TheGerm24 : That 23% of GHG emissions can't be correct. Maybe 23% of GHG emissions from the transportation sector but not from the entire economy. This source says total transportation is only 27% of US emissions. Obviously trucking isn't 80% of all transportation.

Jake Voorhees : That's always why I love Elon Musk :) innovation after innovation after innovation. Thanks for another great video!

Nohara Loco : As a professional truck driver I would like to weigh in on this topic. First the simple and most basic fact of the trucking industry is that it is subject to the economy and market, not a guider of it. The reason alternatives have not been implemented is due primarily to cost. NOT cost to the trucker, rather cost to the CONSUMER. The industry is a reaction to the needs of economy and as such all shipping is done in the most cost effective means. At their current level of technology alternative energy and renewable energy trucks simply aren't viable to any shipping company. The decrease in capability and increase in cost, support, and manpower is overwhelmingly against its adoption. Not because trucking companies are greedy, but because consumers are unwilling to pay for the increased costs involved. An increase in the cost to move a product means there is an increase cost charged to shippers, which leads to an increased cost in the base product, and that means an increased cost to the consumer. Many will say "truckers should just charge less" which I have heard. Well how would you like to spend all your time working away from family and friends, sleeping and living in an area the size of a closet, and still lose money or at best break even? I doubt anyone actually would as it is asinine. To put it in comparison, work their normal job for 70 hours a week, and not get paid. No one in their right mind will do that. Its simply idiotic to think otherwise. Now that being said I am actually quite interested in new more clean and efficient technologies. I am hoping a company develops an electric or at least hybrid truck to replace diesels. The technology is a long way off yet, to put it strait an electric truck would need to attain the same range and hauling capacity while also being cheaper to operate and maintain. Because there are already major changes in trucking on the horizon. The federal government mandated epa and mpg ratings for commercial vehicles that take effect in 2 years means that there is already a major jump in efficiency. Companies have already developed trucks that meet or exceed these needs while not being more expensive than current designs. And with fuel costs continuing to rise the industry is already demanding even better mpg from their fleets. Especially owner/operators who foot that mo ey themselves. The short of it is, unless Musk can pull the technology to be cheaper, more efficient (cause changing your fuel costs to electricity costs wont change a thing or incentiviz anyone. ) And with equal or greater range, it is extremely far from replacing or even supplementing current trucks. Also dont forget cost to maintain, anyone who has had to repair an EV knows how bad that is, imagine on a massive scale with vehicles that regularly put 250,000 or more miles in a single year. It is simply not feasible at this time. Being real with you all.

Tuna Sandwiches : Reminds me of a Chevy Lumina minivan from the ‘90s...

Shift N Drift : 1:58 that's absolute rubbish mate. Think about how many times your stuck behind a truck at the lights because they accelerate so slow. With Tesla's fast acceleration truck drives will not hold up traffic anymore.

Arnav Aggarwal : Real engineering man you are awesome.....

billdale1 : Thanl you for doing your best to give a balanced, unbiased look at the Tesla Semi. There is a terribly trollish Aussie that did something similar except he severely cherry-picked the data he used--- resulting in nothing more than a blatantly anti-Tesla, anti-Musk rant. I personally think the Tesla Semi will have a slightly limited practicality until greater energy density can be brought into the equation, but for the applications for which it is currently (no pun intended) a good fit, this Truck will give us enormous benefit. Vive la Musk.

Tyler Hardy : Electric motors*


voicetube : That was damn thorough! Love when somebody puts the sort of thought into the actual metrics, etc. Ultimately though, I think that it will win. On that note, one factor that can't, I think, really be easily calculated here is potential improvement in battery technology over the very short term… And possibly sooner than the calculations here predict. Lastly a totally silly comment that some people may not like - although it would have been very cool and somewhat hilarious is, at the very end of the video for the narrator to say, "And remember… Lucky Charms… are magically delicious!!" Now come to think of it, however, I think that that particular metric would have reduced the funding to the dude's Patreon page, which could've been reason enough to not add that extra line at the end (although I would've had a good laugh and a smile, if he had).

