Solar Power Weather Station

lately in Australia we've had extremely hot days, high 40s Celsius in multiple cities.... the power grid really struggled to handle the pressure, train track literally buckled and the best authorities could do was say people should turn off their DVD

Generally, in order to generate usable power from heat you need something cold too. The power generated by a device (such as a stirling engine) is generated due to the difference in temperature between the hold and cold sides. The cold gets...

Spring through Summer, 2010, our cabin in the mountains was built. This movie is a compilation of about 12000 images taken at 5 minute intervals ...

I am doin a project for electrical systems and have been given the task of designing a remote weather staion. It has to be solar powered and someone has to be able to stay there for a couple of days, can anyone recommend websites or books where i...

I hope that the following sites will satisfy your needs.

I've just had a solar HWS installed with a manual electric boost switch. I know you can get timer switches, but I'm looking for a "smart" switch.
I've had it for a month without having to boost at all. A timer would have been wasting

My system has it built in. When it isn't sunny enough to heat, the electric comes on in time for the daily use. The "smart" isn't in the controller, it is in the use of a standard timer from your local hardware store, and the the...

1. Which occurrence is not characteristic of global warming? (1 point)
melting mountain glaciers in the South Pole
stabilization in the sea level due to warm weather
greater amounts of precipitation
loss of habitat...

1.) B
2.) D
3.) A
4.) C
5.) C
6.) D
7.) B
8.) C
9.) A (unless they mean the depletion of ozone and that occurs in polar areas
10.) B

i'll take my 10 points now

an environmental monitoring station is battery powered. assume that one fresh LongLife 1.35 V cells stores 1.5 KJ of useable electrical energy before its output drops below an acceptable value. two such cells are connected in series to provide 2.7...

Power = voltage x amperage = violts x current = P = V I

Energy = Power x time of operation = E = P t

So time is t = E/(V I)

Now you have two batteries with a total of 3 kJ on energy, V = 2.7 V and I...
