More than half of our heat is put to waste, involving fridgeratorator and other utilites used in the house with a heat source. Most of everything we own have a heat system, like our cars. Our automibiles use more than 30% of our energy, which bring my point to we need a divice that converts wasted heat into electicity. Ole Martin Løvvik, is the man that came up with an idea to create sommething that takes our uneeded heat and use ait for something else. He calls it a Thermoclectric, and some of the matriels used for this device is used for space flights. The thermocletric will use solar energy, and other types of energy.Thermoclectric will be used in car generators for the extra heat the brakes recive and 0ther places in the car. Many major manufactures are already intrested in this product.
Ancient Climate Change Has Left a Strong Imprint On Modern Ecosystems
Title: Ancient Climate Change Has Left a Strong Imprint On Modern Ecosystems
Date:Oct. 10, 2011
Summary(8-10)
Between cold and warm seasons, animals migrate to climates they can handle so they can live.Scientists have mapped out how fast species have had to migrate to keep up with the climate change.They found smaller animals are living in areas that require little to no migration.The need for migration will increase with human activity, including building,which may put their lives at risk. About 21,00 years ago Earths climate was much colder, and many animals were forced to occupy other areas that they are not found in today.In some locations,high and low migration is required due to the earths recent climate change.Anthropogenic climate change is leading to increased climate-change velocities.These areas, by virtue of their historically low velocities, have high concentrations of small-ranged species.These species will likely be at particular risk as velocities increase over the next several decades.
What I liked and why.(4-6)
Learning about the animal extinction was interesting. What I liked was learning about how activities humans do will increase the risk of animal extinction.The more we build and move into an animals habitat will decrease the chance of those animals surviving anywhere else. Not thinking about what we do can really effect our animals. I liked it because learning about animals and how we effect them is interesting to me.
