Harvester generator gas and not diesel

  • From all of us at Scout Motors, welcome to the Scout Community! We created this community to provide Scout vehicle owners, enthusiasts, and curiosity seekers with a place to engage in discussion, suggestions, stories, and connections. Supportive communities are sometimes hard to find, but we're determined to turn this into one.

    Additionally, Scout Motors wants to hear your feedback and speak directly to the rabid community of owners as unique as America. We'll use the Scout Community to deliver news and information on events and launch updates directly to the group. Although the start of production is anticipated in 2026, many new developments and milestones will occur in the interim. We plan to share them with you on this site and look for your feedback and suggestions.

    How will the Scout Community be run? Think of it this way: this place is your favorite local hangout. We want you to enjoy the atmosphere, talk to people who share similar interests, request and receive advice, and generally have an enjoyable time. The Scout Community should be a highlight of your day. We want you to tell stories, share photos, spread your knowledge, and tell us how Scout can deliver great products and experiences. Along the way, Scout Motors will share our journey to production with you.

    Scout is all about respect. We respect our heritage. We respect the land and outdoors. We respect each other. Every person should feel safe, included, and welcomed in the Scout Community. Being kind and courteous to the other forum members is non-negotiable. Friendly debates are welcomed and often produce great outcomes, but we don't want things to get too rowdy. Please take a moment to consider what you post, especially if you think it may insult others. We'll do our best to encourage friendly discourse and to keep the discussions flowing.

    So, welcome to the Scout Community! We encourage you to check back regularly as we plan to engage our members, share teasers, and participate in discussions. The world needs Scouts™. Let's get going.


    We are Scout Motors.
Yes it has. While @THil08 strays on occasion I’ve fairly called him out and even DM him occasionally to compliment his posts and efforts. That’s what is great about spirited debate. I like a lot of his posts and he approaches things with an open mind. That’s what makes this forum awesome! Thanks for noticing though. Seriously!

Reuters ask this very question about 10 months back. There conclusion was, everything considered it takes a typical EV about a year of operation to become "carbon parity" with a gas powered vehicle. However, if the EV draws power from a coal-fired grid this may take up to five years or more. Now if your source of power is from carbon-free hydroelectricity or Solar this period is as short as 6 months.
Isn’t most of the us grid natural gas as far as fossil fuels go? I don’t think there are many people charging solely with solar, given the massive investment needed. Does anyone know where both ev and gas/diesel start in terms of co2 output before you buy it off the lot?

I’ve calculated it with model 3 before and got this for ev vs diesel same miles driven:

$1,332 @ 4.1m/kwh (model 3 dual motor) 3,171 kwh used, 4,039 kwh used (grid) (.33c/kwh) 2,727lbs co2 (3,474 lbs co2 actual)

$1,508 @ 4.09/gal (369 gal/yr @ 35mpg) 7380lbs co2

Edited*

Using those co2 numbers (which are based on Maine’s power grid) ^

A gas/diesel car produces 6 metric tons of co2 to make (13,278 lbs co2)

An ev produces about 11 metric tons of co2 to produce (24,551 lbs of co2)

So it would take about 3 years to offset co2 output vs a diesel vehicle. On a gas vehicle it would probably take 1.5 years to offset the output.

And he is helping keep me on track with my anger management as it relates to certain threads ?

As it turns out In 2024, only ten US states used zero coal to generated electricity. Conversely, the remaining 40 states utilize coal as a component or the primary fuel source for electricity generation. Notably, the coal-dominant states include Wyoming, West Virginia, Kentucky, Indiana, and Missouri. Additionally, a report this month revealed that the combined share of wind and solar power generation in the United States has increased to 22%, representing a 5.4% growth from the previous year.

Good to know. I did those co2 calculations with Maine, which gets a most most of it power from natural gas, hydro and wind power (in that order). Only a small margin comes from solar, which is mind boggling considering how many damn solar fields we have all over the place. I feel like when we talk about solar and wind though that we also should mention the co2 produced to make those specialized materials. Plus wind takes a lot of oil for lubrication. Since some parts can be recycled and some not we also should talk about the waste. I know that the windmills in the ocean UMO actually makes the specialized fiberglass they make the blade from, that is not easily recycled. Those blades are crazy strong too, I’ve watched a test where they were deflected then let go and they just got right back to straight again, pretty incredible.

I couldn’t easily confirm that info, but I expect that whichever 10 states you’re referring to comprise much more than one fifth of the country’s population. The largest state by population has no coal plants, and as of a couple years ago, only got a tiny amount of electricity from a couple coal plants outside the state. It seems that nationwide about 80% of our electricity comes from a combination of natural gas, nuclear, wind, hydro, and solar (https://www.eia.gov/tools/faqs/faq.php?id=427&t=3)

If you would like to confirm my reply or simply look up your state, here is where my information came from.

To add to what's already been stated, if any emissions sensors, DPF, DEF etc. end up needing to be added any cost savings are gone.

I still believe modern diesels can be a great alternative for long distance driving, but they get gummed up quickly for short trips. I had a Discovery 5 Td6 and it was fantastic on cross country trips. When I stopped doing those regularly (kids graduated), I started having all sorts of issues with emissions equipment getting fouled.
 
I do wonder which engine does better after getting dunked underwater (while not running). I've submerged a running diesel truck engine briefly and it was more or less fine. I've had a gas engine get very wet (not from fording), and it took a lot of compressed air, and wd-40 to get that thing back in business. Given the expected location of the harvester, it's definitely getting dunked most times someone climbs out the water/mud after fording something.

It’s gonna be incased and there will be special equipment for air and exhaust systems, and cooling system (most likely connected to the battery cooling)

I imagine that engine cooling will be isolated from battery cooling. An ICE engine will run at like 185f - 200f and a battery should be more like 40f - 110f. I am happy to hear that it will be encased and presumably have an elevated intake and exhaust. This is all good stuff.
