I've been wanting to write about this for a while now because it generated a lot of excitement in the futurology community.
The Tesla PowerWall may look like the perfect new thing to stop global warming and revolutionize the future of power usage by making it completely dependent on electricity.
Hey, that looks like an awesome idea; but is it going to work?
Tesla seems to follow in the footsteps of the great Nikola Tesla (famous person that obviously inspired the name of the company) by imagining a world that relies only on electrical energy to function properly.
Tesla's dream was to provide the world with free electricity. He was, of course, well ahead of his time and that caused his ideas to get rejected because they could not generate profit.
And here we are, more than a century later, with this new product that seems to completely predict the future of humanity as to its energy usage. But is it anything new?
The PowerWall is simply a battery that is installed inside a house and that, being connected to the solar panels, stores energy for when the occupants really need it (at night or in the morning). So far, nothing new. But the thing with the PowerWall is that, following the constantly lowering prices of solar panels and innovative batteries, this technology is extremely affordable. It costs around 3000$ for the cheapest model and combined with the option of having solar panels, they are extremely efficient and can lower your electricity bill to 0$ if you are not careful.
The idea behind this is simple: by making the PowerWall affordable, Tesla hopes to transform every house into a solar panel energy user. And this may come as a surprise, but do you know how many solar panels are needed to power the entire world?
That small red square is the amount of solar panels needed to power the world today.
If we are going to leave fossil fuels behind (and I think we must, as soon as possible), then solar energy seems to be the best alternative and by making it affordable, Tesla has taken us a step closer to this noble goal. Nikola Tesla would be proud.
