This should be useful

Here is a report of a solid-state technology that converts heat to electricity with 20% efficiency: http://newenergyandfuel.com/http:/newenergyandfuel/com/2012/09/20/heat-to-electricity-breakthrough-may-be-commercial-scale/

Sure looks useful to me.

    Bruce – looks like you’re looking for ways to get the LENR into electricity more efficiently. This one is pretty good now, and looks to be improved upon. The main problem with TEGs is that the electrons carry heat as well as electricity, so it’s a hard nut to crack.

    I’d suspect this could also be used as a heat-pump, which would give you quieter heating in your house. Maybe not yet as efficient as a gas cycle, but they look to be getting there.

    Great for powering air-conditioners in hell.

    • Jonathan Says:

      Actually it won’t work for powering air conditioners because you need a temperature gradient for it to work, it creates energy when heat moves from hot to cold, just like any heat engine such as steam or internal combustion.

      The air conditioner creates a temperature gradient by moving heat from cold to hot, generally with about 90% efficiency.

      Even if both were operating at 100% efficiency, the heat pump would use more every than the heat engine would recover.

      Rossi actually tried something similar before he got involved in LNER, but only managed 2% efficiency.

      This technology would probably initially be used in satellites in place of the sorts of thermocouples Rossi was experimenting with. Otherwise, steam engines are about 40% efficient, so we are likely to continue using them for some time. Both technologies will require a supply of cold water or similar to keep them working.

        Jonathan – it should be OK to use it as a heat-pump, though as with a standard Peltier block it’s not going to be as efficient as the gas-filled refrigeration. Just quieter.

        Funnily enough, the government reports on Rossi’s first TEG samples showed around 20% efficiency if I recall it correctly, but the factory he built them in burnt down and he only achieved 2% efficiency with the samples from the new factory so lost the contract. It’s inconvenient when the factory burns down. It’s even possible that the reported facts are true.

      Nice thing to have if you really want to get rid of the CO2. I wonder where the calcium comes from, though. If it gets put into mass use and the CO2 goes down, we’ll reduce the amount of food we can grow through lack of CO2. We’re currently in a pause of global warming, but the climatologists (having said 15 years was needed before the change in weather can be taken as climate change) have now said it’ll be another 5 years before they’ll accept they are wrong. Plan to get some form of LENR heating for 10years from now.

    If this works, I guessing it’s something similar to the cavitation phenomenon.

    GENERATING ENERGY FROM WATER

    For years people have been looking for a better way to generate energy. After splitting the atom, we were able to unleash the awesome power hidden inside this seemingly inconsequential particle. 70 years ago nuclear power was introduced into the world, bringing a false hope of cleaner and better life to the billions on this planet still living in poverty. Nuclear power turned out to be a very dangerous and expensive resource, similar in many ways to the power derived from burning coal with both having dangerous after effects, with either tons of dangerous emissions or tons of very dangerous spent fuel.

    We have discovered and filed patent apps for changing liquid water into super-heated steam mechanically.

    Our Mist Energy System is a SOURCE of power, and like the sun, virtually inexhaustible. Much like splitting the atom, we unleash the hidden power stored in the molecules of water. It is well known that intermolecular energy holds each and every water molecule to another. Since the earth is 75% covered in water, it is safe to say that we have a continuous supply of energy.

    We use the new technology of impact heating. At speeds exceeding 1700 meters per second our water clusters shatter upon impact with the chamber wall, thus creating tremendous heat and releasing the hidden energy in the liquid.

    The technology behind our system is simple. It is well known that both hydraulic power and its effect on fluid are both linear. For example, if you increase the power by a factor of three, your output and expense will increase by a factor of three. However, since kinetic energy is exponential, the energy derived from the speed of the water molecules in this example will increase by a factor of eight. Simple physics, abundant supply, and proven tests – Molecular Impact Steam Technology.

      Iggy – if it works (and I suspect it doesn’t since he’s open-sourcing it after a few years of trying to make it work) then it would need to work much like Nanospire, and would actually eat the cylinder walls it hit. This doesn’t seem to happen. There is maybe a little energy from making water into a fog, but that’s not that many joules and would most likely be swallowed by the inefficiencies of the mechanical bits. I wouldn’t hope for too much from this idea.

      • Craig Binns Says:

        It’s perpetual motion / free energy. Scam. Disguised by puffs of steam. Now where have we seen that before?
