are effective only over narrow frequency ranges‚ are limited in efficiency response‚ and require higher levels of input power. This paper has a twofold contribution. First‚ we propose a dual-stage energy harvesting circuit composed of a seven-stage and ten-stage design‚ the former being more receptive in the low input power regions‚ while the latter is more suitable for higher power range. Each stage here is a modified voltage multiplier‚ arranged in series and our design provides guidelines on component

Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

Electric cars vs the gas oh line cars In the next ten years what the average American drives will be very different than today. Electric cars may phase out gasoline (Gasoline is also known as petrol) in the next couple of decade. Electric cars produce no tailpipe emissions and are much cheaper to fill up than the more common gasoline vehicles. Switching to electric cars will have more benefits than drawbacks in comparison to other fuels such as petrol and diesel. In order to switch to electric
