Whether it’s rocketing us into space, bringing us all together, building astounding edifices, or answering fundamental questions about who we are and where we come from, here are our picks for nine of the most ambitious tech projects in history.

European X-ray Free Electron Laser

The most recent completed project on this list, the European XFEL — a.k.a. the world’s most powerful image-producing X-ray laser — officially opened for business in Germany in September. A giant laser located 125 feet below ground, in a 3.4-kilometer tunnel beneath the northern city of Hamburg, the XFEL is capable of recording images of biochemical reactions as they happen.

“This way we hope to get a new understanding of the fundamental steps of emerging chemical reactivity,” Professor Christian Bressler, one of the scientists involved in the project, told Digital Trends. Plus, who wouldn’t love a massive underground laser?

The world’s largest hydroelectric dam, China’s Three Gorges Dam cost a whopping $37 billion to build, and generates 11 times the power of America’s Hoover Dam. Stretching 410 miles on the Yangtze River in China’s Hubei Province, the dam opened in 2003 after a decade-long construction process. Last year, it generated a massive 93.500 TWh, slightly less than its 2012 record of 98.100 TWh.

However, while certainly an astonishing example of large scale engineering, the Three Gorges Dam has also been controversial — not least because building it displaced well over 1 million local residents.

Apollo space program

Every item on this list is an example of the power of technology in action. However, nothing screams “we’re living in the future” quite like the results of the 1960s’ Apollo space program, whose crowning achievement was placing man on the Moon on July 20, 1969. In all, six Apollo missions landed on the Moon between 1969 and 1972. (Apollo 13 was supposed to, but failed on account of a spacecraft malfunction.)

A towering achievement for humanity, the Apollo missions are the precursor for the continuing space exploration in the years since, and remain a source of inspiration to millions.

International Space Station

Picking just two space-related mega projects for this list wasn’t easy. But there was no possible other choice for a second entry than the International Space Station (ISS). Launched in 1998, and built by 14 different countries working together, the ISS represented a new age in collaborative space research following the end of the Cold War.

Costing an eye watering $150 billion, it is the largest human-built creation ever launched into space, and is even visible from Earth with the naked eye. A staggering achievement.

DARPA’s CALO project

Sponsored by the U.S. Defense Advanced Research Projects Agency (DARPA), CALO was a five-year, 500-person project which ran between 2003 and 2008. The project name was short for Cognitive Assistant that Learns and Organizes. Its goal was to bring together various different aspects of artificial intelligence including machine learning, knowledge representation and natural language processing to build AI tools for the military.

One notable technology which resulted from the project? The arrival of smart A.I. assistant Siri, which Apple debuted back in 2011. If you’ve ever wondered where we got A.I. technology that allows you to speak to a computer and get an informative answer back, it’s DARPA you need to thank.

Human Genome Project

Running from 1990 until 2003, the Human Genome Project (HGP) was an international scientific research project which set out to sequence and map human DNA; allowing us to read nature’s blueprint for forming a human being. Thanks in part to the Human Genome Project, today anyone can have their genetic makeup sequenced for just a few thousand dollars — opening up a plethora of possibilities for things like proactive medicine that’s tailored to the individual.

Large Hadron Collider

Located 300 feet underground on the border of Switzerland and France, the Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. Costing $9 billion to build, and first switched on back in 2009, the LHC is a 27-kilometer ring of superconducting magnets designed to help unwrap the secrets behind… well, pretty much everything to do with high energy physics.

To achieve this, it smashes almost inconceivably tiny particles into one another at incredibly high speeds in an attempt to simulate conditions found in our universe at the time of the Big Bang. So a bit like monster trucks for physicists, then.

Manhattan Project

No other project on this list — including the Moon landings and the creation of the internet — has shaped the world to quite the extent of the Manhattan Project. A giant R&D project led by the United States between 1942 and 1946, the Manhattan Project drew on pioneering work involving nuclear physics and chemistry to build the world’s first atomic bombs.

The resulting weapon helped end World War II, cost hundreds of thousands of lives, and forever changed the course of international politics and warfare.

