The Primary reason the airborne MW lasers had issues, were that they were chemically induced/powered. On these, the ship supplies the power. Honestly, though, the necessary power could be supplemented via an MHD generators, either airborne, shipborne, or land mobile.

The U.S. Navy, which has already developed a 30-kilowatt laser that has been used operationally, will soon test a new directed energy weapon that is five times more powerful, said the vice chief of naval operations July 23.
The Office of Naval Research “will perform a shipboard test of a 150-killowatt laser weapon system in the near future,” said Adm. Bill Moran during a speech at Booz Allen Hamilton’s Directed Energy Summit, which was held in Washington, D.C.
The Navy’s 30-kilowatt laser weapon is currently onboard the USS Ponce. The system, which has been used operationally in the Persian Gulf, offers military leaders precision accuracy at a low cost, Moran said.
The laser weapon system, or LaWs, "has an extremely low-cost per engagement ratio,” he said. “We’re spending pennies on the dollars … every time we use that capability.”
While the U.S. military is developing laser weapons that can be installed on platforms across the Army, Air Force, Navy and Marine Corps, military leaders must be cognizant that potential adversaries are as well, Moran said.
“These technologies are being developed and fielded by a growing number of countries all around the world, it’s not just us,” he said. “If we don’t get ahead of that capability by our adversaries, we’re going to find ourselves in a very difficult position in the future.”
As the Navy considers its future fleet design, laser weapons must be a part of the equation, Moran said.
“If we have to continue to rely on projectiles, propellant-driven projectiles, we will run out of our ability to defend ourselves over time,” he said. “This capability in directed energy is incredibly important."
Military engineers are turning science fiction into reality, but such technology needs to be pushed out to the services faster, he said. The Navy cannot afford to wait 20 years to advance directed energy weapons.
“Our future success as a service depends largely on the efficient and rapid development and acquisition and fielding of this game changing technology,” he said.
Advancements in laser technology fit in with the Pentagon’s current third offset strategy, said Gen. Ellen M. Pawlikowski, commander of Air Force Materiel Command.
“I think we are pretty well postured to be part of this third offset, to be able to be what I consider the pointy end of the third offset,” she said.
The strategy is a plan to maintain the United States’ military superiority through investments in emerging technology such as autonomy. For example, unmanned aerial vehicles could carry laser weapons, giving operators precision strike capabilities and reducing collateral damage, she said.
Pawlikowski urged developers to not repeat the mistakes that plagued previous efforts, such as the airborne laser program, which Pawlikowski once oversaw. The mega-watt laser program, which was canceled at the start of the decade, faced major cost overruns and schedule slippages.
“I want to make sure that we don’t have another five or eight year development program that we told everybody we were going to do in three to four,” she said. "It’s so vitally important that we continue this path of expectation management and we target for something that is achievable within the bounds of the state of technology as we see it today."
Well, Britain voted for survival. Or at least England and Wales did. Scotland and Ireland did not....
Things are still interesting.
If anybody were to call their local Post Office and ask about changes to regulations on shipping rifles and shotguns, they might be pleasantly surprised. If the personnel aren't aware of what's changed, ask them to check the latest update to the Postal Bulletin. Might make a big difference to those of you who're gonna cross state lines to go hunting, or for any other reason. Imagine shipping your rifle ahead of time, instead of goin' through the hassles of checking in when flying.

