Biotech, greentech and embedded systems are a few areas that look poised to keep growing and need a more significant amount of capitalization to get off of the ground.
but greentech will require more funding per instance than any VC firm will be able or willing to put up. show me the VC firm that is going to put over $1 billion into any single investment...when it comes to nuclear or hydrogen, a billion might only bootstrap the company. these industries are going to need massive amounts of funding. only one entity can do it - uncle sam, DARPA and the DOE
There are probably in thousands of potential greentech companies that could achieve profitability on 10 - 100 million. Probably the best example here is solar, as many companies already have achieved profitability, but there are tons of opportunities in fuels, materials, building technology, vehicle technology, water supply, agriculture, construction, data centers, refrigeration, industrial processes, road construction, and so on. There might exist companies you'd need to pump a billion into, but why attempt it?
There's a lot more to Greentech than energy or hydrogen fueling. Also note that most people don't consider nuclear power green. (Arguments of cleanliness aside, it's just usually one of the thing that green campaigners disapprove of.) My co-founder tonight met with the founder of greenvironment.com and I know that they're certainly not working in the billion-dollar range.
If you believe Al Gore, for $90MM you can build a giant New Mexico wind/solar farm that would supply enough electricity to power the entire US. (It's been a while since I saw the presentation so some details might be wrong but I am at least in the ballpark, especially regarding the price tag). Seems like 10 VC firms could easily get that sort of money together.
90 Million? The entire US? That's way off. I haven't seen the numbers, but that's like saying a car engine can get 1500% efficiency, or that a ten-year-old neighbor can bench-press 2000 pounds. It's just not in the cards.
when it comes to nuclear or hydrogen, a billion might only bootstrap the company.
One of the only giant LBOs that isn't a disaster area is the buyout of TXU. I would expect VCs to hand it off to PE guys if they had an asset that generated a steady, regulated cash flow.
