Can't possibly work. We've been told on here you need at least 2
horsepower to lift dust.

48 volt would deliver quite a bit of power over telephone drop wire.

Panels are now down below 50p/watt I think.

Still a lot more expensive that biting the bullet and installing a
proper mains supply. What's the problem with a overhead on a catenary?

Nothing whatsoever. However if you had provided a bit more context then the
relevance of my comment would have been obvious.

Modified sine is no good for any tool that that has variable speed. Just
won't work.

Well mine work fine with my cheapo 500 watt modified sine wave inverter.

In particular a cheap multi-tool which is variable speed is quite OK
on the above inverter.

Most power tool use is intermittent so it is a doer. The issue is it
cheaper than running a cable with the terminations/fittings and of

Power it from a 13A plug in the house and you don't need a certificate.

You don't if you hard wire it either. Part P no longer applies to
outside installations unless you install a whole new circuit.

I think that is wise. I should probably have mentioned that I had a
couple of relatively cheap (£20 to £40) inverters fail in the 2-3 years
when I was running a handful of CFLs off leisure batteries, and a
battery charge lasts at least twice as long running 12 volt bulbs as
mains with inverter.

.... and running LED strips is better yet. My 12 Volt cheap&cheerful inverter CFL
lights took a long time to brighten up in freezing weather.

Replaced them with LED self-adhesive strips (clear rubber coated ones) drawing a
similar current, and these give more light, and it is much, much better
distributed. Instantly on, as well.

Plenty of 12 LED "bulbs" around, too.

In view of what's been said I think I might look at just aiming to have some lighting and use battery power tools and the extension lead for the occasional mains power tool.

One of these, or similar:
