What is the cause of more corrosion with DC compared with AC? Tom T R Miles Technical Consultants [email protected] from mobile.

There are 5 fridges, 2 deep freezers, vacuum cleaners and whatever one needs for moderate comfort. We rent 4 of these houses to holiday makers from all over the world. There is no utilities. We run 90% solar with deep cycle battery at 240 DC (108 cells). All lights are on DC, directly from the battery. This avoids us emergency lighting in all these houses. We run our LAN over the DC grid and have WLAN at each end. All sockets are A C.We convert DC to AC in a standard 230 V 45 A Freq drive set at 50 Hz, than step it up to 230 VAC. Works fine and is reasonably cheap. My experience over the last 25 years is that DC gives us much more trouble than AC! It is not only the switches, but also a lot more corrosion at any connection. If there is a bit of humidity inside the installation tubes, DC lines tend to foul and produce smoldering fires. The Grundfos submersible pump works great on D C!

So much process design is obsolete because engineers aren't willing to learn new ways. Disruptive, advancing technologies are being suppressed. Sincerely, Leland T.

(Open cook-fires are a major cause of chronic respiratory abuse!) What lacked is a, “Build it! They will come,” attitude. But as in the wonderful metaphor, suggests: “Cream rises to the Top”. We must be energized ; nervous...and be ready for when all those Cyborg eggs start start hatching, and dues of today, become due, for the rest of our profligate society; as well as a wide swath of Church Ladies that just knew, (My Dear!!) but Sent by my uPhone On Nov 10, 2018, at 5:40 PM, Anderson, Paul <[email protected]> wrote: Jess, Is the price of grid power so high there that it is economical to generate power with a biomass system to sell power to the grid? Electrical power topics are a bit outside of my base of knowledge. So, I cannot comment about splitting of 3-phase power. Maybe just create the power in single (split) phase. But I do know something about charcoal gasification that can run internal combustion (IC) engines. And about the making of appropriate charcoal. You could use the heat from burning the pyrolysis gases for your drying purposes. Much depends on the amount of biomass you have available. Some places are with such excess biomass that people pay to get rid of it, or give it freely. A little more about your situation could clear that topic. Much depends on how much you really need to create your own power with biomass. Paul Doc / Dr TLUD / Paul S. Anderson, PhD Exec.

We are offgrid, with 3.5 kw of solar and a 5kw generator as backup. We can get a connection to the grid of 30kwe but only single phase. I would like to source a chp unit to provide power to us and also to the grid, plus use any heat for drying woodchip. I presume you can split the 3 phase supply and export OK? I am allright with nuts and bolts, currently running 2 biomass boilers and drying systems. Thanks for your interest. I have looked at the Spanner system but the price does not work with regards to the economic payback. Yours, Jess Christman Swallowfield Smallholding Ltd.

We are off grid and produce woodchip, so it would be a good fit. I am just concerned about reliability.
