A remarkable thing about that modern London bus stop sign is that even when implementing the latest technology, they still use the typeface designed in 1916, unlike here where designers change typefaces like underwear.

"The most influential typeface of the early twentieth century, it was originally commissioned in 1916 by Frank Pick of London Underground Railways for use in signs on the railway system. Originally called "Underground", it became known as "Johnston's Railway Type", and later simply "Johnston".

These solar powered lights and bus stops can turn out to be quite cost effective. Often there's no close by electric lines to power a conventional sign, so the deferred cost of running those lines can subsidize the higher cost of the solar installation.

It's a rather expensive way to generate solar power, on a Kwhr basis, as there's so much duplication of wires, switches, enclosures and batteries, but each unit is a fairly low cost for a transit company. This allows for a few demonstration installations, or a slow rollout.

When installed near existing electric lines, the solar electricity could feed into the mains during the day, helping to shave peak demand, and avoiding the costs of batteries.

In answer to your last question: Yes.

The listing of renewable energy companies is impressive. If I were an investor and liked ocean energy (which I do), I would invest in the two companies listed under Wave and Tidal Power.

I think that ocean energy is bound to grow and that within a few years, we will be depending upon it with great reliance. It is energy in such concentrated form that harvesting it will certainly be a worthwhile economical venture.
