Subject: Re: [Stoves] Woodstove Design Challenge

I was particularly interested in the 30kV electrostatic precipitation,
yet it only reduced particulates by 62%, I was expecting more, before
I read up on it do you remember its power consumption?

>> I think it was around 30 watts, but not sure.

Also the nano particle counter next in your report, it mentions a 1nm
cut off, can you say whether it is cutting off less than 1nm and
sampling larger? (snip)

>> cutoff was 1 micron, ie 1000 nm.   .............N