Quote from: Flight-ER-Doc on June 17, 2016, 09:06:38 AMToo bad we can't use DDT properly to kill mosquitoes.
*Sigh* Turns out the evidence, wasn't. "Silent Spring" used trumped up falsehood. The ban has been responsible for for an estimated 65 million unnecessary deaths.
This is what you get, when you use Pop-Junk Science, and Politicians keep making technical and scientific decisions. And "Scientists" keeping backing them.
It's like Carl Sagan and his "Nuclear Winter". If you actually read his papers, it's "Nuclear Autumn" at it's worse. And Sagan's Really, Really Bad, with his math. I guess if you're famous, nobody checks your conclusions.......

http://www.gizmag.com/weak-electrical-signals-diabetic-wounds/43913/When the body sustains a wound, electrical signals around the site of the injury help cells migrate there as part of the healing process. While this works well in healthy individuals, new research out of the University of California Davis (UC Davis) reveals that when such wounds happen to diabetics, the electrical fields around them are significantly weaker, leading to the slow-healing process common to people with the condition. By manipulating the electricity around wounds, the researchers feel that they might be able to speed the healing process and help diabetics thrive.In reaching their conclusion, the UC Davis researchers worked with the eyes of diabetic mice. The mice had been given the disease either through genetic engineering, the use of drugs, or from a high-fat diet in an effort to control for the different types of the disease. In all cases, small pieces of the mice's corneas were removed via a scratch.Using the highly sensitive equipment at the UC Davis bioelectricity lab, the electrical currents at the edges of the scratches were measured and found to be significantly weaker in the diabetic mice than in healthy mice with identical wounds. This was further correlated to a slower healing time. Such a finding could help scientists develop an electrical stimulating healing process that could help diabetics heal from sores and other wounds faster."We think we will be able to speed up healing by increasing the electric currents around wounds," UC Davis' Min Zhao tells Gizmag. Zhao is a professor of ophthalmology and dermatology, who led the team responsible for the research. The group's work appeared in the journal Scientific Reports on June 10. "We are developing two approaches," he adds. "One, by addition of pharmacological agents to enhance transport of ions that would crank up the endogenous electric signals; and two, by the external application of electric currents using electrical contact lens with multiple electrodes."Zhao originally made the link between wound healing and electrical currents in a previous study.
Too bad we can't use DDT properly to kill mosquitoes.

http://www.theverge.com/2016/6/16/11956278/us-zika-birth-defects-cdc-three-infantsThree babies have been born in the United States with Zika virus-related birth defects, according to figures released today by the Centers for Disease Control and Prevention. The report noted an additional three "pregnancy losses with birth defects" in Zika-infected mothers.[/size][/font][/size]Since Zika was declared a public health emergency by the World Health Organization five months ago, doctors have been working to understand and track the disease. This is the first time the CDC has reported any pregnancy losses or babies born in the United States with Zika-related defects, according to Stat.[/size][/size]The data in the CDC's report is from last week, and the agency updates it weekly with anonymized information about any pregnancies where the mother has "laboratory evidence of possible Zika virus infection." Data comes from the US Zika Pregnancy Registry, a system created by the CDC to track reported infections in pregnant women, and the outcomes of their pregnancies.[/size][/size]BIRTH DEFECTS CAN INCLUDE MICROCEPHALY AND NERVE DAMAGE
[/color][/i][/color][/size]In mid-April the CDC confirmed that women with Zika virus, especially those who become infected early in pregnancy, may give birth to babies with abnormally small heads — a condition called microcephaly. Zika is transmitted via mosquitos or sexual intercourse, and since early this year it was suspected to cause a range of birth defects.[/size][/size]The CDC's announcement today did not specify which birth defects the three babies were born with. It simply stated that they included "microcephaly, calcium deposits in the brain indicating possible brain damage, excess fluid in the brain cavities and surrounding the brain, absent or poorly formed brain structures, abnormal eye development, or other problems resulting from damage to brain that affects nerves, muscles and bones, such as clubfoot or inflexible joints."
[/color][/size]The report also did not make clear whether the three pregnancy losses in women infected with Zika were voluntary terminations or miscarriages.
[/color][/size]So far, 234 pregnant women in the United States and 189 in US territories have been diagnosed with Zika virus, Stat noted.
Not to worry, Ken. I sure glad that there's somebody with the interest, expertise and time to keep contributing. I try to get on here 3-4 times a week and I'm always happy to see new info.
