Lovely when you're outrunning an oncoming hurricane. I bet those storm chaser guys are psyched.Solar panels

That Might be possible for local deliveries with better than current batteries considering that kind of workload.Tesla is reportedly delivering its first semis by the end of the year.
That makes no sense.Lovely when you're outrunning an oncoming hurricane. I bet those storm chaser guys are psyched.
The Tesla Semi allegedly can go 500 highway miles on a charge. The heater claim is false, Bill. Range drops for all vehicles (gas included) in cold weather, and it’s mostly due to factors other than the heater.That Might be possible for local deliveries with better than current batteries considering that kind of workload.
Long haul truckers on the other hand during their 11 hour federally mandated drive time can go 600 - 700 miles. I’ll believe electric long haul when I see it considering current car distance can be cut by up to 40% by simply running their heaters too hot.
You should share your knowledge with Tesla, they seem to be thinking otherwise. See a note from the Model 3 Owners Guide about heat and A/C climate control below-The heater claim is false, Bill. Range drops for all vehicles (gas included) in cold weather.
Environmentalism and sustainability initiatives for companies have made diesel powered engines a thing of the past. Diesel-electric is a great concept, but it’s a non-starter nowadaysI don’t think people forgot… Tesla is reportedly delivering its first semis by the end of the year. I do wonder though why diesel-electric hybrids aren’t a thing like they are in trains. Any mechanical engineers out there able to chime in?
You need sunshine for a solar panel to work. In a cloudy climate, no bueno. And if you're trying to outrun a storm with a limited charge (think Florida), you're screwed.That makes no sense.

That refers to the heater use only. ICE mileage efficiency drops by about 20% in cold weather. I don’t know why you are implying this exclusively happens to EVs.You should share your knowledge with Tesla, they seem to be thinking otherwise. See a note from the Model 3 Owners Guide about heat and A/C climate control below-
[Note
The climate control system is powered by the high voltage Battery. Therefore, prolonged use decreases driving range.]
A/C systems in ICE cars do decrease mpg slightly in warm weather months, as the compressor is an extra drag on the motor. ICE Heaters do Not reduce mileage, they’re usually heated by redirecting already hot engine coolant to the heater core …
Germany is a world leader in solar use. Not the sunniest climate…You need sunshine for a solar panel to work. In a cloudy climate, no bueno.
@lost_blackbird Germany is significantly sunnier than the UK?it's simply not sunny and hot enough for prolonged periods to justify the expense of
an installation of such a system. I'm sure they are useful in some countries though.
I have a lifetime of working on my own vehicles, Learn the facts:ICE mileage efficiency drops by about 20% in cold weather. I don’t know why you are implying this exclusively happens to EVs.
ICEs are less fuel efficient in the winter. Winter weather is bad all around for fluid mechanics. Drag, viscosity of lubricants, and the fact that your engine takes at least 5 minutes to reach normal operating temperatures. You can pretend winter mileage loss only occurs in EVs and not ICEs, but that just isn’t the reality.Learn the facts,
Due to the fact that cold air is denser than warm air, there are significantly more oxygen molecules entering the combustion chamber when it is cold outside than when it is hot outside. Better combustion is made possible by more oxygen, which results in a significant gain in power.
Hence cold air induction kits.Due to the fact that cold air is denser than warm air, there are significantly more oxygen molecules entering the combustion chamber when it is cold outside than when it is hot outside. Better combustion is made possible by more oxygen, which results in a significant gain in power.
This is incorrect. Gas vehicles do not get greater or equal fuel efficiency in cold weather compared to warm weather. The fact that you are even trying to argue this shows how irrational your bias is on this topic.Let me break this down to an elementary level for you,
EV heater runs on battery - battery can’t recharge itself because the technology doesn’t currently economically exist = less battery power and mileage.
ICE heater heats after 3-5 min. driving on already hot engine coolant - blower fan runs on constantly charged by motor vehicle electrical system - motor runs better in cold air = same or better mileage as warm weather driving without a/c on.
Hence cold air induction kits.
Let’s put this entire thing to bed now.Let me break this down to an elementary level for you,
Why is winter fuel economy lower?
Cold weather affects your vehicle in more ways than you might expect:
- Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids.
- It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures.
- Heated seats, window defrosters, and heater fans use additional power.
- Warming up your vehicle before you start your trip lowers your fuel economy—idling gets 0 miles per gallon.
- Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds.
- Tire pressure decreases in colder temperatures, increasing rolling resistance.
- Winter grades of gasoline can have slightly less energy per gallon than summer blends.
- Battery performance decreases in cold weather, making it harder for your alternator to keep your battery charged. This also affects the performance of the regenerative braking system on hybrids, plug-in hybrids, and electric vehicles.
All vehicle types have efficiency reduction in the winter. EV range less in winter is about 2/3 the heater, 1/3 other factors. Gas vehicles experience a 20-30% loss themselves. The argument you made is that only EVs suffer range penalty in the cold, which is false.EV heater runs on battery - battery can’t recharge itself because the technology doesn’t currently economically exist = less battery power and mileage. Possibly up to 41% less mileage.
Bias is natural however there is no need to spread information that is untrue or misleading.I do admit that I am biased towards the vehicles that about 97.8% of the world currently drive and isn’t going to completely end anytime this century. End of my discussion participation …
The problem with the Semis is that they need so much power, not just to haul the truck, trailer, people and batteries, but to haul cargo as well. Are these Tesla trucks going to be able to haul paper? Are the batteries plus cargo going to make them over weight capacity? Sorry, but I honestly don't see it happening.I don’t think people forgot… Tesla is reportedly delivering its first semis by the end of the year. I do wonder though why diesel-electric hybrids aren’t a thing like they are in trains. Any mechanical engineers out there able to chime in?
The truck is rated for 40 tons. Once the vehicle reaches speed it’s a function of drag which on level ground is more about aerodynamics and rolling resistance then weight. What makes you think the engineers haven’t figured this out?The problem with the Semis is that they need so much power, not just to haul the truck, trailer, people and batteries, but to haul cargo as well.
