Advantages and Disadvantages of Maglev Trains While the amazing speed that maglev trains boast of make them seem an apt solution for our transport woes, only a proper evaluation of their advantages and disadvantages can help us get a clear picture about the feasibility of putting them to use. WheelZine Staff On December 2,the Japanese JR-maglev became the fastest non-conventional train in the world by clocking an impressive speed of mph. The seemingly impossible speeds that the maglevs boast of, hint at the fact that we have come a long way from the traditional steam engines to sleek, super-fast trains. But is it really a feasible option to go for a maglev network in a country like the United States?

However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels.

Of course, this produces pollution.

But how does the pollution produced by burning fossil fuels to recharge electric car batteries compare to the pollution produced by internal combustion engines? EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plantscan reduce carbon emissions to less than one percent of those currently produced by internal combustion engines.

So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars. What are the advantages and disadvantages?

Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.

Yet another advantage of these rechargeable batteries is that they recycle well. Almost percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.

The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time.

Of course, this is a serious disadvantage. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one.

This system would allow batteries to be recharged outside of vehicles and would greatly reduce the amount of time required to get an EV up and running again after its battery is fully discharged.

Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power.

These collections of batteries are heavy.
