exists and is an alternate of . Yes, it is possible to tear a hole (hernia) from lifting too much. In the case of lifting weights, most often the muscles in the lower abdominal area are affected. The muscles, especially weaker muscles, can tear from the extreme pressure/ strain put on them from lifting very Heavy weights.
Active Solar Design. Active solar systems use external sources of energy to power blowers, pumps and other types of equipment to collect, store and convert solar energy. Once energy from the sun is absorbed, it is stored for later use.
New material can store solar energy to warm you up later. A solid film releases a burst of heat just when you need it. Solar projects are usually focused on generating electricity, but we could arguably save more power by storing heat. Scientists from MIT have created a new type of solid material that does exactly that. When exposed to sunlight, it assumes a charged state that can be maintained for long periods of time.
