A booming segment of the Perpetual Motion Machine industry is capitalizing on the hype over the "Hydrogen Economy" with claims to produce Hydrogen for impossibly low cost.

Engineuity Aluminum or Magnesium Wire System

Engineuity R&D a startup from Ashkelon, Israel announced a "Breakthrough in Alternative Fuel". From the write-up at Fuel Cell Works:

Using a light metal wire (such as: Aluminium, Magnesium), water and a special conversion unit, the company has succeeded to produce a continuous flow of hydrogen and steam under full pressure, temperature and power control.


How original! Who would have thought of using Aluminum wire to make Hydrogen? Besides Francois P. Cornish. And who would have thought of using Aluminum and Magnesium? Besides Hydrogenerate.

The volume required for containing the metal wire is similar to the volume required for petrol; however its weight will be 3 times greater. These values are significantly preferred over those associated with other alternative fuel solutions. The cost of this new fuel will be comparable with petroleum fuels at present day prices.


Gasoline must be darn expensive in Ashkelon. The reaction Mg(s) + 2H2O(g) Mg(OH)2(aq) + H2(g) yields one mole of H2 per mole of Mg. One gallon of gasoline is 130.88 mJ, and a mole of H2 is 285.83 kJ, so to replace a gallon of gas would require 457.89 moles of Mg. Multiplying by its atomic weight of 24.3050 we can see that's 11.129 kg of Mg. A gallon of gasoline is 2.791 kg, so the equivalent Mg weight 3.988 times as much, which in Ashkelon rounds to 3. And let's forget the weight of the ash tank. Mg costs in the neighborhood of $2 per kg. So gasoline must cost more than $20 per gallon in Ashkelon.

I should add that I intentionally ignored what Hydrogenerate called "the valuable by-product", Mg(OH)2. Recycling that isn't going to change the cost much.

Bunk.

Recycling would cut the cost by half. So only $10 per gallon-equivalent. (grin)

Plus the cost of the change in infrastructure, but think nothing of that.

Okay, I liked Cornish better than Alternate Energy, but this one is slain too.

I love that the person who wrote this thinks that after reading a second hand article they instantly are an expert on the Engineuity system. Did anyone begin to think that since hydrogen fuel can be used more efficiently than gasoline (in both engines and fuel cells), perhaps maybe the smart folks at Engineuity don't need to use as much. Not to mention the energy they plan on recovering from the steam created, might help some too.

Oh and in case anyone was expecting gigantic (and hence expensive) changes in infrastructure, the Engineuity system can use the same production lines and distribution systems that exist today. Any minor tweaks would without a doubt fit into normal infrastucture improvement budgets of any intelligent company.

Finally there is this remark: "And let's forget the weight of the ash tank." I am assuming this refers to the resultant oxides produced. Any suggestion that the system is somehow adding mass to itself by eliminiting hydrogen from the water is rediculous. If the statement refers to an added "tank" to store the oxide the author might want to double check the design before s/he claims that there even is such a thing. And even if there was, the size and weight of such a tank could not make a significant impact on the efficiency of the system.

From my point of view both the system is safe. Aluminum is far best option if we have to chose one from both.
