Energy Density of Some Materials (KHW/kg)
Energy density storage drives the choices that can be made. Technology helps to drive this. As discussed previously, energy storage in batteries is not sufficiently high to solve the basic problem.
Technical Overview of Energy Storage
Hence The Advanced Battery Consortium
Last time we talked about
The model with the small yellow disc tends to stop when the crank and connecting rod are in a straight line ('dead' spots) - because sliding the brass knob exerts no turning force on the shaft. In the model with the big yellow flywheel, it is easy to keep the disc turning, once it has started, due to the effect of the flywheel. The mass and the size of the big flywheel helps resist the slowing down of the model as it is turning.
Has high energy storage capacity compared to the alternatives. About 10 times higher per cubic meter than water.
One example (in Germany) to date:
For gases, Pressure is directly related to Temperature (Ideal Gas Law)
Go to the pressure chamber JAVA applet
If the temperature of the air at 1 atm is 20 C, how much will the temperature raise if we increase the pressure to 100 atm.
In general, pressure and temperature between gases is related as
For an ideal gas, n = 1 in above. Air is not an ideal gas and it has n = 1.4 Temperature is measured in Kelvins .
so you get
100.286 = 3.73
T2 = 293*3.73 = 1093K = 720 C
which would melt the salt reservoir!
