1977
During the oil crisis in the USA there was shortage of fuel. Jimmy Carter's response was to request that the nation conserve fuel. He put on a sweater and announced on TV that he was turning his thermostat down to 55. He also got Congress to enact the Crude Oil Excess Profits Tax, actually an excess tax on crude oil.
The Iran hostage crisis was a diplomatic crisis between Iran and the United States where 52 Americans were held hostage for 444 days from November 4, 1979 to January 20, 1981, after a group of Islamist students and militants took over the American Embassy in Tehran in support of the Iranian Revolution.
Petroleum and uranium can be used as fuels.
Have you tried spraying gas intothe breather. Does it have tbi or multi-port? How about the fuel regulator. How much pressure does the fuel rail have ?
Burning coal, and nuclear reactors using Pu-239
By reprocessing spent fuel plutonium can be obtained, this can be added to uranium to make a mixed oxide fuel (MOX), so it is a form of recycling, though it is not the original U-235 that is recycled.
It can produce low grade plutonium that need be extracted from the used nuclear fuel through used fuel reprocessing. However, power reactors are subject to the international nuclear safeguards to prevent its misuse.

The reuse of spent fuel involves opening up the (spent) fuel elements and then processing the "insides" to recover unused fuel. The primary reason we don't do this is that it is extremely expensive to set up and run a facility that does this. It is generally cheaper to mine uranium out of the ground, process it to win the metal, and then enrich it to recover high percentage U-235 for use in making nuclear fuel. We might make a comparison to "simple" mining, refining and enrichment by looking at reprocessing. Reprocessing spent nuclear fuel involves exposure to highly radioactive materials. These pose a number of risks, and this means increased costs. The chemistry of reprocessing translates into costs for materials (like nitric acid to dissolve spent fuel in "step one" of the process). The end of the process leaves a stream of highly radioactive materials that need secure and long-term storage, and this does not come cheap. Though usable fuel has been recovered and reused via reprocessing, it's expensive. Reprocessing fuel is generally not as cheap as a "once through" fuel cycle where spent fuel is just pulled from the reactor after use, left sealed in the fuel elements, and then placed in long-term storage. Unless the price of uranium goes sky high, which, though possible, is unlikely.

One reason is that this enables plutonium to be separated out, and so gives the opportunity to make fission bombs. If the spent fuel is stored whole then this cannot happen. Apart from this, reprocessing is a messy chemical process with many chances of radioactive arisings being leaked to the environment-we have seen this at Sellafield in the UK.
In the United States, when a nuclear submarine has "run out of" nuclear fuel for its reactor (this takes many years), the reactor may be opened, and the spent fuel sent for reprocessing at the Naval Reactors facility at the Idaho National Laboratory. The reactor's core may then be refueled. This process can take some time, and handling the spent fuel is dangerous and requires complex procedures to prevent contamination. If the submarine is to be overhauled, or retired, the fuel is removed for reprocessing, and the reactor compartment is cut out of the submarine, sealed, and moved for disposal to the Department of Energy's Hanford Nuclear Reservation in Washington State, where they are kept in dry storage. The submarine may be welded back together, or the sections floated, until a new compartment and reactor are installed, or the vessel is cut up for scrap. Low level radioactive waste may be handled in other ways.
