This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Googling around, you get about 1e11 kJ/gram of He produced (source.
Wikipedia says Hindenburg volume is 200,000 m cubed . Multiply by density of He at stp and you get north of 1e7 grams.
Multiply and you get 1e21 J. Estimate for worldwide energy consumption in 2010, from Wolfram Alpha, is half of that.
So, if all energy were from local fusion, it would take about two years of production to fill a single Hindenburg-sized Zeppelin. That is a huge amount of energy.
I don't think it's equivalent to compare energy with RAM like this. Energy is the realm of thermodynamics; things like boiling water don't care about technology, they just need a certain amount of energy. Unless we're talking about fundamentally new uses of energy, like floating cities or something whacky, I think the amount of energy here is really, really big.
