Pantographs were used in trolleybuses from the early 1900s. Some of the newer Chinese buses have pantographs and high-speed charging at the stops but not between them, allowing them to run continuously. This seems like a more economical route to go. More difficult for trucks which go long distances between scheduled stops. Just having high-speed charging at the local depot would work for local distribution, though, where the vehicles return frequently to restock.

This was tried in the USA port of long beach about 7 years ago. Trucks going from the port to local rail yards had the ability to use over head electric wires for power.

I have a great solution. We can build steel tracks that we can call rails. Then we can put all the containers from the trucks and load them on and run them. We can call these trains.

A mix would be ideal. Electric trucks with the ability to charge directly while driving. So you wouldn't have to be wired every mile of highway. This would optimise the drivers' schedule. Compared to battery swap stations or static charging points, this could cover a larger area for the same amount of money invested. Similar logic to partial trolleybuses, which with smaller batteries will travel longer distances with less stationary charging time than electric buses.

The idea has been around for much, much longer. In the 1960s, for example, there were trolleybuses with overhead lines in many Eastern Bloc countries (in German: "O-Bus", from "O-berleitung"). But this was abolished after a decade of use because other things worked better and cheaper. It is not something new.

As a child in the sixties ((1960-1970) I remember the troleybus system (Public Transport) in the city... a better cheaper and more flexible system then the current tramsystem (expensive fixated railsystem that can get blocked by the slightest trafficproblem) because those buses can drive partially on 'electrified' routes and can switch to 'motor' (gas, H2, benzine, gasoil ...) on the other non-electrified parts. Sort of Hybrid-Public-Transport

Sabine, you're a genius,thank you for making the difficult, easier.❤

Those double patographs look like a short circuit wating to happen. The truck drivers would have to concentrate keeping to the centre, as well as watching the traffice. We used to have trolley busses that had 2 long poles contacting the overhead wires, which were rectangular in cross section and longer downwards for the trolley to slot onto..

Wait, you don't have trolley buses anymore ? After trains and trams (aka also trains) they're the next most carbon-free method of transport. No need of super big, super heavy, impossible to stop burning if it burns battery like electric buses. And because they don't have to carry the battery, they're more efficient too. Well, not a big battery, having one for 20-30 km or so is good to have. In Romania, and from what I know other Eastern European countries, we still have them.

This reminds me of a story told by my grandfather. When he was young he was travelling musician with a vaudeville show and found himself living in Atlanta USA. Being a young musician he didn't have enough money to pay the electric bill he concocted a scheme to get free power. He gung a wire out the window and across the hot wire for the trolley system and got electricity that way. A clear example of a 3D scheme - Daring, Dangerous, Dumb. But he apparently did this for a while without being either caught or killed.

Diesel emits less CO2 than the alternatives - it's not just cheaper. The alternatives, like soy based diesel and palm oil based diesel have to account for CO2 emitted in the process of growing, harvesting, transporting, and processing the crop. Once you do that, they emit more CO2 per unit volume of fuel than extracting, processing, shipping, and burning the diesel does. At some point future advances in technology might mean the biodiesel alternatives improve to the point where they emit less CO2, but we aren't there as a civilization yet.

Swapping batteries is 100% the smarter solution. But that would mean unified battery technology and compability, and since there are different manufacturers with "secrets" thats not something I see happening. On top of that, these big batteries are not cheap, and they also degrade, so there is a cost on top of the raw electricity stored to replace faulty and degraded ones which makes it more expensive still. Trains are cheaper, but for timely transportation they are too "big" in capacity which means they don't drive as often in order to not drive empty. And we don't have that many rail lines anyways. Smaller trains would be a solution, or highly sopohisticated fast automated loading and unloading terminals to come closer to truck level speed in that logistic chain of events. But then also : "Deutsche Bahn" Honestly, the smartest way to reduce emissions on the topic of grocery shopping would really be electric powered drones that can carry your daily shopping so noone pulls out a car to waste a ton of energy to move the heavy car and us useless fleshbags around. In terms of the expensive electricity we are ways behind anyways. Africa is getting wise, which means there won't even be cheap importable nuclear energy from france in a few years, because they are practically "stealing" the uranium from their old colonies. My favourite idea is still to dig 2-5km deep holes and get some geothermal steam up and running, there is nothing preventing us from doing that. Just send a tunnel bore machine down vertically instead of horizontal for a change. Something like this could easily provide our baseload. But I bet some critics will say that we are cooling down our core, shutting off our magnetic field and we will all perish from solar radiation. In a few million years. Welp.

