Because even if you get it, you may not like paying the bill.
The US energy situation is suffering — actually suffering — not from too little oil, but arguably too much. The costs of getting what we have are far greater than the pump price, and going upwards.
But that's not the biggest problem. The main problem the USA has isn't an immediate lack of oil or natural gas. It's a lack of imagination.
Imagination? Yes. What other other name is there for a situation where people refuse to reconsider what they desire in light of what it costs, and what they actually need? When people head closer to bankruptcy every time they fill the tank on the 3-ton vehicle they bought, and demand cheaper goods from others instead of changing their own habits?
This is not just a psychological problem. It leads to escalation of failure, which can be disastrous.
All of this could be fixed relatively easily if people would use their imagination to figure out what they really want, and how best to get it. Consider:
So let's exercise that flabby imagination and consider what we'd ask for to get just what we want, without all those pesky consequences.
When I'm at home, I don't give a rat's ass about electricity per se. It's a means to an end. One thing I want is for my house to remain comfortable in the summer. I can do this with an electric air conditioner, or I could pump cold water out of the ground and use it to cool the air in my house. I could use solar heat to dry a dessicant and use that to remove the clammy humidity. My electric needs would decrease to what's needed to run some fans and a water pump. Good architecture (roof overhangs on sun-facing walls, awnings or other exterior shades, windows which can replace hot stagnant air with cool outside air) can make the house far more comfortable without any energy use at all. Demanding lots of electricity would cost me a bundle; a little imagination would make me comfortable for a lot less money.
Same thing about natural gas. If my hot water tank and house stay toasty without burning gas, do I care whether it comes to my house or not? If I don't need any, why would I care what it costs? With good insulation and the right architecture, I could be comfy without natural gas and pay a lot less money. I'm sure spermaceti candles cost a king's ransom these days, but I don't care; I have more and better light without burning a thing in my house. Neither do I need "rock oil" except perhaps to establish a mood.
Gasoline? Technically I don't use it any more, but my diesel car still burns petroleum. I'd have the same utility and a lot less expense and inconvenience if most of my driving was powered by electricity. Plugging in every night or two would be less hassle than going to a filling station once a month to pump smelly liquid into the car's tank, and it would be quite a bit cheaper.
The pursuit of petroleum and natural gas is costing us a huge amount of money, and building up debts which will be with us for generations. A little imagination could give us the same or equivalent goods and cost us a lot less (in several different ways). Isn't it time to get our minds out of their ruts and ask for something a little different?
It looks like my spec for 50% efficiency in the gas-to-electricity step in Sustainability may have been pessimistic; Fuel Cell Today had an article last year which claimed the possibility of 80% efficiency (see page 4). (I claim overwork as an excuse. Yeah, that's it.)
Further, this is not from a SOFC, it's with a turbine-compounded MCFC. With this sort of efficiency, it would be feasible to dispense with SOFC's entirely. This is the sort of backup technology which practically guarantees that the concept is viable. The one element I cannot pin down is cost.
In other news, LiFePO4 cells are heading toward commodity status.
Of all the surprises I've had this year, the biggest was probably these words from the head of GM:
First, electricity offers outstanding benefits... beginning with the opportunity to diversify fuel sources upstream of the vehicle. In other words, the electricity that is used to drive the vehicle can be made from the best local fuel sources—natural gas, coal, nuclear, wind, hydroelectric, and so on. So, before you even start your vehicle, you're working toward energy diversity.
I could have sworn I'd heard similar sentiments before:
if you can make your own "motor fuel" with a solar panel or wind turbine, you will be largely insulated from oil depletion.
Mr. Wagoner continued:
Third, electrically driven vehicles offer great performance...with extraordinary acceleration, instant torque, improved driving dynamics, and so on.
This also sounded familiar:
A car that's quieter, runs its A/C at full speed even when the engine is at idle (or even with the engine off), has superior power steering, can run many kilowatts of electrical loads... is a better car no matter how you cut it.
If the auto isn't going to decline along with the production of oil, it's going to have to shift from petroleum to renewable energy. Maybe the industry (and the nation) won't drop the ball this time.
Evidence accumulates that the biofuel recycling step in Sustainability is not only feasible, but here today: Greenfuel just announced production of commercial-quality biofuels from CO2 scavenged from an Arizona powerplant (h/t: Cervus @ GCC).
Further, they mentioned that the CO2 capture efficiency is as high as 80% during daylight hours. This is astounding, and it strongly suggests that a closed-loop system is feasible:
So long as the volume of the greenhouses is large enough to store CO2 and supply oxygen overnight, this requires no exhaust to the atmosphere; it can turn all biomass input into electricity PLUS liquid biofuels. It could even burn its own biofuels to make carbon-free electricity, cycling the carbon in a closed loop. We don't need fuel cells right away; we can start with small gas turbines and work up from there.
What are we waiting for?
