The 70 kg US$39,000 FlyNano Electric Microlight

 

Finnish aeronautical engineer Aki Suokas launched a remarkable new single-seat aircraft in april at Aero Friedrichshafen. The FlyNano is made entirely of carbon fiber composite, lands and takes off on water, and weighs just 70 kilograms ready to fly. Three variants are available: a 20kW electric-only version, and petrol-engined 24 bhp and 35 bhp models, the latter proposed as a racing version. The Flynano tops out at over 140 km/h, with a service ceiling of 3 km. If you think that’s remarkable, the most expensive of the three variants ex-factory and ex-VAT is just EUR 27,000 (US$39,000) and deliveries begin three months from now.

The FlyNano’s wingspan is nearly five meters, it has a maximum take off weight of 200 kg and it has a speed range of 70 km/h to 140 km/h. FlyNano’s true airspeed is about 140 km/h at 75% power with a theoretical operational distance of 70 kilometers.

The almost exclusive use of carbon fiber has enabled the Flynano to come in at under the magic 70 kg weight limit which determines how a new plane is legally classified. In this class in most jurisdictions, there’s no license required and a minimum of red tape. Of course there’s no passenger and no luggage, but it already rates as a breakthrough in aviation cost-performance.

 

Though the electric version has a limited range of 40 kilometers, the low speed torque and minimal vibration of the electric motor enables the low-speed four-blade prop to be whisper quiet, ensuring you’ll get no complaints from the neighbors.

A transferable buy option will get you a place in the 2011 delivery queue at EUR 900 (US$1300), with 30% payable on delivery confirmation and the remainder prior to delivery. There’s also an optional purpose-built trailer and storage box for the Flynano which retails for EUR 5,300 (US$7,700).

Introducing Lit motors C-1,a self-balancing electric motorcycle

The designers of the fully-enclosed electric motorcycle claimed that it would be able to stand up on its own, thanks to electronically-controlled onboard gyroscopes. Well, while there may not be a C-1 in a showroom near you just yet, the folks at Lit have indeed succeeded in building a functioning prototype of their vehicle. We made the trip to their San Francisco workspace, to have a look for ourselves.

The rather steampunk-looking proof-of-concept prototype is electronically limited to a speed of about 10 mph (16 km/h), and its two scaled-down gyros generate only half of the approximately 1,300 foot-pounds (1,763 Nm) of torque planned for the production version. It turns out that that’s still enough, however, to keep it upright while being piloted around the local streets – or when being yanked sideways by a Land Rover, as you’ll see in our video.

While the vehicle that we saw is still very much a work in progress, Lit Motors president Daniel Kim says that they have learned a lot from making it, particularly when it comes to keeping the weight down on the final version. “I have a couple of ideas for our next revision,” he told us. “I’ve got some tricks up my sleeve for what the real potential of this vehicle will be.”

Kim hopes to be selling C-1’s by 2014. By that time, they should reportedly have a top speed of 125 mph (201 km/h), a battery range of up to 200 miles (322 km) per charge, and space for a second passenger – all for US$16,000.i.e About Rs.8.8 lakh

Kinetic Energy Recovery System | KERS |

So,here goes my first post.ImageThe introduction of Kinetic Energy Recovery Systems (KERS) is one of the most significant technical introductions for the Formula One Race. Formula One have always lived with an environmentally unfriendly image and have lost its relevance to road vehicle technology. This eventually led to the introduction of KERS.

KERS is an energy saving device fitted to the engines to convert some of the waste energy produced during braking into more useful form of energy. The system stores the energy produced under braking in a reservoir and then releases the stored energy under acceleration. The key purpose of the introduction was to significantly improve lap time and help overtaking. KERS is not introduced to improve fuel efficiency or reduce weight of the engine. It is mainly introduced to improve racing performance.

KERS is the brainchild of FIA president Max Mosley. It is a concrete initiative taken by F1 to display eco-friendliness and road relevance of the modern F1 cars. It is a hybrid device that is set to revolutionize the Formula One with environmentally friendly, road relevant, cutting edge technology.

 

Components of KERS

The three main components of the KERS are as follows:

  • An electric motor positioned between the fuel tank and the engine is connected directly to the engine crankshaft to produce additional power.
  • High voltage lithium-ion batteries used to store and deliver quick energy.
  • A KERS control box monitors the working of the electric motor when charging and releasing energy.

B – Electronic Control Unit

C – Battery Pack

Working Principle of KERS

Kinetic Energy Recovery Systems or KERS works on the basic principle of physics that states, “Energy cannot be created or destroyed, but it can be endlessly converted.”

When a car is being driven it has kinetic energy and the same energy is converted into heat energy on braking. It is the rotational force of the car that comes to stop in case of braking and at that time some portion of the energy is also wasted. With the introduction of KERS system the same unused energy is stored in the car and when the driver presses the accelerator the stored energy again gets converted to kinetic energy. According to the F1 regulations, the KERS system gives an extra 85 bhp to the F1 cars in less than seven seconds.

This systems take waste energy from the car’s braking process, store it and then reuse it to temporarily boost engine power. This and the following diagram show the typical placement of the main components at the base of the fuel tank, and illustrate the system’s basic functionality – a charging phase and a boost phase. In the charging phase,

kinetic energy from the rear brakes (1)

is captured by an electric alternator/motor (2),

controlled by a central processing unit (CPU) (3),

which then charges the batteries (4).
