Human Balloon?

I always wondered if humans could be blown up like balloons ? Not that I'm some kind of freak thinking of new ways to kill people but just out of sheer curiosity . Finally i got my answer after reading this article on Yahoo.

Humans can actually be blown up if you maintain the right air-pressure. Here's the article :

Compressed air turns NZ trucker into human balloon


WELLINGTON, New Zealand – A New Zealand truck driver said he blew up like a balloon when he fell onto the fitting of a compressed air hose that pierced his buttock and forced air into his body at 100 pounds a square inch.
Steven McCormack was standing on his truck's foot plate Saturday when he slipped and fell, breaking a compressed air hose off an air reservoir that powered the truck's brakes.
He fell hard onto the brass fitting, which pierced his left buttock and started pumping air into his body.
"I felt the air rush into my body and I felt like it was going to explode from my foot," he told local media from his hospital bed in the town of Whakatane, on North Island's east coast.
"I was blowing up like a football," he said. "I had no choice but just to lay there, blowing up like a balloon."
McCormack's workmates heard his screams and ran to him, quickly releasing a safety valve to stop the air flow, said Robbie Petersen, co-owner of the trucking company.
He was rushed to the hospital with terrible swelling and fluid in one lung. Doctors said the air had separated fat from muscle in McCormack's body, but had not entered his bloodstream.
McCormack, 48, said his skin felt "like a pork roast" — crackling on the outside but soft underneath.

Subsidized Tractors : A necessity or extravagance ?

Foreword :
Since Pakistan's economy is still by large an agrarian economy i decided to write something related to agriculture.

Now most of you i believe have come across the recent agricultural development programs of the government.One such scheme is to provide subsidized tractors to small scale and medium scale farmers.That would have been a great step given another set of situation but in the current energy crisis its a waste of limited funds.

I know most of you would disagree with me but kindly allow me to explain. If the farmers have no electricity to run their tube wells then what good can the tractors do ? On each tractor their is a subsidy of around Rs2,00,000 . This is not a small amount considering what could have been done with it.

First of all that the same amount of funding should have been used to equip small and medium scale farms with wind turbines or solar energy systems to power their tube wells. Most farms in Pakistan do not require much energy so a small system would be well within the budget allocated as subsidy for each tractor.

Secondly this would offset the farmer's input cost by reducing his energy bills and he will then be empowered to spend the saved money on fertilizers and high quality seeds which will definitely increase the yield per crop. Indirectly the government would be the beneficiary.

Third, the energy saved by shifting these farms onto alternate sources will reduce power outages in urban and industrial areas.

As for tractors,they can be rented on a per hour basis but energy is something without which growth and production is impossible.I just hope the government comes up with such projects that would help resolve the current energy crisis in the country .

Bio-fuels:The true picture !

Recently i came across a blog post from one of my reading list. It was about bio-fuels being used as an alternate energy source.Before you continue to read on please go through the article over here: Spring of Autumn !

Since oil prices around the world are shooting up the low cost of bio-fuels seems to be very attractive. But you have to keep in mind the larger picture.As we all know that land is limited so eventually energy crops for bio fuels will compete with food crops. The farmer will definitely choose to cultivate energy crops as it will result in greater profits for him.This will cause a food shortage throughout the world.

In a country like Pakistan where food inflation is already in the double digits this would mean signing the death warrant of millions of people who live below the poverty line ! Whereas the rich would be happily fueling up their fancy cars with cheaper "cleaner" bio-fuels .

There are several other sources of alternate energy with less negative impacts that are waiting to be tapped . Surely we should work on those rather than bio-fuels which can create an unbalance in the world .
