Not sad, just paying attention to how cooked it is

Looks like renewable energy has solved it's intermittency problem.
Man, this has really owned the greenies! Worse still they want to convert hydrocarbons into hydrogen  LOL Why would anyone pay for hydrogen when they can charge up their battery electric car for nothing from rooftop solar  LOL Totally brain dead liberals as usual. Hydrogen isn't a replacement for EV. It's a replacement for traditional petroleum. It's a replacement for coal and batteries. Hydrogen can be made by any source then used to create leccy. Apparently the tech to go from solar to hydrogen to leccy has just passed an efficiency milestone to make it viable. That's totally brain dead !! Why would i want to pay scumos cronies for their hydrogen rubbish when I can charge up a battery EV directly from rooftop solar ?? Doesn't make any sense to pay for others solar PV to generate hydrogen  LOL Let's be clear, EVs can't do what Petrol cars can now. We know this.But, EV is still more efficient in terms of energy required to power, than HFC. So HFC will be the future for anything, not just automotive, where the battery limitations are involved. So freight transportation, long drives etc. But like EVs need electricity to charge their batteries, HFC requires electricity to produce the hydrogen. We still need a clean way to create that electricity in large volumes. We're at the point where being glued to a single technology is as bad as partisan politics. We will need a mix of different technologies for different applications to overcome our current issues. It's going to be a mix of Renewables, home renewables, Nuclear, Coal, Hydrogen "storage", HFC Cars and EVs. What can't they do ??? My regular commute, in the before time, was about a 300km round trip, 3 days a week, with 150km the other 2, but that's just to head office. I would regularly have to drive to the individual sites, often 5 in one day, from Byron Bay to Noosa. I can't rely on an EV to have that sort of range. Plus there is bugger al charging stations up this way, although it's getting better. But it is pretty amazing you can see where they are and how many stations are free when needed and have that factored into the nav etc. I almost bought a Tesla last month, but I had to be practical. In the end, went for the hybrid Rav4. But that's just a regular Joe's workweek. I'm talking commercial application, freight etc. Maybe one day, but there is that fine ratio of power needed to cart around the batteries vs what's left for the actual vehicle and its load, sort of like launching things into space where batteries efficiency needs to improve. And it is. But the argument used against HFC applies here, EV and current batteries are just not ready. Tesla are making great strides and they Truck looked great, but the specs just aren't there, yet. But HFC has none of those problems but even then it is a replacement for standard fuels, not EV. They will always be side by side, if HFC ever gets off the ground, which like EVs, unless a billionaire comes in and starts trying to get the tech mainstream, there are too many vested interests and lobby groups in the way. Doing longer trips won't really give you optimal efficiency from your Hybrid tho. What a pity they didn't make a plug-in version you could get 50km of pure electric from. I like the Rav but need something bigger so will look at a hybrid Kluger/Santa Fe in 2 or 3 years. Yeah, they are all downfalls of it, but it's better than nothing.
