3-D Printer Changes Building Industry

Have you heard about the new innovative technology, the 3-D printer? Well, the 3-D printer is a printer which has been recently developed and is presumed as the “ultimate builder” for practically anything. From medical equipment to bones and body parts, the 3-D printer is capable making of countless things.

Until recently, the 3-D printer was only able to print small objects. The 3-D printer has now been designed for larger scaled objects, such as printing houses and other infrastructures. A Chinese company calleded Winsun has claimed to have built 10 houses in 24 hours (see video below). While in other places, such as Amsterdam, there is a company, DUS Architect, that is replacing cement and mortar with bio-based renewable resources to build houses using 3-D printers.

The new technology will be much safer than the conventional method of building and will be cheaper. Alternative materials can be used instead of cement and other common building materials, which are be environmentally threatening. This idea of a machine replacing thousands of construction workers may not sound appealing, but there are some places in the world where there are not enough workers. For example, in developing countries, the working conditions are harsh and workers may not have the correct tools to build a safe house. If a house can be built in 24 hours, people will have a much sturdier and safer house with minimal labor and can be much more affordable.

3-D printers may just be the starting point of a completely different lifestyle for the future. With the countless number of uses it has, 3-D printers can replace many machines and potentially reduce harmful actions such as pollution.

Creating Electricity – the FUN way

Around 1.3 billion people in the world lack  access to a reliable electricity source. What if there was a partial solution to this electricity scarcity? Soccket – a electricity producing soccer ball – is a new innovation that was founded in 2011. This soccer ball generates electricity by converting mechanical energy (from kicking or hitting the ball) into electrical energy.

Soccer is the most inexpensive and popular sport enjoyed worldwide. All you need is a soccer ball whether it be a normal soccer ball or a ball made from straws. You just need a ball and some markers down for goal posts to play.

Soccket is just like any soccer ball except for its high technology. Soccket weighs 17 ounces (1 ounce heavier than a normal soccer ball) and it is embedded with high-coiled sensors that convert energy. A plug is located on the outside for LED lamps or for charging mobile phones. It is estimated that 30 minutes of playing soccer with Soccket can result in up to 3 hours of power for a LED lamp.

In underdeveloped countries, having an off-grid power source, as they mention, is very rare. With the help of Soccket, kids will be able to bring home a light source to help them with their homework, or to read a book at night. The future plan is to distribute Soccket balls to schools so that kids can play and have fun, while generating electricity at the same time.

The project has now expanded to making jump ropes that generate up to 2 hours of electricity with 15 minutes of jumping (about 4 times more efficient than Soccket). With advancing technology and research, the world can enjoy creating energy.

Sitting Leads to Premature Death?

Right now, as you are sitting and reading this blog, you are inviting a premature death. A recent study by Biswas et al. in the Annals of Internal Medicine journal states that sedentary time, i.e. time sitting down, shows a correlation to the risks of cardiovascular disease, type 2 diabetes, obesity, and some cancer types. These diseases allude us to people lacking physical activity however, in the study done by Biswas et al., it is suggested otherwise.

Physical activity is emphasized deeply in our everyday lives. Data shows physical inactivity has led to many of deaths and is believed that physical activity decreases the risk of diseases. However, in the study done by Biswas et al., the correlation between sedentary time and diseases is independent to physical activity. A related study suggests that reallocating 30-minutes of sedentary time everyday showed to be slightly beneficial, whether it be sleeping, physical activity, or even standing up. The study showed unspecific benefits and were not able to come to a conclusion that physical activity was beneficial.

A CNN coverage on this topic by Jen Christensen suggests that a person should stand up every 30 minutes for 1-3 minutes in order to reduce the risks of these diseases. The coverage suggests that when a person is standing up, there are some pressure points in the body which are activated so that the body secretes certain types of chemicals essential for the body. However, when sitting down, the body does not generate these chemicals hence the increase risk of diseases.

 

The next video describes in further in detail on how the body responds to prolonged sedentary time.

Everyone nowadays spends at least half of their day sitting down, whether it be at home watching TV, at work finishing up a presentation, or even sitting down to read a book. Contrastingly, healthy living is emphasized so greatly in our lives. Balancing healthy living and our normal lives can be struggling, but taking small steps can help reach that struggle. Standing up and stretching every 30 minutes or so can help, as well as exercising at least 10 minutes a day can decrease the risk of harmful diseases.
