Kim Zolciak-Biermann claims daughter Ariana, 18, is 'dying' to get lip fillers

  Kim Zolciak-Biermann claims daughter Ariana, 18, is 'dying' to get lip fillers Kim Zolciak-Biermann claims her 189-year-old daughter Ariana is "dying" to get lip fillersAccording to Kim, her 18-year-old daughter "can't wait" to get lip injections. The reality star recently discussed Ariana re-wearing her Playboy bunny costume for Halloween to Entertainment Tonight, adding that, "I think she's been dying to be 18 so that she could do something like that or do her lips or do whatever - she's been dying to be 18.

A UK company is using non-recyclable plastics and other waste to generate electricty and hyrdogen.

UK company Powerhouse Energy wants to turn the current plastic deluge into an opportunity by producing energy from non-recyclable plastics Yet countries are forging ahead with the technology: Japan aims to have 200,000 hydrogen cars on its roads by 2025, served by 320 fueling stations.

Britain produces about 5 million metric tons of plastic waste every year, but less than a third of that is recycled. Roughly half ends up in landfills.

UK company Powerhouse Energy wants to turn this plastic deluge into an opportunity by producing energy from non-recyclable plastics and other waste.

Powerhouse Energy has developed a process where it shreds the waste and then heats it to around 1,800 degrees Fahrenheit to produce syngas — a mixture of hydrogen, methane and carbon monoxide. Syngas can either be burned to produce electricity, or the hydrogen can be separated out to power fuel cells in vehicles.

Cars singer Ric Ocasek died of heart disease, natural causes: NYC medical examiner

Cars singer Ric Ocasek died of heart disease, natural causes: NYC medical examiner Cars frontman Ric Ocasek died from hypertensive and atherosclerotic cardiovascular disease, the city’s medical examiner said Monday. Pulmonary emphysema was also a contributing factor in the 75-year-old singer’s death, the medical examiner added. The “You Might Think” rocker was found in bed in his E. 19th St. home by his estranged supermodel wife, Paulina Porizkova, about 4 p.m. Sunday , police sources said. Police said at the time that they did not suspect foul play. The Cars sold more 23 million albums in the U.S. alone in their heyday, which lasted from 1976 to 1988.

Plastic to fuel projects are beginning to gain traction in the energy industry, with rising awareness of the prolific environmental damage caused by single-use Plastic -derived fuels are also capable of producing a cleaner burning fuel than traditional sources due to their low sulphur content, considering

Hydrogen fuel cells use a chemical reaction to produce energy , converting hydrogen stored in the vehicle into electricity, while emitting only water vapor. But China has the muscle to change all that should it make hydrogen - powered vehicles a national priority -- the type of turning point the industry

Hydrogen fuel cell vehicles are powered by electric motors, but instead of carrying their energy in a battery pack, they create electricity by combining hydrogen with oxygen from the air in a fuel cell. Water vapor and heat are the only byproducts at the tailpipe.

Hydrogen cars have two big advantages over battery-powered electric vehicles: they can usually drive farther before needing to refuel, and refueling takes only a few minutes, not the hours it can take to charge an electric battery.

"For road transport, hydrogen is the perfect fuel," says David Ryan, CEO of Powerhouse Energy. "For large lorries [trucks] and buses it is probably the future of clean fuel, because its emission is water."

One downside is that hydrogen fueling stations are few and far between; in the United Kingdom there are fewer than 20. Yet countries are forging ahead with the technology: Japan aims to have 200,000 hydrogen cars on its roads by 2025, served by 320 fueling stations.

Why TIME Chose Greta Thunberg as the 2019 Person of the Year

  Why TIME Chose Greta Thunberg as the 2019 Person of the Year TIME's Editor-in-Chief explains why climate activist Greta Thunberg was chosen as the 2019 Person of the Year. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); It began with a story line familiar to every parent of every generation in every corner of the globe: an indignant teenager and a sudden burst of rebellion. It became one of the most unlikely and surely one of the swiftest ascents to global influence in history.

The new technique turns plastic into fuel by mixing it with other materials. What if we could turn them into fuel instead? That 's the ambitious plan of a team of scientists from the University The goal is to break the molecules in the plastic down to their original components -- hydrogen and carbon

A hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power . Hydrogen vehicles include hydrogen - fueled space rockets, as well as automobiles and other transportation vehicles.

Reducing emissions

About three quarters of the world's hydrogen supplies are made from natural gas, a process that produces carbon emissions. But even cars powered this way can reduce carbon emissions by more than 30% compared with conventional vehicles, according to the Union of Concerned Scientists, a US non-profit.

Powerhouse Energy says its own production process emits much less CO2 than using natural gas, giving motorists a significantly greater emissions saving — while using up rubbish that would otherwise go to landfill.

Powerhouse Energy's process is still at demonstration level, but it plans to soon expand to 11 sites in the United Kingdom. It ultimately hopes to have a number of small facilities near cities worldwide, using local waste to provide communities with power and hydrogen. Locating a plant at or close to a hydrogen cell refueling point would reduce the carbon emissions created by transporting the hydrogen.

"The vision is that fuel-cell vehicles can be used in the place of hybrids now — so you might have a fuel-cell car with a battery backup," says Ryan. "But for lorries and buses, the vision is that they could be totally hydrogen fueled. We can provide enough fuel for a day's transportation and then they return to base to refuel for the next day."

Fuel cells make less sense in cars, according to the researcher © Motor1.com/Manufacturer On-location pictures Are hydrogen cars the future or are they more electric cars? Car fans are currently getting into this hair more often on this question. An interesting interview conducted by Wirtschaftswoche with electro and solid-state chemist Maximilian Fichtner in Ulm provides information on energy losses.
