The risks of hydrogen cars Hydrogen cars face notable risks: flammability of high‑pressure hydrogen, rare but consequential refueling incidents, sparse and sometimes unreliable fueling infrastructure, high and volatile fuel prices, upstream emissions and leakage that can undermine climate benefits, and practical issues like cold-weather performance, limited cargo space, and end‑of‑life handling of pressure vessels. While …

Five Disadvantages of Biofuels—and Why They Matter Now Five key disadvantages of biofuels are: land-use change that can erase climate gains; competition with food crops that raises prices; heavy water use and runoff pollution; technical and air-quality drawbacks, including lower energy density and higher NOx in some cases; and high costs with policy dependence and …
Salvage Title Downsides: What Buyers and Owners Should Know A salvage title typically brings major drawbacks: limited insurance options, difficulty getting financing and registration, uncertain safety and repair quality, steeply reduced resale value, and usage restrictions. In practice, a salvage (or later “rebuilt”) vehicle can be cheaper upfront but often costs more in risk, time, …
How a Transmission Works, Step by Step A transmission takes the engine’s rotating power and, step by step, matches it to road speed by selecting a gear ratio, then sends that torque through shafts to the differential and wheels. In practice, this means the engine’s output first passes through a coupling device (a clutch in …
What Is the Primary Function of a Cam? A cam’s primary function is to convert continuous rotary motion into a precisely timed reciprocating or oscillating motion of a follower. In practice, this lets machines execute exact motion sequences—such as opening and closing valves or driving automated mechanisms—based on the cam’s profile and rotation speed. How …
What a Steering Pump Does and Why It Matters A steering pump pressurizes power-steering fluid to assist your turning effort, making the wheel easier to rotate—especially at low speeds or when parking. In practice, the pump draws fluid from a reservoir, builds hydraulic pressure, and sends that pressure to the steering gear so you don’t …
Is Replacing a Car Battery Easy? Often, but not always. On many conventional gasoline cars, swapping a 12‑volt battery is a moderate, do‑it‑yourself task that takes 15–45 minutes with basic tools. On newer vehicles with start‑stop systems, intelligent battery sensors, or specific battery types (AGM/EFB), the job may require electronic “registration” or coding. For hybrids, …
What Are Car “Blinkers” Called? They are formally called turn signals or indicators. In North America you’ll most often hear “turn signals,” while in the UK, Ireland, Australia, and much of the Commonwealth they’re called “indicators.” “Blinkers” is a common colloquial term, and the same lamps flash together as “hazard lights” when used for emergencies. …

How to Tell If Brake Caliper Pins Are Bad Bad or sticking brake caliper guide pins typically show up as uneven pad wear, the car pulling to one side under braking, overheating smells or smoke from a wheel, clunks over bumps, and pins that don’t slide freely by hand; you can confirm by inspecting pad …
What Is an Automatic Gearbox? An automatic gearbox is a self-shifting vehicle transmission that selects gear ratios without the driver operating a clutch pedal, using hydraulics and/or electronics to manage gear changes.