European countries already have overhead power lines and pantographs on their trains so it's an extension from an existing market. It would be a lot more costly to do this in North America, at least till doing this in Europe develops and production in Europe underwrites the costs. I wonder how an inductive system using AC transmissions and trenching a cable into the pavement would compare in costs. I think South Korea had a pilot project with mass transit for this but we never heard of it again. The inductive system would've been easier for private cars to use as there would be no need for pantographs to reach the height of the overhead wires. When compated to building the supports for the overhead wires, the costs of trenching the cable into the road might be comparable though maintenance would probably be more costly however also less likely to be needed. Keep in mind that not every mile would need to be electrified, just enough to recharge the batteries while still enroute. To be honest, if I was to go with an overhead approach, I would be tempted to go with microwave beamed power from phase array towers especially since trucks have all that roof space over the trailer, sure the efficiency of the power transfer would only be 80% but the same is true with inductive cables under the road. Phased array beamed power could be selective to service subscribers instead of to all on the electrified portions. And yes, there are RF power transmission links in grids so wireless energy transmissions of that much power is possible and are being done.

@@Robbedem Larger capacitive energy losses true though underground power lines do exist so it's not prohibitive and less conductive road fill could be used as well as decent dielectrics, but shallow trenching in the established thoroughfare of an asphalt road is inexpensive versus construction of support towers which may be obstructions in themselves as well as vulnerable to accidents and weather and may require additional right of way besides and above the roads. Right of ways are always the most costly of issues and the supports must stand somewhere and it can't be in the road itself but cantilevered over the road. The costs may be comparable as the wire needs to be shallow. Also, as I've said, there's also beamed phased array RF power from fewer towers, likely existing telecommunication towers that can be targeted to subscribed vehicles.

I agree with the idea late in the video (also posted in some of the comment threads) that the best way to achieve electric freight (and passenger) transport would be by rail, including a major expansion of rail networks. That said, trucks (and buses) running under the wires are a reasonable way to get things (and people) the last few kilometers in places where it is hard to put rail or where the amount of traffic doesn't (yet) justify it.

I’m in the swap out the batteries column. I use power tools every day and when the battery dies, you have one in the charger ready to go. You could have the battery mounted under the chassis and come in a standard size so it would fit all cars.

I can't see how those power lines would actually be mechanically reliable to withstand continuous contact- and since the sample size was so small, we probably would have any real data for a long time!

Also, another aspect is cold weather. It can be frustrating to be stuck in a blizzard area a few days at a rest stop, but dangerous with no way to get heat and power. Battery powdered trucks is solving the wrong problem. In order to make batteries viable things would need to be transported in smaller quantities over smaller distances and infrastructure be built for a lot of parking and charging.

Just a note about trains: That a lot of tracks already exist doesnt mean you could just shove more freight trains onto them. Many lines are already used at capacity and actually building more rail infrastructure is basically impossible as a private company, even ignoring the huge cost, just because of insane government regulation of it. You have the same problems with providing that electricity, although trains are more efficient than trucks at least. Plus you'd probably have to build more locomotives too since its not like there's just an infinite supply of them ready to use, just like electric trucks. So that probably leaves the biggest advantage just being that you wouldnt need any batteries.

Sabine at her best - her channel is sooo interesting

This is a helpful video. It highlights the same issue that has challenged electrification from its beginnings, a very long time ago. The cost of the infrastructure is very high and it isn't cost effective, unless there is enough revenue from the traffic using it to pay for it in the long term. We hear everyday about electrification of road vehicles, but they only make up a relatively small part of total CO2 emissions (around 10%, if that's correct). I am somewhat baffled why there is so much attention on vehicle electrification and so little (apparently) on the really significant emitters of CO2? To give a simple example, I could easily do away with my gas fired home heating system and do the job using electricity (CO2 free, hopefully), if it didn't cost so much. That's the reason for gas fired heating systems in the first place. They are much cheaper to use. As best as I can work out, I can't see that CO2 emissions will fall by the amount that is required, based on the current plan. Why is this, I wonder?

