Electric cars can’t save climate: Experts

London, June 18 (IANS) The hope that battery-operated cars can save the earth’s climate by reducing carbon emission is just a ‘fantasy’.

According to experts, the technology used for electric car batteries is so backward that they will die within two years.

The so-called energy efficient cars will be extremely expensive and cover far less distance on one battery charge than the manufacturers claim, they said.

The research carried out by the Institution of Engineering and Technology suggests that claims about the performance of electric vehicles are ‘pure fantasy’.

The researchers found the batteries are likely to burn out within two years, requiring expensive replacements.

The batteries, which use the same lithium-ion technology as mobile phones, are unlikely to be able to run for more than 100 miles (160 km) between charges, the Daily Mail reported.

Experts said the gap in performance between conventional cars and electric vehicles is so huge that consumers will not want to convert their vehicles to electric ones.

Citing the examples of Ford Focus or Volkswagen Golf which is capable of travelling more than 360 miles (576 km)on one tank of fuel, the researchers said, for an electric car to offer a similar level of performance, the batteries alone would weigh 1.5 tonnes.

They would be larger than an entire conventional car and cost approximately 100,000 pounds sterling, they warned.

Electric fish cart introduced

It can carry one tonne of goods and costs Rs.1.30 lakh

TIRUCHI: An economically viable and pollution free electrically operated rickshaw, popularly known as fish cart or thattu rickshaw was introduced in the city on Monday.

Collector T.Soundiah flagged off at the Collectorate campus the first electric fish cart launched by Punjab Trading Centre, its distributors. The distributors told media persons that the electric rickshaw would be a boon to small vendors and traders. The rickshaw had rechargeable battery back-up for about seven hours and consumed only 10 to 15 units of power.

They pointed out that even though the fish cart had the capacity to carry one tonne of weight the Government gave permission to carry only 450 kg. It has several facilities including good seating space for the loadman and a maximum speed of 20 km per hour. The rickshaw is priced from Rs.1.30 lakh to Rs.2.50 lakh.


Alaskan teen builds eco-car to combat global warming

Alaska’s Bart Grabman hopes his electric VW Bug will help minimize his carbon tire print.

As a teenager living in Alaska and an avid skier, Bart Grabman knows all about snow. And he could see first hand that global warming meant less snow and an earlier spring … in other words … terrible conditions for skiing. What Bart didn’t know much about was cars, but that didn’t stop him from taking on a project to convert a gasoline-powered car to electric, reducing his overall contribution to the greenhouse gases that cause global warming. Here’s what Bart had to say about his electric Volkswagen Super Beetle.

MNN: What inspired you to build an electric car?
Bart Grabman: I was taking a class at school called Passages, and the purpose of the class was to take something that you’re interested in and expand on it in some way. For instance, in the past, one student who had an interest in carpentry built a gazebo for students to enjoy during lunch. I had two interests that I wanted to expand upon. I wanted to do something to help the environment, and I wanted to learn more about cars. So I thought it would be interesting to combine the two ideas into one project. Building an electric car just seemed like a logical next step.
Is the car finished?
I haven’t finished it yet, but it’s pretty close. It still needs some minor wiring … I have 96 volts of car batteries to power it and I still need to wire this to the existing wiring that came with the car so that everything functions correctly. I’ve taken out for short trips in front of my house, but it’s not ready for longer trips yet.
How much did you know about cars before you started this project?
I pretty much knew nothing about automotive technology when I started this project. But I’ve done a lot of learning. One good thing is that I choose a VW Super Beetle over a more modern, complex car. This has been really helpful because it’s relatively simple in terms of the mechanisms and the motor. The VW Super Beetle is pretty basic so it was a good place to start … especially with my lack of knowledge.
If you were to start this project again knowing what you know now, what would you do differently?
I would have started with a different car. I know I said before that it was a good idea to start with a car that is simple. But the one that I got … well, it had seen better days. The floors were rusted out and the interior wasn’t it good shape. I’ve had to spend a lot of time working on those types of things. I think if I’d chosen a better car to begin with, it would have been easier going.
What would you say has been your biggest obstacle in completing this project?
Time and money. I’m a high school student, and I have a lot of stuff going on, so I don’t have a lot of time or money to spare. But there have been a lot of people who have helped me out on this project in some way or another. So I’ve never had any trouble getting things done when I do actually work on them. But just finding that time is one of the hardest things.
What is the environmental issue that concerns you the most?
I’d have to say global warming. Being from Alaska, where more than half the year here is snow, I’ve noticed more recently a decline in the snow levels. Springs are earlier and we have record-breaking fires in the state every year because its drier and the warmer temperatures bring more pests that kill the trees. Global warming is very evident here.
What advice do you have for other teenagers who are looking to try a project like this?
Find something that you’re interested in and don’t be discouraged by setbacks because there will of course always be some setbacks … if not many. But the results will definitely outweigh the troubles. As long as you follow through, it’s going to be a very rewarding experience when you’re finished.
