Digital Trend’s List of the Nine Tech Projects That Changed The World!

Image result for technology history

It goes without saying that both technology and the people who develop it have made great advances more many years.  While the plenitude of  smaller, incremental advances that change our lives in various minor ways (i.e., device and software updates, etc.), there exist at least a few giant projects that essentially transformed our world. From providing a means for humans to travel in space, feats of modern engineering and architecture, and answering questions about our existence, below are three of my personal highlights from Digital Trend’s list of nine of the most important technology-related projects ever.

Meet The K-Boc, the Germ-Killing, Antibacterial Doormat

A recent study from the University of Arizona reveled that almost 500,000 units of bacteria make their home in a new pair of shoes in only two weeks. Even more interesting, these same bacteria can live longer on the shoe’s soles than toilet seats, among many other places. Thankfully, for this issue, there’s a upcoming crowdfunding project that looks to resolve that issue….at least for when you are returning indoors from being outdoors.

Deepwater Wind’s U.S. Offshore Wind Farm Proposal Stores Powers using Tesla Powerpack Batteries

According to a story from Bloomberg, energy supplier Deepwater Wind issued a proposal (one of many from other bids) for a new offshore renewable wind power plant near Massachusetts that would use Tesla’s commercial storage batteries, called Powerpacks, to store energy until it’s needed. Their plan includes the construction of a production facility with 144-megawatt capability build off the coast with the Tesla Powerpacks storing wind-generated energy with a 40-megawatt storage capacity at peak production times, and hold it in reserve for peak demand hours.

The MucoJet, for Needle-Free, Painless Vaccinations…

Injections for vaccinations, while saving the lives of millions of people from common sicknesses and diseases, are still pretty painful; particularly for younger children who are most at risk of diseases. That might change within the next ten years, thanks to researchers in Dorian Liepmann’s lab at the University of California, Berkeley, who’ve developed the MucoJet. The creation is a needle-free, pill-sized, 3D-printed device that shoots a stream of vaccine into the tissue of the cheek, making vaccinations practically painless.

Here’s That Caffeinated Soylent You’ve PROBABLY Heard About…

I can assure you that this Soylent product is in NO WAY people-related.  Anyway, this is called Coffiest, mainly because it’s more coffee-er than the coffee we’re familiar with. This comes from the people at Soylent, known for their delivery service that provides meal-replacing, soy and algal oil-based nutrient products similar to their existing liquid offerings, with a key new addition. While Coffiest is made for the Soylent faithful who want that little extra kick in the morning, it comes with a coffee flavoring of light roast coffee with “a hint of chocolate,” according to Soylent themselves.

Apparently, the added java adds a kick of caffeine to the drink as each bottle contains the equivalent of a 16-ounce cup of coffee. The mixture also includes the amino acid l-theanine, which is said to help reduce caffeine-induced jitters that I know I’M VERY familiar with. Plus, each bottle has 400 calories, which is roughly 20-percent of the recommended daily nutritional requirements, and DOES NOT INCLUDE animal products or byproducts. Twelve bottles of Coffiest come at $37 a month, and is now available through Soylent’s website.

This is Probably The BEST WAY to Erase a Hard Drive…

Even though the U.S. Department of Defense have their recommendations and standards for formatting old drives, this method from YouTube channel __ makes the DOD’s method look amateurish. This method can be called the “Molten Copper Overwrite™,” which ensures total and COMPLETE destruction of the hard disk drive, making it nothing more than an unusable block of metal, or a nice modern art-inspired paper weight. One thing for sure, any ne’er-do-well will never — and The PractitioNERD means NEVER —  be able to get access to the scorched ones and zeros on the disc. What’s even better is that this method also — and unsurprisingly — works on solid state drives, CDs, magnetic tape, people* (like THIS GUY) and portable drives, so NOW I can securely prevent anyone from finding embarrassing high school pictures and assignments from my old ZIP disks…

*Seriously, DO NOT POUR Molten Copper on People; C’mon y’all…

You’ll Need to Head to Sweden to Ride the First Electric Highway…

Scania and the Swedish government have taken a huge step toward renewable energy with the opening of their first stretch of Electric-Highway, also known as the e-Highway.  After working for years on hybrid tractor-trailer trucks, Scania finally developed a WORKING system.  This was accomplished by attaching a pantograph on top of the trucks, allowing the trucks to be easily attached/detached to electricity lines running along one lane of the highway.
