VOD: Bill Nye Tells You Everything You Need to Know about Climate Change

The millenial generation grew up receiving their science facts from a guy with neat curly hair and a wonderful array of bow ties. Many of us are adults now and “Bill Nye the Science Guy” has long been off the air, but that doesn’t stop that magical man of science from trying to save the world anyway. In this YouTube video Bill describes what climate change is, how we got here and what we need to do to stop it.

“This climate science is no longer a matter of opinion, politics or dogma,” Bill says towards the end of the video. By the time the current population of children reaches middle age the human race’s carbon dioxide production will be double the earth’s natural carbon cycle – yet we are already seeing the hazardous effects through higher temperatures and more extreme weather. If we act now we can prevent things from getting worse but we are dangerously approaching the point of no return where we will be forced to recognize a new normal of extreme weather and unbearable temperatures. Why would we ever let that happen when there are so many clean energy sources being made available to us? That’s a question we should probably be taken more seriously.

Did you know this about climate change? Have you tried replicating Bill’s simple experiment? Let us know in the comments below!

8 Things You Didn’t Know About Electric Cars

Tesla Model SAdvocates of the gasoline engine point to the high costs, low speeds and the unproven track record of the electric car as its caveats. However, the facts are clear: electric cars are drastically falling in price, are competing with ordinary driver vehicles for speed, entail far less maintenance and are proving even more reliable than cars using petrol. Bet you didn’t know these astounding facts.

1. Electric Cars Aren’t New Kids on the Block

In fact, electric cars have been around for more than 170 years. Robert Anderson of Scotland is credited with creating the first electric carriage in 1832. Electric cars have, of course, progressed significantly since then, as the technology has improved by leaps and bounds. You now have the option of controlling many of car’s functions from your smartphone. So if it’s cold outside, use your smartphone to start up your car and save yourself some freezing discomfort. Some of the best cell phones of 2013 now have the technology to seamlessly interact with your smart car.

2. Once Upon a Time, Electric Cars Were More Popular than Petrol Cars

Before the twentieth century, there were more electric cars on the road than gas-powered ones. Until the Model T was invented and petrol became readily available, that is. In 1897, all New York City taxis were electric-powered, built by Electric Carriage and Wagon Company in Chicago.

3. Ironically, Electricity Made Petrol More PopularKarma at speed in the fog

At first, petrol cars were less popular because they had to be hand cranked. When the electric starter was installed, it made starting petrol engines easier. So, electricity is what bolstered gasoline engines into popularity.

4. Electric Cars Need Almost No Maintenance

Other than replacing windshield wipers and buying tires, there is virtually no maintenance in owning an electric car. Even the brakes last longer due to the design of electric cars. The Mars Rovers have worked continually for over seven years with no mechanical issues at all.

5. Electric Cars are Speed Demons!

In 1899, the world speed record on land was made by an electric car from Belgium called La Janais Contante. It made history at 68 mph (109 km/h). Today, the world’s fastest electric car reaches speeds of 305 km/h and accelerates from zero to 100 km/h in a mere 2.8 seconds.

6. Electric Cars are More Available, Less Costly All the Time

In 2009, a consumer paid £21,334 for an electric car. Today that price has fallen to £10,990. By 2015, consumers are expected to pay a mere £6,500. Not only are the prices falling, but more vehicles are becoming available. Almost every major auto manufacturer in the world is expected to offer an electric vehicle within two years. Thirteen models are currently available, with 18 to come. The Tesla Roadster, Chevy Volt and Nissan Leaf are just a few of the currently available electric cars to choose from.

7. Charging An Electric Car is Easy

Many consumers fear that charging the car will be difficult, expensive, time-consuming or impossible. However, charging electric cars is cheaper than buying petrol at today’s prices and most owners charge their cars overnight and lose no time at all out of their busy schedules. In fact, as your smartphone charges, so can your car! Increasingly, petrol stations are offering fueling stations for electric cars to meet customer demands.

8. Electric Cars are More Efficient With Less Pollutants

Eighty percent of the energy in an electric car goes toward powering the vehicle, while only 14-26 percent of the energy used by a petrol car does so. Additionally, electric cars introduce no pollutants, while petrol vehicles produce nitrous oxide, particulates and many other air pollutants.

Clearly, there is much we can learn about electric cars. Are you in the market?

This is What Your Body Will Do in the Next 30 Seconds (Video)

30 seconds might sound like nothing! But in the time it takes you to walk to the kitchen for a glass of water, your body is hard at work. Compiled from a range of scientific studies, BuzzFeed presents an impressive and surprising video on exactly what the human body does in the span of just 30 seconds. Some of our favorites…

In 30 seconds, your body will (on average):

  • Produce 0.3 grams of carbon dioxide
  • Generate 100 watts of energy
  • Produce 72 million red blood cells

Watch the video to find out more!

The human body is full of surprises. Did you know that everyone has a unique “tongue print” similar to a fingerprint? Or that our stomach lining replaces itself every 3 to 4 days? Give it up for the body – doing so much behind the scenes while our minds can wander!