To make it more efficient and safe we could string hundreds of cars together using set routes with an overhead cable and pantograph system so the cars are always charged.

I think a better solution might be to 1) build out charging infrastructure - especially at loading docks. 2) use electric trucks for shorter routes. 3) Anticipate the future based on declining battery prices, improving battery performance, and improving charging infrastructure. 4) Consider alternative ways to solve the problem. Like an extra set of wheels that can be mounted mid-trailer that has a battery and an electric motor. You get an electric-powered acceleration boost that is mostly fed by regenerative braking. Etc. It seems that in 3-5 years there will be no need for the wires because other technologies will have already solved the problem.

In general, the existing Electric trucks operate at a relatively low electrical efficiency. Miles per kWh is pretty low for all vehicles - but Tesla is noticeably better. Tesla is so far ahead that other tuck manufacturers said Tesla was lying about semi mileage - that it was impossible due to physics. Tesla is replacing its diesel trucks now and they have an exclusive arrangement with PepsoCo. I think in 18 months Tesla will have learned what it can learn about how to manage electric truck fleets delivering cars and beverages. Then they will sell trucks, charging stations, and huge batteries to all those who want a reduction in shipping-related costs...

I'm so glad we can put the greatest minds in science together to reinvent trains again.

This illustrates a common factor that actuvists and the public often don't understand. Sometimes (often, actually), a seemingly "obvious" solution doesn't take into account the ugly Real World factors like logistics, transition costs versus utilizing established infrastructure, and cost. That's why quick swap batteries make more sense rhan trying to recharge EV or hybrid trucks on the highway, and why hybrid automobiles usually make more sense for more people than plug-in EVs. Because they dont inpose as huge an infrastructure cost, are more easily integrated into the existing infrastructure , and have fewer of the shortcomings of the "ideal" (or "idealistic") solutions that would effectively eliminate exhaust emissions directly drom the vehicle (again, it doesnt really help much to have an EV if you're just getting the electricity from it from a grid whose backbone is fossil fuels... ubkess thise fossil fuel plants are significantly lower emmission per unit of power than the engines of the IC vehicles the EVs are replacing - and every kW/hr of power used to charge the EVs means a kW/hr (we're going to disregard theoughput losses just for simplicity) of the oldest, dirtiest, least efficient power production plant you *can't* retire without cutting a kW/hr of end user need elsewhere. (This last is why I'm so in favor of hybrids versus EVs or hydrogen - hybrids integrate almost seamlessly into the existing transport infrastructure across the board, do not impose as great a strain on existinf road infrastructure (batteries are heavy, and EVs are invariably heavier than their IC equivalents due to the mass of the batteries), do *not* impose any *new* draw on the electrical grid in service, and yet are hyper efficient compared to typical IC-only vehicles. They even impose less strains on the production end than EVs, because their batteries are invaiably much smaller than a pure EV, meaning lower requirements for rare earth elements to produxe them.(

of course it works. it's like giving blood through a tube from left arm to right, with only a little loss from spillage and pump drive. still, there may be some convenience in choosing when you make noise..

I'd like to see them changing lanes and getting into towns and outside towns provided that in De the highways are atually interconnecting towns. And is somehow politely to free up the first lane so the cars to get into and onto the highway.

In the mean time in Sweden, we enjoy an electricity mix of about 50 g/kWh compared ot Germany's about 500 g/kWh (source: WWF "Climate Score Cards", 2009)... since we get most of our electricity from hydropower (8-10 g / kWh) and nuclerar power (3-5 g / kWh). Unfortunately, we have a sortage of power capacity meanng that we have not been able to get rid of the reserve power capacity for high demand days, and those kick up the emissions since they are fossil fueled.

Is electricity more expensive than diesel? While driving a car in Denmark, I don’t find that to be the case. When I compare the Northpool elevtricity prices and the diesel price without tax, electricity is also cheaper.

