Biofuel cells could power electrical gadgets

Green Cars News

Scientists are developing a way to use nature’s own power stations, mitochondria, to convert organic matter into energy. According to the BBC, scientists at St Louis University in Missouri, US have developed a prototype cell, similar to the ones our own bodies, which can convert almost anything into energy.

Drones with Legs Can Walk, Hop, and Jump into the Air

As the paper summarizes, “although jumping take-off requires slightly higher energy input, it is the most energy-efficient and fastest method to convert actuation energy to kinetic and potential energies for flight.” Jumping, on the other hand, ends up being about ten times more energy efficient overall than a standing takeoff.

Bezos Bucks? Get Ready for Corporate Digital Currency

Customers could convert U.S. dollars into amazons—and, at least for the time being, they could convert them back, on demand, at a 1:1 exchange rate, perhaps for a small fee. The amazons could be converted frictionlessly into dollars. I like Bezos bucks or BBs , but that might be a bridge too far, even for Jeff Bezos.)

Get The Z Factor With An RC2014 This is the one entry in our retrocomputing gift guide I haven't tried myself: I've never been a Z80 guy, being more influenced by the 6502-based BBC Microcomputer than the Z80-based ZX Spectrum, which were the two most popular British-designed computers I had access to in the 1980s.

In effect therefore, the more energy convertion stages there are the less efficient the process is. Whenever we take a source, convert it and then use it to generate electricity (usually steam generation) or use it to run an internal combustion engine it seems counter intuitive efficiency wise. The closest to that source is solar.

A receiving apparatus converted the signals into light, to reconstruct the image. As the transmitting disk rotated, the photoelectric cell detected the change in brightness coming through the individual lenses and converted the light into an electrical signal. Each line would be encoded as an electrical signal.
