solar cycle that doubles up as electric bike!


VADODARA: A young engineer from the city has developed first of its kind cycle that runs on solar power and also works as electric bike.


With small solar panels installed on a normal cycle, this solar cycle is a zero energy model. After receiving success from its first working model, Abhishek Avrani (29), who had developed the cycle for a school project, plans to make it more affordable for commuters who want to champion the green cause.

"Like any conventional cycle you can pedal this one. If you don't want to pedal, it works like an electric bike," says Avrani, who has developed the solar cycle with a battery and an electric motor. "The battery mounted on the cycle gets charged through the small solar panels mounted on the shed of the cycle. There is an electric motor which enables this cycle to work like an electric bike," says Avrani, an engineering graduate from Vallabh Vidyanagar-based Sardar Patel University, who set up a start-up in 2008 which works on solar based projects. "Advantage of this solar cycle in comparison to electric bike is that you have to leave the electric bike wherever you are once the battery gets discharged. In case of this solar cycle, all you need is to keep it in front of sun shine to charge the battery. Within half-an-hour, it gets sufficient charging to drive for another ten kilometers," he says. According to Avrani, the battery of the solar cycle developed by him gets sufficient charge in two hours to run nearly 25 kilometres.

"A commuter does not need to hunt for electric points in order to charge the battery. All he or she needs to do is park the cycle at any place where it gets sufficient exposure to sunlight," says Avrani. He has developed the working model of the solar cycle equipped with speedometer and LED lights which work on lower power input.

While the youngster has developed the first sample that costs Rs 28,000, he is making more changes to the model to make it cheaper and aesthetically appealing to commuters.

"It is already a light-weighted model, but I am modifying it so that it finds greater acceptance among commuters," he adds.


US man grows new finger after horse bite


NEW YORK: A 33-year-old man in US has undergone a 'miraculous' medical procedure to grow back his index finger which was chomped down by an overzealous horse while he was feeding the animal.

Paul Halpern from Florida managed to save the severed digit and take it to the hospital, but doctors told him there was nothing they could do. Halpern then visited Dr Eugenio Rodriguez, a Deerfield Beach general surgeon who used an innovative procedure called xenograft implantation to regenerate the finger. Xenograft refers to transplantation of cells from one species to another.

Rodriguez created a scaffold of Halpern's missing finger, using tissue from a pig bladder, and attached it to the severed portion. The finger grew into the mold, generating new bone and soft tissue and a new fingernail.

According to CBS Miami, Halpern had to apply pulverised pig bladder tissue to his wounded finger each day and cover it with a protective saline sheet. Rodriguez said the powder stimulates stem cells in the finger to regenerate, which causes the growth.

Google Glass is a wearable computer that has a frame similar to traditional eyeglasses. It follows voice commands to take photos and videos that show the viewpoint of the user.
CHENNAI: When the surgeon's scalpel drew a red line on the patient's abdomen, two blocks away a group of medical students leaned toward their screens.

The procedure was a simple hernia repair, but the surgical team was unusually upbeat as they turned to look at the latest gadget in the operation theatre - the Google Glass worn by their chief.

As the medical fraternity in the west debates the usefulness of the newest device produced by software giant Google Inc, doctors in India have joined the chorus with bouquets and brickbats, even as a surgeon in the city became the first in the country to live-stream a surgery using the Google Glass.

On Tuesday, Lifeline Hospitals live-streamed an upper gastro-intestinal laparoscopy procedure on a 45-year-old man and a hernia repair on a 42-year-old woman to medical students seated two blocks away using Google Glass.

"It felt like I was glancing at my rearview mirror while driving. I was focusing on the surgeries and talking to my students at the same time. At one point, I stopped feeling it was an external device," said Dr J S Rajkumar, chief surgeon of the hospital.

Google Glass is a wearable computer that has a frame similar to traditional eyeglasses. It follows voice commands to take photos and videos that show the viewpoint of the user.

The surgeries were live-streamed on Google Hangout as well. Doctors say the gadget is yet another step forward in opening the doors of the operation theatre. "People need to know what is happening behind those doors. This is one more gadget towards that end. Students can see the surgical procedures through their seniors' eyes, quite literally. This is a phenomenal surgical tool," said Dr Rajkumar.

"We did face some practical glitches like problems with wi-fi and the battery dying early."

Although the gadget is yet to hit the market, Google distributed 2,000 of the gizmos earlier this year for testing before its release to the general public.

Besides being an educational tool, doctors say the technology could be used to view X-rays, MRI images and other medical information as they conduct surgeries. It could also be used to connect with doctors in far flung places, provided their internet connectivity is good.

"The gadget could help professionals access data and communicate with colleagues far away, while getting feedback to improve efficiency and quality of patient care. The possibilities are endless, but at the end of the day any gadget is only as good as the user," said Dr Sai Satish, consultant interventional cardiologist, Apollo Hospitals.

While some doctors say the device could soon become a fixture in operation theatres, some see it as a distraction. "It's too early to celebrate this as a breakthrough in healthcare tools. Unless it is carefully vetted, it could be a disaster for patients," said Dr R Ravi Kumar, director, institute of cardiovascular disease, robotic surgery centre at Chettinad Health City.

He said operation theatres already had gadgets performing the same functions as Google Glass. "I use a camera attached to my head which is live-streamed to audiences in different parts of the world. So what makes this gadget special? We'll have to wait till it hits the market," said the doctor, adding that the price tag of $1,500 was too steep too expensive for many doctors.
