“Connecting people.” Do you still remember this slogan made by Nokia several years ago? Technology always comes from what people want and need. What things can you imagine to make them “smart”? A smartphone, a smartwatch, smart shoes, or smart home appliances. Have you ever thought about smart … “surfboard”?!

The world is filled with social media; hence, many people don’t want to be disconnected anywhere and anytime. They check their messages, twitts or Facebook feeds all the time even when doing outdoor activities such as rock climbing, kayaking and surfing. Does that really annoy you when doing these exercises but you are unable to check your messages? If you are surfing lovers. Don’t worry, Samsung starts working out with practical methods at your positions- “Samsung Galaxy Surfboard.”

Samsung invited world champion Brazilian professional surfer, Gabriel Medina, to endorse this smart surfboard. The concept of this board is that surfers are “disconnected” when they are alone in the ocean. The board is designed with a built-in LED screen that can display twitts, text messages, the guidance from your coach (it seems you can’t escape anywhere…), and the real time information on the wind and the water conditions. Once you insert your Galaxy S7 into the board, the board becomes smart. It seems to be a perfect board which all surfers need it. Perhaps the next step of Samsung is to design a smart snowboard.

However, is this smart surfboard necessary? It is a question plenty of people are asking. We have been obsessed with Internet-connected devices for 24 hours a day. It is just over the top. Can’t we just focus on what we are doing for just one second? Chris Davis, a famous baseball player, wrote “sorry, not a big fan of this at all” on his Twitter. But Samsung says the concept is aimed at professional surfers who spend hours alone in the ocean.

Although the smart surfboard is a concept, we should enjoy what we are doing rather than being obsessed with a smart device. Therefore, “is smart necessary?” is the issue we have to think about.

“Blue” Energy

“Green” is common criteria when speaking of sustainable energy. The popular technologies are solar power and wind turbine but they heavily depend on the weather, which is variable. Over decades and decades, scientists keep searching for the most sustainable and eco-friendly power to develop sustainably. What if “Green” is not the only option of sustainable power?

“Blue” is the power. Blue energy sustains all seasons and the technology cost is relatively inexpensive. It is estimated to be plentiful to meet all human beings’ needs. This technology is so called “Osmotic power or Salinity gradient power.” The blue energy seems to be resourceful but the critical part is how we can find an effective way to tap it.

Let us get to know more about “Osmotic.” Imagine that there is a beaker divided by a semi-permeable membrane with two different concentrations of dissolved substance like salt. The concept is that when different concentrations exist, both sides of the water will naturally pass through the semi-permeable membrane to reach balance. This flow of water across the membrane builds up pressure on one side that can be used to drive turbines and generator power. This concept was first proposed by a British engineer, R E Pattle in 1954. Blue energy seems to be perfectly sustainable; however, the first osmotic power plant was conducted in Tofte, Norway, in 2009 by the company Statkraft, with a generating capacity of 4kW, which can be consumed to run only one home use coffee machine. Statkraft closed the plant in 2013 because it was difficult to make both ends meet.

The good news is, École polytechnique fédérale de Lausanne (EPFL) researchers have developed a system that generates electricity from osmosis with unparalleled efficiency. The related papers are posted on “Nature.” The power density of this newly-optimized osmotic way generates 1 MW/  (equals to 1  thin membrane can support 50,000 light bulbs). Even in a sufficient desert area, the power density of solar panels can barely reach 200W/ . According to one estimate, placing this new system at every estuary on the earth will generate almost 2 TW electricity (equals to 2,000 nuclear power plants) every single day.

Not only “Green” but also “Blue” energy would be our power solution. Let’s expect how mixing water can create electricity. What do you think about “Blue” energy? Would that be our energy solution?
