Do electric cars need air?
The electronics, the motor and the battery all need to be cooled. The Roadster and Volt both use liquid cooled batteries with radiators in the front. Aerodynamicists always try to minimize the open area to cut drag but some openings are still needed. Thanks to Torrey for the tip!
Why hydrogen cars are better than electric?
The main advantage of hydrogen cars is that they produce no emissions at the tailpipe – just water. This benefit is the same as with a normal electric car, and puts both at the forefront of emission-cutting tech in the automotive world.
Do electric cars hurt the ozone layer?
A new study suggests that electric cars can create almost twice as much ozone per kilometre as cars powered by conventional fossil fuels.
Do electric cars have transmissions?
Electric cars don’t require multi-speed transmissions because of the so-called “engine” in an electric car, an electric motor. While internal combustion engines require multiple gears with different ratios for power output, electric motors produce a consistent amount of torque at any given RPM within a specific range.
Will hydrogen cars overtake electric?
That’s true to an extent, but hydrogen-powered cars are not expected to replace EVs. Instead, for makers such as Toyota, hydrogen will complement electric power, and there’s a good reason for this: it is, and will be, the cleanest fuel possible.
Why are hydrogen engines a bad idea?
The biggest reason why hydrogen-combustion engines are no good? They create nitrogen oxide, which isn’t good for people or the environment. Even though carbon isn’t part of the hydrogen combustion process, NOx isn’t a compromise as automakers look to zero-emission vehicles.
Why does Elon Musk not like hydrogen?
But Musk’s beef with hydrogen is that while it has the highest energy mass of any fuel, its density is so low that the pressure needed to store it, combined with adding fuel cell technology to create electricity, adds way too much complexity.
How much is a gallon of hydrogen fuel?
Hydrogen fuel is much more efficient than gasoline, but it’s also four times more expensive, roughly equivalent to about $16 a gallon.
