急初三作文my ideas of inventing在线等！！

I've got plenty of ideas of iventing.The one that I am most keen to invent is a car using no fuel and does no harm to the environment.
As we all know,with the rapid development of the techmology,more and more cars have been used and that does harm to the environment.
If the eco-friendly car is invented,the amount of resources used will be reduced.We will have a blue sky above us;fresh air all around us;clear water in lakes and rivers,and that will make our environment more brautiful and comfortable for us to live in.People will drive their cars without thinking about the environment.
I have other ideas too.And I hope they will be able to make our world better.
