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.

Check out the video above and the entire article. It’s a truly amazing story and I’m dying to see this bike out there. For $20 bucks I’ll definitely get one!

Chevy Volt’s progress…A step in the right direction

General Motors first began selling the Chevy Volt, as the first ever plug-in hybrid vehicle, in December of 2010. According to the Environmental Protection Agency (EPA), the Volt achieves about 94 miles per gallon. However, with a price tag of around $40,000, consumers have been slow to jump on board with the plug-in electric car concept. In fact, production was halted back in March-April, 2012, due to sluggish sales. However, General Motors resumed production this past April, a week earlier than planned, as Volt sales have begun to turn around. Some say that this past summer’s high gas prices have encouraged more consumers to invest in the Volt. The following is an article, out of the NY Daily News, discussing the Volt’s return:

What a difference a few months made for the Chevy Volt. From underselling political deadweight to automotive press darling, GM’s plug-in hybrid electric vehicle went back into production this week after a shorter-than expected shutdown announced in early March to reduce the inventory levels of unsold vehicles.

At that time, the Volt’s future looked bleak — it was being rounded on by US Republican presidential candidates and was still suffering from the aftereffects of a series of damaging headlines after a federal investigation into battery safety.

But that was then and this is now.

Check out the entire article. It’s inspiring to see that although progress has been slow, we are moving closer to achieving energy independence and reducing our carbon footprint…One car at a time.

Urban farming in Cleveland

When you think of a farm, you think of a classic rural image like the one above. But with the emergence of urban farming, the idea of farmland is changing. Older cities like Cleveland and Detroit are starting to use land in the inner city area for farming purposes, and the urban farming trend is starting to grow.

The Cleveland Plain Dealer has an article about the emergence of urban farming in Cleveland:

Old MacDonald had a farm, but probably not on an abandoned city lot tended by a farmer from Burma and supported by some of the top restaurants in town.

Cleveland, however, has such unconventional growing places. After only a few years of operation, they are bringing home surprising harvests.

Taut-skinned eggplant and fragrant parsley are being snipped off a row and, within minutes, walked three blocks to Flying Fig, Great Lakes Brewing Co. and other popular dining spots in the city’s Ohio City neighborhood. Off East 55th Street, a flower and vegetable farm provides cherished jobs for folks with developmental disabilities.

A few forgotten acres in the Kinsman neighborhood are now a green training ground for farming entrepreneurs. And a vineyard in Hough hasn’t made its first bottle of wine yet, but the vines look good, and the first cork is expected to pop next year.

Check out the whole article and you can see how an economic ecosystem is being built around these farms. The potential is staggering. It’s also interesting to read how the local restaurants are supporting these efforts by using these farms as a source of fresh fruits and vegetables, and you even have Great Lakes Brewery growing hops for their craft beers.

5 Easy Ways to Turn Your Home Green

Turning your home green does not mean grabbing a can of paint and changing the color. If you are truly interested in protecting the environment, turning green will help you to reduce your carbon footprint. Here is a list of fairly easy ways that you can contribute to the going green effort and turn your home into a more energy efficient place to live.

1. Check your appliances to ensure that they are Energy Star listed. If not, consider trading them in for appliances that are. Energy efficient appliances like stoves, refrigerators, washer and dryers are easily found in most stores today. They may be a bit more expensive to purchase but the energy savings you will enjoy more than makes up for the added cost.
2. Check your insulation. If your home is not properly insulated then you are losing heat and cooling air. This will cause your energy costs to increase and makes your home a bit less than comfortable during very cold or very hot days. Installing insulated windows and sealing cracks around your door frames will go a long way in helping you to turn your home green.
3. Speaking of windows, ensure that yours allow enough natural light into your home. Having windows that give you natural light provides you with the ability to keep your lights off during the day. Skylights are an excellent way to conserve energy as they provide you with adequate indoor lighting from the sun. Windows will also improve the aesthetics of your home and cause smaller rooms to appear larger.
4. Think about water conservation. This is an overlooked area in most homes that are going green. Low flow toilets and appliances will cut down on the water that you use. Check washing machines and dishwashers to ensure that they are water efficient. Again, these appliances may cost a bit more to purchase but will considerably lower your water usage, saving you money in the long run.
5. Check your roof. You do not have to install solar panels in your roof to make it energy efficient. A cool roof will help to reflect light as opposed to absorbing it and keep your home cooler during the summer months. Planted roofs are also a good idea as they enable you to grow a garden when you have no yard space available and also provide an added layer of protection from the elements.
