As I haven't been available to contribute much to gasification for the last few months, thought you may be interested to hear about Sweetwaters, New Zealand's equivalent to Woodstock which as most know was a huge rock music venue in the U.S.A.
I was asked
last September if I could put on a gasification demonstration and possibly
supply electric power to some of the stands for the four day event, January
22-25. As it wasn't going to cost anything for the site, and was really
to show the attending Greenies what could be done with renewable energy,
it was a chance to get some suntan.
Both my gasifier and their engine hadn't been used for over a year, so anything that could go wrong didn't. The gasifier fired up in 10 seconds and the engine started on gas in just under 4 minutes, and the power flowed! The output of the genset is only 5 K.V.A. 240V, so we didn't have a huge wood consumption to worry about.
The 10kWe Pioneer Class was built way back in 1987, to see if a simple design could be as reliable as the larger Pacific Class. It was never considered for commercial sales even though its proven itself time and again over 12 years.
Also in attendance were the do it yourself gasifier enthusiasts, some spending four days trying to get their engines started on gasoline. Only one drove itself on site and left the same way on gas, which for a small bus (top speed 120km/hr on flat) is a real performer.
It was an opportunity to provide assistance to those building gasifiers and sort out their operating procedures. Even the crudest design will make gas albeit terry, but not even that when the fuel was firewood stove billets!
Surprisingly, I was informed that two of the earliest gasifier hearths we sold (about 79-80) were still in use on pottery kilns. When built these hearths had an unknown life span, so our later models should still be making gas in 2020 and beyond, that is if anyone around still knows how to operate them.
Shell and BP were present with their P.V. cells and as Shell were using the P.V. cells to power an electric water cylinder (for a coffee stall) they ended up using a genset for part of the time as nobody likes cold coffee.