So we need rental garages with an electronic network. Have them near a conglomerate of all public transit. Transfer as many of the downtown roads into pedestrian only. Electrify major routes. The vehicles would still require small batteries for different amounts of range off-grid. My understanding of power generation; small engines are less efficient than large engines, so power plants capture more energy from fuel than a car or truck. Making a power grid to support them is extremely expensive and time consuming, but in the long run would reduce overall emissions. Its also easier to maintain emission equipment on facilities, than to make sure the people do on their own vehicles. Where i'm from, many vehicles dont even have catalytic converters after they fail because there are no regulations

Many thanks Sabine! Great finger pointing job! This "Energiewende" topic has to be discussed hard and honestly! Heavy trucks cannot be powered by batteries for long distances. The required number of batteries is to heavy ... for a very long distance trip this could reach upto the weigth of the freight. Batteries are only good for the last 100 miles ... or you have to swap (and load) them every 100 miles. Overhead electric lines have been used for ages in public city transport (especially in eastern Europe in the past century and in Bulgaria somewhere still today) with very good experience.

Here the legal entities are asked ... either the EU parliment or/and the national governments ... to provide a legal framework (obligation) for battery swapping and overhead electric lines in time. Otherwise the (german) automotive industry will still block e-mobility for many, many years ... to defend their (endemic battery) monopoly. On the other side ... have a look at China!

Batteries are the way to go. Tesla has proven, you charge a semi with 300 miles or range (480 KM) in 30 minutes. Thus allowing a single driver to travel over 600 miles in under 12 hours with charging. It looks like 700 KWH of LIFePO4(CATL) batteries will be available for around $50,000 this summer. It looks like Europe will up the Z-Emissions allowance to 4 tons. That means a usable and affordable long haul truck should be available by the end of the year.

Why would the electricity to power the trucks be „too expensive“? The cost for the power for my EV is roughly half of the cost for the gasoline for a comparable ICE car. In Germany, where electricity is more expensive than in most other countries. Please explain.

Weird how 70+ yr old technology can fix the cluster we've got ourselves into. If people were incentivized into fixing a problem that will become exponentially more expensive, maybe we could head off the worst (But we won't because there's money to be made now and even more later as long as society doesn't collapse)...

There is a much more practical way for charging cars on the way: inductively from the road without any direct contact. This technology is under research near the old Transrapid Test-Site in Germany. This maglev used a similar power transmission to the train.

I have designed a road made of layers of concrete that generates and stores electricity. Each concrete layer includes a specific extremely low cost additive such as zinc or manganese dioxide with appropriately placed copper mesh at certain points within the layers (to allow electric transmission between the layers). The bottom three layers act as a battery (anode, cathode, electrode) that can store electricity. The middle layers generate piezoelectric power from the weight of vehicles driving over the road that is stored in the lower layers (the battery), and the top layers of cement generate solar power that is also stored in the battery layers. All of the components are highly inefficient from an energy density standpoint (50 pounds of the cement battery only stores as much power as a couple AA batteries...). But the components are very cheap and easy to fabricate. A mile of this type of road passively generates and stores enough power to supply 300 electric vehicles with a mile's worth of power each, per day. A road made of this layered concrete should be as durable as a normal road and would not cost much more than a normal road once appropriate machinery to apply the layers of concrete is developed. Power could be distributed directly from the road to moving vehicles using wireless inductive charging, which has already been developed. Excess power generated by the road would be stored in the road and could also feed the electric grid. I have not pursued this, as I do not think I can obtain a defensible patent. So, I am left just talking about it as a KZread video comment...

Similar concepts have been attempted, google "solar roadways".

I really wonder why so few projects seem to focus on the "swappable battery" part. Especially for trucks and other utility vehicles like buses, were one can assume some degree of standardization.

It has been tried and kinda failed for cars. And it won't be easier for trucks. Swapping those batteries sounds easy, but keep in mind they weigh more than 1000kg. Have high voltage and current. Are flammable, maybe even explosive,...

@@Robbedem I understand fully why it could fail for cars. But there are far fewer manufacturers of trucks than of cars. Thus, there should be far less model variety in trucks than in cars. And the weight, assuming standardization, should not be an issue either. After all, you only would need one single lifter or crane if all trucks used the same battery pack. And the most powerful industrial robot arm lifts something like 5 tons.

The best solutions are often a composit of multiple solutions. I could see the E-highway being a solution for longer trucking runs through select corridors but the swappable batteries would be a solution for shorter runs. When it comes to electric vehicles there is no one size fits all solution no matter how much we try to find one.

Honestly, for this sort of thing I'd prefer some Goubau-line based system, though I'm not certain how well the needed power levels could be pushed through, and the truck-side equipment would need to "play nice" for multiple vehicles to be on the same line at one time.
