RE: Coral Reefs Could Go Extinct --- What Are People Doing to Reverse This?

You have to remember that coral reefs are a dynamic living ecosystem.

The coral constantly sends out babies that may or may not find a suitable environment to grow.

Trying to preserve a reef in a given area is an effort in futility as the normal planetary changes the environment in which they can thrive.

I understand the commercial benefits to having a reef stay put so that it can be commercially exploited, but the reality of environmental dynamics makes reefs dynamic as well.

Nice prizes!

It would be great to see a high-voltage (low current) power supply as a project using the transformers, especially if it was adjustable.

Both first and runner-up prizes look attractive.

I was considering buying that exact model hot-air tool at the start of the year, since it's extremely powerful (1kW).

In the end, I went with another model, but the MP740784 was in the top-three list. I believe it has a turbine type of fan, which is more reliable (and quieter).

The power helps to bring ICs up to temperature fast enough not to toast them. I did these two chips on the photo below, yesterday, using a hot air tool. There is a lot of copper heatsinking, so I really needed the power to get the solder up to temperature. A pre-heater helps too.
