What was the original price for a replacement battery from the SK8 developer?
$99
Title: 1973 oil crisis
Passage: This contributed to the "Oil Shock". After 1971, OPEC was slow to readjust prices to reflect this depreciation. From 1947 to 1967, the dollar price of oil had risen by less than two percent per year. Until the oil shock, the price had also remained fairly stable versus other currencies and commodities. OPEC ministers had not developed institutional mechanisms to update prices in sync with changing market conditions, so their real incomes lagged. The substantial price increases of 1973–1974 largely returned their prices and corresponding incomes to Bretton Woods levels in terms of commodities such as gold.
Title: SK8
Passage: SK8 (pronounced "skate") was a multimedia authoring environment developed in Apple's Advanced Technology Group from 1988 until 1997. It was described as "HyperCard on steroids", combining a version of HyperCard's HyperTalk programming language with a modern object-oriented application platform. The project's goal was to allow creative designers to create a complex, stand-alone applications. The main components of SK8 included the object system, the programming language, the graphics and components libraries, and the Project Builder, an integrated development environment.
Title: 1973 oil crisis
Passage: OPEC soon lost its preeminent position, and in 1981, its production was surpassed by that of other countries. Additionally, its own member nations were divided. Saudi Arabia, trying to recover market share, increased production, pushing prices down, shrinking or eliminating profits for high-cost producers. The world price, which had peaked during the 1979 energy crisis at nearly $40 per barrel, decreased during the 1980s to less than $10 per barrel. Adjusted for inflation, oil briefly fell back to pre-1973 levels. This "sale" price was a windfall for oil-importing nations, both developing and developed.
Title: Gold
Passage: The price of gold is determined through trading in the gold and derivatives markets, but a procedure known as the Gold Fixing in London, originating in September 1919, provides a daily benchmark price to the industry. The afternoon fixing was introduced in 1968 to provide a price when US markets are open.
Title: Chevrolet Volt
Passage: The Chevrolet Volt concept car debuted at the January 2007 North American International Auto Show, becoming the first-ever series plug-in hybrid concept car shown by a major car manufacturer. The Volt concept vehicle had four doors with a rear liftgate and seating for four passengers. This was a significant change in design when compared to the General Motors EV1 of the 1990s, which only seated two to reduce weight and to make the necessary room for the lead-acid battery pack. The top speed was also increased on the Volt, from the electronically limited 80 miles per hour (130 km/h) to 100 miles per hour (160 km/h). The battery pack size was reduced, from about 10.6 cu ft (300 L) in volume in the EV1, to 3.5 cu ft (100 L) in the Volt.General Motors' then-Vice-Chairman Robert Lutz said the two-seater sports car being developed by Tesla, the Tesla Roadster (2008), and the rapid advancement of lithium-ion battery technology inspired him to push the carmaker to develop the Volt after the 2006 Detroit Auto Show, overcoming internal opposition. Lutz's initial idea was to develop an all-electric car, but Jon Lauckner, General Motors Vice President for Global Vehicle Development, convinced him that to avoid an expensive battery, range anxiety concerns, and lack of public charging infrastructure, they could use a smaller battery pack with a small gasoline engine driving a generator acting as a backup to extend the range, but without a mechanical connection between the gasoline engine and the drive wheels, so it would be a pure electrically driven vehicle without many of the limitations General Motors learned from the EV1 experience.
Title: Anti-aircraft warfare
Passage: The basic air defence unit is typically a battery with 2 to 12 guns or missile launchers and fire control elements. These batteries, particularly with guns, usually deploy in a small area, although batteries may be split; this is usual for some missile systems. SHORAD missile batteries often deploy across an area with individual launchers several kilometres apart. When MANPADS is operated by specialists, batteries may have several dozen teams deploying separately in small sections; self-propelled air defence guns may deploy in pairs.
Title: IPod
Passage: Apple announced a battery replacement program on November 14, 2003, a week before a high publicity stunt and website by the Neistat Brothers. The initial cost was US$99, and it was lowered to US$59 in 2005. One week later, Apple offered an extended iPod warranty for US$59. For the iPod Nano, soldering tools are needed because the battery is soldered onto the main board. Fifth generation iPods have their battery attached to the backplate with adhesive.
