How much energy is lost in brakes

Haroon — Mon, 31 Jul 2017 15:16:22 +0000

Braking in automobiles is very frequent, particularly in an urban built-up environment. Huge amount of energy is lost as heat as a result of braking. Even on a highway, braking event can mean loss of huge amounts of energy. Consider for example the sports car Regera, which has a combined horse power of more 1500 hp. It can reach speeds of over 300 km/hr. If the car is brought to a complete from 300 km/hr in the shortest possible time, than it has been estimated that during the braking process, an average of 1 MW power is dissipated. The process

Environmentally friendly Marine Transport

For almost a century, the emissions released though marine industry were ignored. Ships got bigger, sea based transportation cost slide down but the emissions continued to climb. Today we have container ships like Madrid Maersk thousands of containers in one go. They can shift cargo weighing over 196,000 tons. Large ships are still the most environmentally friendly way of moving freight across large distances. It has been reported that for very large container vessel the CO2 emission were only 3.0 gms per tonne-km as opposed to 435 gms per tonne-km for aircraft. Sea based transport makes up about 3% of the

Chevrolet Bolt- Post Launch Review

Haroon — Wed, 05 Apr 2017 14:15:29 +0000

The Chevrolet Bolt was launched by GM in December 2016. As of March 2017, it was available in only a few states in the US, but will be available nationwide from mid 2017. Since its launch, it has made a strong start. It sold 579 units in the first month (December 2016) and 1162 in the second month (January 2017). The numbers are stacking up quickly and there is speculation that by the end of the year, GM would sell upward of 30,000 units of Bolt. So far it is the only EV in the market with over 200 mile range and affordable price tag of 37,495 USD.

All you need to know about Electric & Hybrid Vehicles

Haroon — Sat, 11 Mar 2017 11:51:42 +0000

In this post, all the information you need to know about electric cars will be listed so that it helps you in making the right decision and manage your expectations. What is an electric car and what are the electric car types? By definition, an Electric car is a vehicle that is propelled by one or more electric motors. There are at least 4 different types of electric cars. Let’s have a look at what they are: Pure EV (Electric Vehicle) No IC engine Only electric drive Battery pack size is large (20-80 kWh) Example: Nissan Leaf, Tesla Model S

Jaguar I-PACE Vs Tesla Model S

Haroon — Tue, 28 Feb 2017 13:33:12 +0000

So far Tesla Model S has held the crown for the best high-end, luxury pure electric sedan. And deservedly so, it has been the best-selling electric car for two years in a row (2015 and 2016). What is remarkable is that the Model S leapfrogged Nissan Leaf which had a 2 year headstart and was also at least £25000 cheaper. Tesla ventured into EV market when all the major OEMs were sitting on the fence despite the huge monetary and engineering resources at their disposal. It has to be mentioned that Tesla Roadster that proceeded Model S was the defining car

Can a Tesla Model 3 circumnavigate the Moon?

Haroon — Fri, 12 Aug 2016 15:32:51 +0000

Electric cars work in space. In fact all wheeled vehicles to venture outside our planet thus far have been electric. Starting from the Soviet’s first lunar vehicle the Lunkhod 1 to the Mars Opportunity Rover (MER-1 ) all had electric drive. While electric cars have been in used space for almost half a century yet on earth, we have only recently come to terms with the space-age transporter. In fact some of the satellites can also be classified electric vehicles as they use electric propulsion systems. The improvement in the electric vehicle technology particularly in the last two decades makes it a compelling

Low price Electric cars in 2016

Haroon — Fri, 05 Aug 2016 10:05:37 +0000

The great news for the EV community is that electric cars price is dropping. One main reason is the announcement of Tesla Model 3 which is a high spec electric car, that will be priced modestly (35,000 USD or 26,500GBP ), when it is rolled out in 2017. It should be noted that when the Nissan Leaf was launched, bulk of its price was its battery cost. In fact in 2010, the battery alone in leaf would cost US$18,000 (13, 706 GBP). The battery technology has since improved and the costs have come down. Tesla will be producing their own batteries

Chinese Elevated Bus, is it the real deal?

Haroon — Thu, 04 Aug 2016 09:49:51 +0000

China finally field tested its much hyped “Straddling” bus. The inaugural test was carried out in the city of Qinhaungdao in Hebei province. The bus will be running on specialized tracks and will provide 2 meter clearance for traffic to pass underneath its belly. The current test route is only 300 meters long but through this, the system will be able to iron out any unforeseen factors. This transport system has been termed as TEB (Transit Elevated Bus). If it becomes a success it could provide mass transit solution to many congested cities around the world. Experts have suggested that

Electric Aviation Evolution

Recently Solar Impulse caught eyeballs and captured imagination with its long duration flights across the US and the world. However, contrary to the popular belief, electric aviation is not a new concept. In fact it was as early as 1883 when airship made by the French Engineer Gaston Tissandier used electric propulsion. Similarly, even in the early 20th century, not only airplane but tethered copters were designed with electric propulsion. All of them had limited flight duration and practicality. Solar Impulse 2 in particular gain popularity as it was not only picked up by main stream but also social media. Observers from around the world

This infographic details the chronological advancement of battery technology and how it has impacted electric propulsion. Electric propulsion can have an energy efficiency of over 90% making it potentially the cheapest form of transport. Furthermore it provides the flexibility of storing energy if decrease in momentum is required. In all electric propulsion is an avenue that can potentially reduce our fossil fuel addiction and increase sustainability. The era of pure electric propulsion in land, air and sea is on the horizon. Much of it is reliant on further increase in energy density of battery. Contrary to the popular belief, electric
