost of everything including food and everything else shipped to you is going to be more regarding growing the food, hauling the food to you, the electricity is going to cost more because of higher Natural Gas prices and the gas you put in your car is going to cost more. So, literally everything you buy or consume is going to cost more than it did before (possibly by a lot more) during these times.

What can be done to change all this?

This is the question the whole world is asking right now.

But, in the meantime (possibly for the next year or more gas prices and diesel prices will likely double or more during the next year or so. 

So, having a solar array on your roof and maybe an electric car like a Tesla Model X which is supposed to pay for itself within 5 years (at least in California) where energy prices are so high because of gas taxes which repair all our roads is a given.

So, if you have your own solar power that you charge your electric car up with then the gas prices are completely meaningless to you ongoing.

However, then you have to wait to charge your vehicles and hour or more before you can use them too to charge up your batteries to use your electric vehicle unless you own a hybrid which still burns gas.

However, unless you live somewhere like California that has electric charging stations all over the place now you might want a hybrid so you can actually drive where you want to here in the U.S. without charging problems (unless you are going to carry your own generator to recharge your vehicle along with.you. 

 

 

 

 

 

 

Presently Gas prices are 70 cents more per gallon of regular gas in California (or 7 dollars more per 10 gallons) on average for the whole state

I have also heard of one driver coming from San Diego to Los Angeles paying  1 dollar more per gallon of Regular Gas too and this is right now.

This is the worst problem with Gas Prices (potentially) right now in the history of Gas prices ever. And it looks to be getting worse every day. Also, prices go up quickly but don't come down as quickly because of a variety of factors. 

For example, once a gas dealership pays for it's gas it must pass on the higher costs to it's customers even if this is weeks or months later if this business doesn't do a lot of business. So, theoretically a gas dealership (gas station) could be keeping their prices high for weeks or months after the cost of price of Gas to them goes down. So, anyone locally in that area is going to feel the burn for months potentially in their pocketbook. 

begin quote:

As of early March 2026, U.S. gas prices are experiencing a sharp, rapid increase driven by the

conflict between the United States, Israel, and Iran, which has disrupted oil supplies through the Strait of Hormuz. The crisis has caused oil prices to surge above $100 a barrel for the first time since 2022. 

Here are the key details regarding the current, unfolding gas price situation:

• Rapid Price Spikes: The national average for a gallon of gas jumped significantly in the first week of March 2026, with some areas seeing increases of over 10-15% in just a few days.
• Major Disruption: Analysts describe this as a major oil disruption, with shipping through the crucial Strait of Hormuz stalling, impacting global supplies.
• Regional Variations: While the national average has risen, specific areas are seeing much higher prices. California has reported prices reaching up to $5.20 per gallon in some locations.
• "Biggest Surge" in Decades: The sudden rise in pump prices has been described as the largest overnight spike since Hurricane Katrina in 2005.
• Market Impact: The conflict has forced oil prices to soar beyond $100 per barrel, with some projections suggesting they could go higher.
• Seasonal Factors: The geopolitical shock is occurring simultaneously with the yearly switch to more expensive summer-blend gasoline, compounding the price increases. 

• 
  

Contextual Historical Comparison:
While current prices are causing significant pain at the pump, they are still below the all-time, nominal national average high of over $5.00 per gallon reached in June 2022, which was driven by the Russia-Ukraine war. However, the speed of the 2026 increase is particularly severe.
