[Vo]:Direct electron thermal transport.

[Charles M. Brown]

Vorts,

Could the electron affinity transporter based on H2 or CO2 
or H20 be simplified to use an array of LaB6 (a stable low 
work function material) orthogonal needles facing a flat 
anode with a nanometer scale gap in a vacuum? There would 
be preferential electron transport from the needle to the 
plate. A variant, which I hereby put in the public domain, 
is to have a 3 ? 7 angstrom insulating solid that 
electrons can tunnel through instead of a vacuum. This is 
also a variant of a diode array where Schottky anodes abut 
n type semiconductors. It is difficult for me to decide 
between the two.

I was unimpressed with Feynman's dismissal of diodes as 
thermal / electrical ratchets which he mentioned in 
passing as doomed to fail after doing most of his 
presentation with his paddle wheel / ratchet wheel / pawl 
device which he taught was doomed to fail. 

I believe that a variation with multiple unsprung pawls 
would rectify the Brownian motion driven ratchet wheel's 
rotation. Having at least one pawl in blocking position 
would stop the wrong way rotation while the pawls would 
move at random without pounding the incline. The 
probability of no blocking decreases exponentially to the 
number of pawls.

Aloha,
Charlie
