Get an unlocked iPhone X for 750

first_imgRemember when the iPhone X debuted in late 2017? “A $1,000 phone?! It’ll be a cold day in…” Ah, so you do remember.Today only, and while supplies last, Best Buy has the unlocked Apple iPhone X (64GB) for $749.99 shipped when you choose the “activate later” option. That’s $250 off and one of the best iPhone X deals I can recall seeing.See it at Best BuyAs you’ve probably noticed on the product page, you also have the option of getting the phone for $699.99 — but that’s if you activate it with AT&T, Sprint or Verizon. My advice: Buy it outright, then take it to a carrier with cheaper rates. You’ll save in the long run, and you’ll have the option of switching carriers anytime you want.The elephant in this particular room is the iPhone XR, which also runs $750 for the unlocked 64GB model. Personally, I think they’re both great phones, but there are a few key differences. Post a comment $949 The iPhone X has a 5.8-inch OLED screen and the XR has a 6.1-inch LCD. They’re both gorgeous. I’d say size is the only factor that’s changed. The iPhone X has dual rear cameras, which allows for real 2x optical zoom and some sweet bokeh (portrait effect) photography. The XR’s single rear camera, meanwhile, is limited to digital zoom, though its software-based bokeh mode is surprisingly good.The XR also has slightly better battery life and support for dual-SIM technology. Beyond all that, the two are pretty darn similar. Read CNET’s iPhone X review (“Still a contender”) and iPhone XR review (“The best iPhone value in years”) to learn more.

Suicide attack kills 27 Iran elite Revolutionary Guards

first_imgMap or Iran locating the city of Zahedan. Photo: AFPA suicide bomber killed 27 members of Iran’s elite Revolutionary Guards on Wednesday, state media said, in a southeastern region where security forces are facing a rise in attacks by militants from the country’s Sunni Muslim minority.The Sunni group Jaish al Adl (Army of Justice), which says it seeks greater rights and better living conditions for the ethnic minority Baluchis, claimed responsibility for the attack, the semi-official Fars news agency reported.The heavy losses among Iran’s premier military force prompted a senior Revolutionary Guards commander to issue a warning to the country’s foes.“Our response in defence of the Islamic Revolution will not be limited to our borders,” Ali Fadavi was quoted as saying by Fars.“The enemies will receive a very firm response from the Revolutionary Guards like before.” He did not specify which enemies or what actions Tehran would take.In the past Iran has accused its regional rival, Sunni Arab Saudi Arabia, of supporting Sunni separatist groups who have attacked its security forces. Riyadh has denied the charges.Iran’s Shi’ite Muslim authorities say militant groups operate from safe havens in Pakistan and have repeatedly called on the neighbouring country to crack down on them.A suicide bomber driving a vehicle laden with explosives attacked a bus transporting members of the Guards, the force said in a statement. Thirteen people were wounded.A video posted by Fars showed blood and debris at the site of the attack on a road in a volatile area near the Pakistan border where militants and armed drug smugglers operate.The bus was turned into a twisted pile of metal, a photo published on Fars showed. Reuters could not independently verify the image.While Sunni militant groups are not regarded as a major threat, the attack dealt a fresh blow to Iran’s security establishment, which has often said it can repel any threat no matter how big, even from the United States and its ally Israel.Military Might And Business InterestsThe assault in impoverished Sistan-Baluchistan province – among the worst ever on the Guards – illustrated that Iran’s elite force, which answers directly to Supreme Leader Ayatollah Ali Khamenei, can be vulnerable to guerrilla-style operations.The Guards’ estimated 125,000-strong military, with army, navy and air units, has acted as the sword and shield of Shi’ite clerical rule in Iran since its 1979 Islamic Revolution.The force also operates outside of Iran’s borders in countries such as Iraq and Syria where it works with proxies to promote Tehran’s interest. It runs a business empire in Iran worth billions of dollars.“The self-sacrificing military and intelligence children of the people of Iran will take revenge for the blood of the martyrs of this incident,” Fars quoted Foreign ministry spokesman Bahram Qassemi as saying.Iran’s Guards fired missiles at Islamic State militants in Syria in 2017 and 2018 after the group claimed responsibility for two attacks in Tehran and Ahvaz. In 2018, the Guards launched missiles at an Iranian Kurdish armed opposition group in northern Iraq.Wednesday’s violence comes during a month in which Iran has been commemorating the 1979 Islamic Revolution which swept the US-backed Shah from power. Tehran showed off ballistic missiles in defiance of US efforts to curb its military power.Iranian foreign minister Mohammad Javad Zarif appeared to blame the United States for the attack, citing a US-sponsored conference in Warsaw aimed at rallying support to further isolate Iran.On Twitter he asked: “Is it no coincidence that Iran is hit by terror on the very day that #WarsawCircus begins?”Iran had enjoyed relative stability compared to Arab neighbours who have grappled with political and economic upheaval touched off by popular uprisings in 2011.But economic hardships fuelled by US sanctions have triggered waves of protests that sometimes call for Iran’s clerical leaders to step down.Twelve members of the Guards were among 25 people killed last autumn by gunmen on a military parade in the city of Ahvaz in the southwest. The Sunni Islamic State and an Arab separatist group both claimed responsibility.Jaish al-Adl emerged as the main armed opposition movement in the southeast after members of another Sunni group, Jundullah, joined it after their leader was captured on a plane in 2010. He was tried and executed.last_img read more

