Only slightly related- but what endevours would become at how much energy output per $ Helium inserted viable? Has that been studied?
There must be a curve, where it can be estimated at what cost-point fission and solar are out- and for example growing ressources in vats becomes cheaper then farming/ chopping down natural grown wood.
What other "uneconomic" endavours become feasible with fusion at what price?
- ianai 9y agoCarbon sequestration - not sure on what price point, but at least the current cost of oil reserves. This factor should include national security 'returns' (the huge boon from moving away from middle east controlled energy) - so say trillions of dollars per decade. Salt water desalination - at some point pumping salt water (possibly long distances) to desalination plants for agricultural and domestic use becomes feasible. Space programs - once oil is disrupted as an energy source for the masses it will be cheaper to push things into orbit.
- TheSpiceIsLife 9y agoGenuine question: What does not using oil for mass transit have to do with reducing cost to orbit?

- ianai 9y agoI didn’t say mass transit.
- TheSpiceIsLife 9y agoYou wrote: > once oil is disrupted as an energy source for the masses I'm confused, what else do the masses use oil for? If I'm not mistaken the production of fuel for transportation is the lions share of oil use. But regardless, how does that help us get things to orbit?
- wpietri 9y agoThe phrase "mass transit" is generally used to mean public transit: https://en.wiktionary.org/wiki/mass_transit https://en.wiktionary.org/wiki/mass_transit
- TheSpiceIsLife 9y agoOkay, sure. At risk or repeating myself, what does any of this have to do with getting to orbit?
- Footkerchief 9y agoMass transit is public transportation, not all transportation. Many rockets use fuels derived from oil and other fossil fuels, e.g. kerosene and methane.
- TheSpiceIsLife 9y agoI meant mass transportation in the general sense, cars, busses, trains, planes. I just kind of typed the wrong thing. This article[1] claims Falcon 9 launch list price is $61.2 million and "Musk said the fuel used on a Falcon 9 is between $200,000 and $300,000." So the fuel cost is 0.5% of the launch price. It could be argued that if we stop using oil for transportation the price of oil derived kerosene and methane could go up as production scales down and fewer refineries sell in to the market. 1. http://spacenews.com/spacexs-reusable-falcon-9-what-are-the-real-cost-savings-for-customers/ http://spacenews.com/spacexs-reusable-falcon-9-what-are-the-...
