Prius. Easy 50mpg. We just drove across the US twice, some states with 80mph speed limits and wind. Average overall? 51.6 mpg. #prius
Discussion
Gas mileage is so good in these cars
…..and using conventional readily available fuels, no infrastructure or running around looking for a charger. I do wish they were diesel, we would get 70-80 mpg easily if they were.
Hydrogen is coming nationwide.
You can already get the mods or diy it.
There’s also 4wd add ons if it’s a newer model year.
This is the thing about hydrogen….storage is difficult, range is difficult, and hydrocarbons are hydrogen energy, stored in the best way. Renewable fuels are the best solution, we just need to stop digging them out of the ground and synthesize them with real time energy. Climate “crisis” solved with no new infrastructure required. Closed carbon cycle. The whole planet is solar energy, fossil fuels are just solar energy from 250 million years ago. #renewablefuels #energy #climatechange
Um I think you need to do more research.
I’m taking about on demand hydrogen fuel production with water.
1 gallon of distilled water gets ~400mpg.
It’s safe as there is no storage of the gas as it’s produced on demand.
Can be diy with 2 mason jars & simple parts.
Via Electrolysis or Steam Reforming? I am highly skeptical your 1 gallon input for 400 miles output in any production vehicle
Electrolysis & we are talking Prius cars
So, as a person who has used electrolysis to produce hydrogen, I can tell you that DYI units are typically low temperature and pressure, and that means really low energy conversion efficiency. If you are referring to these YT “hydroxy” production rigs, that is not only exceptionally dangerous, but ineffective at fueling any real power producing engine or fuel cell. We can review the chemistry and math involved if you wish, but hydrocarbons or anhydrous ammonia are much more dense methods to store hydrogen energy.
IMO hybrid makes sense, especially combined with a supercap that can give you 2 minutes of V8 power for a car that normally is a straight six. The lithium you can keep thx. It's never gonna be as stable as carbon, or as resistant run-away self-oxidation. idgaf about that it's 5x as heavy it's 10x as durable and safe.
💯 hybrid Atkinson cycle diesel on renewable hydrocarbons with SCR is as good as it gets IMO. Super capacitors are actually pretty light weight too comparably.
There was also the Honda Civic VX that got some pretty insane fuel economy just off petro, about 45mpg.
Question: have you have any luck with carb-mods?
There is some complexity when engine efficiency is being considered. Gasoline engines suffer from volumetric inefficiency, that is to say that for spark ignition to happen the air and fuel has to be in the correct stoichiometric ratio for the full volume of the cylinder. If a carburetor modification moves the ratio outside of the flammability range the engine won’t run. Diesel engines are the most thermodynamically efficient internal combustion engines in widespread use because they draw in air alone and inject only the fuel required to produce the requested power, no volumetric inefficiency. The Prius uses an Atkinson cycle gasoline engine that increases efficiency by elongating the piston stroke to fully utilize combustion pressure at the cost of power to weight ratio, still an equivalent displacement turbo diesel would be much more efficient.
That's a good rundown, thank you.
The Honda Civic VX from 92-95 introduced a type of valve lifting that created a vortex with the air and fuel as it entered the combustion chamber. They explained that it was a clever way to achieve more efficient fuel atomization. I remember a mention of the droplet particle size; the smaller, the more complete fuel burnoff.
Quick question: what kind of diesel van would you say is the most efficient and reliable?
Regarding the diesel van, what country are you considering?
USA.
This is complex because of US emissions law. The big three use truck engines in their vans. This is not ideal because of the large displacement, unnecessary unless towing heavy trailers. The import options are technically ideal, but parts and service can be an issue. I would choose the Mercedes sprinter, parts are expensive but available, rarely needed. A 2006 or older Duramax from GMC can achieve 20 mpg and offer incredible durability. I’d avoid Cummins or the Ford Navistar engines unless you’re considering a 7.3 or a 12V Cummins.
That's a good run-down, thanks for the info!
