    As an engineering consultant, I do in fact have a copyright on the design documents I produce. If I really wanted to, I could sue a former client if they attempt to continue using my designs. They are licensed, not sold.

    And if I shelve a project (or more appropriately, walk off a job - which I've done) then all that really happens is I'm no longer legally responsible for any shit that goes down from that point on. I can refuse to deliver finished project documents, oversee the project construction, and address issues that arise during and after installation.

    And just because your name is on a patent doesn't mean you own the rights. Must be one of those situations where the stipulation of your employment at a company means anything you create belongs to them? If so, then that's what you agreed to and that's what you get.

    There's no such thing as a free market.

    Someone will always jockey for a position of dominance, because that's how capitalism works. The result is monopolies, robber barons and corporate oligarchy. Or it can go to the other extreme, where all trade is strictly regulated and controlled by third parties (eg governments). The result is the ideal case of socialism where everything is effectively owned and operated by everyone.

    The reality in practice is always a mix of these two; some combination of dominant corporate influences and government regulations that attempt to keep them from running completely roughshod over the economy. This in no way resembles the "free market" that everyone learns about in high school economics class because that's just a simplified, idealized example and not a tenable economic model.

    Excusing you from something *everyone else* has to do - eg pay taxes - is a form of subsidy. It's special treatment. It's a benefit.

    A subsidy is any form of financial assistance. If someone else pays your bills (a tax writeoff on equipment is exactly equivalent to having someone else contribute the taxable value of that equipment) then it's a subsidy. The taxpayer is picking up some or all of the cost of doing business.

    But fine, if you only want to include direct payments - The fossil fuel industry receives billions in direct payments. $3.4 billion in cash (grants) and another $1.3 billion in preferential loan guaranteed as part of the Recovery Act in 2009. Everyone complains about the $535 mil Solyndra got but nobody seems to care that they gave the oil industry nine times as much cash when they didn't even need it.

    Sometimes subsidies are warranted and justified. It's not justified when the person or entity receiving this perk could handily get by without the preferential treatment. If people making over $15,000/yr don't qualify for earned income tax credit, why should a company making billions in NET profit qualify for tax writeoffs and other benefits?

    How are you defining "Easy."

    Let me preface this by saying that storage is, in fact, largely overrated for solar power. The vast majority of our energy needs occur during the daytime. Storage is really really nice to have, but is not entirely necessary unless you are producing much more than you need and don't want to waste it (see: Germany)

    That said, let's talk "easy"

    On a technical level, it's far easier to store electricity. Just need a battery or capacitor. If you want a more general form of solar energy as heat, then you just need a storage medium like water or oil or molten salt or whatever. Very easy and these storage mechanisms generally last a very long time with little maintenance if built properly.

    Storing natural gas is a lot harder, again on a technical level. It's lighter than air and a fire/explosion hazard. It's moderately low energy density means it needs to be stored under pressure, so you need compressors and pumps to move it around. This means the very act of storing and transferring needs additional energy from secondary source - usually electricity.

    If you define "easy" in terms of final stored density, then yes natural gas wins handily - especially if you liquefy it. But higher density storage requires more energy input, so your efficiency (energy invested in storing the fuel versus energy in the fuel itself) starts to drop.

    If you define "easy" as recoverability, then it's a bit more complicated: batteries and capacitors give up their energy readily. Thermal storage requires an extra step to convert to electricity, if electricity is what you want... if you want heat then no conversion is necessary and again it's super easy to take out of storage. Natural gas can either be burned directly from storage if you just want some fire, or it could need converting into something else like mechanical power or electricity which are extra steps. You really need to define what you want to use the energy for to compare them, and they all have their strengths and weaknesses.

    If you define "easy" in terms of infrastructure/investment required, that also gets a bit murky. Natural gas already has the benefit of decades and billions of dollars in storage and transport infrastructure development. Thermal energy has only modest transport infrastructure (district heating/municipal steam systems) and not much int he way of storage. Electricity has excellent transport infrastructure but storage is still in its infancy compared to natural gas... you can find the odd pumped hydro station or massive battery bank but most electricity storage is low energy/high power used for smoothing out spikes and sags.

    With regard to your anecdote: Whomever designed it needs a kick in the balls, that's all. There is no sensible reason why a properly selected pump, for example, would fail every two years because of "too much heat." I'm a mechanical engineer with 16 years of HVAC design experience and I've never heard of that. Corrosion is not really a function of temperature - I suppose at the chemistry level it is, but a good and proper tank will be either coated or cathodically protected or both. There are tanks 50+ years old still in service because they were properly designed and installed. Sorry to hear of your troubles but it's just not the technology's fault.

    As for tipping point: You're wrong. Solar is becoming more affordable and more common every year. There are more solar power installers popping up every day it seem. It's a booming industry. It makes economic sense for many homeowners and businesses, and with the various subsidies the payback is typically under 10 years - often under 5. That means whomever installs solar will see a net savings after that time, and that means they have more money to put back into the economy.

    The same is not true for oil and gas companies that are already making obscene profits. Subsidizing them does not put more money into the economy nearly as efficiently - it just pads their bottom line and benefits a relative handful of CEOs and shareholders. They are fully capable of doing everything they do now without one dime of government money or tax write-off and still being one of the most lucrative industries on the planet.

    Venture capital and bank loans require a knowledge and quantification of risks. These people want to know when they'll get their money back, and how much profit they can expect to make.

    When you are doing things that are very much worth doing (there are lots of great reasons to develop renewable energy; economic, national security, AND environmental) but do not have either clearly defined risks or payback schedules, then you will have a VERY HARD TIME securing capital for those projects. This is exactly the best time for governments to step in and provide that capital. It is not until there is a clear business case that you'll be able to get much in the way of private funding.

    We are close to a tipping point with solar PV. Prices have fallen and now it's really installation costs that are the lion's share of a complete system. Businesses - from manufacturers to installers - have taken advantage of the subsidies offered by all levels of government and private industry alike and built business models around PV installation. It's not *quite* self sustaining yet, but it very well could be very soon. I'm perfectly okay with my tax dollars going towards expanding renewable energy.
