The cardboard bicycle

This seems like the ultimate expression of sustainability in consumer products – a bicycle made entirely out of folded cardboard that costs around $9 to make and can retail at around $20.

A bicycle made almost entirely of cardboard has the potential to change transportation habits from the world’s most congested cities to the poorest reaches of Africa, its Israeli inventor says.

Izhar Gafni, 50, is an expert in designing automated mass-production lines. He is an amateur cycling enthusiast who for years toyed with an idea of making a bicycle from cardboard.

He told Reuters during a recent demonstration that after much trial and error, his latest prototype has now proven itself and mass production will begin in a few months.

“I was always fascinated by applying unconventional technologies to materials and I did this on several occasions. But this was the culmination of a few things that came together. I worked for four years to cancel out the corrugated cardboard’s weak structural points,” Gafni said.

“Making a cardboard box is easy and it can be very strong and durable, but to make a bicycle was extremely difficult and I had to find the right way to fold the cardboard in several different directions. It took a year and a half, with lots of testing and failure until I got it right,” he said.

5 Common Misconceptions About Hybrid Cars

Even as hybrid vehicles increase in popularity, many drivers remain misinformed about the pros and cons of driving a hybrid. Here is a look at some of the most common myths and misconceptions.

Hybrids Are Electric Cars

Hybrid cars have electric engines under the hood, right alongside their gasoline combustion engines. This is why we use the term “hybrid.” Most of the waste and smog generated by a combustion engine is due to stop and go city traffic. Idling, braking and accelerating all waste fuel. Hybrids overcome this problem by using an electric engine at speeds below around 25 miles per hour, and never idling. When travelling on the highway at higher and more consistent speeds, hybrids use their gasoline combustion engines. The electric engine is reserved for passing and quick acceleration.

Hybrids Are Too Small or Too Slow

Because hybrids are powered by regular gasoline engines, with the addition of an electric motor, many models offer more power than their traditional counterparts. Like traditional vehicles, the most affordable hybrids are compact and lack muscle. In addition to those economy models, an increasing number of luxury sedans and heavy pickup trucks are available. Watch for the Mitsubishi Pajero to join the Cadillac Escalade and Chevy Tahoe in the hybrid SUV fray, perhaps as soon as next year. Porsche is producing high performance hybrids for competition as well as for the consumer market.

Hybrids Are Too Expensive

We all know by now that hybrid drivers save money on gasoline, but many drivers consider the initial cost of a hybrid to be too high. Like most new technology, hybrids were expensive when they first hit the market. Now that hybrids are entering the mainstream and competition among car makers is increasing, hybrids are becoming more affordable every year. Hybrids have also become more affordable to maintain. More mechanics are prepared to work on them, and replacement parts have become more widely available.

The Battery Will Not Last

This myth is easy for drivers to believe, particularly if they have ever owned a laptop that was several years old. Unlike laptops, mobile phones and most other rechargeable electronics, a hybrid car never fully charges its battery. By maintaining a maximum charge of around 50%, hybrid engineers have ensured that their batteries will have a long life cycle. Normally, the warranty on a hybrid battery is good for 80,000 to 100,000 miles. Batteries tested up to 160,000 miles have performed like new.

All Hybrids Need to Be Plugged in

Some hybrid models must be plugged in to charge. Others charge their batteries using technology called regenerative braking. When the driver brakes, kinetic energy that would be wasted in a traditional vehicle is captured by the electric motor, and stored in the battery. Many hybrids use a combination of both methods.
