Have plans for suit based on LCG principle! Any mfg interest. Email on blog.
Let me know of any interest , Houston Fire has one in use! At right price, a great seller --- big market, just observe the news---- very few in use.
Firemen need a cooling suit!
Heat & Muscle performance---no reason for death or medical emergencies in HS Football practice
But what does overheating have to do with fatigue in the first place? Much of the lab's recent research can be summed up with Grahn's statement that "temperature is a primary limiting factor for performance." But the researchers were at a loss to understand why until recently. In 2009, it was discovered that muscle pyruvate kinase, or MPK, an enzyme that muscles need in order to generate chemical energy, was highly temperature- sensitive. At normal body temperature, the enzyme is active – but as temperatures rise, some of the enzyme begins to deform into the inactive state. By the time muscle temperatures near 104 degrees Fahrenheit, MPK activity completely shuts down. There's a very good biological reason for this shutdown. As a muscle cell increases its activity, it heats up. But if this process continues for too long, the cell will self-destruct. By shutting itself down below a critical temperature threshold, MPK serves as an elegant self-regulation system for the muscle. "Your muscle cells are saying, "You can't work that hard anymore, because if you do you're going to cook and die,'" Grahn said. When you cool the muscle cell, you return the enzyme to the active state, essentially resetting the muscle's state of fatigue. The version of the device that will be made available commercially is still being tweaked, but the researchers see applications for heat extraction in areas more important than a simple performance boost. Hyperthermia and heat stress don't just lead to fatigue – they can become medical emergencies. "And every year we hear stories about high school athletes beginning football practice in August in hot places in the country, and there are deaths due to hyperthermia," said Heller. "There's no reason why that should occur."

Space suits
Why Can't We Design the Perfect Spacesuit?Nancy Atkinson - Universe TodaySo far, every spacesuit humans have utilized has been designed with a specific mission and purpose in mind. As of yet, there's been no universal or "perfect" spacesuit that would fit every need. For example, the US ACES "pumpkin" suits and the Russian Sokol are only for launch and reentry and can't be used for spacewalks. And the Apollo A7L suits were designed with hard soled boots for astronauts to walk on the Moon, while the current NASA EMU and the Russian Orlan are designed for use in space, but with soft soled booties so as not to damage the exterior of the space station.What would constitute the perfect spacesuit that could be used for any mission? It would have to be lightweight while being impervious to rips, impacts and radiation, but also be flexible, fit multiple sizes, and be comfortable enough to be worn for long periods of time.With those specifications in mind, is it possible to create the perfect spacesuit?"Designing a spacesuit turns into a battle between protection and mobility," said NASA astronaut trainer Robert Frost in an article on Quora."The more we try to protect the wearer, the less mobile they become. The more mobile we make them, the less protected they are."The perfect spacesuit would be, to quote Elon Musk, "badass."That's the terminology the SpaceX used in their contract with suit-maker Orbital Outfitters, who are creating the pressure suit for SpaceX's future commercial passengers. Musk said SpaceX is looking for not just utility but esthetics, too. "It needs to both look like a 21st-century space suit and work well," he said during a reddit AMA.But even with SpaceX's 'badass' suit, they are designing with one purpose in mind.And there are obstacles to having a "badass space suit design," wrote Eric Sofge in an article in Popular Science. "A launch-entry suit is ungainly, an oversize one-piece embedded with rigid interfaces for the helmet and gloves, and enough room to inflate, basketball-like, when pressurized—especially in the seat, so an astronaut isn't forced to stand up."New IdeasOne of the best hopes on the horizon is a "shrink-wrap" type of spacesuit that MIT has been developing. It is a lightweight, form-fitting, flexible spacesuit — a la Seven of Nine on Star Trek: Voyager— lined with tiny, muscle like coils."With conventional spacesuits, you're essentially in a balloon of gas that's providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space," said one of the developers, Dava Newman. "We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."MIT is using a nickel-titanium shape-memory alloy and they are continuing to test