The newer, more efficient, solar water heaters do use a chemical liquid that can heat to about 120*C in the heat exchangers. It may be this that is harmful. It is much more than just metal and glass these days.

The solar-electric (photovoltaic) cells that generate electricity are a different case. I don't know much about the newer versions of this tech.

Every technology has its price, sadly.

If it was real, then yes patents would be bought for exploitation, not protectionism. This is the usual pattern with capitalism.
Whatever you believe about the environmental impacts of Shale Gas, it provides energy at about 20% of the cost of traditional sources and is spurring on the US economy at a rate that was not foreseen.

Cheap energy will fuel other economic growth. Even energy companies have share portfolios. In fact managing these is becoming a major task of FDs across the world. Once you are global it is not just about your company assets, your market and your industry sector any more.

Off topic, but related to theme songs. When we watched terrestrial TV we listened to the whole theme, even if only in the background while we quickly made a cup of tea or finished off some other chore. With streaming, or watching box sets, we quickly FF over the theme song and titles. We are missing a lot of great music.
Everything else said by the last two posters can be captured within the idea that we no longer live in a society, we live in a market.

A reasonable choice of lumber that has improved over time. Fancy hardwoods like walnut, and mahogany are in abundance. There are some plywood and rubber-wood boards available. There are also some kiln dried imported softwoods and merbao available. Some of the lumber is very green, so look for the kiln dried if you need stable timbers.

Echo everything said by others.
Breakfast great and the serve from 8am. Most other places say 9am and they still are not ready.
Sandwiches are cheap 22-32, and really packed full of filling. We got some sandwiches for a day out, the only mistake I made was ordering two, as this was too much. These are seriously good sangars, and they are wrapped in alu foil.

In fairness to Metro, they are a wholesalers, and not really a supermarket. Hence the need for a card, which can be got around.

They have improved in the year I have been away. They now carry a more consistent range of imported foodstuffs and they also seem to have sorted out the mported milk supply.

They have a wider range of electrical appliances now, there is a coice of more than one toast. There is also a better range of seasonal non foods, like clothes, shoes, garden furniture and camping gear.
