Yeah, FreeCAD is great, but I can only think of one project that I’ve done where SolveSpace absolutely could not work for the geometry I needed and I had to rebuild it in FreeCAD. But that’s just a product of what I am building: simple things like brackets, knobs, and replacement lids mostly. I don’t need chamfers, drafts, lofts, etc. and I get what I need with minimum of time and effort using SolveSpace.

When I do need those features, complex geometries, or modification of pre-built step files, FreeCAD has never failed me.

No one mentioned SolveSpace, so… SolveSpace. Solvespace is a fully functional 3D parametric CAD solver in a free, cross-platform, open-source, portable, single self-contained executable 10 MB file.

I do a fair amount of hobby 3d printing and SolveSpace makes design and CAD stupid easy. The interface is perfectly laid out, the hotkeys are intuitive, and the capabilities make small-scale projects a breeze.

Now, the program has its limitations, but if I just want something quick and simple, there is nothing better.

It shouls be intrinsically safe. The water has a massive heat capacity and is an excellent shield for radioactivity. Also, recovery, if that’s what we want, is much easier, as we are recovering a solid material, rather than containing spreading sheen of tens of thousands of barrels of oil.

Nuclear reactors on land have real, demonstrated liabilities, but, in my opinion, the story would be very different over water.

Briefly, water is how we store hot radioactive waste right now. In fact, Randal Munroe of XKCD fame has a great video on spent fuel storage in pools on YouTube here.

Personally, I find difference in safety is so great in favor of the nuclear reactor that I cannot even draw a meaningful comparison. Would I rather drink water from from a spent fuel storage pool or one contaminated with fuel oil? Spent fuel every time. Would I rather live with an off-shore sunk nuclear reactor or an off-shore oil spill? Sunk nuclear reactor, 100%. Which would I rather be in charge of clean-up? Yup: Sunk reactor.

Is there a compelling alternative perspective here?

I’d also like to point out that the underlying model may well be unsustainable in the way that it is offered at the start. Who benefits when a for-profit company operates at a loss? We, the customers, do. We get low prices and customer-friendly practices that are genuinely enjoyable. That business can’t operate in that way indefinitely, as the early investors are not funding it as an act of charity.

Eventually, the bill comes due. The shareholders have funded the company on the premise that, after losing lots of money on customer acquisition, it can restructure and monetize those customers and recoup their investment, hopefully with a lucrative return when they decide to capitalize their holdings and find a new company with which to repeat the process.

There is absolutely no reason not to enjoy the perks of the early stage of the customer acquisition process; the shareholders are subsidizing your product at no cost to you. But we shouldn’t be surprised when the shareholders stop subsidizing and start squeezing their formerly pampered customers in the hopes of getting their money back (and more, of course).

This doesn’t excuse unethical or abusive practices, but it does mean that, even without them, the experience of those early days probably wasn’t going to last forever.
