Sunlight output is about 10^17 watts, and we only need 10^13 watts. This is 10k more then we currently need. Increased effectiveness of nanotechnology implies energy requirments will only oncrease to 3x10^13 by 2030. We can meed this energy need with 0.0003 of the sun's energy.

Solar panals have been relatively inefficient and expensive, but technology is rapidly improving.
Stedily advanced for silicon photovoltaic cells from 4% in 1952 to 24% in 1992. Currently around 34% efficiency. Effectiveness above 60% seems attainable.

Today it costs $2.75 per watt. The price will fall, and once it does fall below $1.00, it will be competitive for directly supplying electricity to the nations grid.

Currently, the price sits as low as $0.70 cents per watt.

Once we have molecular nanotechnology based manufacturing, can produce solar panels extremely ineffictively, basically at the costs of raw materials. Could eventually be as inexpensive as a penny per square meter. Could put solar panels everywhere, on buildings, majority of human surfaces.

Could put solar satellite into space and beam to earth via microwave. Each unit could provide billions of watts of electricity.

Medicine

New ECG analysis for long-term unobtrusive monitoring, detect early warning signs of heart disease.
AI programs to do pattern recognition and intelligent data mining in development of new drug therapies. Intelligent datamining tools to find new ways to distupt metabolisms of pathogens.

CPOE checks for every order for possible allergies in a patient, drug interactions, duplications, drug restrictions, guidelines, ect.
Patter recognition applied to protein pattern patterns can better detect ovarian cancer.

Augmentations

197
Billions or trillions of nanobots can be put into the bloodstreem.
Use to scan the human brain to reverse engineer it.
Blood cell replacements will perform hundreds or a thousand times better then their replacements.
Microbivores will be more effective then white blood cells.
Mend DNA transcription errors, and implement DNA changes.
Other robots can serve as cleaners, remove unwanted debris and chemicals from cells.

Brain in the 2020s, begin augmenting our brains with nonbiological intelligence.

Start with functions of sensory processing and memory, moving to skill formation, pattern recognition and logical analysis.

By 2040, non biological portions of brain will be millions times more capable.
“”Although we are likely to retain the biological portion for a period of time, it will become of increasingly little consequence.””
