[Stoves] Ecat and decentralized power

I have built methane digestors, solar collectors, solar distillers in Peace Corps.

I have seen how they fail to meet the needs of people.

Wood fires continue to plague the world.

All are complex and not appropriate to all developing countries.

I have seen the problems of the air conditioned driven power grids in the US.

I managed a centralized electric power system in US Southwest. I built software for large wind farms. The failures due to power market manipulation (Enron) and under regulation (FERC Bush Admin) are really secondary. The real problem is centralized power. Large distances and right-of-way issues will kill large solar and wind problems due to transmission rights-of-way. Southern CA is where we see this today.

Ecat, if real, will resolve many of the issues of centralized power.

It is not cost effective today to use it soley for power production.

Ect runs at 1000 F.

Making it not efficient enough to replace natural gas turbines or coal plants.

But the waste heat from the systems can power personal thermoelectric generators and heat water and homes.

It will allow decentralized systems because it is relatively safe and can be widely used in small power grids.

Example: If each home owner has ten ecats (200 kW heat = 15 kW electric approx). By selling electric to the national grid a micro grid can be self balancing on most days.

The user gets to use waste heat the grid buys the excess electric.

This scales very well.

Even developing countries could adopt the plumbing skills to build and operate Ecat.

I was a mechanic for diesel engines as a teenager and worked on family farms and in canneries. I have alot of practical experience with mechanical systems. Ecat will be fairly easy to operate from what I have read.

It remains to be proven the exact amount of energy this technology will  produce. But applications can now be visualized for its use.

Subject: [Stoves] smoke that cigar will ya ?

Here we go again, the sure fix solution for the third world, eh ?

What part about  "local capacity development" do we NOT GET ?

Look at the process for making the cigar:
• How much less the energy input and technology is required.
• Who controls that ?
• What skills are gained by those who will use manage and maintain it…

Again friends, if all it took was a new technical fix like this and the dozns of well intended flops over the years, we could have flown over the third world and parachuted them in and that would have been  that.

But its not ...
Development is so much more complicated than that, the real sticky stuff of working within the context of the eventaul user adopter…

Question is who benefits MIT the various scientific luminaries and their institutions around the world , or the actual user…
Show us how it can be made in country how it can be adapted to locla management Accept less efficiency in the technology for more effectiveness in local adaptaion.

Egad, I'm getting abit to old for this..

Replacing charcoal production would save trees and prevent deforestation all over the world.

A new reactor Ecat could be simplified into a cooking ceramic stone that produces 1000 F (580 C) temperature.
This stone could produce heat for years, replacing wood fires in developing countries.
A red brick with a cigarette sized reactor inside could cook food and sterilize water.

SAM Kargbo works for SUNY in Albany, NY - Sam is a SUNY educator who grew up in Africa. "This (nuclear cooking stone) sounds really promising. I believe it will help millions. You are right, deforestation is one big problem in a continent like Africa. Many places in Africa are now dry due to the loss of trees being cut down. I would definitely be the first man to go sell the new invention (cooking stone) for you in Africa. "
Scratch Ecat Cartoon: There are more references below.

Ecat uses hydrogen as its primary fuel.
Managing hydrogen ions limits sustaining the Ni/H reaction.
A ceramic Ecat using a solid-state hydrogen fuel source would allow Ecat to be widely used.

US Air Force lab reproduced Ecat and reveals Nickel catalyst.

Ecat could be used in the home to produce steam for heating, hot water, and electric generation for homes and cars.



See attached (Ecat_Nuclear_Reactor_Rankine_Model.doc)

Nickel is a very common waste product from copper mining ($12.10 /LB).
Nickel is the 5th most common element on earth.

The Ecat uses 50 grams of Ni to produce 25kWh (approx)


Girls in developing countries must collect firewood and leave school.

Could students devise a small cigarette sized Ecat to place in a brick to produce heat for cooking?
See attached Nuclear Cooking Stone.doc

I worked at Los Alamos National Laboratory (90-91).
I was a Peace Corps Volunteer working on renewable energy and water in Jamiaca, WI in the 1970's.
I saw the deforestation by firewood collection in Haiti.

Could NIH and DOE develop a solid state hydrogen fuel to power the cooking stone?
