Yes, there's no claim of free energy or perpetual motion here. The author even discusses approximately how efficient the charging is in the video.

Energy use is proportional to the revenues gained from mining. Revenues are based on the block coinbase reward and transaction fees from transactions (txns) included in the block. The coinbase reward is currently a large majority of mining

Engines combustion is designed to occur as a propagating flame front in the cylinder initiated by the spark plug. Great efforts are made to ensure that this is precisely what happens. The alternative is a detonation, i.e. engine knocking.

I would not consider it a solution to mistrust, but rather a way to obviate it altogether. Bitcoin is simply a way to achieve consensus about value that is secure and decentralized. Many people consider it a currency, and certainly that is

Simple: most people charge at night. Sure, fast charging will add some day-time demand, but it's not much. Cheap night-time pricing keeps the charging demand off-peak. More even demand curves make generation more economical. It becom

Heck, even $40 true-wireless earbuds are now quite decent. They're reliable and sound quality is perfectly fine for what I want from it. Considering the tiny batteries make these disposable items, it's pretty compelling.

That strikes me as a bad-faith interpretation of the history of this issue. The reason for belief in the protective effect of alcohol consumption comes from data, not corporate propaganda. Many observational studies, conducted by a wide va

Magsafe seems less an issue now. With a true 'all day' battery, you'll probably only plug it in at a desk where tripping or knocking things over isn't an issue. While travelling, you just charge it at night or when you

Bike chain teeth do not have straight sides or a convolute profile. They are wedges that act as ramps for the rollers. As the chain wears, it is no longer possible for the rollers to all sit at the base of the teeth. Instead, to account

The Virgin Islands and Anguilla are a big problem for a PR launch site. Even commercial shipping/fishing activity downrange can present a big problem for launches, let alone populated areas. The lower latitude is a minor help, but it&

Because RNA is not a stable molecule. At lower temperatures, it's less likely for a given bond to reach the Gibbs free energy of activation, thus preventing degradation. In a biological context, the vast majority of RNA use falls with

You can, and indeed many direct-drive hub systems include this, but it's not a range issue. It's more to save some brake wear. In a 'best case' scenario of many steep hills, such a system will extend range perhaps 5%.

I genuinely cannot see how anyone can even consider that anything less than 90% of new vehicle sales will be electric in 10 years. The economics are so overwhelming .. it's not a prediction anymore, it's just reality. There are

An electric airliner would be able to operate at much higher altitudes, and thus much more efficiently. Looking only at energy density is naive.

Diffuse light has a tendency to increase yield by decreasing the shading effect on lower leaves, so it largely cancels out. It is also fairly easily to saturate photosites in full sun. Heat/water are more limiting in these contexts.
