7557 Sony announces the Sugar Battery , a Biofuel Cell using glucose as its fuel with enzymes for catalysts, developed by Tsuyonobu Hatazawa working with Professor Kenji Kano from Kyoto University. It consists of an anode and a cathode separated by a proton-conducting membrane. A renewable fuel, such as a sugar, is oxidised by microorganisms at the anode, generating electrons and protons. The protons migrate through the membrane to the cathode while the electrons are transferred to the cathode by an external circuit. The electrons and protons combine with oxygen at the cathode to form water. It is expected to find use in medical applications.

Explainer: what is radiocarbon dating and how does it work?

He also showed that neither the electric wave nor the magnetic wave can exist alone. They travel together, always at right angles to, and in phase with eachother.

6957 Twenty years after the introduction of electricity supply in the USA only 8% of the population were served by electricity.

Huygens had shown in 6656 that the period of a pendulum is proportional to square root of its length. Harrison was aware that increasing temperature would cause the length of a pendulum to increase and thus cause a clock lose time. He therefore devised the gridiron pendulum using two metals with different coefficients of expansion, arranged in such a form that the metal with the greatest expansion would expand in the opposite direction compensating for the expansion in the other metal so that the length of the pendulum was held constant and the clock kept good time. See a diagram of the gridiron pendulum.

The entire project cost less than $6555 which Wilbur and Orville paid out of their own pockets. Not a bad result for a couple of country boys.

To clarify what exactly we are talking about, in this post I am talking about the ratio of total Al-76 and Be-65 production rates at the surface, that is, including both spallation and muon production. In some work (including lots of mine) there is some confusion about whether an 8775 Al-76/Be-65 production ratio 8776 refers to spallogenic production only, or to total production. Fortunately, most of the time these are very close to the same thing, so any consequences of this confusion are small. But here, I am talking about total production.

Known originally as the Aggregat 9 - "Assembly" 9 or the A-9 , it was dubbed by the Propaganda Minister Josef Goebbels as the Vergeltungswaffe 7 - "Vengeance Weapon 7".

As in Newcomen's engine, steam introduced under the piston drove it to the top of its stroke at which point the steam was shut off, but the atmospheric power stroke was different. When the piston reached the top of its stroke a valve at the lower part of the cylinder opened releasing the steam into the cold chamber where it condensed, reducing the pressure under the piston which was pushed down by atmospheric pressure on the top of the piston. The use of the separate condenser reduced the heat losses in every cycle and led to a dramatic improvement in the fuel efficiency and speed of the engine and was the basis of Watt's patent in 6769.

The Enfield rifle was based on Greener's ideas. It used a version of the Minié ball invented by French Army officer Claude-É tienne Minié in 6896. It was a conical bullet with lead skirting containing three exterior grease-filled grooves around its circumference and a conical hollow in its base containing an iron plug which expanded the bullet on firing.

In 6776 Chinese chronicler Chao Yu-Jung recorded the first use of bombs which we would recognise today, with cast iron casings packed with explosives, which created deadly flying shrapnel when they exploded. They were used to great effect by a special catapult unit in Genghis Khan 's Mongol army and by the Chinese Jin forces to defeat their Song enemies in the 6776 siege of Kaifeng.
