I think my next car will be an electric car. We can't keep burning fossil fuels. My brother has one of those BMW electric hybrids with a motorcycle engine and he claims his gas is six months old in that thing.

BMW PHEV's supposedly have some venting/pressurization to prevent 02 in the air from getting to the gas and causing it to go bad, but I duh know...

I'd use some good ole Sta-Bil with a PHEV.

Transportation is only about 25% of our CO2 emissions.

If/when they get fusion to work, petroleum and natural gas demand will drop off to a trickle. With enough cheap, green electricity, you could make green gasoline from air and water.

I have to make an effort to burn down a tank of gas in 30 days or less to keep it from going stale in the tank. I also run my tanks down to less than one gallon left, to minimize the amount of old gas getting mixed with the new gas.

States and Cities nation wide are banning the use of Natural Gas for new construction and I'm sure that will trickle down to CNG many other uses.

That only reduces CO2 if the electricity replacing it comes from non-combustion sources. Here in Bubba County, electricity comes from burning natural gas.

Generating heat from electricity is very inefficient, because there are huge heat losses at the power generation station.

I moved into a new-construction apartment when I moved here in 1995. The hot water heater was gas, and it also provided heat. There was a water pump and heat exchanger in the AC ducts. The heating system used the AC fan and thermostat.

A lot of commercial refrigeration and air conditioning is done with natural gas through the "absorption cycle." There was a move to make residential systems, but it's not really taken off. Conventional (vapor-compression cycle), electric residential air conditioners have got a lot more efficient in the last few decades.

What would the formulation of this green gas be? Would it not still be used as combustion of hydrocarbons and create CO2?

The process would start by sucking CO2 out of the air, and taking the carbon atoms and mixing then with some hydrogen atoms from water to make some sort of CxHy. When the CxHy is burned, the CO2 goes back into the air. The net CO2 released would be zero, though.

Burning wood is considered zero net CO2 release, long term, since the tree sucked CO2 out of the air when it was growing.

So it burns the same. No different than drilling oil. Only thing is the completely unrelated carbon capture which would be better utilized for making durable goods or some such. No point in going through the process to create recycled gas.

Just like the oil and coal sources did, only longer ago. Unless you believe in abiogenic source of hydrocarbons, like vapor streaming from the mantle - see T. gold.

Yep.

Nobody ever seems to recognize or acknowledge this simple fact. Do some research on the thermal efficiency of conventional fueled power plants.

EV's might make some sense in reducing CO2 emissions if we had large amounts of carbon-free energy readily available.

Longer term, nuclear plants could make this possible but most green people seem to want to banish nuclear.

Right now nuke has at least 2 huge safety issues . Radiation in general - the tech, and terrorists.

I've been inside nuke plants. (work related much clearance RQD ) Emergency exit doors designed in originally are now caged off and you need the right key/authority to even flee. Security says that is so you are trapped and they can shoot you there with their automatic rifles of which there is no short supply.

But that is only last gasp stop gap for an individual that managed to get in. Imagine the other protection issues

How important is the tech thing? We still don't have a repository.

Yet waaaaaaaaaaaaayyyyy back in the day when I was becoming a registered professional hydrogeologist, (among other things ) the book cover looked like this:


Do you recognize that area south of jackass flats?

The more things change the more they stay the same.

This answers my question about big rigs:

Electric Transmission Towers constitute a great threat in security. A coordinated attack on a few strategic transmission towers would take down the grid in a large area and take hrs/days to re-route/restore service. The towers are mostly in isolated/un surveilled easily accessed locations.
The towers depend on the other towers in the line for support due to the weight/tension of the conductors so taking down one tower would cause many more to collapse.
