    real world EVs review

    So.... really no good reason to build more ICE? We have cars now that do everything you're describing. I'm sure people in the other 48 states would like to continue to have the ability to insure their homes against 'natural' disasters. Clearly we can't have both. Which desire should have...

    real world EVs review

    Did I not say 'vehicle sales' not all vehicles? Yeah. Existing ICE is going to be around for a few decades. But even the ~291M number is misleading. The more important number is passenger miles. How many of those 291M are weekend cars? 2nd cars? Old trucks that run to the dump once a week...

    Did you catch the 'sequel'? ;) "South Park" apologizes to Al Gore and admits it was wrong about global warming

    ... so why aren't you applying that knowledge to EVs? 918k EVs were sold in the US in 2022. That number is doubling every ~3.5 years. How many years until it reaches 50% of vehicle sales? That's how the math generally works. ~10% => 50% takes as much time as 50% to ~100%. Do the math...

    If 'math' is 'religion'.... doesn't that render each word meaningless? :unsure: War is peace, freedom is slavery and ignorance is strength too? :rolleyes:

    real world EVs review

    Allow me to introduce you to this amazing mathematic feature known as 'exponential growth' :) Why build new cars that can't take advantage of this bonanza of clean and often free energy? Why increase the investment needed for grid storage? And another feature of economics just as...

    Cool; Why not pause new ICE manufacturing at least until >50% of jet fuel is biofuel. Would that be fair?

    how come the answer isn't to just use the incredible abundance of energy we're flooded with? Conservation with no deprivation :cool: Win-Win

    real world EVs review

    How would you describe curtailment? If you're unable to move demand to when it's produced it's gone. EVs are one of the best ways to do this. Economically it's even better than free. The marginal price can be less than $0. The causes and effects of negative power prices Understanding...

    An mid-sized sedan BEV like the model 3 gets ~130mpg. That's ~260wh/mi. Even if you optimistically assume ~50mpg for a TDI that's ~820wh/mi. That's 68.3% less. Hence ~70%. For the ~5th time. You have to look at the net effect. If taking 10kWh from the grid means 10# of coal is being...

    That's not the point. Look at where H2FC cars are positioned. They're also in the 'uncompetitive' category and it's physically impossible for efuel to be more efficient than H2FC. What sense does it make to invest CAPEX in a facility to convert H2 into a liquid fuel when you can sell it into...

    The average market price of the feedstock. Hydrogen. You'd need ~2 kg of H2 to make a gallon of ediesel. The cost per kg is >$5. That's not counting the cost to actually refine it... What exactly is the point of this given that the Hydrogen ladder is a thing? What sense does it make to...

    Why would we spend >$10 for a gallon of ediesel when we could just make cheaper fertilizer from H2? The Hydrogen ladder exists for a reason. The net effect is you're just converting methane into diesel. With HIGHER emissions than if you were simply refining oil into diesel. Like I said...

    A gallon of diesel has ~13kg of emissions. What ICE-d is getting ~1000 miles per gallon? 50 mpg is ~270 g/km. Maintenance is ~4x more energy intensive than fuel? .... how?

    Exxon Predicted Global Warming

    How many clinical trials do you suppose backed up the concept of blood letting? Do you think it's remotely accurate to compare modern science with a standardized peer review process to a time when ~everything was driven by anecdote? The longer a theory survives the peer review process the...

    real world EVs review

    Not given the fact that it's physically impossible to meet current the demand for petrol with biofuels. Hence; Not when you look at the ACTUAL net effect. If people are going to insist on examining the 'life cycle' cost of EVs, Solar and Wind (which they are correct to do so) then also...

    What math was used to arrive at 98g eCO2/km? Norway averages ~25g eCO2 /kWh. An EV gets ~4 km/kWh. That's ~7 g/km. Even manufacturing isn't going to add >50. Where's the other ~half coming from? That wasn't the most favorable. That was the LEAST favorable. Even an EV powered from 100%...

    .... why not look at the numbers? I've got ~240,000 miles on my EV with the original battery. Let's assume it dies tomorrow. The embedded emissions are ~10,000kg. That's 42g/mile. Sure, double that to account for recycling cost to be conservative. 84g/mile. EVs don't use grid mix but...

    In the context of the joke I had ~2% invested in TSLA in 2010. So maybe he actually IS in 2010 and that's why the stock did so well? Time travel is real?! :eek: That would explain the comments... :unsure: .... what year is it where (when?) you are? It's 2023 here. I invested in TSLA in...

    real world EVs review

    True or False; Burning a gallon of ethanol means there exists one less gallon of ethanol. True or False; One less gallon of ethanol means there is one less gallon of ethanol to displace a gallon of oil being burned. So explain how burning a gallon of ethanol instead of burning no gallons of...
