Elmer, interesting purchase by intel. From your link, here's an athlete's perspective of this smart eyewear.

Korea Leaves West Behind In Fuel Cell Race
http://oilprice.com/Alternative-Energy/Fuel-Cells/Korea-Leaves-West-Behind-In-Fuel-Cell-Race.html
...
Older deals include LG Corp. taking a 51 percent stake in Rolls Royce Holdings Plc’s Fuel Cell Systems, and GE agreeing to manufacture fuel cells in the U.S. and Asia with South Korean company GS Caltex Corp.
While the fuel cell focus is on industrials, the North Asian nation hasn’t forgotten about the automotive market.

Chef911, the health considerations also caught my attention. For example, inhaling aluminum powder has been associated with Alzheimer's.

TheCleos, you have a strong argument in that Arcam is the only EBM provider. Though, AVIO (in Italy and bought out by GE) is building turbines using arcam printers made out of titanium aluminide. Avio recently opened a new 20K sqft facility which uses arcam printers. "The speed of production is also incredible, allowing GE to fabricate eight turbine blades in just 72 hours from one machine."

Looks like GE is not concerned about arcam's survival.
Your other point about arcam's stock decline is very well taken. I too have my doubts and would never try to convince others that the market is wrong. With that said, I bought at $16 and my next buy point is $14. It's certainly a gamble -- but a good gamble imho and worth placing a small bet on it.

When I start doubting my investment it's time to reevaluate. I revisited the advantages DMLS versus EBM.
DMLS pros:
1) higher resolution
2) thus, superior for intricate internal structuring
(e.g., leap engine fuel nozzle)
3) easier to remove remaining powder
EBM pros:
1) significantly faster
2) far fewer supports and anchors required
3) less post processing
4) less material needed/less strap
5) more applicable for the orthopedic implant parts
cons:
1) High chamber temperature
(resulting in lower resolution due to unwanted sintering)
2) printer is more temperamental to surrounding environment
(i.e., prone to external magnetic field disturbances)
Please feel free to correct or add. Btw, it takes for ever for shares to fill! I bought at 44, 38, 29, 24 and now at 16.

Review of 4 Hydrogen Fueling Stations in Los Angeles Area

Ecomike, plug power forklifts and LA hydrogen fuel cell buses certainly run longer than 10 seconds! LOL
How long can a bus run using a formic acid fuel cell? I am unable to find any real world example. I would appreciate some links.
And does the freezing point of formic acid (8.4C) cause problems in low temperature conditions?
Okay, stoichiometrically one mole of formic acid weighs 23 more times one mole of H2. So it requires 44 g/mole of mass (CO2) along to hold 2 grams of H2. Expensive piggyback ride.
cooler
Reread the post. Here, this may help. When given equivalent masses of H2 and formic acid, H2 gives off more than 23 times the energy.
cooler
You are contradicting yourself.
Excomike, formic acid gives off less energy per gram (heat of enthalpy) of material and weighs 23 time more than H2! 1 kg of H2 gives of more energy than 23 kg of HCO2H. Formic acid does not provide the power needed for a forklift or car. Per gram hydrogen trumps NaBH4 and HCO2H -- they don't even come close. Formic acid (like coal and all other carbon sources) gives off CO2 -- no too environmentally friendly is it.
cooler
Ecomike, so NaBH4 is a better alternative to formic acid. Another nail in the coffin for MVTG. Btw, NaBH4 is a H2 precursor.
cooler
Problem with formic acid is that it's very corrosive. It has a pka of 3.75 which is significantly stronger than acetic acid (pka 4.74). It has a very pungent smell and chronic exposure to humans causes kidney damage and to the optic nerves. Low molecular weight carboxylic acids (the class of cmpds it falls in) are typically strong in odor. E.g., acetic acid, butyric acid (aka liquid vomit) and 5-C variants are your typical agents of locker room smell. Hydrogen, H2, is very stable at RT and does not smell. It is nonpolar and easy to store. Hydrogen is the most abundant element in the universe. It is green friendly, and the formation via, 2 H2O --> 2 H2 + O2 can be powered using solar energy. Hydrogen sources trump formic acid sources by a mile (and then some). If you look at electrochemical energy released per carbon content from methane to methanol to formic acid, formic acid gives off the least amount. Oxidation of hydrogen surpasses all of these AND no CO2 is given off! You keep mentioning that hydrogen gas is very explosive -- and you are correct -- but you can have it both ways. Because it is so exergonic it's a better source of energy. Formic acid fuel cells are less efficient then hydrogen fuel cells.
It's formic acid which is toxic to the body.
Are they using an ammonio methacrylate copolymer?

Windbag, good point about Rob being a positive bellwether for sigma.

Excerpt from the above link:
Hydrogen fueling station in Emeryville and Alameda, California.
AC Transit Emeryville Station in California takes only six minutes to fill a transit bus with 30kg of hydrogen which can run for up to 16 hours of stop'n'start driving.
I was off by one dimension. It's 10,000,000 cubic feet and not square feet. Okay, this pares down the size to about 9 football fields assuming a 20 foot high facility.
Andy Marsh calls this a modest deployment in size when compared to other GenKey customer sites!

heavenlystars, your broker was correct. This is equivalent to more than 170 NFL football fields.

Jackle, nice article. These selling points never get old --
Haven't posted for awhile but have been diligently following this board. I purchased my first shares back in late January of this year and since then have been slowly accumulating shares. Initially I would place low-ball bids at 0.05, 0.08 and 0.10, in hope of catching some shares. Never happened. So the shares I own are in the range of 0.11 and 0.14.

The Pac-Car II is the world's most fuel efficient car using a hydrogen fuel-cell which obtained a fuel economy of 12,665 miles per gallon gasoline equivalent back in 2005. This world record is certified by the Guinness Book of World Records. In one event this car went nearly 13 miles on 1 g of hydrogen driving at an average speed of 19 mph. A current US penny weighs about 2.5 grams.

Electric cars can go only half as far in freezing weather, AAA finds
http://www.latimes.com/business/autos/la-fi-hy-aaa-electric-vehicle-range-20140320,0,3522803.story#ixzz2wWphMXOq
Testing by AAA has found that how far an electric vehicle can travel on one charge varies widely depending on the weather. Frigid temperatures can reduce that distance by 57%.
The research is important to the Automobile Club of Southern California because it maintains mobile recharging trucks for people who misjudge how far they can go in their electric car.
“EV drivers need to carefully monitor range in hot and cold weather” said Steve Mazor, the engineer who manages the Southern California club’s Automotive Research Center.
