Prefab And Fabulous

Prefabricated homes can be smart choices when it comes to cost efficiency and time constraints. Soleta has designed a series of manufactured homes that are on the mark for their economical and ecofriendly features. They offer a zero energy version that comes fully equipped with hydroelectricity, solar and wind power. It is heated with thermal energy that is supplied by a system that combines geothermal and solar power. Cellulose is integrated in the building supplies to aid in retaining warmth along the base. Other sustainable and energy saving features include using materials that decrease heat transfer and energy loss. Additionally, there… read more

Solar technology may have just gotten even more exciting. Researchers at Massachusetts Institute of Technology have figured out how to utilize sunlight to convert it to energy more efficiently and with more control than a standard photovoltaic cell. Inventing a nanophotonic solar thermophotovoltaic instrument, they have uncovered a process which uses the sun to activate a temperature reactive material. The system uses both photovoltaic cells to generate energy as well as solar thermal energy, which is capable of storing power. Their device employs nanotubes made from absorbent carbon to caputure sunlight that is turned into thermal energy, and can then be… read more

What Really Happens To Food In The Microwave?

What Really Happens To Food In The Microwave?

Some experts say that microwave cooking is not a healthful way to heat foods. Some studies have even shown that using microwaves may decrease the nutritional value of foods. However, many households have one. So, what does microwave cooking really do to your food? First off, how do microwaves work? Microwaves are a form of electromagnetic radiation. Magnetrons, found inside microwave ovens, produce microwave radiation by discharging pulses of microwaves which bounce off of things they come into contact with, yielding an amount of energy. The process affects the water molecules that are found inside of food and increases the temperature…. read more