ideas. Some problems with this suit include the difficulty of putting on such a tight suit in a zero-gravity environment and how a gas-pressurized helmet can be connected to the compression-pressurized suit.NASA recently revealed the winner of a public-voted spacesuit design called the Z-2. While it looks a bit like Buzz Lightyear's fictional suit, it has bearings in the joints that make more flexible than NASA's current EMU. It also has a rear-entry port, allowing it to be docked to the side of a mobile transporter or habitat, essentially turning the suit into its own air lock. This helps to avoid bringing in abrasive soil and dust such as lunar regolith Martian soil. NASA is currently testing the Z-2 prototype with plans to develop a better suit, the Z-3. If it works well, the Z-3 might be used in a spacewalk from the International Space Station by 2017.So, still, the perfect spacesuit eludes us.But here are some other additions that would make the perfect spacesuit:Self-healing: Currently, having multiple layers is the best way to defend against rips or tears, which can be fatal in the vacuum of space. But MIT's body suit would utilize mechanical counterpressure to counteract a rip, and engineers at ILC Dover are looking into integrating self-healing materials, such as polymers embedded with microencapsulated chemicals that would create a foam to heal a torn suit.Better gloves: gloves have been one of the hardest things to design in spacesuits. Making a glove that is both flexible and protective is a challenge. Astronaut Duane Carey compared spacewalks to trying to fix your car while wearing winter mittens. Astronauts have had skin rubbed until it bleeds and have lost fingernails because of how the current gloves wear. NASA is constantly working on better gloves.Augmented Vision: Currently, NASA's polycarbonate helmets could be confused with fishbowls. One material that could be used for future helmets is a clear ceramic called ALON, which is thinner than bulletproof glass and three times as strong. Another addition could be an internal heads-up display — like ones used by F-16 pilots – to provide data and information.A better cooling system: Current suits have "underwear" with about 300 feet of plastic tubing that circulate waters to draw away body heat. Purdue University engineers are developing a polymer using glass fibers coated with thermoelectric nanocrystals that absorb heat and discharge electricity.Artificial Gravity: Remember the magnetic boots worn in Star Trek: The Undiscovered Country and Star Trek: Insurrection? The University of Massachusetts is developing a dry adhesive that could help astronauts and those pesky floating tools to "stick" to surfaces. It is made of a carbon fiber weave and mimics the skin and tendon structure of gecko feet. Another idea — while not quite the same – is a way to counter muscle and bone atrophy in zero-G: Draper Labs are developing gyroscopes that could be attached to the arms and legs of spacesuits that could provide resistance similar to the force of gravity on Earth.Long-life Battery Power: One issue for long spacewalks is having enough battery power. Michigan Tech is developing units that can convert movement into electricity. Also, Elon Musk might have some ideas for long-lasting batteries…So, while many entities are working on ideas and concepts, the perfect spacesuit has yet to be developed. If humans are going to go to an asteroid, back to the Moon, to Mars or on a mission to deep space, we'll need a suit as close to perfect as possible.

We have it in x37b--all we need is C version, BUT as you heard in sotu -- dummy potus!
A scaled-up version with an astronaut crew to work outside the vehicle could reestablish America's ability to build and maintain big structures in Earth orbit.
America is not building a second-generation space shuttle but is instead building
three space capsules: the Orion and two others, from Boeing and SpaceX. All will land by parachute, like spacecraft of the 1960s, and none will allow space walks comparable to the space shuttle. Unlike Hubble, the next big telescope, the James Webb Space Telescope (due for launch October 2018) will have to be right the first time. There will be no way to repair it. It is already more costly than originally planned, and there is no shuttle to take astronauts to save it if something goes wrong.
The U.S. Air Force's Boeing X-37B, which began as a NASA craft but was transferred to the Pentagon in 2004, is an unmanned space plane that looks like a small space shuttle. Like the shuttle, it returns to Earth and lands on a runway. It has been flying successfully for five years. A scaled-up version with an astronaut crew to work outside the vehicle could reestablish America's ability to build and maintain big structures in Earth orbit.
