How big is the world’s largest engine? The world’s largest engine has 109,000 horsepower, and it’s a ship engine, a Wartsila RTA96C-14, and it powers one of the largest container ships in operation. Compare that with the Titanic, which had an engine capable of 15,000 horsepower.
The ship is called the Emma Maersk, and yes, it requires 109,000 horses to move it through the water.
The Wartsill-Sulzer engine is one of 25 14-cylendar turbocharged diesel 2-stroke engines in use currently. It’s weight is 2,100 metric tons. Tons! It’s as tall as a small apartment building at 14 meters and it’s 28 meters long.
Limit? 102 RPM. What could you and what couldn’t you move with this engine? Top speed of a container ship like the Emma Maersk with this motor? 31 knots (57 km/h).
Fuel consumption? 6.5 ounces of diesel per cycle.
Energy output? 80,000 KW. How much power does your city require to keep it’s lights on?
Well, there are 86 more of these world’s largest engines on the way, and there are larger and more powerful engines being planned in various locations.

ETF mining trucks: Don’t Call it a Dump-Truck
ETF Mining Equipment is a privately-held company with headquarters in Slovenia, manufactures the largest trucks in the world for mostly off highway usage. They are known for zero emissions and reduced noise free of diesel engines. Also, more mine output due to vehicle offerings of a overland truck train configuration. ETF is a different kind of company and business model.
The ETF mining trucks start with 250 metric tonnes of payload, with the largest truck capable of 565 tonnes. With such huge payloads and configurations this can mean the capability of hauling 4 times what a competitor company is offering.
Such trucks are a battery electric all-wheel-drive surface mining rig with energy harvesting and yes once again, free of diesel engines or turbines.
As mentioned previously the all-wheel-drive component; this all equates to less weather delays from snow, rain or other conditions. So, likewise the mine can keep producing without downtime. ETF states that their vehicles have a 95% technical availability rating, meaning instead of repairs an exchange of a component is performed and the truck has less time out of service.
The company touts themselves a different kind of company; from the vehicle offering to delivery. When purchasing, the company ships in containers to the mine site parts, whereby ETF assembles the trucks on site. However, there is a minimum purchase order of 6 units.
In consideration of environmental impact and payload, ETF Mining Equipment is definitely worth much consideration for mining corporations. Also, based upon internet research this corporation has delivered to mines in Chile and not limited to a European market.
The robot eats concrete with water so the rebar can be re-used!
What is ERO?
According to the company: “ERO is a Concrete Recycling Robot designed to disassemble concrete structures and enable the building materials to be re-used for new pre-fabricated concrete buildings. Current techniques of concrete demolition requires a lot of power crushing, separation and machinery. Not to mention waste of water in order to prevent dust pollution during operation.
Transferring waste material to recycle stations outside the city wastes time and the end result of which can only be re-used in very limited areas. ERO uses water jets to crack the concrete surface to disassemble concrete and sucks up the mixed debris. It cleanly separates the waste mixture and packages the cleaned material. What was previously waste, now turns into labeled packaged asset to be transferred right away into concrete pre-casting stations to be re-molded into new building blocks. No dust, no waste, no separation.
“Only clean bags of aggregate and rust and dust free rebar remains to be cut and re-used directly. What was the challenge The challenge with this project was to separate materials at the same time with de-construction. Concrete is usually reinforced with a metal mesh inside. Today’s techniques tend to pulverize with brute force which creates a lot of dust and uses a lot of energy. Outcome of the operation creates a mixed mound of waste material which needs to be separated in order to be re-used or sold as second grade metal, or as a filling material. In order to overcome later separation and ease the transport of materials The process had to start with separation on the spot.
“It was a challenge to switch from brutal pulverizing to smart de-construction. Keep the whole process clean and simplify the process. The alternative was a crowded group of operations which would otherwise consume a lot of work time, machinery and energy. Today’s well applied technologies provided me concept level solutions.ERO as a design solution:One of the goals of this project was to provide a smart & sustainable near future approach to the demolition operations that will allow re-using as much as possible.
“Today, operators manually control different sized heavy machinery to smash and crush the concrete structure into dusty bits. All of these machines consume a lot of energy to operate. Water has to be sprayed constantly with fire hoses to prevent harmful dust from spreading around. After the work is done, big machines scoop up the rebar and concrete mixture and transfer them to the recycle stations outside the city. There, the waste needs to be separated manually. Concrete needs to be crushed with power crushers in several stages, end result of which can only be used for simple construction layouts.
“The metals are melted to be re-used. These operations all require heavy machinery.An autonomous fleet of ERO is placed strategically within the building. They scan the surroundings and determine a route with which they will execute the operation. Once ERO starts working. they literally erase the building. ERO de-constructs with high pressure water, sucks and separates the mixture of aggregate, cement and water. Then sends aggregate and filtered cement slurry separately down to the packaging unit to be contained.
“Clean aggregate is packed into labeled big bags and sent to concrete pre-cast stations nearby for re-use.Water is re-cycled back into the system, ERO doesn’t waste water like today’s systems. Packaging unit provides ERO with vacuum suction and electrical power. Turbulence dynamos placed within the air suction route which produces some percent of power ERO needs. ERO uses less than what it gets. Nothing is land filled or sent away with extra operations. Rebar is now cleaned from concrete, dust and rust. It is ready to be cut and re-utilized immediately. Every bit of the load bearing structure is reusable for new building blocks.
“This project is an excellent solution for the complexity of today’s demolition techniques which consumes a lot of energy to create a lot of waste. All around the world concrete is being demolished increasingly to make new ones every day. ERO simply turns Waste into Asset.”