Enrico D'Urso : where is the tool to try to enjoy the configutarion of tesla truck?

Dominic Ofa : Bunch of garbage here

shashank Reddy : I wrote that equation 😂😂

Sean O : Yeah and Space X will never get off the ground.....oh yeah, rt.

Reese Garcia : Do you really think electric cars are green and help the environment? Because ur wrong. Where does that electricity come from? Coal burning, fossil fuel burning, and yes ur about to say "solar panels" well ur wrong again, the making of solar panels is terrible for the environment, also the making of all the plastic parts in all cars and also the batteries for the electric cars are just as bad, unfortunately there isn't really an escape from pollution and global warming, we need transportation and no matter how we get around, the making of all transportation vehicles and most products will be the demise of humanity as we know it.

U B : People don’t understand the repair cost on electric motors. No trans no engine. Electric motors will last millions of miles

Scott Haddock : The truth about the tesla truck is it can't roll coal

Jeremy McReynolds : The biggest flaw in your case is you are making serious assumptions about Tesla's battery density. You do know they make their own batteries right? You do know we're basically in a little known, proxy arms race with China in regards to battery production and density right? Sony, Panasonic and IBM didnt invested billions in the gigafactory for shits and giggles. While there is alot that isn't proprietary that others simply copy, hell you should know Tesla openly shares improvements for other to improve upon and monetize, the idea that they likely haven't made some significant improvements and solid projections and kept them under wraps, is frankly, naive. I'm very skeptical of this endeavour of Teslas but frankly this case really doesn't push me one way of the other.

Prop City : Go Tesla! Go ELON!

Jacxel : If we assume the tesla truck is not marketed at companies hauling sand/rock/concrete/liquids how much of a concern is the weight limit? I don't know the figures but surely companies like walmart who have supposedly pre-ordered a number of these trucks would not approach those kinds of weights in their average loads?

whutman : "There really isn't any proprietary technology in a tesla" from 2:44 --- are you kidding me? Did you do zero research? The whole "secret sauce" behind the gigafactory is "proprietary manufacturing techniques" that Panasonic and Tesla have mentioned *OVER* and *OVER* again on earnings conference calls for the past, what.. 2-3 years?

bzdtemp : Simply comparing the energy vs, weight of the batteries vs a tank of diesel is much to simplistic. A conventional combustion engine and it's support system ie. fuel system, gearbox and so on not only is heavy and bulky compared to the electric alternative it is also wasteful. This means less than half of the energy of the diesel fuel will turn into movement of the truck, so while the energy density is still much high than the batteries the Wh/Kg comparison shown is not really meaningful outside a lab.

Better With Rum : you're very one dimensional. consider that Elon did not share additional information for competitive business reasons or that Tesla often invites the world to participate in the goals, dreams and values he has. Stop being so nagitive.

chimp3376 : You really should look to support your YouTube follower more. If we are not valued please can you remove the adverts from our view.

Colt Kuhn : And why didn't they just use hydrogen for the Semi Trucks? Lower cost, less weight and less of a headache with production? From a whole business standpoint, if they can get these to sell, which is iffy, producing the vastly higher volume of batteries required for these trucks will drop all their battery production costs. Also, Elon doesn't like hydrogen for some reason. Which is sad because it has a lot of potential and makes a much simpler build process.

krazyhartin : I can't help but I need to correct you. It's called "electric motors" not "electric engines" please research these two words if you think I'm being a dick. Just incase you make this other mistake that Youtubers make, it's "miles/kilometres per charge" not "miles per gallon" it doesn't have a tank filled with liquid electricity. Also, please indicate both types of measurements when you're speaking in metric or imperial and not throw the two in together. Thank you.

Hannes D'hondt : Why are American trucks only allowed 36 tonnes? Here in Belgium it's 44.5 tonnes and generally our roads are less wide than American roads (because they're older), they have less lanes, and the country is more cramped. The Netherlands is even more dense and there it is 50 tonnes. Australia is like America in a lot of ways (big roads, a frontier, low population density, young country) and they have those massive road trains chugging about.