HydrogenWindNuclear Plant in Ontario Not Currently Worthwhile Study Shows

first_img Explore further Bruce Power – Canada’s first private nuclear generating company – is considering including a hydrogen storage and distribution component to go along with a large scale wind farm, all presently sharing the main electrical transmission line in Bruce County, Ontario. The province’s first commercial wind farm, Huron Wind, is located on the shore of Lake Huron. Its five wind turbines provide a maximum output power of 9 MW. Additional large scale wind farms are located close by, using the same transmission lines.Bruce Power’s nuclear power plant, located about 250 km northwest of Toronto, consists of six reactors. Together, the reactors generate a total output power of 4,830 MW, which supplies more than 20% of Ontario’s electricity.Using hydrogen as a storage and distribution method for the electricity generated by the wind farm and nuclear plant from the same region could have several potential benefits. When the cost of electricity is low, for example, the company could store part of its electricity production as hydrogen, and then sell it back to the electricity market when the price increases. Similarly, electricity could be stored as hydrogen when there is not enough line capacity to transfer it all at once. In periods of low winds, hydrogen storage could help make up for the variability and in periods of high winds and constrained transmission capacities, hydrogen could be used to store the electricity. In the future, the hydrogen itself could be sold to a hydrogen market, which could be more profitable than selling it back to the electricity market. However, costs of the initial investment, production, and operation won’t be matched by the profit solely from storing electricity as hydrogen, according to the study by Gregor Taljan and Gregor Verbič from the University of Ljubljana, Slovenia, and Claudio Cañizares and Michael Fowler from the University of Waterloo, Ontario. Even with an optimistic hydrogen production efficiency of 60% through electrolysis, the researchers’ evaluation shows that the electricity stored as hydrogen would need to be sold to the electricity market at a high price that rarely happens in order for the scheme to be profitable. As the researchers demonstrate, the selling price of electricity would need to be about four times the buying electricity price for the hydrogen system to profit from storing electricity.

A recent case study on using hydrogen to store the electricity generated by a mix of wind and nuclear power in Ontario, Canada, has shown that the hydrogen addition won’t be worth the cost, at least not at the current state of hydrogen technology development.

On the other hand, it might be economically acceptable to produce hydrogen from electricity at advantageous electricity/hydrogen prices. Furthermore, hydrogen is shown to be a highly favorable option when there are electricity transmission constraints in the area, limiting sales of electricity of a power producer.”As the researchers explain, hydrogen storage might be an economically feasible option for storing electricity in times of insufficient electricity transmission line capacities, which would otherwise be dumped. This could be especially true in cases where the upgrade of transmission systems is not an option due to various reasons (such as remote location, resistance of local population, etc.).The study also showed that a hydrogen sub-system for producing hydrogen could be profitable if there is sufficient hydrogen demand. For instance, transportation applications (such as cars, trains, and planes) could provide a market for buying hydrogen produced by a mixed wind-nuclear plant. “Hydrogen production might become profitable when the Hydrogen Economy becomes fully mature, i.e. when the demand, and correspondingly prices, for hydrogen increases (expected mainly from the transportation sector),” Taljan said. “This might happen when the prices of fossil fuels rise as a result of many different possible factors (e.g. shrinking reserves, higher demand, political instabilities, CO2 emissions trading schemes). In this scenario, hydrogen might become a real fossil fuel substitute option which will drive up the hydrogen demand and prices, making the hydrogen production a lucrative business. “In this context, it is also important that research into hydrogen production, storage, transmission, distribution and consumption components ‘wins the battle’ with the electron economy, where the energy carrier is considered to be electricity. Those two economies compete in many different areas, such as efficiencies, durability, and prices. Currently, hydrogen is advantageous in terms of higher energy density and durability but still lags in efficiencies.”The team’s investigation into the feasibility of hydrogen is further elaborated in two other recent studies. “Hydrogen storage for mixed wind–nuclear power plants in the context of a Hydrogen Economy,” which is published in the International Journal of Hydrogen Energy, deals with how the excess oxygen and heat utilizations would improve the economics of hydrogen systems primarily designed for storing of electricity. The second study, “Study of Mixed Wind-Nuclear-Hydrogen Power Plants,” which is going to be presented at this year’s North American Power Symposium in Calgary, demonstrates that hydrogen is not economically feasible for the sole purpose of storing electricity, in spite of residual heat and oxygen utilization, and based on current hydrogen production and utilization technologies.More information: Taljan, Gregor; Cañizares, Claudio; Fowler, Michael; and Verbič, Gregor. “The Feasibility of Hydrogen Storage for Mixed Wind-Nuclear Power Plants.” IEEE Transactions on Power Systems, Vol. 23, Issue 3, August 2008.Copyright 2008 PhysOrg.com.
