NASA Technical Reports Server (NTRS) - N-type Doped PbTe and PbSe Alloys for Thermoelectric Applications

NASA Technical Reports Server (NTRS) - N-type Doped PbTe and PbSe Alloys for Thermoelectric Applications | Thermal to electric conversion | Scoop.it
The present invention demonstrates that weak scattering of carriers leads to a high mobility and therefore helps achieve low electric resistivity with high Seebeck coefficient for a thermoelectric material.

The record-breaking Stanley engine...

The record-breaking Stanley engine

The figures show the two-cylinder reciprocating steam engine fitted to the Stanley Steamer automobile which set a land speed record of 126 mph in 1906 (!). This engine is now in the Smithsonian Institution. 

This is a diagram of the very effective twin-cylinder reciprocating steam engine which was fitted to the Stanley Steamer motor car:

 

 

 

Images of a record-breaking engine of this type, now in the Smithsonian, can be seen here; warning: these images are 280K in total. This engine weighed about 85 kg and was reputed to develop 250 hp. Modern practice could improve substantially on these figures. A typical rotational speed for such an engine operating non-expansively at high pressure is 1100 rpm. Its high torque is maximum at startup. This type of engine can run for long periods between services and is very straightforward to maintain, and its inherent reliability is much greater than that of an internal combustion engine, especially a spark ignition engine.

 

 

Alain Coetmeur's insight:

Using today the E-cat tested in Lugano and this turbines, you can compute that an Boeing 747 and it's 150tons of kerozen may fly with 40tons of E-cat, 80kg of nickel and LAH, and 50tons of steam engine (1.4kW/kg) ... letting 30 tons for plumbing...

This is not realistic, but this mean that using LENR to power a jumbojet is a question for engineer, not for priest.

Microgen Concepts's insight:

A simpler, smaller, cleaner machine
The term "supercritical" describes the state of carbon dioxide above its critical temperature and pressure, 31 degrees Celsius and 73 atmospheres. Under these conditions, carbon dioxide has a density similar to its liquid state and fills containers the way it would as a gas.

 

Supercritical turbines would also be an attractive upgrade from steam systems aboard ships and submarines, producing the same power while occupying less space. Because they use carbon dioxide instead of water as their process fluid, these turbines would also work well in drought-stricken areas.

In addition, a supercritical turbine could fit into a directly heated cycle, where a fuel like natural gas burns in the presence of pure oxygen inside the turbine, creating only water and carbon dioxide as waste.

Cracking the code for surface coating of gas turbines - Engineering Materials

Cracking the code for surface coating of gas turbines - Engineering Materials | Thermal to electric conversion | Scoop.it
A study at the University West (Högskolan Väst) investigated the shape and number of cracks in gas turbine coating and found that not all cracks are bad.

The surface coating used on gas turbines to increase lifespan, consists of two layers – one of metal to protect against oxidation and corrosion , and a ceramic one for thermal insulation. The structure of the coating varies, with pores and cracks of different sizes, which determine the efficiency of the thermal insulation and the length of the coating life-span. - See more at: http://www.materialsforengineering.co.uk/engineering-materials-news/cracking-the-code-for-surface-coating-of-gas-turbines/73786/?__scoop_post=97af0600-b454-11e4-93c7-842b2b775358&__scoop_topic=1472349#__scoop_post=97af0600-b454-11e4-93c7-842b2b775358&__scoop_topic=1472349
