Solar water heaters can provide temperatures up to about 70 degrees C…some innovations take it to about 100 or a bit higher. What is the highest temperature that concentrating solar thermal can provide?

Upto 200 deg C
Over 1000 deg C
350 degrees C
500 degrees C

Correct Answer
Over 1000 deg C

And here's something for you to take back

It used to be thought something in the range of 400-500 degrees C is the kind of high temperatures solar thermal, through the use of concentation (called concentrated solar thermal)

But there are new blokes around the world such as Synhelion who are now hitting 1000 deg C or even higher
