 Electric cars have become more common, but building a commercial electric plane is a different story. Just ask Mohamed Ali, vice president for engineering at GE.  Electric motors behave very differently at altitudes above 10,000 feet,  he says.  They are susceptible to plasma arcing, for example, and much more difficult to manage. Source: GE AviationBut Ali has some good news for the industry. Speaking at the Farnborough International Airshow in July, Ali, together with NASA, announced GE is the first to successfully test high power, high voltage hybrid electric aircraft engine components at simulated altitude conditions. The technology GE is advancing  will help make hybrid electric flight a reality for everyday commercial air travel, and it should have a real and necessary impact on the carbon emissions associated with flying,  Ali says.Specifically, GE and NASA ran a megawatt-class, multi-kilovolt hybrid electric system in conditions simu stanley cup lating altitudes up to 45,000 feet. One megawatt could supply the equivalent of more than 600 U.S. houses.Components were tested independently and as an integrated system. Additionally, multiple operational modes were evaluated, including power transfer from side to side, power assist to a sim stanley tumbler ulated engine, and aircraft power generation. The implementation of energy storage was also simulated. This proves that we are altitude ready,  Ali says.  Next is to prove that we are flight ready. The test took place at NEAT 鈥?N stanley italy ASAs Electric Aircraft Ouwm 鈥婼IA quietly parks its first A380
 Thanks to a $20,000 grant, Presque Isle will make its polls more accessible on Election Day.The city received the funds from the nonprofit Center for Tech and Civic Life, founded in 2012 to help more Americans engage in the democratic process.Officials will use the money to buy a new voter booth that is accessible to handicapped people, a wide-body wheelchair for voters, larger-print signs to direct the public and laptops for election officials, said Kim Smith, resource development and public relations officer. As a result, more people will have access to voting. This grant will allow the city to purchase signage with a large type face so as not tointimidate or alienate voters, support proper process and navigation of the polling site, and use accurate instructional illustrations to help low-literacy voters,  Smith said Tuesday.Presque Isle has not received public complaints about access, but officials have seen the need for better, larger signs and easier navigation  stanley usa during voting, she said.The Department of Homeland Security noted election infrastructure was a critical need in 2017, yet most local governments dont receive regular federal money to help conduct national elections, she said. Until  stanley cup the time Congress provides ongoing funding to help offset federal election costs, the grant will help.Mor stanley termosar e than 35 million Americans with disabilities are eligible to vote 鈥?about a sixth of the total voting population, according to the U.S. Election Assistance Commission.
