Better Solar Energy Systems: More Heat,More Light
Solar photovoltaic thermal energy systems,or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’ta very efficient way to gather heat.
31. PVTs are not efficient in
A. creating electricity.
B. cooling silicon solar cells.
C. generating heat.
D. powering solar thermal collectors.
Face Masks May Not Protect from Super-Flu
If a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help, or harm,during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet.
Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing.
What’s killing the Bats
First it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats(Myotislucifugus,) but other species, such as the long-eared bat, the small-footed bat, the eastern pipistrelle, and the Indiana bat have also been affected, In some caves, more than 90 percent of the bat populations have died.