EVs top gas cars in German reliability report — but one weak spot won’t quit
future electric cars 2021 volkswagen id4 official 32

Electric vehicles are quietly crushing old stereotypes about being delicate or unreliable, and the data now backs it up in a big way. According to Germany’s ADAC — Europe’s largest roadside assistance provider — EVs are actually more reliable than their internal combustion engine (ICE) counterparts. And this isn’t just a small study — it’s based on a staggering 3.6 million breakdowns in 2024 alone.
For cars registered between 2020 and 2022, EVs averaged just 4.2 breakdowns per 1,000 vehicles, while ICE cars saw more than double that, at 10.4 per 1,000. Even with more EVs hitting the road, they only accounted for 1.2% of total breakdowns — a big win for the battery-powered crowd.
Among standout performers, some cars delivered exceptionally low breakdown rates. The Audi A4 clocked in at just 0.4 breakdowns per 1,000 vehicles for 2022 models, with Tesla’s Model 3 right behind at 0.5. The Volkswagen ID.4, another popular EV, also impressed with a rate of 1.0 – as did the Mitsubishi Eclipse Cross at 1.3. On the flip side, there were some major outliers: the Hyundai Ioniq 5 showed a surprisingly high 22.4 breakdowns per 1,000 vehicles for its 2022 models, while the hybrid Toyota RAV4 posted 18.4.
Interestingly, the most common issue for both EVs and ICE vehicles was exactly the same: the humble 12-volt battery. Despite all the futuristic tech in EVs, it’s this old-school component that causes 50% of all EV breakdowns, and 45% for gas-powered cars. Meanwhile, EVs shine in categories like engine management and electrical systems — areas where traditional engines are more complex and failure-prone.
But EVs aren’t completely flawless. They had a slightly higher rate of tire-related issues — 1.3 breakdowns per 1,000 vehicles compared to 0.9 for ICE cars. That could be due to their heavier weight and high torque, which can accelerate tire wear. Still, this trend is fading in newer EVs as tire tech and vehicle calibration improve.
Now, zooming out beyond Germany: a 2024 Consumer Reports study in the U.S. painted a different picture. It found that EVs, especially newer models, had more reliability issues than gas cars, citing tech glitches and inconsistent build quality. But it’s worth noting that the American data focused more on owner-reported problems, not just roadside breakdowns.
So, while the long-term story is still developing, especially for older EVs, Germany’s data suggests that when it comes to simply keeping you on the road, EVs are pulling ahead — quietly, efficiently, and with far fewer breakdowns than you might expect.

You can now lease a Hyundai EV on Amazon—and snag that $7,500 tax credit
amazon autos hyundai evs lease ioniq 6 n line seoul mobility show 2025 mk08

Amazon has changed how we shop for just about everything—from books to furniture to groceries. Now, it’s transforming the way we lease cars. Through Amazon Autos, you can now lease a brand-new Hyundai entirely online—and even better, you’ll qualify for the full $7,500 federal tax credit if you choose an electric model like the Ioniq 5, Ioniq 6, or Kona EV.
Here’s why that matters: As of January 2025, Hyundai’s EVs no longer qualify for the tax credit if you buy them outright, due to strict federal rules about battery sourcing and final assembly. But when you lease, the vehicle is technically owned by the leasing company (Hyundai Capital), which allows it to be classified as a “commercial vehicle” under U.S. tax law—making it eligible for the credit. That savings is typically passed on to you in the form of lower lease payments.
With Amazon’s new setup, you can browse Hyundai’s EV inventory, secure financing, trade in your current vehicle, and schedule a pickup—all without leaving the Amazon ecosystem.
It’s available in 68 markets across the U.S., and pricing is fully transparent—no hidden fees or haggling. While Hyundai is so far the only automaker fully participating, more are expected to join over time.
Pioneered by the likes of Tesla, purchasing or leasing vehicles online has been a growing trend since the Covid pandemic.
A 2024 study by iVendi found that 74% of car buyers expect to use some form of online process for their next purchase. In fact, 75% said online buying met or exceeded expectations, with convenience and access to information cited as top reasons. The 2024 EY Mobility Consumer Index echoed this trend, reporting that 25% of consumers now plan to buy their next vehicle online—up from 18% in 2021. Even among those who still prefer to finalize the purchase at a dealership, 87% use online tools for research beforehand.
Meanwhile, Deloitte’s 2025 Global Automotive Consumer Study reveals that while 86% of U.S. consumers still want to test-drive a vehicle in person, digital tools are now a critical part of the buying journey.
Bottom line? Amazon is making it easier than ever to lease an EV and claim that tax credit—without the dealership hassle. If you're ready to plug in, it might be time to add to cart.