Youbatfalcontube : Suppose that ALL the trucks in US were like this one. Calculate the energy that MUST be generated in power plants in order to charge ALL these billions of batteries and THEN tell us how the emissions will or can be reduced. They will just change position. It is IMPOSSIBLE to produce that much energy from solar panels or water movement.

Cormac Green : Real Engineering = ♥️

Kloko Loko : Battery calculator is FALSE, present battery like 125wh/kg- just put on - Energy Density (Wh/kg) - for example number 1000 and you will see that 1000kwh battery weight 2 tons instead 1ton !!!!

Kloko Loko : WHAT a f... is "fburden, packing burden factor.* " for 0.1 factor battery is 1000kg and for 1.0 factor is 100kg !!!

Kenjinn : PepsiCo has already pre-ordered 100 trucks for its fleet.

Roy Thompson : I think it is very respectable that you admit the flaw in your initial opinion. This sets you bounds ahead of other channels, and is a very commendable action towards achieving your vision of being the best science documentary channel on YouTube. Keep up the great work!

Corbin mcmullin_mtb : Will they ever make an electric truck to replace logging specailized tractor trailers?

Steve Tice : Nice, small nit pik - not "electric engines", rather "electric motors"

Rishabh Bhati : so isn't it possible that you created this video to create fund for your channel by makeing controversial statment on tesla.😀

Stark Munro : So what about Nicola one truck? Wouldn’t that one make more sense?

Toy Teardown : Does the calculation take into consideration regenerative braking? Having a lower drag coefficient of a Bugatti isn't a benchmark. Bugatti's are designed to keep cool not be slippery.

Marcos Noble : How can an enginneer like you keep shilling for renewable energy. Go research nuclear.

dojohansen123 : Overall a great video. But I do think you are significantly overestimating the battery cost and underestimating the gravimetric energy density. It would be interesting to see a more thorough analysis of the business side, but it's understandable you aren't going deeply into it (this is an engineering channel after all). A truck is not *always* running at maximum weight, and depending on the cargo, it is possible to be volume-limited rather than weight-limited. I also think you significantly overestimate both the cost and weight of the battery pack. You even alluded to it yourself with a short mention of solid-state batteries.

Van Sohren : Didnt they say making these batteries are so bad for the enviorment it doesnt make much of a difference?

Alfred Chiu : There is a lot of concern over "range" but obviously no one has been stuck in traffic for hours and hours of stop and go traffic; often caused by truck accidents. My Sierra 1500 pick-up, which is capable of over 23 mpg at 60 mph, can not even make 18 mpg with a lot of coasting and slow acceleration. Needless to say, the range falls off the cliff. The electric semi with regenerative braking and autonomous pilot will increase fuel efficiency and keep the truck out of trouble. The future is coming.

MrYlijumala : Real Engineering that is such a good point on making the world better. I hear so much about "how much prius car cost to make is using resources more than normal petrol engine car would" but there is a time when someone has to pay for sake of making those future cars and tech. They wont pop out of thin air. Elon is on next level on this and does not care about bankruptcy since he has enough money to make himself a living. He does not need all the goddamn money in the world like some oil companys etc does.

Kenny Lee : 2:25 80% of Routes Less than 250 miles. So it only works in local routes and the down time for charging and range still is a deal breaker.There is no way this can replace diesel truck entirely. Perhaps a separated Etrailer will solve the problem for the time being.

Amy Olsen : Tons and Kg are not the same.. huh? 1:27 What am I missing? 1000kg is called a ton. I saw later in the video.

Finn Siemetzki : I love the combination of a extremely well made video and an awesome accent.

Joe Zip : Where are You plugging in in 8 hrs. to charge - Hoover Dam? What does the thing weigh EMPTY? Geeze in lbs. U.S. POUNDS still no answer. Payload can be no less than 48,000 lbs. (should be 52,000). Regenative Braking is a joke 1/2 hr down Eisenhower would not light the dashboard. answer: Produce goods Locally and REDUCE the NEED for TRANSPORT.

Red Viper : So it's the laws that need to catch up then.

The 1980s was the best period ever! : I never knew an Irish person could be so intelligent.....
