Neuralink Corp. is an American neurotechnology company that has developed, as of 2024, implantable brain–computer interfaces (BCIs). It was founded by Elon Musk and a team of seven scientists and engineers.
Human power is the rate of work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans. World records of power performance by humans are of interest to work planners ...
The eyed needle — a sewing tool that first appeared around 40,000 years ago — might be hiding important clues about the beginnings of fashion, a new study finds.
That percentage grew to 32% in 1996, 50% in 2000, 80% in 2007 and 94% in 2011. [6] [7] The Taiwanese ODMs have since lost some market share to Chinese ODMs, but still manufactured 82.3% of the world's laptops in Q2 of 2019, according to IDC.
Electricity production. Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power.

A human microchip implant is any electronic device implanted subcutaneously (subdermally) usually via an injection. Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number that can be linked to ...
If the final energy delivered for consumption is E and the EROI equals R, then the net energy available is E-E/R. The percentage available energy is 100-100/R. For R>10 more than 90% is available but for R=2 only 50% and for R=1 none. This steep decline is known as the net energy cliff.
