Far-Out Tech Department Fuel Your Future Car With Aluminum

Link http://www.greencarreports.com/news/1076758_far-out-tech-department-fuel-your-future-car-with-aluminum


Thatís the idea being proposed by an Israeli company called Alchemy Research, according to GreenCarReports.com.

The startup says it has developed a reactor that that combines aluminum and water to create hydrogen, which is then used to generate electricity in a fuel cell or burned to create steam and run a turbine.

To do this, powdered aluminum is introduced into a pre-heated reactor where it is melted at a temperature of 900 degrees Celsius and reacts with steam to form aluminum oxide, a process that creates hydrogen and heat. The heat generated by the reaction then takes over powering the reactor, making it a self-sustaining system. The non-toxic aluminum oxide byproduct can be processed back into aluminum at a recycling facility to create new fuel.

1. At a cost of EXACTLY how much energy?

 

One does not "recycle" alumina back into aluminium. It's REFINED using exactly the same energetically expensive process as the one used to turn ore dug from the ground into metal.

4. 50MJ

It requires 50MJ of electric energy to convert oxide to 1 Kg of aluminum, containing 31MJ of energy. 60% efficiency, not that bad. Electricity is not the only component of conversion cost, there are also costs of smelter construction and running. Market price of aluminum is $1.9/kg, including all costs and manufacturer's margin. Assuming this cost, it is less expensive to run electric car on aluminum than ICE / gasoline car.

5. How do you come to that conclusion?

"Assuming this cost, it is less expensive to run electric car on aluminum than ICE / gasoline car."

I'd like to see the math on that, since the article doesn't exactly say how many miles per kg such a car would get. It only discusses miles per liter of aluminum powder.

6. $1 per 10km

According to the process model and results we obtained from prototype, eventually one kilo of aluminum ends up as 8.6MJ (2.4KW-h) of useful electric power. Tesla car consumes 13.5 KW-h per 100 km. So it will need 5.6 Kg of aluminum, at total cost less than $11.

7. Are you actually involved in the development of this technology?

You've worked on the prototype of this vehicle? Wow.
