Apparatus and method for generating electricity. The apparatus includes one or more first components configured to extract heat from at least a first fluid flow at a first temperature to one or more devices configured to convert thermal energy to electric energy. The first fluid flow is in a first direction. Additionally, the apparatus includes one or more second components configured to transfer heat from the one or more devices to at least a second fluid flow at a second temperature. The second temperature is lower than the first temperature, and the second fluid flow is in a second direction. Each first part of the first fluid flow corresponds to a first shortest distance to the one or more devices, and the first shortest distance is less than half the square root of the total free flow area for a corresponding first cross-section of the first fluid flow.

1. A heat recovery system, the system comprising: a thermoelectric apparatus;a first duct coupled to the thermoelectric apparatus;a second duct;wherein the first duct and the second duct both are connected to a third duct and configured to receive by the first duct a first fluid flow at a first temperature from the third duct if the second duct does not receive the first fluid flow and to receive by the second duct the first fluid flow from the third duct if the first duct does not receive the first fluid flow;wherein the thermoelectric apparatus is configured to: receive at least a second fluid flow at a second temperature, the second fluid flow moving into the thermoelectric apparatus from one or more first perimeter parts of the thermoelectric apparatus in a first direction, the first direction being towards the second duct, the second temperature being lower than the first temperature;discharge the second fluid flow into a fourth duct, the fourth duct being the second duct or being substantially parallel with the second duct;receive at least a third fluid flow at the second temperature, the third fluid flow moving into the thermoelectric apparatus from one or more second perimeter parts of the thermoelectric apparatus in a second direction, the second direction being towards the second duct, wherein the second direction is opposite to the first direction; anddischarge the third fluid flow into a fifth duct, the fifth duct being the second duct or being substantially parallel with the second duct. 2. The heat recovery system of claim 1, and further comprising: a sixth duct coupled to the thermoelectric apparatus and connected to the third duct;wherein the sixth duct is configured to receive a fourth fluid flow at the first temperature from the third duct if the second duct does not receive the fourth fluid flow and wherein the second duct is configured to receive the fourth fluid flow from the third duct if the sixth duct does not receive the fourth fluid flow. 3. The heat recovery system of claim 2 wherein: the first duct and the second duct share a first sidewall; andthe second duct and the sixth duct share a second sidewall;wherein the first sidewall and the second sidewall are configured to: move to a first position and a second position respectively in order to provide the first fluid flow to the first duct but not to the second duct and in order to provide the fourth fluid flow to the sixth duct but not to the second duct; andmove to a third position and a fourth position respectively in order to provide the first fluid flow and the fourth fluid flow to the second duct but not to the first duct and not to the sixth duct, the first fluid flow and the fourth fluid flow being received by the second duct together as one fluid flow. 4. The heat recovery system of claim 1 wherein the thermoelectric apparatus is a thermoelectric system. 5. The heat recovery system of claim 1 wherein: the first duct is a first chimney;the second duct is a second chimney; andthe third duct is a third chimney. 6. The heat recovery system of claim 1 wherein the thermoelectric apparatus is further configured to discharge the second fluid flow into the fourth duct through a seventh duct. 7. The heat recovery system of claim 1 wherein the thermoelectric apparatus is further configured to discharge the second fluid flow into the fourth duct, the fourth duct being parallel with the second duct. 8. A method for heat recovery, the method comprising: receiving, by a first duct, a first fluid flow at a first temperature from a third duct connected to both the first duct and a second duct while excluding the first fluid flow from the second duct, the first duct being coupled to a thermoelectric apparatus, the second duct being configured so as to fluidically bypass the thermoelectric apparatus;receiving, by the second duct, the first fluid flow from the third duct so as to directly exhaust the first fluid flow while excluding the first fluid flow from the first duct;receiving, by the thermoelectric apparatus, at least a second fluid flow at a second temperature, the second fluid flow moving into the thermoelectric apparatus from one or more first perimeter parts of the thermoelectric apparatus in a first direction, the first direction being towards the second duct, the second temperature being lower than the first temperature;discharging, by the thermoelectric apparatus, the second fluid flow into a fourth duct, the fourth duct being the second duct or being substantially parallel with the second duct;receiving at least a third fluid flow at the second temperature, the third fluid flow moving into the thermoelectric apparatus from one or more second perimeter parts of the thermoelectric apparatus in a second direction, the second direction being towards the second duct, wherein the second direction is opposite to the first direction; anddischarging the third fluid flow into a fifth duct, the fifth duct being the second duct or being substantially parallel with the second duct. 9. The method of claim 8, and further comprising: receiving by a sixth duct a fourth fluid flow at the first temperature from the third duct if the second duct does not receive the fourth fluid flow and receiving by the second duct the fourth fluid flow from the third duct if the sixth duct does not receive the fourth fluid flow, the sixth duct being coupled to the thermoelectric apparatus and connected to the third duct. 10. The method of claim 9 wherein: the first duct and the second duct share a first sidewall; andthe second duct and the sixth duct share a second sidewall;the first sidewall and the second sidewall moving to a first position and a second position respectively in order to provide the first fluid flow to the first duct but not to the second duct and in order to provide the fourth fluid flow to the sixth duct but not to the second duct; andthe first sidewall and the second sidewall moving to a third position and a fourth position respectively in order to provide the first fluid flow and the fourth fluid flow to the second duct but not to the first duct and not to the sixth duct, the first fluid flow and the fourth fluid flow being received by the second duct together as one fluid flow. 11. The method of claim 8 wherein the thermoelectric apparatus is a thermoelectric system. 12. The method of claim 8 wherein: the first duct is a first chimney;the second duct is a second chimney; andthe third duct is a third chimney. 13. The method of claim 8 wherein the thermoelectric apparatus further discharges the second fluid flow into the fourth duct through a seventh duct. 14. The method of claim 8 wherein the thermoelectric apparatus further discharges the second fluid flow into the fourth duct, the fourth duct being parallel with the second duct.
