That's what Drax power station uses for a renewable source. Yeh, I was aware that "biofuel" is an trendy thing these days to the scientifically illiterate. We ban smoking, but there isn't a lot of difference between burning wood and tobacco. That's nonsense. The fuel for cooking maybe. And you don't intentionally in your lungs. |

The cancer causing by-product is in wood smoke as well as tobacco smoke. It's due to partial combustion at about 300C. Any cellulose material has this property. Learn your science. |

You don't intentionally use the wood smoke. You deliberate inhale cigarettes in your lungs. Learn to understand the difference. And, while you are at it, learn that rate of kW. |

You forget the passive smoking hysteria. Actually barbecues have the same characteristic and you do intentionally eat that. I'm just pointing out a sociological phenomenon here. Cigarettes very bad/barbecues, renewable biofuels good. |

Cigarettes very bad/barbecues, renewable biofuels good. It's not quite the same as Drax. "Biomass fuels are typically burned in low-efficiency stoves with poor ventilation, and incomplete combustion generates high concentrations of air pollutants including various noxious gases and particulate matter" Drax is a very high efficiency plant. And a non-smoking environment. |

And a non-smoking environment. I grant you that proper burners help to reduce the problem but then on the negative side is the sheer quantity burnt. The beauty of my proposed system it it does not burn anything. The sand will never wear out. The only drawbacks are the insulation side of it and the fact the heat engine does often use moving parts so will need some servicing and will have a finite life. Indeed I wonder if we can re-engineer solar panels so they last forever. Perhaps it is the UV that destroys them. It's a good research project to develop that side of it as well. Nothing needs to move with solar panels. |

You would want to have pipes running through it so when charging it up you run some liquid through the pipes from the electrical heater. When you discharge it, you switch the pipes to flow in a loop from the heat pump. You should only ever want to do the one or the other at any given time, so only one set of pipes are needed. Obviously these pipes need to be made of a high melting point material. |

In a toolbox I have an old "Duracell" torch with 2 AA batteries. I checked it the other day and it is still working and the batteries are in good condition according to my battery tester. I changed the torch bulb for an LED bulb and it works a treat.
The batteries have an "expiry" date of 2011 on them. I'm amazed how long they have stayed useable.
Perhaps Duracell batteries are the answer, seems much more viable than heating sand from inexplicable power sources.

Obviously these pipes need to be made of a high melting point material. I'm lost here. Take it one step at a time for my simple brain. How do you charge the heating on the pipes ? You use ohmic heating.
However that just gave me an interesting idea because a heat pump could be used. You see if we go back to the entropy calculations, the act of heating some wire with electricity is an irreversible process. What you have done here is made an ordered system become disordered and as such it is impossible for that state to go back to an ordered state as per the second law of thermodynamics. An example of a reservable process is adiabatic expansion. So this is why when you use a heat pump you get more bang for your bucks than a straight forward heater, but the efficiency gain is inversely proportional to the temperature difference. So as we raise the temperature to 1700C our heat pump gives us less and less over unity advantage, but at the same time the recovery back to electricity gets higher efficiency. It would therefore be interesting to feed all this into an equation and work out the optimum efficiency when we use a heat pump. If every process were totally reversible the efficiency would be 100%. It can never be higher because that is the act of making a perpetual motion machine. (Noether's theorem says No!!)

You are still not grasping it. Yes, it is Ohmic hearing. Who pays for it? Who heats all that bloody sand ?? I'm still waiting. |
