The most common renewable energy resources used in the Nordic nations are hydroelectric and?
biothermal, hydroelectric
How can we release the energy inside say a pumpkin to produce electrical energy?
Waste vegetable material can be fermented to produce methane which can be burned or used in a heat engine to drive a generator. This is renewable energy which means we are able to use less fossil fuels (coal, oil and natural gas) to generate electricity.A:You can eat the pumpkin, and then attach your bike to a dynamo machine and charge up your batteries. With the waste material, you can buy a Biothermal generator. I don't know how much these cost, or even if small ones are available to the general public. Some countries use Biothermal power plants to turn the methane given off by rotting material into energy.
Natural source of heat?
There's the sun, Obviously. And there's Geo-thermal Energy which is the heat from the earths core, it is released it different ways, geysers, volcanoes, thermal vents.. also radioactive rocks will give of heat
Why do Rhinos and Pigs like mud?
Mud helps suffocate parasites and lice and also serves as a natural sun block to keep the hot sun off of the bodies of rhinos and pigs. It is a biothermal response to their lack of ability to dissipate heat; they immerse themselves in the mud if there is not a large round tub of cool water for them to bathe themselves in or if it is too dry for any mud to be found. Pigs do not have any sweat glands; therefore they cannot sweat. Rolling in mud cools them down.
Why do pigs love mud?
Pigs cannot sweat, and therefore cannot keep themselves cool like we humans can. Mud helps suffocate parasites and lice, and also serves as a natural sun block to keep the hot sun off of their bodies. It is a biothermal response to their lack of ability to dissipate heat; they emerse themselves in the mud if there is not a large round tub of cool water for them to bathe themselves in, or if it is too dry for any mud to be found. Pigs do not have any sweat glands therefore cannot sweat and that is why they roll in mud to cool them down.
