Qatari non-profit organization Gulf Organization for Research and Development (GORD) launched a low emissions car at the 2012 United Nations Climate Change Conference (COP 18) in Doha. The car was designed and developed in Qatar.

Revealed during a press conference at the Qatar National Convention Centre, the car in addition to an internal combustion engine, includes an automotive thermoelectric generator designed to capture waste heat to produce hydrogen. GORD expects the heat waste collecting system to be compatible with any gasoline or compressed natural gas car.

GORD chairman Dr Al-Horr summarised the key concepts of the invention in a statement saying, “Our car produces electricity at no cost by capturing thermal waste energy, reducing costs and eliminating the need for an external source of electricity. Also, bulky compressed-hydrogen cylinders are a thing of the past, as our concept accomplishes the production of hydrogen by using water through fuel cells integrated within the car.”

Most of the energy in Qatari vehicle comes from the the car’s gasoline tank, supplemented by a thin film photo-voltaic panel on the roof. Normally in a combustion engine, chemical energy stored in a fuel, such as gasoline, is converted into heat energy through combustion. This heat energy is then converted into mechanical energy, manifested as an increase in pressure in the combustion chamber due to the kinetic energy of the combustion gases. The kinetic energy of these combustion gases are then converted into work; because of the inefficiencies in converting chemical energy into useful work, internal combustion engines have a theoretical maximum effiecincy of 37% (with what is achievable in day to day applications being about half of this). Of the chemical energy in the consumed fuel used by an internal combustion engine 40% is dissipated as waste heat. However, the Qatari vehicle uses a thermoelectric generator to convert this waste heat into electricity. Such generators are used in space vehicles, and produce electricity when thermoelectric materials are subjected to a temperature gradient, the greater the gradient the greater the amount of electrcity produced. In the GORD vehicle the electricity produced is used to electrolyse potable water to produce hydrogen which can be introduced into the vehicle’s existing fuel system.

The researchers showed that the heat waste collection engine caused a decrease in the car’s emissions, including a decrease of carbon monoxide and nitrous oxide emissions by more than 50%, the fuel efficiency increasing by 20%. On its website, GORD said that the heat waste collector engine is universal, “Any car can be adapted to accommodate the system as it doesn’t alter any electro-mechanical systems”.

A man shot and killed a Broward County Sheriff’s Office police dog in Miami Beach after a two-county chase in Florida early Thursday morning.

The shooter, Delvin Lewis, 27, was firing shots at his girlfriend during a domestic dispute in Oakland Park. When police arrived, the suspect got into his car and fled, engaging roughly 20 cruisers in a 30-mile chase which ended near Mount Sinai Medical Center’s emergency room in Miami Beach. An exchange of gunfire followed in which Lewis reportedly killed the dog. ER doctors tried to save the animal but it was too late.

The shooter was also struck and has been taken to Jackson Memorial Hospital where he remains with no life threatening injuries.

According to a Mount Sinai spokeswoman hospital facilities are now accessible after the authorities locked down the area for three hours following the shooting.

Lewis has been arrested 26 times by Florida authorities including one in July 2003 in which he injured a police dog striking him repeatedly on the head with a cellphone.The suspect has been charged with aggravated assault with a motor vehicle on a law enforcement officer, aggravated fleeing and eluding, resisting an officer with violence and principal in the death of a police dog.

Hitting a police dog is a third-degree felony punishable by up to five years in jail, while killing a police officer is a capital offense which can lead to the death penalty.

Miami-Dade Police Department is handling the investigation which involves Broward Sheriff Office and Miami Beach police.

Lewis has been in and out of jail since 2000 and had been arrested for domestic battery in 2000 and 2004, when he beat a pregnant woman.

The dog, whose name was Oozi, was a 7-1/2 years old Belgian Malinois assigned to BSO’s Cooper City district. He was trained in narcotics and helped in hundreds of arrests in his career, including 35 this year.

Oozi and his partner, Deputy Gerald Wengert, were named BSO’s Employees of the month in May for their role in the apprehension of three burglary suspects.

While nearly all coverage of the 2008 Presidential election has focused on the Democratic and Republican candidates, the race for the White House also includes independents and third party candidates. These parties represent a variety of views that may not be acknowledged by the major party platforms.

Wikinews has impartially reached out to these candidates, throughout the campaign. We now interview independent Presidential candidate Frank Moore, a performance artist.

An advert by fast food restaurant Burger King has been banned from British television over claims that it is misleading. The campaign for the new TenderCrisp chicken burger received two complaints over the fact that the burger appears significantly larger on the advert than in real life.

The Advertising Standards Authority (ASA) investigated the complaints and purchased three burgers from a Burger King restaurant. They reported that both the thickness and the height were “considerably less” than in the advertisement.

The ASA also commented on the actor, stating, “[w]e also examined the size of the burgers in the hands of an average-sized man and considered that they did not fill the hands to the same extent as the burger featured in the advert. We concluded that the visuals in the advert were likely to mislead viewers as to the size and composition of the product.”

Burger King responded to the complaints, saying that the advert needed to make all the ingredients in the product clearly visible. Despite the company’s defense, it has been ruled that the advert will not be shown again in its current form.
