Best answer: yes

Ive recently been considering buying an electric car as my current car is starting to get old. I'm trying to research some benefits of owning an electric car, the main arguments that I have come across include that they are cheaper to maintain and that it is better for the environment, if you guys know any other benefits I'd greatly appreciate it.

Best answer: You are correct.

A gallon of gasoline contains an equivalent of about 34kWh of energy.

The battery on most early affordable EV's was around 25kWh or less.

Not only that, but all EV's are designed to use at most only about 85 to 90 percent of the battery's capacity since doing that can help extend the life of the battery.

The good news is that EV's are extremely efficient. (Try going 60 miles on a half a gallon of gas!)

Batteries have cells of chemical storage in them. When sitting alone the cells only produce an electric pressure called voltage. When they are discharged there is a chemical reaction that creates an electric current since the voltage (pressure) is let off. Once the chemicals are used up the battery dead. As the battery charges current is forced through the cells backwards and causes the chemical reaction to reverse.

All battery cells produce a low voltage. But assembling the cells end on end (called a series) increases the total voltage of the battery.

Best answer: Some companies have designs for such wind/sail cargo or tanker ships...time will tell if they become more popular and useful. Modern Rotor Sail designs using the Magnus effect which date back to the 1920's may be an easier and better way to achieve cost reductions in fuel consumption.

"Wind power firm Enercon launched a new rotor ship in 2008, while in 2014 Norsepower added its first rotor sail to a cargo ship owned by sustainable shipping firm Bore. Promising lightweight and relatively cheap materials and designs, combined with higher oil prices and the need to reduce emissions, mean rotor sails could now take off.

The 240 metre-long Maersk tanker will be retrofitted with two modernised versions of the Flettner rotor that are 30 metres tall and five metres in diameter. In favourable wind conditions, each sail can produce the equivalent of 3MW of power using only 50kW of electricity. Norsepower expect to reduce average fuel consumption on typical global shipping routes by 7% to 10%, equivalent to about 1,000 tonnes of fuel a year."

"Currently, the shipping industry alone produces 2.2 percent of the world's carbon emissions. The International Maritime Organization estimates that could increase by 250 percent by 2050 if nothing is done to stop it. By switching to the Rotor Sail hybrid method, the savings for the industry would total $7 billion a year, and it would reduce the emissions by the equivalent of 12 coal power plants."

Well coal and natural gas powered vehicles

Best answer: In a state like West Virginia where nearly all energy comes from Coal, an electric car has about the carbon footprint of a gas vehicle that gets 30 MPH. So, better than a pickup, but not better than a small gas-efficient or hybrid car. But coal plants are cleaner, they output less particulate pollution than auto engines; thus they have an advantage if you like fresh air. And electric cars have a much lower carbon footprint an area such as Northern California where almost 70% of energy to consumers is from non-greenhouse sources.

Best answer: Of course.
Coal power stations are about 35% efficient, add in losses from transmission lines, transformers, battery chargers, battery losses and the modern internal combustion engine is way more efficient.
Wind solar and hydro will never supply enough energy for us all to drive EV's and until we have enough nuclear power (not looking likely for a long time) EV's will always cause more emissions.

If you are asked by kids "Why don't planes go against the earth's rotation to reach their destinations?", How will you answer it scientifically?

Best answer: Rare metals. Fossil fuels have hundreds of years to go before they run low.

Best answer: LOL will this do?

Best answer: If your school had copies of those records, they probably still have them. Ask your old school.

Any side effects? I live right near one now in an apt and I hear it buzzing lol
