Gravity as a source of electricity: this is the idea of Janjaap Ruijssenaars, Dutch inventor of Gravity Energy Ltd, who has just developed a device capable of converting the kinetic energy generated by the fall of a weight into an electric current. Clean and renewable energy, as well as very high efficiency.
Only a prototype for now, but very promising. The system works by unbalancing a weight so that the energy generated by its "fall" is used to activate a piezoelectric generator, which is a device that produces electricity when "compressed". In other words, the weight compresses the generator, which emits electric current.
And apparently a little pressure is enough to generate electricity. Not only that: Ruijssenaars claims that the generator of him could reach the 93% energy efficiency. Which means that nearly all of the gravitational energy would be converted, with just 7% dispersion.
“Can we get energy from gravity? - reads the company's website - It was the question that sparked this invention. The answer was yes […] One unique patented combination of gravity and instability introduced change and paved the way for highly efficient energy generation ”.
93%: a conversion rate thus, if confirmed even on a large scale, appears to be significantly higher than that of other renewable energy sources, such as solar and wind.
Are we facing a turning point in the energy field then? In reality, the device developed by Ruijssenaars is currently only a prototype, therefore far from industrialization.
But its performance seems so high that it prompted investor Jeroen van den Hamer to buy the Dutch company. And we know that business men do not spend money if they do not have the perception that the investment is valid and with excellent earnings prospects.
We hope that they will arrive soon, especially for the environment, we add.
