To live a comfy life and reduce energy needs the most expensive thing is hot water. Air to water or ground to water heat pumps are the most efficient way because you get heat from the environment. They're about 4x efficient. Excess solar can drive the heatpump's compressor and voila you have cheap hot water! While you can buy heatpumps for heating hot water it is definitely something that could be hacked from heat exchangers and old refrigeration gear.
Some machining crashes for your viewing pleasure
Amusingly they have more than one youtube channel. Here is an even cheesier video:
Seems they went bust not long after that video was released. They were too reliant on the oil and gas industry - new projects have suffered due to the low crude oil prices for the last few years,
Here's the plant list, the machine I used there is under "LARGE CNC VERTICAL TURNING". 2 meter diameter by 1.5 meter height by 12 Tonne refers to the size of the job that could go on the machine:
I liked that machine - it motivated one to not make a single mistake because the result would be death. I also liked that when turning nuclear submarine propshaft seals out of inconel I could put one cut on single block and wander off for nearly an hour. Both ears always listening to it cutting though, because inconel is a very unforgiving substance!
@nanomonkey it's proprietary CAM with a minimum of CAD thrown in to be useful. Vectric Aspire 8. As far as CAM goes it is cheap and not shit in comparison to other CAM systems. I'm really impressed with it compared to other systems I've used, but compared to how I think it should be..... I completely agree with @Dominic that it's unimpressive. I have been dropping hints that the world needs a decent system..... not especially subtle hints, but dropping them nonetheless.
Build a house, a pool, a sculpture, a boat. A robot like this could do many things...
150Kg payload 2.8m reach 0.2mm repeatability
If you want it to be small and 15hp won't lift it out of the water then a redesign is necessary anyway!
The coastguard would definitely tow us.... after disaster strikes while testing haha
That book looks great! I like his test rig on the cover. Just need someone with a speedboat / jetski to tow it for testing.
I like that idea. The hydrofoil is way more interesting than the shark - but a hydrofoil with wheels........ now, that's cool :) let's build one. Sinclair C5 size for a laugh.
Another type of additive CNC machine. CNC filament winding. This one is home made:
