- Comment on Renewables cover more than half of Germany’s electricity demand for first time this year 11 months ago:
Moving goods vast distances over land extremely cheaply and with zero carbon emissions is a problem that was solved long ago with overhead electrified rail, and it’s amazing to see the lengths we here in North America will go to avoid investing in it.
i hope that this falls in the same line but in Germany they rather tow double trailers on the Autobahn (highway) instead of shipping by rail (which is maybe slower) while destroying highways in the process, and costing the taxpayer money to be repaired. So shipping companies like Hermes® would ship you products at a cheap price but is in fact stealing tax money from the taxpayer indirectly

goods should only be transported on rail, period. i agree about the rest.

but heavier cars ruin the road structure. Highways need an alternative for bitumen, and overall electrify the production of road components, including steel and concrete.

gasoline is 100 time more energy dense than electricity, thus even inefficiencies at 70% for IC engines, gasoline would still be more efficient somehow. But there is alot of geopolotics and environement involved with fuel. The problem of energy density needs to be resolved somehow so it would be more convenient to use.

electricity is cool, but its not the only source of energy used in the country: fuel is also a source of energy and needs to be replaced. The amount of electricity consumed in France is about 470 Twh, and the amount of Joules used overall is equivalent to 1500 Twh, per year.

unpopular opinion but true: they took advantage of a legal loophole and they cashed on it. Legal counseling really pay up dividends.
- Comment on How to Make Biofuel at Home 11 months ago:
i dont know what you are implying with this, but the whole idea still involves methanol and diesel that are hydrocarbons, and thus still require tankers and refineries to carry oil around and refine it. is it a worthwhile idea ? idk. is it better than lithium mining ? maybe (at least oil is way abundant than lithium). by how much would this reduce carbon emissions ? 90% ? still up for debate.

How to Make Biofuel at Home: From Crop to Car
Using biodiesel requires modifications to the vegetable oil itself; using straight vegetable oil requires modifications to the diesel engine.
The engine starts on diesel fuel, but switches to run on vegetable oil after heat produced by the engine warms the vegetable oil to about 160 degrees Fahrenheit.
Before shutting off the vehicle, diesel fuel is cycled through the fuel lines to purge the system of vegetable oil.
A single-tank system preheats the vegetable oil using electric heat and uses modified injectors and glow plugs that are optimally suited to ignite and combust vegetable oil.
Thanks in part to a grant from the National Center for Appropriate Technology, an organization that promotes technologies that conserve energy and resources, we have retrofitted a Kubota tractor with an Elsbett single-tank fuel system to run on straight vegetable oil produced in eastern Montana.
If we confirm that a single-tank system is a viable option for running a tractor on straight vegetable oil, we plan to grow an oilseed crop and produce our own fuel.
The PEAS farm also houses a biodiesel processor to convert used cooking oil to biodiesel for the Garden City Harvest tractor.
Basically, biodiesel is produced by a chemical reaction involving vegetable oil, methanol, and potassium hydroxide or another catalyst.
We took 20 gallons of used fryer oil, strained out the food particles, and pumped the oil through a series of braided hoses and copper valves into a recycled water heater.
As the oil cycled through the processor, we took a sample and tested it to determine the amount of potassium hydroxide we would need to add to the used oil.
From 20 gallons of used fryer oil, we produced 16 gallons of biodiesel.
Utilizing salvaged materials, the biodiesel processor at the PEAS farm was put together for about $150. Local restaurants give away used vegetable oil, and methanol can be purchased for $4 per gallon.
The legal issues concerning use of veggie oil as a fuel and home production of biodiesel are complicated and vary from state to state.
Laws concerning straight vegetable oil are changing, but it’s still technically not approved for use as fuel by the EPA. And your state may require you to register to collect waste vegetable oil.
The use of straight vegetable oil has demonstrated promise as a fuel alternative for our Kubota tractor.

yea, there is nothing record about that number. But journalists need clicks to get food on the table :/
